To: u-boot
From: Carlo Caione <carlo@caione.org>
This driver implements MMC support on Meson GX (S905) based systems.
It's based on Carlo Caione's work, changes:
- BLK support added
- general refactoring

v6:
- remove DM_MMC_OPS from Kconfig dependencies
- address two minor review comments of Jaehoon

Sorry for bothering you..if you send the patches, i will apply yours immediately.
