Hi Krzysztof,

Nice series! I haven't got much to add.

These partitions are not on eraseblock boundaries, so I assume you use
some script to combine barebox and firmware into a single image. Can we
integrate this into the make system or at least add some instructions
how to generate this image?

fls is defined in a similar way in arch/arm/include/asm/bitops.h:

#define fls(x) \
	(__builtin_constant_p(x) ? constant_fls(x) : \
	({ int __r; asm("clz\t%0, %1" : "=r"(__r) : "r"(x) : "cc"); 32-__r; }))

Or am I missing something?

Sascha
