[mc1322x] CodeSourcery , flash loader

[Andrew Pullin]

One of their older version of the CodeCourcery toolchain seems to 
compile everything without errors.
The "2008q1-126" release, here: 
http://www.codesourcery.com/sgpp/lite/arm/portal/release323

Everything I've tried works (printf, flasher, blink), although the code 
size is a little bigger than the latest release.

I guess that indicates that there is actually a bug in binutils/gas 
source tree, or at least the ARM port of it, for version 2.19.51 ? I 
submitted the bug to the CodeSourcery guys, although maybe I should also 
submit it to the binutils maintainers, too.
