PPC 405 port complains about 'tlbwe' opcode

Hi There,

I am in the process of porting linux-2.4.18 with
ppc-patch-2.4.18 to make a 405 linux os. For 'make
bzImage' it complains about 'tlbwe' being Unrecognied
opcode from head_4xx.S.

-------
powerpc-eabi-gcc -D__ASSEMBLY__ -D__KERNEL__
-I/root/ppctest/linux/include -c -o head_4xx.o
head_4xx.S
head_4xx.S: Assember messages:
head_4xx.S:111: Error: Unrecognized opcode: `tlbwe`
head_4xx.S:112: Error: Unrecognized opcode: `tlbwe`
make[1]: *** [head_4xx.o] Error 1
-------

I saw couple of postings saying that 'tlbwe' is not a
405 opcode. But it is defined by PPC-405 manual. I am
not sure what WS value should be, if i have to add
'tlbwe' to supported opcodes.

Please suggest. If you can share a PPC-405 port for
linux or any other embedded free OS, please let me
know.

thanks in advance,
Prakash

You need to pass down to the assembler an option to enable 403/405
instructions.  Add a -Wa,-m405 to the gcc line.
