		/* Broadcom UIF format

		* This is the common format for the current Broadcom multimedia

		*
		* The image consists of utiles (64b blocks), UIF blocks (2x2 utiles),
		* and macroblocks (4x4 UIF blocks). Those 4x4 UIF block groups are
		* stored in columns, with padding between the columns to ensure that
		* moving from one column to the next doesn't hit the same SDRAM page
		* bank.
		*
		* To calculate the padding, it is assumed that each hardware block
		* and the software driving it knows the platform's SDRAM page size,
		* number of banks, and XOR address, and that it's identical between
		* all blocks using the format. This tiling modifier will use XOR as
		* necessary to reduce the padding. If a hardware block can't do XOR,
		* the assumption is that a no-XOR tiling modifier will be created.
