Currently we support only one memory bank for dom0 when the 1:1 mapping
is enabled. This solution is not reliable because it will depends where
U-boot has loaded modules (kernel, initramfs, dtb,...) in the RAM.
The proper solution would be to support multiple banks for dom0. When
Xen will allocate dom0 memory, it will split the total amount of RAM in
small chunk, so it will likely be able to allocate the memory correctly,
even with the 1:1 mapping.
Sincerely yours,
