[POWERPC] Make xmon disassembly optional
While adding spu disassembly support it struck me that we're actually carrying quite a lot of code around, just to do disassembly in the case of a crash. While on large systems it's not an issue, on smaller ones it might be nice to have xmon - but without the weight of the disassembly support. For a Cell build this saves ~230KB (!), and for pSeries ~195KB. We still support the 'di' and 'sdi' commands, however they just dump the instruction in hex. Move the definitions into a header to clean xmon.c just a tiny bit. Signed-off-by: Michael Ellerman <michael@ellerman.id.au> Signed-off-by: Arnd Bergmann <arnd.bergmann@de.ibm.com>
