Move drivers/storage into commonlib/storage to enable access by libpayload and indirectly by payloads. * Remove SD/MMC specific include files from include/device * Remove files from drivers/storage * Add SD/MMC specific include files to commonlib/include * Add files to commonlib/storage * Fix header file references * Add subdir entry in commonlib/Makefile.inc to build the SD/MMC driver * Add Kconfig source for commonlib/storage * Rename *DEVICE* to *COMMONLIB* * Rename *DRIVERS_STORAGE* to *COMMONLIB_STORAGE* TEST=Build and run on Galileo Gen2 Change-Id: I4339e4378491db9a0da1f2dc34e1906a5ba31ad6 Signed-off-by: Lee Leahy <Leroy.P.Leahy@intel.com> Reviewed-on: https://review.coreboot.org/19672 Tested-by: build bot (Jenkins) <no-reply@coreboot.org> Reviewed-by: Patrick Georgi <pgeorgi@google.com>
