+
+ tsec: report when there is no vendor specific PHY support
+
+ Commit af1c2b84 added a generic phy support, with an ID of zero
+ and a 32 bit mask; meaning that it will match on any PHY ID.
+
+ The problem is that there is a test that checked if a matching
+ PHY was found, and if not, it printed the non-matching ID.
+ But since there will always be a match (on the generic PHY,
+ worst case), this test will never trip.
+
+ In the case of a misconfigured PHY address, or of a PHY that
+ isn't explicitly supported outside of the generic support,
+ you will never see the ID of 0xffffffff, or the ID of the
+ real (but unsupported) chip. It will silently fall through
+ onto the generic support.
+
+ This change makes that test useful again, and ensures that
+ the selection of generic PHY support doesn't happen without
+ some sort of notice. It also makes it explicitly clear that
+ the generic PHY must be last in the PHY table.

+ 8360, kmeter1: added bootcount feature.
+
+ add CONFIG_BOOTCOUNT_LIMIT feature for 8360 CPU.
+
+ The bootcounter uses 8 bytes from the muram,
+ because no other memory was found on this
+ CPU for the bootcount feature. So we must
+ correct the muram size in DTS before booting
+ Linux.
+
+ This feature is actual only implemented for
+ MPC8360, because not all 83xx CPU have qe,
+ and therefore no muram, which this feature
+ uses.

+
+ Currently we assign first_busno = 0 for the first PCIe hose, but this
+ scheme won't work if we have ordinary PCI hose already registered (its
+ first_busno value is 0 too).
+
+ The old code worked fine only because we have PCI disabled on

+ "mpc83xx: fix PCI scan hang on the standalone MPC837xE-MDS boards").
+ But on MPC837XERDB boards we have PCI and PCIe, so the bug actually
+ triggers.
+
+ So, to fix the issue, we should use pci_last_busno() + 1 for the
+ first_busno (i.e. last available busno).

+ netloop: speed up NetLoop
+
+ NetLoop polls every cycle with getenv some environment variables.
+ This is horribly slow, especially when the environment is big.
+
+ This patch reads only the environment variables in NetLoop,
+ when they were changed.
+
+ Also moved the init part of the NetLoop function in a seperate
+ function.

+ smc911x_eeprom: new example app for managing newer SMC parts
+
+ A forward port of the last version to work with the newer smc911x driver.
+ I only have a board with a LAN9218 part on it, so that is the only one
+ I've tested. But there isn't anything in this that would make it terribly
+ chip specific afaik.

+---------------------------------
+ Ethernet Address (MAC) Handling
+---------------------------------
+
+There are a variety of places in U-Boot where the MAC address is used, parsed,
+and stored. This document covers proper usage of each location and the moving
+of data between them.
+
+-----------
+ Locations
+-----------
+
+Here are the places where MAC addresses might be stored:
+
+ - board-specific location (eeprom, dedicated flash, ...)
+ Note: only used when mandatory due to hardware design etc...
+
+ - environment ("ethaddr", "eth1addr", ...) (see CONFIG_ETHADDR)
+ Note: this is the preferred way to permanently store MAC addresses
+
+ - ethernet data (struct eth_device -> enetaddr)
+ Note: these are temporary copies of the MAC address which exist only
+ after the respective init steps have run and only to make usage
+ in other places easier (to avoid constant env lookup/parsing)
+
+ - struct bd_info and/or device tree
+ Note: these are temporary copies of the MAC address only for the
+ purpose of passing this information to an OS kernel we are about
+ to boot
+
+-------
+ Usage
+-------
+
+If the hardware design mandates that the MAC address is stored in some special
+place (like EEPROM etc...), then the board specific init code (such as the
+board-specific misc_init_r() function) is responsible for locating the MAC
+address(es) and initializing the respective environment variable(s) from it.
+Note that this shall be done if, and only if, the environment does not already
+contain these environment variables, i.e. existing variable definitions must
+not be overwritten.
+
+During runtime, the ethernet layer will use the environment variables to sync
+the MAC addresses to the ethernet structures. All ethernet driver code should
+then only use the enetaddr member of the eth_device structure. This is done
+on every network command, so the ethernet copies will stay in sync.
+
+Any other code that wishes to access the MAC address should query the
+environment directly. The helper functions documented below should make
+working with this storage much smoother.
+
+---------
+ Helpers
+---------
+
+To assist in the management of these layers, a few helper functions exist. You
+should use these rather than attempt to do any kind of parsing/manipulation
+yourself as many common errors have arisen in the past.
+
+ * void eth_parse_enetaddr(const char *addr, uchar *enetaddr);
+
+Convert a string representation of a MAC address to the binary version.
+char *addr = "00:11:22:33:44:55";
+uchar enetaddr[6];
+eth_parse_enetaddr(addr, enetaddr);
+/* enetaddr now equals { 0x00, 0x11, 0x22, 0x33, 0x44, 0x55 } */
+
+ * int eth_getenv_enetaddr(char *name, uchar *enetaddr);
+
+Look up an environment variable and convert the stored address. If the address
+is valid, then the function returns 1. Otherwise, the function returns 0. In
+all cases, the enetaddr memory is initialized. If the env var is not found,
+then it is set to all zeros. The common function is_valid_ether_addr() is used
+to determine address validity.
+uchar enetaddr[6];
+if (!eth_getenv_enetaddr("ethaddr", enetaddr)) {
+ /* "ethaddr" is not set in the environment */
+ ... try and setup "ethaddr" in the env ...
+}
+/* enetaddr is now set to the value stored in the ethaddr env var */
+
+ * int eth_setenv_enetaddr(char *name, const uchar *enetaddr);
+
+Store the MAC address into the named environment variable. The return value is
+the same as the setenv() function.
+uchar enetaddr[6] = { 0x00, 0x11, 0x22, 0x33, 0x44, 0x55 };
+eth_setenv_enetaddr("ethaddr", enetaddr);
+/* the "ethaddr" env var should now be set to "00:11:22:33:44:55" */
+
+ * the %pM format modifier
+
+The %pM format modifier can be used with any standard printf function to format
+the binary 6 byte array representation of a MAC address.
+uchar enetaddr[6] = { 0x00, 0x11, 0x22, 0x33, 0x44, 0x55 };
+printf("The MAC is %pM\n", enetaddr);
+
+char buf[20];
+sprintf(buf, "%pM", enetaddr);
+/* the buf variable is now set to "00:11:22:33:44:55" */

+ * This file implements UBIFS I/O subsystem which provides various I/O-related
+ * helper functions (reading/writing/checking/validating nodes) and implements
+ * write-buffering support. Write buffers help to save space which otherwise
+ * would have been wasted for padding to the nearest minimal I/O unit boundary.
+ * Instead, data first goes to the write-buffer and is flushed when the
+ * buffer is full or when it is not used for some time (by timer). This is
+ * similar to the mechanism is used by JFFS2.
+ *
+ * Write-buffers are defined by 'struct ubifs_wbuf' objects and protected by
+ * mutexes defined inside these objects. Since sometimes upper-level code
+ * has to lock the write-buffer (e.g. journal space reservation code), many
+ * functions related to write-buffers have "nolock" suffix which means that the
+ * caller has to lock the write-buffer before calling this function.
+ *
+ * UBIFS stores nodes at 64 bit-aligned addresses. If the node length is not
+ * aligned, UBIFS starts the next node from the aligned address, and the padded
+ * bytes may contain any rubbish. In other words, UBIFS does not put padding
+ * bytes in those small gaps. Common headers of nodes store real node lengths,
+ * not aligned lengths. Indexing nodes also store real lengths in branches.
+ *
+ * UBIFS uses padding when it pads to the next min. I/O unit. In this case it
+ * uses padding nodes or padding bytes, if the padding node does not fit.
+ *
+ * All UBIFS nodes are protected by CRC checksums and UBIFS checks all nodes
+ * every time they are read from the flash media.

+ * This file implements the LEB properties tree (LPT) area. The LPT area
+ * contains the LEB properties tree, a table of LPT area eraseblocks (ltab), and
+ * (for the "big" model) a table of saved LEB numbers (lsave). The LPT area sits
+ * between the log and the orphan area.
+ *
+ * The LPT area is like a miniature self-contained file system. It is required
+ * that it never runs out of space, is fast to access and update, and scales
+ * logarithmically. The LEB properties tree is implemented as a wandering tree
+ * much like the TNC, and the LPT area has its own garbage collection.
+ *
+ * The LPT has two slightly different forms called the "small model" and the
+ * "big model". The small model is used when the entire LEB properties table
+ * can be written into a single eraseblock. In that case, garbage collection
+ * consists of just writing the whole table, which therefore makes all other
+ * eraseblocks reusable. In the case of the big model, dirty eraseblocks are
+ * selected for garbage collection, which consists of marking the clean nodes in
+ * that LEB as dirty, and then only the dirty nodes are written out. Also, in
+ * the case of the big model, a table of LEB numbers is saved so that the entire
+ * LPT does not to be scanned looking for empty eraseblocks when UBIFS is first
+ * mounted.

+ * An orphan is an inode number whose inode node has been committed to the index
+ * with a link count of zero. That happens when an open file is deleted
+ * (unlinked) and then a commit is run. In the normal course of events the inode
+ * would be deleted when the file is closed. However in the case of an unclean
+ * unmount, orphans need to be accounted for. After an unclean unmount, the
+ * orphans' inodes must be deleted which means either scanning the entire index
+ * looking for them, or keeping a list on flash somewhere. This unit implements
+ * the latter approach.
+ *
+ * The orphan area is a fixed number of LEBs situated between the LPT area and
+ * the main area. The number of orphan area LEBs is specified when the file
+ * system is created. The minimum number is 1. The size of the orphan area
+ * should be so that it can hold the maximum number of orphans that are expected
+ * to ever exist at one time.
+ *
+ * The number of orphans that can fit in a LEB is:
+ *
+ * (c->leb_size - UBIFS_ORPH_NODE_SZ) / sizeof(__le64)
+ *
+ * For example: a 15872 byte LEB can fit 1980 orphans so 1 LEB may be enough.
+ *
+ * Orphans are accumulated in a rb-tree. When an inode's link count drops to
+ * zero, the inode number is added to the rb-tree. It is removed from the tree
+ * when the inode is deleted. Any new orphans that are in the orphan tree when
+ * the commit is run, are written to the orphan area in 1 or more orphan nodes.
+ * If the orphan area is full, it is consolidated to make space. There is
+ * always enough space because validation prevents the user from creating more
+ * than the maximum number of orphans allowed.

+ * return it.
+ *
+ * Note, this whole situation is possible because we allow to have

+ * splitting in the middle of the colliding sequence. Also, when
+ * removing the leftmost key, we would have to correct the key of the
+ * parent node, which would introduce additional complications. Namely,
+ * if we changed the the leftmost key of the parent znode, the garbage
+ * collector would be unable to find it (GC is doing this when GC'ing
+ * indexing LEBs). Although we already have an additional RB-tree where
+ * we save such changed znodes (see 'ins_clr_old_idx_znode()') until

+ * @ui_lock: protects @synced_i_size
+ * @synced_i_size: synchronized size of inode, i.e. the value of inode size

+ * @read_in_a_row: number of consecutive pages read in a row (for bulk read)
+ * @data_len: length of the data attached to the inode
+ * @data: inode's data
+ *
+ * @ui_mutex exists for two main reasons. At first it prevents inodes from
+ * being written back while UBIFS changing them, being in the middle of an VFS
+ * operation. This way UBIFS makes sure the inode fields are consistent. For
+ * example, in 'ubifs_rename()' we change 3 inodes simultaneously, and
+ * write-back must not write any of them before we have finished.
+ *
+ * The second reason is budgeting - UBIFS has to budget all operations. If an
+ * operation is going to mark an inode dirty, it has to allocate budget for
+ * this. It cannot just mark it dirty because there is no guarantee there will
+ * be enough flash space to write the inode back later. This means UBIFS has
+ * to have full control over inode "clean <-> dirty" transitions (and pages
+ * actually). But unfortunately, VFS marks inodes dirty in many places, and it
+ * does not ask the file-system if it is allowed to do so (there is a notifier,
+ * but it is not enough), i.e., there is no mechanism to synchronize with this.
+ * So UBIFS has its own inode dirty flag and its own mutex to serialize
+ * "clean <-> dirty" transitions.
+ *
+ * The @synced_i_size field is used to make sure we never write pages which are
+ * beyond last synchronized inode size. See 'ubifs_writepage()' for more
+ * information.
+ *
+ * The @ui_size is a "shadow" variable for @inode->i_size and UBIFS uses
+ * @ui_size instead of @inode->i_size. The reason for this is that UBIFS cannot
+ * make sure @inode->i_size is always changed under @ui_mutex, because it
+ * cannot call 'vmtruncate()' with @ui_mutex locked, because it would deadlock
+ * with 'ubifs_writepage()' (see file.c). All the other inode fields are
+ * changed under @ui_mutex, so they do not need "shadow" fields. Note, one
+ * could consider to rework locking and base it on "shadow" fields.
