From: Steven Toth Date: Mon, 19 Mar 2007 21:01:07 +0000 (-0300) Subject: V4L/DVB (6155): Cleanup/remove code to access the sram memory maps X-Git-Url: https://git.karo-electronics.de/?a=commitdiff_plain;h=3328e4fbf10a2c2513d4de662ab251e0f4cb7c3e;p=linux-beck.git V4L/DVB (6155): Cleanup/remove code to access the sram memory maps The cx23885 and cx23887 family use two different memory maps which govern how the internal SRAM is configured. This patch streamlines the access to those structures.
