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.

I am happy to take this series via zynq ARM tree. Or do you want to take fdt part through your tree or all things via your tree?
Thanks, Michal
