Hi Albert,

Another option would be to remove all the irq_off/_on stuff from the atomic_foo() and the bitops functions. We are running in a single-threaded environment after all in U-Boot. So there should be no need for such synch mechanisms. But these files are copied from Linux. And I really don't like to make changes to these files.

And ideas / comments welcome.

I have an idea, only moderately better, embodied in my V2 patch.

Basically, for Thumb-1 builds, I insert an include path which allows me to "intercept" includes of 'asm/proc-armv/system.h' and provide ad hoc definitions for local_* definitions.

Thanks, Stefan

Amicalement,
