[PATCH] ps3: Preallocate bootmem memory for ps3fb
Preallocate bootmem memory for the PS3 frame buffer device, which needs a large block of physically-contiguous memory. The size of this memory block is configurable: - The config option CONFIG_FB_PS3_DEFAULT_SIZE_M allows to specify the default amount of memory (in MiB) allocated to the virtual frame buffer. - The early boot parameter `ps3fb=xxx' allows to override the default value. It will be rounded up to a multiple of 1 MiB, if needed.
