This patch adds support for displaying CPU type information about Atmel AT91 cores during boot. It currently only configures it for the at91sam9261ek board, but it can easily be configured for all at91 based cores.
please do this in two seperate patch please ask Stelian CC btw please use git
This patch also provides at91_dbgu.h which is also used by the upcoming USB CDC-ethernet and USB-gadget support for this board.

could you use the CONFIG_ARM926EJS and other configs to reduce the size impact
- switch ((cidr & AT91_CIDR_EPROC) >> 5) {
- case 0x1: txt = "ARM946ES"; break;
- case 0x2: txt = "ARM7TDMI"; break;

- case 0x5: txt = "ARM926EJS"; break;
- default: txt = "undefined"; break;
- }
- printf("Embedded Processor: %s\n", txt);
otherwise ok
