[Xen-devel] [PATCH v2 1/2] xen/arm: Extend the number of memory banks supported

When booting using Grub on Thunder-X, the number of memory available is
greater than 64. Bump the number to 128, so we can take advantage of all
the memory.

Signed-off-by: Julien Grall <julien.grall@xxxxxxx>


    Note that I wasn't able to boot without this patch, because EFI stub
    is printing an error when the number of region exceed 64. This will
    result to fragment in bit more the memory (sounds like print
    allocate memory) and will fail to get the memory on retry.
