Presumably it makes sense for the cache to work for IDE, SATA, USB, SCSI, ... too. I wonder if it's possible to put this code somewhere more central than mmc*.c so it automatically applies to dev_desc->block_read() (see include/part.h). Perhaps not since each implementation supplies its own block_read function directly, so the cache calls do need to be duplicated everywhere.
Yeah. I haven't found a spot that would allow interception of the various block_read/write functions.
Shouldn't DM also help here?
