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.
I am new to sending patches to the U-Boot mailing list, let alone
working with git, so please excuse any mishaps.
Diego Santa Cruz (18):
mmc: show hardware partition sizes in mmcinfo output
mmc: extend mmcinfo to show enhanced partition attribute
mmc: make eMMC general purpose partition numbering match spec
mmc: skip mmcinfo partition info processing for eMMC < 4.41
mmc: incomplete test to switch to high-capacity group size
definitions
mmc: computation of eMMC GP partition size was missing 512 KiB factor
mmc: read the size of eMMC enhanced user data area
mmc: display size and start of eMMC enhanced user data area in
mmcinfo
mmc: fix erase_grp_size computation with high-capacity size
definition
mmc: read the high capacity WP group size for eMMC
mmc: show the erase group size and HC WP group size in mmcinfo output
mmc: eMMC partitioning data is not effective till partitioning
completed
mmc: the ext_csd data may be used during init even if reading failed
mmc: add API to do eMMC hardware partitioning
mmc: add mmc hwpartition sub-command to do eMMC hardware partitioning
mmc: extend the mmc hardware partitioning API with write reliability
mmc: extend the mmc hwpartition sub-command to change write
reliability
mmc: extend mmcinfo output to show partition write reliability
