>>
>> With D-cache and MMU enabled for ARM in u-boot it becomes imperative to
>> support a minimal set of cache maintenance operations and necessary
>> initializations before enabling MMU.
>>
>> This series of patches attempt to do the following for armv7:
>> * Necessary initialization sequence before enabling MMU that includes
>> invalidation of TLB, data caches, branch predictor array etc.
>> * Framework for supporting SOC specific outer caches in a generic manner
>> (using a structure of function pointers - inspired by the Linux
>> implementation)
>> * Generic armv7 cache maintenance operations for caches known to the CPU
>> * Support for ARM PL310 L2 cache controller used in OMAP4
>> * Cleanup of the cleanup_before_linux() function
>> * Adapting all armv7 SOCs to use the new framework and removing
>> duplicated code
>>
>> Testing:
>> * Extensive testing on OMAP4430SDP and OMAP3430SDP by creating coherency
>> issues and solving them using the maintenance routines
>> - Eg: memfill a region of memory with a known pattern
>> - Invalidate the region
>> - Read back and compare the region with the original pattern
>> - If match fails it means that invalidate is successful
>> - Now add a flush call just before the invalidate
>> - If match succeeds it means that flush was successful
>> - Outer caches were tested with experiments involving making the
>> function pointers NULL
>> * Kernel booting on OMAP4430SDP and OMAP3430SDP
>>
>>
>> Aneesh V (8):
>> arm: make default implementation of cache_flush() weakly linked
>> armv7: cache maintenance operations for armv7
>> armv7: integrate cache maintenance support
>> arm: minor fixes for cache and mmu handling
>> armv7: add PL310 support to u-boot
>> armv7: adapt omap4 to the new cache maintenance framework
>> armv7: adapt omap3 to the new cache maintenance framework
>> armv7: adapt s5pc1xx to the new cache maintenance framework

Hi Sandeep,

I have assigned these to me in patchwork but feel free to reclaim them
if you prefer.

Amicalement,
