Subject: [PATCH 4/4] [Target_Core_Mod]: Convert TYPE_ROM support to use include/linux/cdrom.h GPCMD_* defines
This patch updates transport_generic_cmd_sequencer() to use GPCMD_* MMC opcode defines
from include/linux/cdrom.h, instead of our locally defined ones w/o the GPCMD_* prefix
in drivers/lio-core/target_core_base.h. This patch removes all those locally defined
opcodes in target_core_base.h (some which date back to usage on v2.2), and adds
GPCMD_MECHANISM_STATUS and GPCMD_READ_FORMAT_CAPACITIES CDB support in the generic
cdb sequencer.
