Subject: [U-Boot] [PATCH] PXAMMC: Drop different delays for PXA27X
Date: Mon, 5 Apr 2010 02:32:50 +0200 [thread overview]
Message-ID: <1270427570-29948-1-git-send-email-marek.vasut@gmail.com> (raw)
In case the delays were set to 10000, the MMC card on PXA27X boards (and PXA3xx
boards) didn't initialize on first try. Increasing the delays and leaving just
those for PXA25x and 26x (that is 200000) fixes this problem.
