 PCI:
 ====
 
-This board and U-Boot have been tested with PCI built in, on a SBC8349
-and confirmed that the "pci" command showed the intel e1000 that was
-present in the PCI slot.  Note that if a 33MHz 32bit card is inserted
-in the slot, then the whole board will clock down to a 33MHz base
-clock instead of the default 66MHz.  This will change the baud clocks
-and mess up your serial console output.  If you want to use a 33MHz PCI
-card, then you should build a U-Boot with #undef PCI_66M in the
-include/configs/sbc8349.h and store this to flash prior to powering down
-the board and inserting the 33MHz PCI card.
+There are three configuration choices:
+	sbc8349_config
+	sbc8349_PCI_33_config
+	sbc8349_PCI_66_config
 
-By default PCI support is disabled to better support very early
-revision MPC834x chips with possible PCI issues.  Also PCI support is
-untested on the sbc8347 variants at this point in time.
+The 1st does not enable CONFIG_PCI, and assumes that the PCI slot
+will be left empty (M66EN high), and so the board will operate with
+a base clock of 66MHz.  Note that you need both PCI enabled in u-boot
+and linux in order to have functional PCI under linux.  The only
+reason for choosing to not enable PCI would be if you had a very
+early (rev 1.0) CPU with possible PCI issues.
 
+The second enables PCI support and builds for a 33MHz clock rate.  Note
+that if a 33MHz 32bit card is inserted in the slot, then the whole board
+will clock down to a 33MHz base clock instead of the default 66MHz.  This
+will change the baud clocks and mess up your serial console output if you
+were previously running at 66MHz.  If you want to use a 33MHz PCI card,
+then you should build a U-Boot with sbc8349_PCI_33_config and store this
+to flash prior to powering down the board and inserting the 33MHz PCI
+card.
 
-						Paul Gortmaker, 01/2007
+The third option builds PCI support in, and leaves the clocking at the
+default 66MHz.  This has been tested with an intel PCI-X e1000 card.
+This is also the appropriate choice for people with a recent (non 1.0)
+CPU who currently have the PCI slot physically empty, but intend to
+possibly add a PCI-X card at a later date.
