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 Changelogs - V2 . fix styles and typos in [1/2] and [2/2] . add board documentation in [2/2] - V3 . fix styles in [1/2] - V4 . fix checkpatch warnings in [1/2] except MAINTAINERS - V5 . major changes in device tree . changed to OF_SEPARATE . formatting update for mmc - V6 . eliminate debug outputs altogether . separate defconfigs between SPL and u-boot proper . style updates thanks to Sean - V6 Resend . fix a few typos Acknowledgements We'd like to thank all maintainers who have reviewed our code. But we'd like to thank Sean in particular for taking much time and energy to help us write better code.
