Subject: [PATCH] powerpc/85xx: Make eSDHC 1-bit only transfer mode default for MPC8569E-MDS
Date: Fri, 19 Jun 2009 03:37:52 +0400	[thread overview]
Message-ID: <20090618233752.GA13279@oksana.dev.rtsoft.ru> (raw)

For yet unknown reason 4-bit mode doesn't work on MPC8569E-MDS boards,
so make 1-bit mode default. When we resolve the issue, u-boot will
remove sdhci,1-bit-only property from the device tree, while SDHCI
will still work with older u-boots.
