0f832b9cdc malta: Allow MIPS64 builds
Both real Malta boards & emulators that mimic Malta (eg. QEMU) can
support MIPS64 CPUs. Allow MIPS64 builds of U-Boot for such boards,
which enables the user to make use of the whole 64 bit address space.

ec35e12331 MIPS: Move CONFIG_SYS_TEXT_BASE to Kconfig
Move CONFIG_SYS_TEXT_BASE to Kconfig, and add default values in board
Kconfig files matching what was present in their config headers. This
will make it cleaner to conditionalise the value for Malta based on 32
vs 64 bit builds.

2e7eb12e5c malta: Tidy up UART address selection
The address of the UART differs based upon the system controller because
it's actually within the I/O port region, which is in a different
location for each system controller. Rather than handling this as 2
UARTs with the correct one selected at runtime, use I/O port accessors
for the UART such that access to it gets translated into the I/O port
region automatically.

4685d4e90d malta: Remove ".set mips32" directive
We always build for a mips32 or higher ISA, so this ".set mips32"
directive is redundant. Once MIPSr6 support is added it will become
harmful since some instruction encodings change & this directive will
cause the older encodings to be incorrectly emitted instead of the
appropriate ones for the build.

In preparation for supporting MIPSr6, remove this redundant directive.

b41411954d linux/kernel.h: sync min, max, min3, max3 macros with Linux
U-Boot has never cared about the type when we get max/min of two
values, but Linux Kernel does.  This commit gets min, max, min3, max3
macros synced with the kernel introducing type checks.

Many of references of those macros must be fixed to suppress warnings.
We have two options:
 - Use min, max, min3, max3 only when the arguments have the same type
   (or add casts to the arguments)
 - Use min_t/max_t instead with the appropriate type for the first
   argument

Now the types of CONFIG_SYS_{ARCH, CPU, SOC, VENDOR, BOARD, CONFIG_NAME}

We can delete the ones in arch and board Kconfig files.

This commit can be easily reproduced by the following command:

/config[[:space:]]SYS_\(ARCH\|CPU\|SOC\|\VENDOR\|BOARD\|CONFIG_NAME\)/ {

93d4334f7f Add board MAINTAINERS files
We have switched to Kconfig and the boards.cfg file is going to
be removed. We have to retrieve the board status and maintainers
information from it.

The MAINTAINERS format as in Linux Kernel would be nice
because we can crib the scripts/get_maintainer.pl script.

After some discussion, we chose to put a MAINTAINERS file under each
board directory, not the top-level one because we want to collect
relevant information for a board into a single place.

TODO:
Modify get_maintainer.pl to scan multiple MAINTAINERS files.

dd84058d24 kconfig: add board Kconfig and defconfig files
This commit adds:
 - arch/${ARCH}/Kconfig
    provide a menu to select target boards
 - board/${VENDOR}/${BOARD}/Kconfig or board/${BOARD}/Kconfig
    set CONFIG macros to the appropriate values for each board
 - configs/${TARGET_BOARD}_defconfig
    default setting of each board

(This commit was automatically generated by a conversion script
based on boards.cfg)

In Linux Kernel, defconfig files are located under
arch/${ARCH}/configs/ directory.
It works in Linux Kernel since ARCH is always given from the
command line for cross compile.

But in U-Boot, ARCH is not given from the command line.
Which means we cannot know ARCH until the board configuration is done.
That is why all the "*_defconfig" files should be gathered into a
single directory ./configs/.

bea12b7823 malta: enable PIIX4 SERIRQ
Whilst U-boot does not require this itself, Linux currently relies upon
it having been muxed and enabled by the bootloader. Thus in order to
preserve compatibility with current kernels before a fix is merged in
Linux we will enable the SERIRQ interrupt and mux it to its pin.

Without doing this current kernels will never receive serial port
interrupts and the end result is typically that userland appears to
hang.

81f98bbd62 malta: setup PIIX4 interrupt route
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.

e174bd74c9 malta: disable L2 caches
Malta boards may be used with cores which support L2 caches, however
U-boot does not yet support L2 cache for MIPS. Thus for the moment we'll
disable L2 caches by setting the L2B bit in Config2. This is specific to
MTI/Imagination MIPS cores which is why this is done for the Malta board
rather than generically.

baf37f06c5 malta: support for coreFPGA6 boards
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.
