This patch set is to add OpenPiton board support. Patches are split into several parts:
- [PATCH 1/2] add OpenPiton support to mmc driver - [PATCH 2/2] add support for OpenPiton board
Description
- for mmc driver, it's settings are automatically configured at hardware level. We only need to expose the memory mapped interface through U-Boot driver model - For OpenPiton, as we need to embed the device tree blob into the bitstream, there is currently no itb support
Tests checks
- Able to boot Debian Linux from SD card on Digilent Genesys 2 - Checkpatch is performed, with some warnings ignored
