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!
I have no problem to build zynqmp on my PC. Can you please c&p error which you are getting?
I get this:
