>> This series of patches attempt to do the following for armv7:

>> * Framework for supporting SOC specific outer caches in a generic manner
>>    (using a structure of function pointers - inspired by the Linux

>> * 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

>> 	- Invalidate the region

>> 	- If match fails it means that invalidate is successful

Hi Sandeep,

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

Amicalement,
