/* Broadcom UIF format
|
||||
*
|
||||
* This is the common format for the current Broadcom multimedia
|
||||
* blocks, including V3D 3.x and newer, newer video codecs, and
|
||||
* displays.
|
||||
*
|
||||
* 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.
