apalis_t30: optional mmc uhs support (v1.1a and later hw)Colibri_T30_LinuxImageV2.3Beta5_20141219Colibri_T20_LinuxImageV2.3Beta5_20141219Apalis_T30_LinuxImageV2.3Beta5_20141219
This patch adds optional UHS support for the 8-bit MMC controller.
Please note that this requires V1.1A or later module hardware plus the
pull-up resistors on the data as well as the command signal lines of
your carrier board need to be removed (e.g. R46 to R54 on our Apalis
Evaluation Board V1.1A). If those pre-requisites are met support can be
enabled using the following kernel command line parameter:
mmc_uhs=1
