Add Support for eMMC in TI's AM65x-evm. The series starts by syncing the sdhci0 node from the kernel. Then it adds APIs and changes to the driver required for handling the driver's integrated phy. The current maximum supported speed is DDR52. Higher speeds and tuning support will be added in a subsequent series.
Tested on top of Andreas's sysfw loader patches here: https://www.mail-archive.com/u-boot@lists.denx.de/msg325811.html
Changes in v4: 1. Dropped the patch including regmap_read_poll_timeout() because that support was already added by someone else 2. Fixed a NULL pointer exception in patch 8. 3. Rebased on top of latest master 4. Added extra patches to support GPT partitions in user partition 5. Added Support for environment in eMMC by default
Changes in v3: Patch 9: Got rid of variable ret
Changes in v2: Patch 9: Fixed return value Patch 12: Fixed spacing
