Subject: [PATCH] mpc8308rdb: add support for eSDHC MMC controller
Add support for the onboard eSDHC MMC controller. The hardware on the
MPC8308RDB has the following errata:
- ESDHC111: manual asynchronous CMD12 is broken
- DMA is broken (PIO works)
Signed-off-by: Ira W. Snyder <iws@ovro.caltech.edu>
[added include fsl_esdhc header to prevent implicit declarations of
fsl_esdhc_mmc_init() and fdt_fixup_esdhc()]
