Hi Mark,

The address of the debug UART varies differs between the M1 and the M1 Pro/Max SoCs. So we have to disable it to make a single U-Boot binary that works on all SoC generations. Leave the settings for the base address and clock rate of the M1 in place to make it easier to re-enable the debug UART when needed.
How about adding some docs about how to, and what the addresses are?
Yes I can do that. A section at the end of doc/board/apple/m1.rst?
Just list the relevant settings like in
doc/board/sipeed/maix.rst:591 doc/board/emulation/qemu-arm.rst:118
Is it ok if I provide a single update to that file for the M1 Pro/Max support?
Sounds right, just enough to explain how to enable it.

Please, use 'make savedefconfig' to create a consistent defconfig, and copy the generated defconfig to configs/apple_m1_defconfig before resubmitting.
