Re: [U-Boot] [PATCH v3 03/10] armv7: cache maintenance operations for armv7

Hi, I am picking up on this old thread. My main point is that I think the armv7 cache implementation is a good start and should go into U-Boot. Aneesh are you planning another patch set? Also see below: On Tue, May 17, 2011 at 2:58 AM, Aneesh V wrote: > Hi Wolfgang, > > On Tuesday 17 May 2011 03

[U-Boot] [PATCH v3 03/10] armv7: cache maintenance operations for armv7

2011-05-12 Thread Aneesh V
- Add a framework for layered cache maintenance - separate out SOC specific outer cache maintenance from maintenance of caches known to CPU - Add generic ARMv7 cache maintenance operations that affect all caches known to ARMv7 CPUs. For instance in Cortex-A8 these opertions w
