 ========================
-By default the GPU firmware shipped is arm192. You can overwrite this using the
-variable RPI_GPU_FIRMWARE with one of the values below.
-# arm128 : 128M ARM, 128M GPU split
-# arm192 : 192M ARM, 64M GPU split
-# arm224 : 224M ARM, 32M GPU split
-# arm240 : 240M ARM, 16M GPU split
+Variable    : Details
+GPU_MEM     : GPU memory in megabyte. Sets the memory split between the ARM and GPU. ARM gets the remaining memory. Min 16. Default 64.
+GPU_MEM_256 : GPU memory in megabyte for the 256MB Raspberry Pi. Ignored by the 512MB RP. Overrides gpu_mem. Max 192. Default not set.
+GPU_MEM_512 : GPU memory in megabyte for the 512MB Raspberry Pi. Ignored by the 256MB RP. Overrides gpu_mem. Max 448. Default not set.
