New patch (non-damaged) including changes to b43-asm/test.asm
Regards,
-Francesco
The following changes are made to b43-tools
1) b43-asm assembles new instructions jdn, jdnz, jdp, jdpz, mul;
2) b43-asm new instructions added to test.asm source;
3) b43-dasm disassembles opcodes 0xD6, 0xD7, 0xD8, 0xD9, 0x101.
