This board is a plug in card for Marvell's switch system development
kits. Form-factor aside it is similar to the DB-88F6820-GP with the
following differences.
- TCLK is 200MHz
- SPI1 is used
- No SATA
- No MMC
- NAND flash

88F6820 is a specific Armada-38x chip that is used on the DB-88F6820-GP
board. Rather than having DB_88F6820_GP and TARGET_DB_88F6820_GP which
selects the former. Rename DB_88F6820_GP to 88F6820 so that other boards
using the 88F6820 can be added.
Stefan:
Change 88F6820 for clearfog as well.

Now, include/linux/errno.h is a wrapper of <asm-generic/errno.h>.
Replace all include directives for <asm-generic/errno.h> with
<linux/errno.h>.
<asm-generic/...> is supposed to be included from <asm/...> when
arch-headers fall back into generic implementation. Generally, they
should not be directly included from .c files.

Unlike Linux, nothing about errno.h is arch-specific in U-Boot.
As you see, all of arch/${ARCH}/include/asm/errno.h is just a
wrapper of <asm-generic/errno.h>. Actually, U-Boot does not
export headers to user-space, so we just have to care about the
consistency in the U-Boot tree.
Now all of include directives for <asm/errno.h> are gone.
Deprecate <asm/errno.h>.

As I repeated in the ML, I am unhappy with config entries with bare
defaults. Kick them out of arch/arm/mach-uniphier/Kconfig.
Currently, CONFIG_SPL_SERIAL_SUPPORT is not user-configurable
(build fails without it), but it should be fixed later anyway,
so I am moving CONFIG_SPL_SERIAL_SUPPORT to defconfigs.

SPL needs to have bigger stack size because of USB.
Simple malloc needs to be disabled because dfu code requires different
allocation functions. There is no space in OCM that's why random place
in DDR is used.
BOOTD must be disabled because it is causing compilation error.
All variables are disabled and used only variables valid for DFU because
they are simple huge. Including automatic variables added by
CONFIG_ENV_VARS_UBOOT_CONFIG.
Hardcode addresses for u-boot, atf, kernel and dtb
just for SPL DFU code.

Some systems are configured such that multiple CPUs begin running from
their reset vector following a system reset. If this occurs then U-Boot
will be run on multiple CPUs simultaneously, which causes all sorts of
issues as the multiple instances of U-Boot clobber each other.
Prevent this from happening by simply hanging with an infinite loop if
we run on a CPU whose ID, as determined by GlobalNumber or EBase.CPUNum
as appropriate, is non-zero.

The relocate_code function was handling cache maintenance incorrectly.
It copied U-Boot to its new location, flushed the caches & then
proceeded to apply relocations & jump to the new code without flushing
the caches again. This is problematic as the instruction cache could
potentially have already fetched instructions that hadn't had relocs
applied.
Rework this to perform the flush_cache call using the code in the
original copy of U-Boot, after having applied relocations to the new
copy of U-Boot. The new U-Boot can then be jumped to safely once that
cache flush has been performed.
As part of this, since the old U-Boot is used up until after that cache
flush, complexity around loading values from the GOT using a jump & link
instruction & loads from a table is removed. Instead we can simply load
the needed values with PTR_LA fromt the original GOT.

This patch introduces support for building U-Boot to run on the MIPS
Boston development board. This is a board built around an FPGA & an
Intel EG20T Platform Controller Hub, used largely as part of the
development of new CPUs and their software support. It is essentially
the successor to the older MIPS Malta board.

Ensure that cache operations complete before returning from
mips_cache_reset by placing a completion barrier (sync instruction)
before the return. Without this there is no guarantee that the cache ops
will complete before any subsequent memory accesses, since they are
indexed cache ops & thus not implicitly ordered with memory accesses.

Writing to the coprocessor 0 TagLo registers introduces an execution
hazard in that we need that write to complete before any cache

During boot we set Config.K0=2 (uncached) such that any accesses to the
kseg0 memory region are performed uncached before the caches are
initialised. This write to the Config register introduces an execution
hazard between it & any following memory accesses (such as the load of
_gp), which we need to clear in order to ensure those memory accesses
are actually performed uncached. Clear this execution hazard with the
insertion of an ehb execution hazard barrier instruction.

MIPS Linux expects the bootloader to leave the boot CPU a member of the
coherent domain when running on a system with a CM, and we will need to
do so if we wish to make use of IOCUs to have cache-coherent DMA in
U-Boot (and on some systems there is no choice in that matter). When a
CM is present, join the coherent domain after completing cache
initialisation.

This patch adds support for initialising & maintaining L2 caches on MIPS
systems. The L2 cache configuration may be advertised through either
coprocessor 0 or the MIPS Coherence Manager depending upon the system,
and support for both is included.
If the L2 can be bypassed then we bypass it early in boot & initialise
the L1 caches first, such that we can start making use of the L1
instruction cache as early as possible. Otherwise we initialise the L2
first such that the L1s have no opportunity to generate access to the
uninitialised L2.
