[POWERPC} Add oprofile support for e300

2008-02-06T05:37:58+00:00

The e300 c3 and c4 variants support hardware performance monitor counters
which are identical to those found in the e500.

[POWERPC] Made FSL Book-E PMC support more generic

2008-02-06T05:34:14+00:00

Some of the more recent e300 cores have the same performance monitor
implementation as the e500.  e300 isn't book-e, so the name isn't
really appropriate.  In preparation for e300 support, rename a bunch
of fsl_booke things to say fsl_emb (Freescale Embedded Performance Monitors).

[POWERPC] 4xx: Add PowerPC 440EP Rev C

2008-01-25T13:08:27+00:00

This adds the 440EP revision C PVR to the CPU table.  The chip has an
FPU on it, so we also match the logical PVR

[POWERPC] 4xx: Add 405EXr to cputable

2008-01-25T13:06:09+00:00

This patch adds the 405EXr to the powerpc cuptable. Basically the 405EXr
is a 405EX with only one EMAC and only one PCIe interface.

[POWERPC] Conditionally compile e200 and e500 platforms in cputable

2007-12-24T14:44:47+00:00

The e200 and e500 platforms are separated in various parts of the kernel with
ifdefs, most notably reg_booke.h and traps.c.  The new machine_check rework
requires them to be similarly separated in cputable.c to avoid compile errors.

[POWERPC] Reworking machine check handling and Fix 440/440A

2007-12-23T19:11:59+00:00

This adds a cputable function pointer for the CPU-side machine
check handling. The semantic is still the same as the old one,
the one in ppc_md. overrides the one in cputable, though
ultimately we'll want to change that so the CPU gets first.

This removes CONFIG_440A which was a problem for multiplatform
kernels and instead fixes up the IVOR at runtime from a setup_cpu
function. The "A" version of the machine check also tweaks the
regs->trap value to differenciate the 2 versions at the C level.

[POWERPC] 4xx: Workaround for the 440EP(x)/GR(x) processors identical PVR issue.

2007-11-01T12:13:43+00:00

PowerPC 440EP(x) 440GR(x) processors have the same PVR values, since
they have identical cores. However, FPU is not supported on GR(x) and
enabling APU instruction broadcast in the CCR0 register (to enable FPU)
may cause unpredictable results. There's no safe way to detect FPU
support at runtime. This patch provides a workarund for the issue.

We use a POWER6 "logical PVR approach". First, we identify all EP(x)
and GR(x) processors as GR(x) ones (which is safe). Then we check
the device tree cpu path. If we have a EP(x) processor entry,
we call identify_cpu again with PVR | 0x8. This bit is always 0
in the real PVR. This way we enable FPU only for 440EP(x).
