This patch series consists of a bunch of cleanups that allow us to use a common initdram() on all of the non-corenet 85xx-based boards. Also, switch to using phys_size_t to represent the size of memory returned.
Most of these patches are just code rearranges or renaming things to get a common scheme in place. There are also lots of cleanups - the various initdram() implementations had a variety of issues that I have hopefully fixed.
This is a large patch series, and I've had to hack on a bunch of different boards that I know nothing about, so I'd appreciate any review commentary. I have tested this on 8572DS and confirmed that the results of a MAKEALL powerpc are the same before and after this series.
Changes from V1: - Removed prints from initdram() as suggested by Peter - Changed spacing of 36-bit DRAM size warning messages to better line up after the removal of the excess prints from initdram() - Switched sdram_init() to be a weak function - renamed sdram_init() to lbc_sdram_init()
Changes from V2: - dropped boards that Kumar is removing - changed spacing of printouts from lbc_sdram_init - added the "DDR:" back to the boot messages - it makes sense to have this for some boards, and it's not much clutter - renamed the DDR_WIMGE define per feedback
Diffstat below.
Cheers, Becly
