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 resyncs to u-boot.git master d8bec60c1b0de7770f9b56ad092ab9be801d99af as some recent mmc changes conflicted with these patches, in particular the DDR mode support.
