I had to drop this one, it breaks compilation on omap based boards:

arch/arm/mach-omap/xload.c: In function 'omap_xload':
arch/arm/mach-omap/xload.c:207:20: error: 'am33xx_bootinfo' undeclared (first use in this function)
arch/arm/mach-omap/xload.c:207:20: note: each undeclared identifier is reported only once for each function it appears in
arch/arm/mach-omap/xload.c:210:2: warning: passing argument 1 of 'func' makes pointer from integer without a cast [enabled by default]
arch/arm/mach-omap/xload.c:210:2: note: expected 'void *' but argument is of type 'uint32_t'
