U-Boot does not implement down_write_trylock() and its stub always returns
true that lock was acquired. Therefore ubifs_assert_cmt_locked() assert
currently always fails.
Fix this issue by redefining ubifs_assert_cmt_locked() to just empty stub
as there is nothing to assert.
One prominent feature is the restructering of the clock driver, which
allows to end up with one actual driver for all variants, although we
still only compile in support for one SoC.
Also contained are some initial SPI fixes, which should fix some
problems, and enable SPI flash support for the F1C100s SoC. Those
patches revealed more problems, I will queue fixes later on, but for
now it should at least still work.
Apart from some smaller fixes (for instance for NAND operation), there
is also preparation for the upcoming Allwinner D1 support, in form of
the USB PHY driver. There are more driver support patches to come.
The gitlab CI completed successfully, including the build test for all
160 sunxi boards. I also boot tested on a few boards, but didn't have
time for more elaborate tests this time.
The size of the dynamic stack allocation here is bounded by the if()
statement. However, just allocating the maximum size up-front and
doing malloc() if necessary avoids code duplication (the
i2c_setup_offset() until the invocation of ->xfer), and generates much
better (smaller) code:
bloat-o-meter drivers/i2c/i2c-uclass.o.{0,1}
add/remove: 0/0 grow/shrink: 0/1 up/down: 0/-144 (-144)
Function old new delta
dm_i2c_write 552 408 -144
Total: Before=3828, After=3684, chg -3.76%
It also makes static analysis of maximum stack usage (using the .su
files that are automatically generated during build) easier if there
are no lines saying "dynamic".
[This is not entirely equivalent to the existing code; this now uses
the stack for len <= 64 rather than len <= 63, but that seems like a
more natural limit.]

The SPI controllers in the Allwinner F1Cx00 series of SoCs are
compatible to the H3 IP. The only difference in the integration is
the missing mod clock in the F1C100, instead the SPI clock is directly
derived from the AHB clock.
We *should* be able to model this through the DT, but the addition of
get_rate() requires quite some refactoring, so it's not really worth in
this simple case: We programmed both the PLL_PERIPH to 600 MHz and the
PLL/AHB divider to 3 in the SPL, so we know the SPI base clock is 200
MHz. Since we used a hard coded fixed clock rate of 24 MHz for all the
other SoCs so far, we can as well do the same for the F1C100.
Define the SPI input clock and maximum frequency differently when
compiling for the F1C100 SoC.
Also adjust the power-of-2 divider programming, because that uses a
"minus one" encoding, compared to the other SoCs.
This allows to enable SPI flash support for the F1C100 boards.

spi: sunxi: improve SPI clock calculation
The current SPI clock divider calculation has two problems:
- We use a normal round-down division, which results in a divider
typically being too small, resulting in a too high frequency on the bus.
- The calculaction for the power-of-two divider is very inaccurate, and
again rounds down, which might lead to wild bus frequencies.
This wasn't a real problem so far, since most chips can handle slightly
higher bus frequencies just fine. Also the actual speed was mostly lost
anyway, due to release_bus() reseting the device. And the power-of-2
calculation was probably never used, because it only applies to
frequencies below 47 KHz.
However this will become a problem for the F1C100s support, due to its
much higher base frequency.
Calculate a safe divider correctly (using round-up), and re-use that
value when calculating the power-of-2 value. We also separate the
maximum frequency and the input clock on the way, since they will be
different for the F1C100s.

spi: sunxi: refactor SPI speed/mode programming
As George rightfully pointed out [1], the spi-sunxi driver programs the
speed and mode settings only when the respective functions are called,
but this gets lost over a call to release_bus(). That asserts the
reset line, thus forces each SPI register back to its default value.
Adding to that, trying to program SPI_CCR and SPI_TCR might be pointless
in the first place, when the reset line is still asserted (before
claim_bus()), so those setting won't apply most of the time. In reality
I see two nested claim_bus() calls for the first use, so settings between
the two would work (for instance for the initial "sf probe"). However
later on the speed setting is not programmed into the hardware anymore.
So far we get away with that default frequency, because that is a rather
tame 24 MHz, which most SPI flash chips can handle just fine.
Move the actual register programming into a separate function, and use
.set_speed and .set_mode just to set the variables in our priv structure.
Then we only call this new function in claim_bus(), when we are sure
that register accesses actually work and are preserved.

spl: spl_legacy: fix the use of SPL_COPY_PAYLOAD_ONLY
If the payload is compressed, SPL_COPY_PAYLOAD_ONLY should always be set
since the payload will not be directly read to its load address. The
payload will first be read to a temporary buffer, and then be decompressed
to its load address, without image header.
If the payload is not compressed, and SPL_COPY_PAYLOAD_ONLY is set, image
header should be skipped on loading. Otherwise image header should also be
read to its load address.

net: mediatek: use regmap api to modify ethsys registers
The address returned by regmap_get_range() is not remapped. Directly r/w

But for MIPS platform only virtual address should be used for access.
To solve this issue, the regmap api regmap_read/regmap_write should be used

net: mediatek: remap iobase address
The iobase address from dts node is actually physical address. It's
identical to the virtual address in ARM platform. This is ok because this
driver was used only by ARM platforms (mt7622/mt7623 ...).
But now this driver will be used by mt7621 which is a MIPS SoC. For MIPS
platform the physical address space is mapped to KSEG0 and KSEG1 and this
makes the virtual address apparently not idential to its physical address.
To solve this issue, this patch replaces dev_read_addr with dev_remap_addr
to get the remapped iobase address.

This patch adds support for noncached_alloc() which was only supported by

Unlike the ARM platform, MMU is not used in u-boot for MIPS. Instead, KSEG

1. MMU is untouched in noncached_set_region()
2. Address returned by noncached_alloc() is converted using KSEG1ADDR()
