Hi Simon, why did you send this to the Tegra ML? Am Dienstag, den 11.08.2015, 08:25 -0600 schrieb Simon Glass:

This updates the device tree from the kernel version to something suitable for U-Boot: - Add stdout-path alias for console - Mark the /soc node to be available pre-relocation so that the early serial console works (we need the 'ranges' property to be available) Signed-off-by: Simon Glass <sjg@chromium.org> --- arch/arm/boot/dts/bcm2835.dtsi | 4 +++- 1 file changed, 3 insertions(+), 1 deletion(-)diff --git a/arch/arm/boot/dts/bcm2835.dtsi b/arch/arm/boot/dts/bcm2835.dtsi index 301c73f..bd6bff6 100644 --- a/arch/arm/boot/dts/bcm2835.dtsi +++ b/arch/arm/boot/dts/bcm2835.dtsi@@ -8,6 +8,7 @@ chosen { bootargs = "earlyprintk console=ttyAMA0"; + stdout-path = &uart; }; soc {@@ -16,6 +17,7 @@ #size-cells = <1>; ranges = <0x7e000000 0x20000000 0x02000000>; dma-ranges = <0x40000000 0x00000000 0x20000000>; + u-boot,dm-pre-reloc;
Why do you need this and why should upstream carry your favourite bootloaders configuration? This is in no way hardware description. Regards, Lucas
