[U-Boot] [PATCH] arm: Fix armv8 compilation error

[Steve Rae <srae@broadcom.com>]

Albert,

I don't think that there is any code currently submitted that triggers 
this error.
(it is "hidden" inside inline functions...)

However, you could add one line of code 'anywhere' to test this:
	test_and_set_bit(1, (volatile void *)0x12345678);

Thanks, Steve

PS.
- using: 
gcc-linaro-aarch64-linux-gnu-4.8-2014.01_linux/bin/aarch64-linux-gnu-
- and:    ./MAKEALL -a aarch64
