From: Bernd Schmidt Date: Wed, 23 Apr 2008 21:31:18 +0000 (+0800) Subject: [Blackfin] arch: Give the DMA base registers a more descriptive name X-Git-Url: https://git.karo-electronics.de/?a=commitdiff_plain;h=7795566495ff90c541a4654d3c903ab277abadfd;p=linux-beck.git [Blackfin] arch: Give the DMA base registers a more descriptive name The DMA base registers are available in a global named "base_addr" for every Blackfin variant. Give this a more descriptive name, and remove duplicate tables from some drivers.
