[yocto] Unable to get serial console login prompt - PowerPC 440 Virtex 5 processor

Hi Khem,
                  What should I do to enable multilib in gcc-4.7? 

I think at the moment, in gcc-configure-common.inc, it is disabled.

If I were to re-enable it as follows, based on what I've diff'd from the Denx ELDK repo, what how does the GCCMULTILIB variable evaluate?

-GCCMULTILIB = "--disable-multilib"
+GCCMULTILIB = '${@base_contains("MULTILIB_ARCH_LIST", "${TARGET_ARCH}", "--enable-multilib", "--disable-multilib",d)}'

I think multilib has to be enabled, no? 

In file gcc/config/rs6000/t-ppcos.c

# Multilibs for a powerpc hosted ELF target (linux, SVR4)

MULTILIB_OPTIONS	= msoft-float
MULTILIB_DIRNAMES	= nof
MULTILIB_EXTRA_OPTS	= fPIC mstrict-align
MULTILIB_EXCEPTIONS	= 

MULTILIB_MATCHES	= ${MULTILIB_MATCHES_FLOAT}


Here is the full patch, which I am assuming enables multilib, and get libgcc to generate the nof libraries to the target:
