Hi everyone,

This patchset is v3 of a spin-off from original i.MX7 support submission
found here [1], containing all of the patchest that are more or less
agreed upon and are ready (hopefully!) for inclusion.

Changes since [v2]:

        - All SD related patches are dropped from this series (to be
          re-submitted once Philippe's work lands upstream). Note that
          "Implement write method of ACMD12ERRSTS register" has been
          incorporated into Philippe's submission

        - Collected Reviewed-by for patch 2 from Philippe

Changes since [v1]:

        - Collected Reviewed-by tags from Peter

        - Implemented forgotten feedback from Peter for
          "sdhci: Add i.MX specific subtype of SDHCI"

        - "imx_fec: Move Tx frame buffer away from the stack" sent out
          properly (fingers crossed)

        - Added trivial patch to swith i.MX6 over to TYPE_IMX_USDHC

        - Added "sd: Check for READ_MULTIPLE_BLOCK size limit
          violation first" to address a small problem I was seeing
          when tesiting SD against latest vanilla kernel

Changes since [1]:

        - Rx buffer in FEC was moved from stack to heap to allow
          worry-free expansion to 16K limit.

        - Added more comments explaining rather convoluted bit-moving
          in eSHDC emuation code

        - Triple Tx ring DMA "VMState" code was changed to follow
          Peter's recommendations (avoiding the need to incrememnt the

        - FSL_IMX25_FEC_SIZE is used as a size of FEC's register file

        - Removed leftover code from "imx_fec: Change queue flushing
