[U-Boot] [PATCH v3 0/6] board: sama5d3: convert boards to support DM/DT

[U-Boot] [PATCH v3 0/6] board: sama5d3: convert boards to support DM/DT

[Wenyou Yang]

The purpose of patch set is to convert the board to support device
tree and driver model, and enable the early debug UART as well.
It is based on the patch set:
	[PATCH v8 0/2] pinctrl: at91: Add pinctrl driver
	https://lists.denx.de/pipermail/u-boot/2017-March/284577.html

Changes in v3:
 - Convert the macb to support DM and clean up macb init code.
 - Remain the SPI speed macros.
 - Update the config options for SPL.
 - Update the commit log.
 - Remove the unneeded dbgu init during board_early_init_f stage.
 - Use CONFIG_DEBUG_UART_CLOCK as the input clock for the early
   debug uart.
 - Drop [PATCH] configs: sama5d3_xplained: move CONFIG_SYS_NO_FLASH
   to defconfig.
 - Rebase on v2017.03.

Changes in v2:
 - rebase on the patch set:
        [PATCH v3 0/8] board: sama5d4: convert boards to support DM/DT
        http://lists.denx.de/pipermail/u-boot/2017-February/280506.html

[U-Boot] [PATCH v3 1/6] board: sama5d3xek: update to support DM/DT

[Wenyou Yang]

Update the configuration files to support the device tree and
driver model, so do SPL. The device clock and pins configuration
are handled by the clock and the pinctrl drivers respectively.

[U-Boot] [PATCH v3 2/6] board: sama5d3xek: clean up code

[Wenyou Yang]

Due to the introduction of the pinctrl and clk driver, and using
device tree files, remove the unneeded hardcoded pin configuration
and clock enabling code from the board file.

[U-Boot] [PATCH v3 4/6] board: sama5d3_xplained: update to support DM/DT

[Wenyou Yang]

Update the configuration files to support the device tree and driver
model, so do SPL. The device clock and pins configuration are handled
by the clock and the pinctrl drivers respectively.

[U-Boot] [PATCH v3 5/6] board: sama5d3_xplained: clean up code

[Wenyou Yang]

Due to the introduction of the pinctrl and clk driver, and using
device tree files, remove the unneeded hardcoded pin configuration
and clock enabling code from the board file.

I was going to test these out on my SAMA5D31EK but it appears to be bricked as the only output I get at power-on is a single "RomBOOT" and SAM-BA doesn't seem to want to connect.

Is there any way I can de-brick the board so I can test these patches?

Thanks,

Andy.
