hw/sparc/leon3: Allow load of uImage firmwares
Currently the Leon3 machine doesn't allow to load legacy u-boot images:
$ qemu-system-sparc -M leon3_generic -d in_asm \
-kernel HelenOS-0.6.0-sparc32-leon3.bin
qemu-system-sparc: could not load kernel 'HelenOS-0.6.0-sparc32-leon3.bin'
$ file HelenOS-0.6.0-sparc32-leon3.bin
HelenOS-0.6.0-sparc32-leon3.bin: u-boot legacy uImage, HelenOS-0.6.0,\
Linux/ARM, OS Kernel Image (Not compressed), 2424229 bytes,\
Sun Dec 21 19:18:09 2014,\
Load Address: 0x40000000, Entry Point: 0x40000000,\
Header CRC: 0x8BCFA236, Data CRC: 0x37AD87DF
Since QEMU can load uImages, add the necessary code,
so the Leon3 machine can load these images:
$ qemu-system-sparc -M leon3_generic -d in_asm \
-kernel HelenOS-0.6.0-sparc32-leon3.bin
