bcopyxx: when going to 16-bit PM, might as well do it right
When entering 16-bit PM after shuffle and boot, we might as well do so sanely. Specifically, set up the data segments so that they match the code segment, generating a 16-bit "tiny" model environment. This makes it a lot saner to bootstrap a proper PM environment from there if that is what the user intends. For the presumably more common case of RM entry, it won't do any harm, and it's only a handful of additional instructions. Signed-off-by: H. Peter Anvin <hpa@linux.intel.com>
