Zynq boards 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.
1/5 adds support u-boot-dtb.img (= uImage header + u-boot-dtb.bin)
2/5 switches to load u-boot-dtb.img.
3/5 thru 5/5 add missing some nodes to device tree.
This series was tested on my ZC706 board.
Changes in v2: - Select either "u-boot-dtb.img" or "u-boot.img" for CONFIG_SPL_FAT_LOAD_PAYLOAD_NAME. - Import zynq-7000.dtsi from Linux Kernel v3.15-rc5
Masahiro Yamada (5): build: support a new image u-boot-dtb.img zynq: load u-boot-dtb.img if CONFIG_OF_SEPARATE is defined zynq: import zynq-7000.dtsi from Linux Kernel zynq: add memory nodes to device tree to initialize DRAM with OF zynq: add UART nodes to device tree to initialize UART with OF
