Chuanxiao Dong 4e93b9a6ab mmc: card: Don't access RPMB partitions for normal read/write ... During kernel boot, it will try to read some logical sectors of each block device node for the possible partition table. But since RPMB partition is special and can not be accessed by normal eMMC read / write CMDs, it will cause below error messages during kernel boot: ... mmc0: Got data interrupt 0x00000002 even though no data operation was in progress. mmcblk0rpmb: error -110 transferring data, sector 0, nr 32, cmd response 0x900, card status 0xb00 mmcblk0rpmb: retrying using single block read mmcblk0rpmb: timed out sending r/w cmd command, card status 0x400900 mmcblk0rpmb: timed out sending r/w cmd command, card status 0x400900 mmcblk0rpmb: timed out sending r/w cmd command, card status 0x400900 mmcblk0rpmb: timed out sending r/w cmd command, card status 0x400900 mmcblk0rpmb: timed out sending r/w cmd command, card status 0x400900 mmcblk0rpmb: timed out sending r/w cmd command, card status 0x400900 end_request: I/O error, dev mmcblk0rpmb, sector 0 Buffer I/O error on device mmcblk0rpmb, logical block 0 end_request: I/O error, dev mmcblk0rpmb, sector 8 Buffer I/O error on device mmcblk0rpmb, logical block 1 end_request: I/O error, dev mmcblk0rpmb, sector 16 Buffer I/O error on device mmcblk0rpmb, logical block 2 end_request: I/O error, dev mmcblk0rpmb, sector 24 Buffer I/O error on device mmcblk0rpmb, logical block 3 ... This patch will discard the access request in eMMC queue if it is RPMB partition access request. By this way, it avoids trigger above error messages.
