sparc32: implement proper LEON support in head_32 (before highmem)
Use PSR to check if the CPU is LEON and jump to LEON specific code in this case. Added a few constants to psr.h to increase readability. Signed-off-by: Sam Ravnborg <sam@ravnborg.org> Cc: Daniel Hellstrom <daniel@gaisler.com> Cc: Konrad Eisele <konrad@gaisler.com>
