I have the need to hardware partition eMMC devices from U-Boot along with setting enhanced and reliable write attributes.
This series of patches adds this support to U-Boot via a new mmc API, a few new members of struct mmc and a new mmc sub-command. It also features several fixes to the eMMC hardware partition support. I have tested this with Micron eMMC 4.41 parts and it is working as expected. This version updates the original patch series by reorganizing patches 14, 15 and 16 to make them cleaner, as requested by Pantelis. There are no functional changes. The patch series is against u-boot.git master of a few minutes ago.
