+Summary
+=======
+
+This README is about U-Boot support for TI's ARM Cortex-A8 based OMAP3 [1]
+family of SoCs. TI's OMAP3 SoC family contains an ARM Cortex-A8 core running
+at ~600MHz. Additionally some family members contain a TMS320C64x+ DSP ~430MHz
+and/or an Imagination SGX 2D/3D graphics processor and various other standard
+peripherals.
+
+Currently the following boards are supported:
+
+* TI EVM [2]
+
+* Gumstix Overo [3]
+
+* TI/DigiKey BeagleBoard [4]
+
+* OpenPandora Ltd. Pandora [5]
+
+* TI/Logic PD Zoom MDK [6]
+
+Toolchain
+=========
+
+While ARM Cortex-A8 support ARM v7 instruction set (-march=armv7a) we compile
+with -march=armv5 to allow more compilers to work. For U-Boot code this has
+no performance impact.
+
+Build
+=====
+
+* TI EVM:
+
+make omap3_evm_config
+make
+
+* Gumstix Overo:
+
+make omap3_overo_config
+make
+
+* BeagleBoard:
+
+make omap3_beagle_config
+make
+
+* Pandora:
+
+make omap3_pandora_config
+make
+
+* Zoom MDK:
+
+make omap3_zoom1_config
+make
+
+Custom commands
+===============
+
+To make U-Boot for OMAP3 support NAND device SW or HW ECC calculation, U-Boot
+for OMAP3 supports custom user command
+
+nandecc hw/sw
+
+To be compatible with NAND drivers using SW ECC (e.g. kernel code)
+
+nandecc sw
+
+enables SW ECC calculation. HW ECC enabled with
+
+nandecc hw
+
+is typically used to write 2nd stage bootloader (known as 'x-loader') which is
+executed by OMAP3's boot rom and therefore has to be written with HW ECC.
+
+For all other commands see
+
+help
+
+Acknowledgements

+
+OMAP3 U-Boot is based on U-Boot tar ball [7] for BeagleBoard and EVM done by
+several TI employees.
