Subject: sm501: fixup allocation code to be 64bit resource compliant
From: Ben Dooks <ben-linux@xxxxxxxxx>
As pointed out by Andrew Morton, we have a problem when setting the 64bit
resources option. Alter the allocation routines to remove the need to use
the start and end fields, use the proper HEAD_PANEL/HEAD_CRT and update
the comments.
Note, we also fix the bug where we failed to check the size of the
CRT memory allocation.
