The above sentence doesn't quite parse though.

What are these aliases useful for ?
Also I think all DT related patches should be posted to
devicetree-discuss@xxxxxxxxxxxxxxxx as well.

It's probably better to add relevant entry at
arch/arm/mach-exynos/include/mach/map. It's just a one line, e.g.
/* x = 0...3 */
#define EXYNOS5_PA_GSC(x) (0x13e00000 + ((x) * 0x10000))
And use it here instead of plain numbers.
