> saving header in mrc_cache.

To clarify, mrc cache already contains the checksum so we don't need it in the header.

We should add

dparam->header.config |= DRAMC_CONFIG_FAST_K;

back, because now that the header is stored in mrc cache, it won't contain DRAMC_CONFIG_FAST_K (unless you want to set that before saving data to flash).

Add one blank line.
