Thanks Scott.

I have to apologize here, after doing a search of the pdf (that same
UG11) I found the acronym. It is in fact a simplified form
of bclrl, and means Branch to Link Register and Link. I actually knew
that there are simplified mnemonics are utilized along
with complete ones in the PPC, but apparently my experience is short
so far. The problem's solved.

Thanks again,
Andrew

Hi All,

I was unable find a description of a PPC405 instruction "blrl". It
looks like a branch, but I never found it in the
manuals like UG11. The instruction use can be found in e.g.
edk_root/sw/lib/bsp/xilkernel_v4_00_a/src/syscall/arch/ppc405/
mksyscall.S

Thanks,
Andrew
