[PATCH] cfi_cmdset_0001: fix range for cache invalidation
I found an issue in cfi_cmdset0001.c. It is related to cache region
invalidation in the buffered write procedure.
The code performs cache invalidation from "cmd_addr" to "cmd_adr + len" in
do_write_buffer() while we modify region from "adr" to "adr+len".
This issue affects writes + reads of data by small chunks.
