Logic unit: include/asm-arm/arch-at572d940hf (Part 2)
Purpose: AT572D940HF-EB include files (Part 2)
Author: Antnoio R. Costa <antonio.costa <at> atmel.com>
Date : 11 Jun 2008
Status:
- USB,MACB,MCI,DBGU,USARTS working
- Introduced interrput handling on reset to work around
a bug on SDRAM controller
- Introduced a function to compute system frequency at run-time
- Flashes initialised but not recognised
- Environment is built-in and temporarly stored in SDRAM
