Subject: Re: Linux 2.4 Kernel on Xilinx Virtex4 FX100's PPC

There are some silicon issues on the PPC405 in V4 with PVR 0x20011430=20
which are documented in Xilinx solution record 20658. All these issues=20
are fixed in silicon where the PPC405 has a PVR of 0x20011470.

Said that it's not true that the caches cannot be used in silicon with=20
PVR 0x20011430. The problem is a corner case which does not show in=20
typical designs.
