Until now, we've had to limit Raspberry Pi to 256MB of CMA memory to keep from triggering the hardware addressing bug between the tile binner and the tile alloc memory (where the top 4 bits come from the tile state data array's address). To work around that and allow more memory to be reserved for graphics, allocate a single BO to store tile state data arrays and tile alloc/overflow memory while the GPU is active, and make sure that that one BO doesn't happen to cross a 256MB boundary. With that in place, we can allocate textures and shaders anywhere in system memory (still contiguous, of course).

README
Linux kernel ============ This file was moved to Documentation/admin-guide/README.rst Please notice that there are several guides for kernel developers and users. These guides can be rendered in a number of formats, like HTML and PDF. In order to build the documentation, use ``make htmldocs`` or ``make pdfdocs``. There are various text files in the Documentation/ subdirectory, several of them using the Restructured Text markup notation. See Documentation/00-INDEX for a list of what is contained in each file. Please read the Documentation/process/changes.rst file, as it contains the requirements for building and running the kernel, and information about the problems which may result by upgrading your kernel.
