spi: Transform the FSL QuadSPI driver to use the SPI MEM API
To support the SPI MEM API, instead of modifying the existing U-Boot
driver, this patch adds a port of the existing Linux driver.
This also has the advantage that porting changes and fixes from Linux will
be easier.
Porting of driver left most of the functions unchanged while few of the
changes are:
-Remove lock(mutexes) and irq handler as u-boot is a single core execution.
-Remove invalid masterid as it was required specially for multicore
execution in LS2088ARDB which is not the case in u-boot.
-Remove clock support as changing spi speed is not supported in uboot and
nor in linux.
Currently tested on LS1088ARDB, LS1012ARDB, LS1046ARDB, LS1046AFRWY,
LS1043AQDS, LS1021ATWR, LS2088ARDB, I.MX6ULL EVK.

kbuild: SPL/TPL: generate separate asm-offsets.h for SPL and TPL
Currently generic-asm-offsets.h and asm-offsets.h are generated based
on U-Boot proper config options. The same asm-offsets headers are used
for building U-Boot SPL/TPL, which causes potential offset mismatch if
U-Boot proper has different config options from U-Boot SPL/TPL.
This commit adds:
spl/include/generated/(generic-)asm-offsets.h
tpl/include/generated/(generic-)asm-offsets.h
spl/include/generated/(generic-)asm-offsets.h is generated if
CONFIG_SPL=y, and included when building SPL.
tpl/include/generated/(generic-)asm-offsets.h is generated if
CONFIG_TPL=y, and included when building TPL.
They are created before Kbuild descends into SPL/TPL object directories
and builds $(obj)/dts/dt-platdata.o because $(obj)/dts/dt-platdata.c
includes a bunch of headers.
Prepend -I$(obj)/include to $(UBOOTINCLUDE) so (generic-)asm-offsets.h
is searched in {spl,tpl}/include/generated/.

fs: ext4: skip journal state if fs has metadata_csum
As u-boot doesn't support the metadata_csum feature, writing to a
filesystem with this feature enabled will fail, as expected. However,
during the process, a journal state check is performed, which could
result in:
- a fs recovery if the fs wasn't umounted properly
- the fs being marked dirty
Both these cases result in a superblock change, leading to a mismatch
between the superblock checksum and its contents. Therefore, Linux will
consider the filesystem heavily corrupted and will require e2fsck to be
run manually to boot.
By bypassing the journal state check, this patch ensures the superblock
won't be corrupted if the filesystem has metadata_csum feature enabled.

tools: fw_env: use erasesize from MEMGETINFO ioctl
We have a board with several revisions. The older ones use a nor flash
with 64k erase size, while the newer have a flash with 4k sectors. The
environment size is 8k.
Currently, we have to put a column containing 0x10000 (64k) in
fw_env.config in order for it to work on the older boards. But that
ends up wasting quite a lot of time on the newer boards that could
just erase the 8k occupied by the environment - strace says the 64k
erase takes 0.405 seconds. With this patch, as expected, that's about
an 8-fold better, at 0.043 seconds.
Having different fw_env.config files for the different revisions is
highly impractical, and the correct information is already available
right at our fingertips. So use the erasesize returned by the
MEMGETINFO ioctl when the fourth and fifth columns (sector size and
#sectors, respectively) are absent or contain 0, a case where the
logic previously used to use the environment size as erase size (and
consequently computed ENVSECTORS(dev) as 1).
As I'm only testing this on a NOR flash, I'm only changing the logic
for that case, though I think it should be possible for the other
types as well.

mips: mtmips: add SPL support
This patch adds SPL support for mtmips platform. The lowlevel architecture
is split into SPL and the rest parts are built into a memory loadable
u-boot image. Optional SPL_DM and OF_CONTROL are also supported.
The increment of size is very small (< 10 KiB) if SPL_DM and OF_CONTROL are
not enabled and the memory bootable u-boot (u-boot.img) is generated
automatically so there is not need to add a separate config for it.
A lzma compressed payload (u-boot-lzma.img) is also generated and it will
be combined with u-boot-spl.bin to form the unified ROM bootable binary
u-boot-mtmips.bin.
A spl loader is added to support uncompress the payload.

This patch rewrites the mtmips architecture with the following changes:
1. Move MT7628 soc parts into a subfolder.
2. Lock parts of D-Cache as temporary stack.
3. Reimplement DDR initialization in C language.
4. Reimplement DDR calibration in a clear logic.
5. Add full support for auto size detection for DDR1 and DDR2.
6. Use accurate CPU clock depending on the input xtal frequency for timer

mips: start.S: avoid overwriting outside gd when clearing global data in stack
When setting up initial stack, global data will also be put in the stack,
and being cleared.
The assembler instructions for clearing gd is as follows:
move t0, k0
1:
PTR_S zero, 0(t0)
blt t0, t1, 1b
PTR_ADDIU t0, PTRSIZE
t0 is the start address of gd, t1 is the end address of gd (t0 + GD_SIZE).
[PTR_ADDIU t0, PTRSIZE] is in the delay slot of [blt t0, t1, 1b], so it
will be executed before the branch operation.
However the comparison for the BLT instruction is done before executing the
delay slot. This means when the last word just before k1 is cleared, the
loop will continue to run once. This will clear an extra word at k1, which
is outside the global data.
Global data is placed at the top of the stack. If the initial stack is a
SRAM or locked cache, the area outside them may be inaccessible. A write
operation performed in this area may cause an exception.
To solve this, [PTR_ADDIU t0, PTRSIZE] should be placed before the BLT
instruction.

patman: Tidy up sys.path changes
Now that we are using absolute paths we can remove some of the sys.path
mangling that appears in the tools.
We only need to add the path to 'tools/' so that everything can find
modules relative to that directory.
The special paths for finding pylibfdt remain.

At present patman sets the python path on startup so that it can access

Add a 'make tcheck' option to test tools
Running all the unit tests takes a while and is not useful when you are
