Re: [PATCH] arm: kirkwood: Enable uart0 dm-pre-reloc for Kirkwood boards

Hi Tony,

When DM_SERIAL is enabled, the device-tree property dm-pre-reloc is required to boot over UART with kwboot. Enable this in a Kirkwood common u-boot dtsi.

My (dev) board unfortunately, have a bootloader which can't boot over serial. Could you elaborate that a bit more? Why is this required for uart boot? kwboot will talk with the bootrom why does u-boot need anything? Or will there just be no output until the uart is initialized?

Is this new? AFAIK only <boardname>-u-boot.dtsi is included automatically.
