X-Git-Tag: v3.15-rc1~12^2~9
X-Git-Url: http://git.openpandora.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=395ccb2531021974d309f26e5fb08a8240ac5f84;p=pandora-kernel.git

target/sbc: Add sbc_dif_read_strip software emulation

Split up __sbc_dif_verify_read() so that VERIFY READ emulation can
perform target-core specific READ_STRIP, seperate from the existing
FILEIO/RAMDISK backend emulation code.

Also add sbc_dif_read_strip() in order to determine number of sectors
using cmd->prot_length, and skip the extra sbc_dif_copy_prot().
