[PATCH 0/6] mmc: fsl_esdhc: add ADMA2 support

[Michael Walle]

Add ADMA2 support mainly because it supports 64bit DMA addresses. These are
for example used if you use EFI on a LS1028A board which has more than 2GB
of RAM, because only the lower 2GB are mapped into the lower 32bit address
space.

Patches 1-4 clean the fsl_esdhc driver up. Patch 5 moves ADMA2 table
handling code out of the sdhci core code. Patch 6 finally adds the ADMA2
support to the fsl_esdhc driver.

This was tested on a custom board LS1028A board.

A passing travis-ci build is available at:
