powerpc/virtex5: Fix Virtex5 machine check handling

2008-12-05T19:34:26+00:00

The 440x5 core in the Virtex5 uses the 440A type machine check
(ie, they have MCSRR0/MCSRR1). They thus need to call the
appropriate fixup function to hook the right variant of the
exception.

Without this, all machine checks become fatal due to loss
of context when entering the exception handler.

powerpc/44x: Fix 460EX/460GT machine check handling

powerpc: Remove use of CONFIG_PPC_MERGE

2008-08-04T03:18:17+00:00

Now that arch/ppc is gone and CONFIG_PPC_MERGE is always set, remove
the dead code associated with !CONFIG_PPC_MERGE from arch/powerpc
and include/asm-powerpc.

Revert "[POWERPC] 4xx: Fix 460GT support to not enable FPU"

2008-06-11T11:52:40+00:00

This reverts commit acb0142bf01c0ebe18f09e37814451ee6a873e27.

AMCC has indicated that the PPC 460GT does have FPU support.  This
revert enables the FPU for those chips again.

[POWERPC] 4xx: Fix 460GT support to not enable FPU

2008-04-24T18:32:47+00:00

The AMCC 460GT doesn't have an FPU so let's not enable support for it.

[POWERPC] 4xx: Add AMCC 460EX/460GT support to cputable.c & cpu_setup_44x.S

2008-03-26T12:19:16+00:00

This patch adds basic support for the AMCC 460EX/460GT PPC's to arch/powerpc.
Currently those PPC's are still based on a 440 core and *not* a 460 core.

Here some basic features of those SoC's:

460EX:
- Up to 1.2GHz, 32kB L1 I-cache and D-cache, 256kB L2-cache, FPU
- 1 * PCI (max 66MHz), 2 * PCIe (one 4-lane, one 1-lane)
- 2 * GBit Ethernet with TCP/IP acceleration
- USB 2.0 Host/Device OTG and Host interface
- SATA controller
- Optional security feature

460GT (only changes to 460EX):
- 4 * GBit Ethernet with TCP/IP acceleration
- RapidIO
- No SATA
- No USB

[POWERPC] 4xx: Fix 440grx setup function to call 440A fixup

2007-12-23T19:27:37+00:00

The mechanism to do the setup for 440A cores changed recently.  This fixes
the 440grx setup function to call __fixup_440A_mcheck.

[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.
