From fa5cec032180a997b82b52f0b6075aa548a953cd Mon Sep 17 00:00:00 2001 From: Paul Burton Date: Fri, 8 Nov 2013 11:18:47 +0000 Subject: pci.h: allow inclusion in assembly source This patch simply #ifdef's out the C-specific parts of pci.h when it is included by an assembly file. This will allow the macros it contains to be used from assembly source as will be done in a followup commit adding support for more modern MIPS Malta boards.

The board is moved into an "imgtec" vendor directory at the same time in order to ready us for any other boards supported by Imagination in the future.

The system controller is detected at runtime allowing one U-boot binary to run on a Malta with either. Due to the PCI I/O base differing between Maltas using gt64120 & msc01 system controllers, the UART setup is modified slightly. A second UART is added so that there is one pointing at the correct address for each system controller. The Malta board then defines its own default_serial_console function to select the correct one at runtime. The incorrect UART will simply not function. Tested on: - A coreFPGA6 Malta running interAptiv and proAptiv bitstreams, both with and without an L2 cache. - QEMU.

CONFIG_PCNET_79C973, PCNET_HAS_PROM, CONFIG_CMD_DHCP This model of the pcnet is used in current Malta boards, at least in the Malta-R rev 3. Enable support for it. The Malta also has the ethernet controller PROM containing its MAC address, so enable support for that in order to read that MAC address. DHCP is a very useful feature to have available for many networks, enable support for it also.
