This directory contains a port of the Linux SUNXI-MMC driver for
SD/MMC controllers.


Limitiations
~~~~~~~~~~~~

The eMMC module in the PinePhone is not initialized properly and
therefor is not usable. Furthermore SD card detection is not supported.


Usage
~~~~~

The driver will announce the 'Block' service for each successfully
initialized card.

To start the driver the following configuration snippet can be used:

! start a64_sd_card | caps: 500 | ram: 16M
! + provides
!   + service Block
! + config
!   + default-policy | device: mmcblk0 | writeable: no
! -


Additionally there exists the 'dtb' attribute in the 'config' node
that may be used to specify the name of the DTB ROM module, e.g.:

! config | dtb: sd_card-pinephone.dtb
! -
