Without setting up the PIRQ[A:D] interrupt routes, PCI interrupts will
be left disabled. Linux does not set up this routing but relies upon it
having been set up by the bootloader, reading back the IRQ lines which
the PIRQ[A:D] signals have been routed to.
This patch routes PIRQA & PIRQB to IRQ 10, and PIRQC & PIRQD to IRQ 11.
This matches the setup used by YAMON.

Displaying a message on the LCD screen is a simple yet effective way to
show the user that the board has booted successfully.

This patch adds support for running on Malta boards using coreFPGA6
core cards, including support for the msc01 system controller used
with them. 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.

Move the GT64120 register base to 0x1be00000
and setup PCI BAR registers as done by the
original YAMON bootloader.
This is needed for running Linux kernel.

The MIPS Malta board has a SOFTRES register. Writing a
magic value into that register initiates a board reset.
Use this feature to implement reset support.

Add minimal support for the MIPS Malta CoreLV board
emulated by Qemu. The only supported peripherial is
the UART.
This is enough to boot U-Boot to the command prompt
both in little and big endian mode.
