[U-Boot-Users] [PATCH 6/6] AT572D940HF-EB Support

Antonio R. Costa costa.antonior at gmail.com
Wed Jun 11 14:56:58 CEST 2008


Logic unit: Configuration files
Purpose:    Added AT572D940HF-EB to Makefile and mach-types, added config file
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
