   4 Subject: [PATCH] mtd/ps3vram: Add ps3vram driver for accessing video RAM as MTD
   5
   6 Add ps3vram driver, which exposes unused video RAM on the PS3 as a MTD
   7 device suitable for storage or swap.  Fast data transfer is achieved
   8 using a local cache in system RAM and DMA transfers via the GPU.
