Dear sun york-R58495,
In message C707E9F4D8007146BF8DC1424B113AC70B3A435B@039-SN2MPN1-012.039d.mgd.msft.net you wrote:
Can we not split this into:
dcache flush icache invalidate
? This would make clear what's happening.
The idea is to reuse existing code with minimum addition. For the applicati ons concerned, these two steps are both needed. Splitting them doesn't make things easier.
Reusing code is a Good Thing, but not when it comes at the cost of obfucating what the code actually does.
If I have to use existing command, I'd rather to put these two steps under icache invalide <addr> <size>.
No, this is not acceptable. The "icache" command deals with the IC only, it must not meddle with the data cache (like flushing it).
Best regards,
Wolfgang Denk
