[U-Boot] [PATCH] MIPS: Add VCT board series support (Part 1/3)

Stefan Roese sr at denx.de
Mon Dec 15 15:51:50 CET 2008


This patch adds support for the Micronas VCT board series.
Currently the following platforms are supported:

  vct_premium
  vct_premium_small
  vct_premium_onenand
  vct_premium_onenand_small
  vct_platinum
  vct_platinum_small
  vct_platinum_onenand
  vct_platinum_onenand_small
  vct_platinumavc
  vct_platinumavc_small
  vct_platinumavc_onenand
  vct_platinumavc_onenand_small

One speciality of the VCT board is that it can't access NOR FLASH
memory-mapped. It has to use special access functions for this.
