powerpc: Remove platforms/wsp and associated pieces

2014-06-11T06:35:38+00:00

__attribute__ ((unused)) WSP is the last user of CONFIG_PPC_A2, so we remove that as well. Although CONFIG_PPC_ICSWX still exists, it's no longer selectable for any Book3E platform, so we can remove the code in mmu-book3e.h that depended on it.

powerpc: Enforce usage of RA 0-R31 where possible

2012-07-10T09:18:35+00:00

Some macros use RA where when RA=R0 the values is 0, so make this the enforced mnemonic in the macro. Idea suggested by Andreas Schwab. Signed-off-by: Michael Neuling Signed-off-by: Benjamin Herrenschmidt

powerpc: Fix usage of register macros getting ready for %r0 change

2012-07-10T09:17:55+00:00

Anything that uses a constructed instruction (ie. from ppc-opcode.h), need to use the new R0 macro, as %r0 is not going to work. Also convert usages of macros where we are just determining an offset (usually for a load/store), like: std r14,STK_REG(r14)(r1) Can't use STK_REG(r14) as %r14 doesn't work in the STK_REG macro since it's just calculating an offset.

powerpc/book3e: Add ICSWX/ACOP support to Book3e cores like A2

2011-11-25T03:11:28+00:00

ICSWX is also used by the A2 processor to access coprocessors, although not all "chips" that contain A2s have coprocessors. Signed-off-by: Jimi Xenidis Signed-off-by: Benjamin Herrenschmidt

powerpc: Add A2 cpu support

2011-04-27T03:02:02+00:00

Add the cputable entry, regs and setup & restore entries for the PowerPC A2 core. Signed-off-by: Benjamin Herrenschmidt Signed-off-by: Michael Ellerman Signed-off-by: Benjamin Herrenschmidt
