Hello
According to the errata sheet, the IBM405GPr doesn't suffer from the
ERR51 / CPU_190 and ERR77 / CPU_210 bugs as the IBM405GP does.
But the workarounds are still enabled in "arch/ppc/config.in".
Shouldn't there be something like this:
if [ "$CONFIG_405GPR" = "y" ]; then
define_bool CONFIG_IBM405_ERR51 n
define_bool CONFIG_IBM405_ERR77 n
fi

Right -- actually need to avoid defining the symbols at all (such as
removing ERR77 from the CONFIG_SYCAMORE case) since an "ifdef" check is
used (that should probably be fixed as well). We've just run the same
kernel binary on 405GP "Walnut" and 405GPr "Sycamore" boards, so haven't
been cleaning up the 405GPr specifics.

I just committed something like this to 2_4_devel and will be moved to
the other trees as well.
