From 48f1d5a3cef5782cbc7a32c29f1eda2342877c13 Mon Sep 17 00:00:00 2001 From: Linus Walleij Date: Fri, 2 Jul 2010 10:24:03 +0100 Subject: ARM: 6204/1: Fixups for the RealView PB1176 This is a number of basic fixes to the PB1176 that makes it tick properly: - Detect MMC insertion/removal even when PL061 GPIO is not compiled in. The register to read this status directly is removed on the PB1176. - Define the UART3 on the DevChip (where is actually is) and define the new UART4 serial port on the FPGA. - Also define the clocks for these two UARTs apropriately. - Remove the false notion that the PB1176 should have its CLCD on the ISSP, this is not the case, it is in the DevChip. - Remove the defintions and the previously commented-out PL081 DMAC. As confirmed by mail this was found to be broken on the PB1176 board and removed from the subsequent FPGA images.
