powerpc/book3e: Fix CPU feature handling on 64-bit e5500

2011-04-12T11:29:21+00:00

The CPU_FTRS_POSSIBLE and CPU_FTRS_ALWAYS defines did not encompass
e5500 CPU features when built for 64-bit.  This causes issues with
cpu_has_feature() as it utilizes the POSSIBLE & ALWAYS defines as part
of its check.

Create a unique CPU_FTRS_E5500 (as its different from CPU_FTRS_E500MC),
created a new group for 64-bit Book3e based CPUs and add CPU_FTRS_E5500
to that group.

powerpc: Pass the right cpu_spec to ->setup_cpu() on 64-bit

2011-02-07T01:47:57+00:00

When calling setup_cpu() on 64-bit, we pass a pointer to the
cputable entry we have found. This used to be fine when cur_cpu_spec
was a pointer to that entry, but nowadays, we copy the entry into
a separate variable, and we do so before we call the setup_cpu()
callback. That means that any attempt by that callback at patching
the CPU table entry (to adjust CPU features for example) will patch
the wrong table.

powerpc/476: define specific cpu table entry DD2 core

2011-02-02T11:58:53+00:00

The DD2 core still has some unstability.  Define CPU_FTR_476_DD2 to
enable workarounds in later patches.

This is based on an earlier, unreleased patch for DD1 by Ben Herrenschmidt.

powerpc: machine_check_generic is wrong on 64bit

2011-01-21T03:08:38+00:00

Decoding machine checks is CPU specific and so machine_check_generic doesn't
do the right thing on 64bit chips. Luckily we never call into this code
because we call ppc_md.machine_check_exception instead if available.

Since we check cur_cpu_spec->machine_check before calling it, we may as
well remove machine_check_generic from 64bit archs.

powerpc: Add POWER7+ cputable entry

2010-11-29T04:48:23+00:00

This adds the POWER7+ cputable entry for the PVR 0x004a0000.  Rest is
the same as vanilla POWER7.

powerpc/fsl-booke: Add support for FSL 64-bit e5500 core

2010-10-14T05:55:03+00:00

The new e5500 core is similar to the e500mc core but adds 64-bit
support.  We support running it in 32-bit mode as it is identical to the
e500mc.
