I got D7b, which I was told it fixed it, but testing it, it did not
solve my problems.

Debian kernel does not build ACPI on arm64... I have recently pushed a
change for that that sets
CONFIG_ACPI=y on arm64.

However, there is still one more issue when relocating initramfs and that needs
CONFIG_ARM64_VA_BITS_48=y
but I am told that breaks userland, so it might need to be reverted.

Build a kernel with ACPI and VA_BITS_48 enabled, build d-i mini.iso
with that kernel. Boot device passing:
console=115200n8,ttyS0 earlycon acpi=force.
Yes, other distros kernel seem to work, at least I am told there
should be no issues with CentOS (using ACPI). I have not tried Ubuntu,
but using their kernel might be fastest way to install the board.
