[U-Boot] [PATCH 00/13] dm: arm: zynq: Convert serial driver to driver model

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.

For some reason zynqmp does not have a device tree, so this series does not
work on that. But that board fails to build on mainline for me anyway so
perhaps nothing is lost. I don't have a board to test with so help on this
would be appreciated!

Simon Glass (13):
fdt: Add a function to look up a /chosen property
fdt: Correct handling of alias regions
fdtgrep: Simplify the alias generation code
dm: serial: Deal with stdout-path with an alias
dm: spl: Generate u-boot-spl-dtb.bin only when enabled
dm: spl: Support device tree when BSS is in a different section
arm: zynq: Use separate device tree instead of embedded
arm: zynq: Drop unnecessary code in SPL board_init_f()
arm: zynq: Support the debug UART
dm: arm: zynq: Enable device tree control in SPL
arm: zynq: dts: Add U-Boot device tree additions
arm: zynq: serial: Drop non-device-tree serial driver portions
arm: zynq: Move serial driver to driver model
