Subject: mmc: don't read the size of eMMC enhanced user data area in SPL
X-Git-Tag: v2018.03-rc1~192^2~3
X-Git-Url: https://git.librecmc.org/?a=commitdiff_plain;h=173c06dfcc5419e38160d7eaf596256df0b4bdd5;p=oweals%2Fu-boot.git

mmc: don't read the size of eMMC enhanced user data area in SPL

This information is only used by the "mmc info" command.
On ARM removing this information from SPL saves about 140 of code space.
