Next, problem: I tried to build for my BeagleBone, but the kernel
build failed with this error:
   | arch/arm/boot/compressed/head.S: Assembler messages:
   | arch/arm/boot/compressed/head.S:127: Error: selected processor does not support requested special purpose register -- `mrs r2,cpsr'
   | arch/arm/boot/compressed/head.S:134: Error: selected processor does not support requested special purpose register -- `mrs r2,cpsr'

   ERROR: Task 352 (/home/local/poky-multi/meta-ti/recipes-kernel/linux/linux-ti33x-psp_3.1.bb, do_compile) failed with exit code '1'

Looks like an incompatibility with the tools
   Angstrom = gcc-4.5-r45+svnr181733
   Yocto = gcc-cross-4.6.2+svnr181430-r20

Oh well...
