Wed Jun 11 14:56:54 CEST 2008


Logic unit: include/asm-arm/arch-at572d940hf (part 1)
Purpose:    AT572D940HF-EB include files (part 1)
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

Signed-off-by: Antonio R. Costa <antonio.costa at atmel.com>
