OK, there's a few problems here:

Please remove this (and audit the series for other) bring-up debug
printfs that we shouldn't need anymore.

Er, do you really need this?

CONFIG_MACH_TYPE is not relevant to aarch64 platforms (it's for
pre-device tree boards) and 'BIT(20)' isn't a valid value for
CONFIG_SYS_NONCACHED_MEMORY (and leads to a warning a build).

Thanks!
