PATCH: Raspberry Pi BSP version 2

Hi,
The following patch is for the Raspberry Pi BSP. I cleaned up a number
of issues including:
- fixed file header info
- renamed from raspberry_pi to raspberrypi
- converted console driver to the shared mode
- using the higher level interrupt calls in the clock driver
The BSP is still very basic and has a number of limitations:
- console is polled and hard coded at 115k
- benchmark timer code is present but does not seem to work properly
- support for many devices is still missing ( SD card, USB, Network,
Graphics console, etc ) But that leaves plenty of room for improvement
for GSOC students!
The BSP builds on the latest Git head, and all of the examples and tests
I have tried work. ( ticker, unlimited, hello, paranoia, a selection of
the sptests etc )
Please let me know if there are any more changes needed.
Thanks,
Alan

-BSP for the Raspberry Pi ARM board
-This is a basic port that should work on either Model A or Model B.
-
-It currently supports the following devices:
- o Console using the PL011 UART0
- The console driver only works with polled mode right now,
- the interrupt code is there, but it does not work yet.
- The console driver is currently hardcoded at 115k 8N1
- o Clock uses the internal ARM timer
- The Raspberry Pi can be overclocked through the config.txt file,
this
- would affect the duration of the clock tick.
- o Benchmark timer reads the lower 32 bit GPU timer register
-
-To run an RTEMS binary, it must be stripped and loaded on the SD card
along with
-the following files:
- bootcode.bin
- config.txt
- loader.bin
- start.elf
- kernel.img ( the RTEMS binary, you can change the name in config.txt )
-
-These files can be obtained from a Linux installation image, or from here:
-https://github.com/raspberrypi/firmware
-
-I used an old 256MB SD card to boot RTEMS.
-Much more information about the SD card file and bootloader can be
found here:
-http://elinux.org/RPi_Hub
-http://www.raspberrypi.org
-
-The linker script is set up for 128MB, so it can be used with a GPU/ARM
split
-of 128/128.
-The bootloader that is used on the SD card determines the split of RAM
between the
-ARM and the GPU. It might make sense to adjust the GPU/ARM memory split
to give
-more memory to RTEMS, especially on a 512MB board.
-
-To do:
- It would be nice to get support in the BSP for the following:
- o SD card
- o USB and USB 10/100 network chip on Model B
- o SPI
- o GPIO
- o ARM MMU
- o Graphics console
- o Sound
-
-Credits and links:
-
- There is a wealth of code and information to reference on the
raspberrypi.org bare metal forums:
- http://www.raspberrypi.org/phpBB3/viewforum.php?f=72
-
- I found information about how to program the timers, interrupts, and
UART 0
- from the examples provided by:
-
- David Welch:
- https://github.com/dwelch67/raspberrypi
- The readme file at his github repository has valuable information
about connecting a UART cable, JTAG etc.
-
- Steve Bate:
- http://www.stevebate.net/chibios-rpi/GettingStarted.html
- Steve provided a port of the Chibios RTOS to the raspberry Pi
-
- James Walmsley:
- http://www.raspberrypi.org/phpBB3/viewtopic.php?f=72&t=22423
- James ported FreeRTOS to the raspberry Pi.
