[PATCH] Added interrupt handler for DMA channel 0, 1 & 2
Added macros for DMA channels 0-12
Added interrupt handlers for DMA 0, 1 & 2
The added IRQs are in accordance with the
BCM Peripherals Datasheet and also have been verified
with the linux source code for RPi

[PATCH] DMA : Added DMA API for Raspberrypi
Brief API Description
rpi_dma_init -> Initializes the channel structure
and its members for that particular channel, gets
the physical address of the control block structure
and installs the interrupt handler.
rpi_dma_allocate -> Allocates the channel if it is
not busy
rpi_dma_setup_dst & rpi_dma_setup_src -> These setup
src and dst parameters like dreq, width. Basically they
configure the info section of the control block structure
of that particular channel.
rpi_dma_setup_intr -> These will assign the handler
function for channel interrupt. This basically again
updates the channel structure with that function.
Note : rpi_dma_intr is the callback function for the
interrupt controller and calls this function internally.
rpi_dma_start -> Here you provide the virtual address,
the channel to be used and the width. Internally, it
converts the address to physical address and configures
the control block for that channel.
It flushes and invalidates the cache and writes the physical
address of the control block to a particular register
corresponding to the channel.
rpi_dma_free -> Frees the channel

[PATCH 0/5] POSIX Shared Memory Objects
These patches start to add support for POSIX Shared Memory Objects, see http://pubs.opengroup.org/onlinepubs/9699919799/functions/shm_open.html This support aims to improve POSIX compliance. The approach taken is to use the existing score Object as the basis for each shm object, where the Object.Name field directly relates to the name provided to shm_open(). So far the support for shm_open and ftruncate have been included. Support is needed for close() and shm_unlink(). A test is added based on some example code from an OS text book. This test also uses mmap() and munmap() which should be added to support mapping shared memory objects. The ability to specify shared memory management routines has been added.
