From: Wang Huan Date: Fri, 5 Sep 2014 05:52:40 +0000 (+0800) Subject: ls102xa: esdhc: Add esdhc support for LS102xA X-Git-Tag: v2014.10-rc3~119^2~10 X-Git-Url: https://git.librecmc.org/?a=commitdiff_plain;h=19060bd886381a58cfe335c2f13b6111ed936dd5;p=oweals%2Fu-boot.git ls102xa: esdhc: Add esdhc support for LS102xA For LS1, esdhc is big-endian IP. Accessing the registers should be in big-endian mode. So we use esdhc_read32() to read Host controller capabilities register for LS1. For LS1, when using CMD12, cmdtype need to be set to ABORT, otherwise, next read command will hang.
