Hangup booting Linux on PPC440GP

[Steve Boorman]

Many thanks to Chris Zimman for the following suggestion which fixed my problem.

>> Do you have math emulation compiled into the kernel?

Once this was configured  the system boots up fine. I overlooked this as being the
cause for several reasons:-

1) Using ebony_defconfig as the kernel config file should, I would have thought, set
CONFIG_MATH_EMULATION=y but it does not.

2) I would not have thought my simple printf of some text
would use floating point code.

3) I expected the kernel to panic with some form of illegal
instruction trap if floating point instructions were being
attempted with no emulator code present.
