[U-Boot] [PATCH 0/4] zynq: fix OF control of Zynq

[Masahiro Yamada]

Zynq SoCs define CONFIG_OF_CONTROL and CONFIG_OF_SEPARATE,
but it is not working.

One possible workaround was to edit include/configs/zynq-common.h
to disable
  CONFIG_OF_CONTROL
  CONFIG_OF_SEPARATE
  CONFIG_DISPLAY_BOARDINFO_LATE
  CONFIG_FIT_SIGNATURE
  CONFIG_RSA

I am not satisfied with this temporal workaround.

My motivation is to run U-boot mainline on Zynq boards
with OF control.

To achieve this, SPL must load u-boot-dtb.bin.

1/4 adds support u-boot-dtb.img (= uImage header + u-boot-dtb.bin)

2/4 switches to load u-boot-dtb.img.

3/4 and 4/4 add missing some nodes to device tree.

This series was tested on my ZC706 board.



Masahiro Yamada (4):
  build: support a new image u-boot-dtb.img
  zynq: load u-boot-dtb.img for SD boot
  zynq: add memory nodes to device tree to initialize DRAM with OF
  zynq: add UART nodes to device tree to initialize UART with OF
