2Summary
3=======
4
5This README is about U-Boot support for TI's ARM Cortex-A8 based OMAP3 [1]
6family of SoCs. TI's OMAP3 SoC family contains an ARM Cortex-A8. Additionally,
7some family members contain a TMS320C64x+ DSP and/or an Imagination SGX 2D/3D
8graphics processor and various other standard peripherals.

10Currently the following boards are supported:
11
12* OMAP3530 BeagleBoard [2]
13
Dirk Behme9d0fc812009-01-28 21:39:57 +010014* Gumstix Overo [3]
15
Dirk Behmead9bc8e2009-01-28 21:39:58 +010016* TI EVM [4]
17
Dirk Behme2be2c6c2009-01-28 21:39:58 +010018* OpenPandora Ltd. Pandora [5]
19
Dirk Behme7379f452009-01-28 21:40:16 +010020* TI/Logic PD Zoom MDK [6]

25=========
26
27While ARM Cortex-A8 support ARM v7 instruction set (-march=armv7a) we compile
28with -march=armv5 to allow more compilers to work. For U-Boot code this has
29no performance impact.

Dirk Behmef904cdb2009-01-27 18:19:12 +010064Custom commands
65===============
66
67To make U-Boot for OMAP3 support NAND device SW or HW ECC calculation, U-Boot
68for OMAP3 supports custom user command
69
70nandecc hw/sw
71
72To be compatible with NAND drivers using SW ECC (e.g. kernel code)
73
74nandecc sw
75
76enables SW ECC calculation. HW ECC enabled with
77
78nandecc hw
79
80is typically used to write 2nd stage bootloader (known as 'x-loader') which is
81executed by OMAP3's boot rom and therefore has to be written with HW ECC.
