cover AT91CAP9 support
Hi,
This series of patches adds support for Atmel's AT91CAP9 Customizable Microcontrollers family:
http://www.atmel.com/products/AT91CAP/Default.asp
and more specifically for the AT91CAP9A-DK development kit:
http://www.atmel.com/dyn/products/tools_card.asp?tool_id=4138
The supported features include:
- SDRAM
- Serial port DBGU
- LEDs
- SPI
- NOR Flash
- NAND Flash with ECC soft
- DataFlash (through SPI)
- Ethernet
This patch is to be applied on top of the current u-boot git tree + three small patches I submitted a few days ago but weren't picked up by anyone:
http://article.gmane.org/gmane.comp.boot-loaders.u-boot/35306 http://article.gmane.org/gmane.comp.boot-loaders.u-boot/35307 http://article.gmane.org/gmane.comp.boot-loaders.u-boot/35309
This is the second submission of the AT91CAP9 support. Several changes have been done, some of them based on feedback from Haavard and Wolfgang:
- AT91CAP9.h file was simplified (going from over 400KB to less than a
tenth)
- atmel_usart driver is now used instead of the local driver
- a CodeSourcery specific workaround has been removed from the
submission
- more patch splitting for easier review
Thanks.

There are coding style issues in this patch; indentation not by TAB in board/at91cap9adk/Makefile,
I could not found any coding style issues in this particular file...
Quoted 1 line
board/at91cap9adk/at91cap9adk.cand probably elsewhere
But yes, there were many coding style problems all over the place. To my defense, a fair number of them were "imported" when I copied the files from other places (atmel supplied files or even u-boot tree...). But this is no excuse to not clean them before submitting new code.
I'm submitting a new version of the patches with hopefuly all coding style issues resolved.
