Re: [U-Boot] [PATCH v4] ARM: Avoid compiler optimization for readb, writeb and friends.

gcc 4.5.1 seems to ignore (at least some) volatile definitions, avoid that as done in the kernel.

Have had a look at the asm generated by gcc 4.5.1, looks good.

The wrong optimization in arch/arm/cpu/armv7/omap3/clock.c is gone and the writeb in drivers/mtd/nand/omap_gpmc.c doesn't have the problem as the v1-patch.

Reagards,
