From 0f762426769a517d5b278e4e5d579fcea6801734 Mon Sep 17 00:00:00 2001 From: Gwendal Grignou Date: Thu, 16 Oct 2014 11:27:16 -0700 Subject: mmc: core: Report firmware version for eMMC 5.0 devices. For eMMC 5.0 compliant device, firmware version is stored in ext_csd. Report firmware as a 64bit hexa decimal. Vendor can use hexa or ascii string to report firmware version. Also add FFU related EXT_CSD register and note if the device is FFU capable.
