Both real Malta boards & emulators that mimic Malta (eg. QEMU) can

which enables the user to make use of the whole 64 bit address space.

malta: Use device model & tree for UART

Make use of device model & device tree to probe the UART driver. This is
the initial step in bringing Malta up to date with driver model, and
allows for cleaner handling of the different I/O addresses for different
system controllers by specifying the ISA bus address instead of a
translated memory address.

MIPS: Support for targetting MIPSr6

Add support for targetting MIPS32r6 & MIPS64r6 systems, in the same way
that we currently select release 1 or release 2 targets. MIPSr6 is not
entirely backwards compatible with earlier releases of the architecture.
Some instructions are encoded differently, some are removed, some are
reused, so it is not practical to run U-Boot built for earlier revisions
on a MIPSr6 system. Update their Kconfig help text to reflect that.

MIPS: Simplify CONFIG_SYS_CPU values

Rather than having the values for CONFIG_SYS_CPU depend upon each

CONFIG_CPU_MIPS32 & CONFIG_CPU_MIPS64 which in turn depend upon the
architecture revisions.

This is done in preparation for adding MIPSr6 support, which would
otherwise need to introduce new cases here.

MIPS: Support dynamic I/O port base address

The existing mips_io_port_base variable isn't suitable for use early
during boot since it will be stored in the .data section which may not
be writable pre-relocation. Fix this by moving the I/O port base address
into struct arch_global_data. In order to avoid adding this field for
all targets, make this dependant upon a new Kconfig entry
CONFIG_DYNAMIC_IO_PORT_BASE. Malta is the only board which sets a
non-zero I/O port base, so select this option only for Malta.

MIPS: kconfig: add option for MIPS_L1_CACHE_SHIFT

Add Kconfig symbol for L1 cache shift like the kernel does.
The value of CONFIG_SYS_CACHELINE_SIZE is not a reliable source
for ARCH_DMA_MINALIGN anymore, because it is optional on MIPS.
If CONFIG_SYS_CACHELINE_SIZE is not defined by a board, the
cache sizes are automatically detected and ARCH_DMA_MINALIGN
would be set to 128 Bytes.

The default value for CONFIG_MIPS_L1_CACHE_SHIFT is 5 which
corresponds to 32 Bytes. All current MIPS boards already used
that value. While on it, fix the Malta board to use a value of 6
like the kernel port does.

Move default y configs out of arch/board Kconfig

Some archs/boards specify their own default by pre-defining the config
which causes the Kconfig system to mix up the order of the configs in
the defconfigs... This will cause merge pain if allowed to proliferate.

Remove the configs that behave this way from the archs.

A few configs still remain, but that is because they only exist as
defaults and do not have a proper Kconfig entry. Those appear to be:
