| bool "Enable BMEM reserved A/V memory" |
| depends on HAVE_MEMBLOCK && ARCH_BRCMSTB && BRCMSTB_MEMORY_API |
| help |
| The A/V peripherals (managed by the PI/Nexus middleware) require |
| large, contiguous memory regions to be set aside at boot time. This |
| option sets those up in a default config that reserves most of |
| memory. Also allows the user to manually define region sizes and |
| locations using the 'bmem' command line param. Allows for O_DIRECT |
| I/O using these regions, mmap() from user programs, and |
| ioremap() from kernel drivers. |

| This driver provides the ioctls for manipulating with the reserved |
| areas used by Broadcom middleware, as well as the functions for the |
