A grep of current ARM Linux Kconfig's only shows 3 IXP systems setting CONFIG_CPU_BIG_ENDIAN. Perhaps you are correct about ability but few seem to use it.

So bit [7] of the system control register is ignored entirely, and if you write a 1 to it, nothing at all happens and the system boots as usual? (To test, add a line "OBJS += big-endian.o" to the top of arch/arm/boot/compressed/Makefile.) Does it also mean that the ARMv6 based OMAPs have the SETEND instruction behave as NOPs? -- To unsubscribe from this list: send the line "unsubscribe linux-omap" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
