This is needed by 2/4 to get truly useable support. Please merge both
patches.
Re Fabio's question: the start.S is generic to mx27 -- IIUC, it could
also be applied to e.g. imx27lite or magnesium if these boards'
maintainers felt so inclined. Therefore it could indeed move into
arch/arm/cpu/arm926ejs/mx27.

Please avoid comments that paraphrase ASM in pseudo-C. Either remove
them or replace them with something that the ASM does not also say.
