How significant is the cache maintenance over head?

Per,

Can you measure how much difference this has before and after your
patch set please?

Absolutely, I can run the mmc_tests to get the measurement. The cache
affect is greater the faster the flash memory is. Currently I only
have access to a SD card (20 MiB/S). By the end of this week I can run
on eMMC (45 MiB/s) if this will be needed.

Thanks for your input,
Per
