Re: [U-Boot] [PATCH 1/3 v2] 83xx: Default to using DMA to initialize SDRAM

Dear Peter Tyser,

In message 1247582520.30723.4.camel@localhost.localdomain you wrote:

There was some discussion about whether to use DMA to initialize SDRAM on the 83xx architecture (which this patch does). After some benchmarking by Ira Synder it turns out that using DMA is actually slower than using the initial method of a series of 64-bit writes. Thus I'm assuming Kim would prefer not to use DMA and thus this patch should be discarded.

Kim, let me know if this is the case and I'll resubmit a patch just to fix the build error. Patches 2 and 3 are still applicable even if we discard patch 1.

We need at least the include/asm-ppc/config.h changes as these fix a real build problem.

Best regards,

Wolfgang Denk
