2011-12-09arm: Move CP15 init out of cpu_init_crit()Simon Glass
Some SOCs have do not start up with their 'main' CPU. The first U-Boot code may then be executed with a CPU which does not have a CP15, or not a useful one. Here we split the initialization of CP15 into a separate call, which can be performed later if required. Once the main CPU is running, you should call cpu_init_cp15() to perform this init as early as possible. Existing ARMv7 boards which define CONFIG_SKIP_LOWLEVEL_INIT should not need to change, this CP15 init is still skipped in that case. The only impact for these boards is that the cpu_init_cp15() will be available even if it is never used on these boards.

2011-12-06MX: serial_mxc: cleanup removing nasty #ifdefStefano Babic
The serial driver for iMX SOCs is continuosly changed if a new SOC or not yet used port is used. CONFIG_SYS_<SOC>_<UART Port> defines were used only to find the base address for the selected UART. Instead of that, move the base address to the board configuration file and drop all #ifdef from driver.

This introduces 200MHz Micron parts timing information based on x-loader to <asm/arch-omap3/mem.h> and Numonyx MCFG calculation. The memory init logic is also based on what x-loader does in these cases. Note that while previously u-boot would be flashed in with SW ECC in this case it now must be flashed with HW ECC. We also change CONFIG_SYS_TEXT_BASE to 0x80100000.

2011-12-06OMAP3 SPL: Add identify_nand_chip functionTom Rini
A number of boards are populated with a PoP chip for both DDR and NAND memory. Other boards may simply use this as an easy way to identify board revs. So we provide a function that can be called early to reset the NAND chip and return the result of NAND_CMD_READID. All of this code is put into spl_id_nand.c and controlled via CONFIG_SPL_OMAP3_ID_NAND. Signed-off-by: Tom Rini <trini@ti.com>

2011-11-15omap4/5: Add support for booting with CH.Sricharan
Configuration header(CH) is 512 byte header attached to an OMAP boot image that will help ROM code to initialize clocks, SDRAM etc and copy U-Boot directly into SDRAM. CH can help us in by-passing SPL and directly boot U-boot, hence it's an alternative for SPL. However, we intend to support both CH and SPL for OMAP4/5. Initialization done through CH is limited and is not equivalent to that done by SPL. So U-Boot has to distinguish between the two cases and handle them accordingly. This patch takes care of doing this. Signed-off-by: sricharan <r.sricharan@ti.com> Signed-off-by: Sandeep Paulraj <s-paulraj@ti.com>
