Simon, this patch breaks bootm (at least on powerpc), while booting an
compressed uImage (with DT). It just hangs while decompressing the
kernel image:

## Booting kernel from Legacy Image at 01000000 ...
   Image Name:   Linux-3.5.7
   Image Type:   PowerPC Linux Kernel Image (gzip compressed)
   Data Size:    2203312 Bytes = 2.1 MiB
   Load Address: 00000000
   Entry Point:  00000000
## Flattened Device Tree blob at 01800000
   Booting using the fdt blob at 0x1800000
   Uncompressing Kernel Image ...

I bisected mainline and this patch is the one that breaks booting:

[stefan at ubuntu-2012 u-boot ((983c72f...)|BISECTING)]$ git bisect good
35fc84fa1ff51e15ecd3e464dac87eb105ffed30 is the first bad commit

    Refactor the bootm command to reduce code duplication


I already looked what might be wrong but I couldn't find any problem
upon a quick glance. You know this code may better. Perhaps you could
take look at it and give it a try as well.

Thanks,
Stefan
