+
+The Nomadik 8815 CPU has a "secure" boot mode where no external access
+(not even JTAG) is allowed.  The "remap" bits in the evaluation board
+are configured in order to boot from the internal ROM memory (in
+secure mode).
+
+The boot process as defined by the manufacturer executes external code
+(loaded from NAND or OneNAND) that that disables such "security" in
+order to run u-boot and later the kernel without constraints. Such
+code is a proprietary initial boot loader, called "X-Loader" (in case
+anyone wonders, it has no relations with other loaders with the same
+name and there is no GPL code inside the ST X-Loader).
+
+SDRAM configuration, PLL setup and initial loading from NAND is
+implemented in the X-Loader, so U-Boot is already running in SDRAM
+when control is handed over to it.
+
+
+On www.st.com/nomadik and on www.stnwireless.com there are documents,
+summary data and white papers on Nomadik. The full datasheet for
+STn8815 is not currently available on line but under specific request
+to the local ST sales offices.

+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. Additionally,
+some family members contain a TMS320C64x+ DSP and/or an Imagination SGX 2D/3D
+graphics processor and various other standard peripherals.
+
+Currently the following boards are supported:
+
+* OMAP3530 BeagleBoard [2]
+
+* Gumstix Overo [3]
+
+* TI EVM [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
+=====
+
+* BeagleBoard:
+
+make omap3_beagle_config
+make
+
+* Gumstix Overo:
+
+make omap3_overo_config
+make
+
+* TI EVM:
+
+make omap3_evm_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

+several TI employees.
