On imx8m[m|p|q].dtsi, upstream Linux uses different names for NPU/VPU
IP block nodes. It leads variants without such HW block having it
enabled by default.
This patch adds the upstream Linux node's paths to the disable list while
keep the compatibility with downstream Linux.

Commit bfb3409d67 ("imx: toradex/apalis-imx8: correct SCU API usage")

is_quadplus = ((val >> 4) & 0x3) != 0x0;

The other changes in this commit are correct.
sc_misc_otp_fuse_read() returns 0 on a successful fuse read.
This inversion causes board_mem_get_layout() to report incorrect RAM size.

The intention of change_k0_cca() is to read the C0.Config register into
register $t0, update $t0 with the new cache coherency mode passed in $a0
and write back $t0 to C0.Config. With MIPS32 R2 or later instruction
sets, this can be achieved with a single instruction with INS. The
source and destination register of the INS instruction is passed as
first parameter. In case of change_k0_cca() it is register $t0. But
for writing back the updated value to C0.Config, the incorrect $a0
register is used. This is only correct in the MIPS32 R1 code path.
Fix the `mtc0` instruction to write back the value of the $t0 register.
Fix the MIPS32 R1 code path to also store the updated value in $t0.

The first multi-letter extension after the single-letter extensions does
not have to be preceded by an underscore, which could cause the parser
to mistakenly find a single-letter extension after the start of the
multi-letter portion of the string.
Three letters precede multi-letter extensions (s, x & z), none of which
are valid single-letter extensions. The dt-binding also allows
multi-letter extensions starting with h, but no such extension have been
frozen or ratified, and the unprivileged spec no longer uses "h" as a
prefix for multi-letter hypervisor extensions, having moved to "sh"
instead. For that reason, modify the parser to stop at s, x & z to prevent
this overrun, ignoring h.

U-Boot SPL loads the device-tree directly behind main U-Boot overlapping
the .bss section. reserve_fdt() is called in board_init_f() to relocate the

Debug UARTs are enabled before board_init_f(). With sbi_dbcn_available in

It appears that there is some timing marginality either in the
board layout or the SoC that results in occasional data corruption
on some boards.
We observed this issue on some of the new HiFive Unmatched RevB
boards during volume production as well as some of the original
HiFive Unmatched boards from 2021 in our possession. This means
that there are other boards out there that might have the issue
too.

faulty boards (failing at 1866MT/s) passed.
We plan further testing after we procure a temperature chamber.

Two patches make sure our DRAM init does not actually change the content
of the DRAM array, which allows to use DRAM for Linux' pstore
functionality.
We get SPI support for U-Boot proper for one more SoC, that patch was
lingering around for a while, and should not affect other SoCs, so I am
merging this now.
As an added bonus, we get the defconfig file for a new board, the DT was
already synced from the kernel tree.
The CI looked happy with changes, and I tested them on five different
