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.

Changes in v5: Patches were tested with Andreas's system firmware patches[1] but can now be independently merged cleanly on latest U-boot.

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

New subject: [U-Boot] [PATCH v5 01/15] arm64: dts: k3: Sync sdhci0 node from kernel and change driver name

Sync the sdhci0 node from kernel. This changes the compatible that is required to be there in the driver. Change the same for the SD card node which is not yet supported in kernel. This also syncs the main_pmx0 node as a side effect.

Also change the name of the driver to match the compatible in kernel.

Sync the sdhci0 node from kernel. This changes the compatible that is required to be there in the driver. Change the same for the SD card node which is not yet supported in kernel. This also syncs the main_pmx0 node as a side effect.

Also change the name of the driver to match the compatible in kernel.
