Mike,
test case is [#6887], if you save data and read out to compare it sometimes fail. I agree that we can keep this patch, but it introduces problems to test engineer. This is a random error, she is difficult to know which board and which case we should enable this function.

BF5xx rx dma causes spi flash random read error. Accually spi controller has problems both on tx and rx dma. So remove spi dma support in u-boot.
this is wrong, and imo, unnecessary. it's wrong because using DMA gains a lot of speed increases, and works for in many cases (i haven't seen cases where it didn't work, but i haven't been actively developing in the last year of course). it's unnecessary because there's already a CONFIG_xxx option to disable it if your platform is having problems and you can't figure things out, and don't need the speed gains. -mike
