[U-Boot] [PATCH v2 0/12] Add more framework to OMAP3 SPL, port more boards
This is related to, but a bit different from the RFT thread I made with beagleboard SPL patches. I've incorporated the feedback about splitting the changes up a lot more and after talking with Scott Wood on IRC after the ML thread, I've created an omap3 specific file with the NAND related stuff these boards need (since it would have gotten very big for what's really needed here at this stage). The series is checkpatch.pl clean.
What we have in patches 1-6 is bugfixing and cleanup of the SDRC code. It's worth noting that without these changes we do some very 'funny' (read: wrong) things on some platforms like omap3_evm where we find 384MB memory when there's really only 256MB (and maybe 256 on the 128MB boards, not sure).
Patch 7 adds another hook for SDRC boards to be able to say what timings they have because on say beagle or omap3_evm, we have a few choices. We also convert devkit8000 here.
Patch 8 adds a new CONFIG (CONFIG_SPL_OMAP3_POP_PROBE) and file so that OMAP3 boards which have a PoP chip for NAND/DDR can find out what they are and decide on timings based on that. While I can see in theory the case where one probes NAND to determine DDR timings and isn't actually populated with a PoP chip, I don't know if we have any of those in practice.
Patches 9 and 10 convert Beagleboard and OMAP3 EVM to SPL.
Patches 11 and 12 convert the am3517 evm and am3517 crane boards (which don't use SDRC but EMIF4) to SPL as well (given Ilya Yanok fixed a bug in <asm/arch-omap3/cpu.h for emif4 this is just a mechanical change).
Changes in v2: - Incorporate Igor Grinberg's feedback (except non-CodingStyle whitespacing). - Move to ToT (so omap3_evm patch is reworked a good deal, others that touch <asm/arch-omap3/mem.h> reworked and use new macros when applicable) - Fixed a few more typos and hardcoded values to defines while addressing Igor's feedback.
We update the comment in make_cs1_contiguous() to be a little bit more clear (it's been copy/pasted from other silicons) and then explain in dram_init() why we need to always try this.
Note that in the previous behavior we were always calling this on boards that never had cs1 populated anyhow so making sure we do this always is fine and will correct things like omap3evm detecting an invalid amount of memory (384MB).

Since we go through the sequence to setup the SDRC timings more than once, break this logic out into its own function and have that function call mem_ok() to make sure the memory is usable.

This adds the optimal SDRC autorefresh control register values for 100Mhz, 133MHz, 165MHz and 200MHz clocks. We switch to using this to provide the default 165MHz value.

A number of boards are populated with a PoP chip for both DDR and NAND memory. So to determine DDR timings the NAND chip needs to be probed and mfr/id returned to the board to make decisions with. All of this code is put into spl_pop_probe.c and controlled via CONFIG_SPL_OMAP3_POP_PROBE.

This introduces 200MHz Micron parts timing information based on x-loader to <asm/arch-omap3/mem.h>. 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.
