Re: [U-Boot] [RFC PATCH v2] ARM: Avoid compiler optimization for usages of readb, writeb and friends.

Hi Dirk,

But the issue with drivers/mtd/nand/omap_gpmc.c (i.e. the additional ldrb r3, [r3]) is still open? Has anybody tried to replace it with a nop in the binary to be sure this is the root cause?

Can you try and preprocess the C file for both the broken and working cases, then post the preprocessed C extract? Differences at the C level may help understanding differences at the asm level.

Thanks

Dirk

Amicalement,
