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

Dear Aneesh V,

How much of this is actually needed in the context of U-Boot?

Please see above. As far as I know OMAP doesn't do DMA in U-Boot.

Devices like USB oth Ethernet don't use DMA for data transfers?

Please do not add dead code. I consider it misleading to have functions which promise to perform something, and actually do nothing.

These are empty only in the else part of an #ifdef. When cache support is compiled out these need to be empty.

When cache support is compiled out there should be no callers to these functions, so maybe they can disappear?

Best regards,
