5 This README is about U-Boot support for TI's ARM Cortex-A8 based OMAP3 [1]
6 family of SoCs. TI's OMAP3 SoC family contains an ARM Cortex-A8. Additionally,
7 some family members contain a TMS320C64x+ DSP and/or an Imagination SGX 2D/3D
8 graphics processor and various other standard peripherals.
10 Currently the following boards are supported:
12 * OMAP3530 BeagleBoard [2]
18 * OpenPandora Ltd. Pandora [5]
20 * TI/Logic PD Zoom MDK [6]
22 * TI/Logic PD Zoom 2 [7]
27 While ARM Cortex-A8 support ARM v7 instruction set (-march=armv7a) we compile
28 with -march=armv5 to allow more compilers to work. For U-Boot code this has
29 no performance impact.
36 make omap3_beagle_config
41 make omap3_overo_config
51 make omap3_pandora_config
56 make omap3_zoom1_config
61 make omap3_zoom2_config
67 To make U-Boot for OMAP3 support NAND device SW or HW ECC calculation, U-Boot
68 for OMAP3 supports custom user command
72 To be compatible with NAND drivers using SW ECC (e.g. kernel code)
76 enables SW ECC calculation. HW ECC enabled with
80 is typically used to write 2nd stage bootloader (known as 'x-loader') which is
81 executed by OMAP3's boot rom and therefore has to be written with HW ECC.
83 For all other commands see
90 OMAP3 U-Boot is based on U-Boot tar ball [8] for BeagleBoard and EVM done by
