Subject: mmc: show the erase group size and HC WP group size in mmcinfo output
X-Git-Tag: v2025.01-rc5-pxa1908~13890^2~9
X-Git-Url: http://git.dujemihanovic.xyz/html/static/gitweb.css?a=commitdiff_plain;h=b0361526d5dc3b09d16fbb8f36fbf999cc064640;p=u-boot.git

mmc: show the erase group size and HC WP group size in mmcinfo output

This adds the erase group size and high-capacity WP group size to
mmcinfo's output. The erase group size is necessary to properly align
erase requests on eMMC. The high-capacity WP group size is necessary
to properly align partitions on eMMC.
