Hey all,
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 v3: - Rename CONFIG_SPL_OMAP3_POP_PROBE to CONFIG_SPL_OMAP3_ID_NAND at Igor's request (and function to identify_nand_chip). - Drop an unused CONFIG_OMAP3_MICRON_DDR from all of the board config files
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.
