[U-Boot] [PATCH v2 00/14] dm: arm: zynq: Convert serial driver to driver model

[Simon Glass]

This series updates the Zynq serial driver to use driver model. Along the
way several problems are fixed:

- Support for /chosen/stdout-path using an alias
- Fix to fdtgrep which is currently breaking alias building
- Avoid building u-boot-spl-dtb.bin when it is not requested
- Deal with boards which have BSS in SDRAM

For zynq this series makes a few changes:
- Use the new SPL init procedure, which just involves a few tweaks for zynq
- Add debug UART support
- Move to using a separate device tree instead of embedded

Only zybo has been tested. Testing on other zynq boards is welcome. They are
all set up roughly the same so I expect only minor problems.

This serial includes Michal's zynqmp device tree patch.

Changes in v2:
- Extend list of compatible strings with cadence compatible string.
