Subject: [PATCH v8 02/11] ata: zpodd: Add CONFIG_SATA_ZPODD
Date: Mon, 29 Oct 2012 17:01:29 +0800 [thread overview]
Message-ID: <1351501298-3716-3-git-send-email-aaron.lu@intel.com> (raw)
In-Reply-To: <1351501298-3716-1-git-send-email-aaron.lu@intel.com>
Added a new config CONFIG_SATA_ZPODD, which is ued to support
SATA based zero power ODD. It depends on ACPI, and selects BLK_DEV_SR
as the implementation of ZPODD depends on SCSI sr driver.
2 new files are added, which will be used to host ZPODD related code.
They are empty for this commit.
