arm: imx8: select ARCH_MISC_INIT if FSL_CAAM is enabled
Commit 2a7acc865b9d ("configs: colibri-imx8x: enable RNG support for KASLR")
enables FSL_CAAM which requires initialization in arch_misc_init().
The ARCH_MISC_INIT configuration was added to the relevant defconfig.
Commit d0ed9636902b ("global: Make ARCH_MISC_INIT a selected symbol")
changed ARCH_MISC_INIT to require explicit selection by the developer.
With this change the colibri-imx8x defconfig is no longer sufficient to
enable ARCH_MISC_INIT when FSL_CAAM is selected.
Add the necessary selection to automatically enable ARCH_MISC_INIT when
FSL_CAAM is enabled on i.MX8 platforms.

The repeated "lookup and request" pattern in spl_board_init() suggests
a low-hanging fruit for reducing the code size. This reduces the
object size of spl/board/liebherr/btt/btt.o by 300 bytes.

anything to do if it fails, so I suppose the printfs are the best that

thermal: imx_tmu: Always set thermal trips from fuses
NXP i.MX SoCs are available in different temperature grades. By default,
device-tree contains only thermal trips for consumer grade parts. On the
other hand, part temp grade fuse can be used to determine thermal trip
points. We already do this in imx_tmu_bind() function. Now, factor out
this functionality to a standalone function imx_tmu_set_trips() and use
it for both cases. This fixes an issue where 'cpu-thermal' child device
would set different thermal trips than the parent 'tmu@44482000' sensor,

No big features this time, mostly a collection of patches that have been
lying around for a bit. There are some DT updates, for those SoCs that
do not use OF_UPSTREAM yet, hopefully that's the last time we need to do
this exercise. And that's offset by switching over two more SoCs to
OF_UPSTREAM. Two new boards get a defconfig, and some improvements for
the sun8i-emac Ethernet driver. Finally a patch that fixes occassional
DRAM size misdetection for new A523 boards.
There are a few outstanding patches that just wait for getting some
details confirmed, which I might send then later.
CI passed, and I tested this briefly on affected boards.

sunxi: dts: arm: update devicetree files from Linux kernel tree
Sync the kernel devicetree source files for the Allwinner SoCs with
32-bit cores that do not use OF_UPSTREAM yet. The files were taken
from a v6.18-rc1 tree.
To maintain ABI compatibility with existing LTS kernels, one change
moving some IP blocks to the r_intc interrupt controller is excluded.
This effectively reverts Linux commits 994e5818392c and 9fdef3c3d8c2.
This commit also adds a new board devicetree for the A33 Vstar board,
plus one DT overlay for the OrangePi Zero interface board.
This update should not impact any existing U-Boot functionality.

sunxi: dts: arm64: update devicetree files from Linux kernel tree
Sync the devicetree files from the official Linux kernel tree, v6.18-rc1.
This is covering Allwinner SoCs with 64-bit ARM cores.
The bulk is cosmetic changes: board model name changes, DT node renames,
whitespace fixes.
The actual changes are not dramatic: the CPU cores get their caches
described properly, some A64 video clocks get fixed, some A64 boards
describe the header pins for the WiFi module, the Pinephone adds an
alternative magnetometer used on some board revisions.
On the H5 side the microSD slots get marked as having no write-protect
detection, and the NanoPi Neo Plus2 board describes its regulators better.
The H6 boards switch from RSB to I2C for their PMIC connection.
As before, this omits the non-backwards compatible changes to the R_INTC
controller, to remain compatible with older kernels.

sunxi: switch Allwinner A80 boards to OF_UPSTREAM
In contrast to some other Allwinner SoCs, there is no difference between
the DTs for the Allwinner A80 SoCs (sun9i) between the U-Boot and the
Linux kernel repository.
Remove the old copies of the A80 related .dts and .dtsi files, and switch
most of sun9i boards over to use OF_UPSTREAM.
There is the Sunchip CX-A99 (family of) board(s) for which we don't have
a DT in the kernel tree. Keep the .dts file in the legacy U-Boot DT
directory, and let the board's defconfig opt out of OF_UPSTREAM.

net: sun8i-emac: Add support for active-low leds with internal PHY
A device-tree property is already defined to indicate that the internal
PHY should be used with active-low leds, which corresponds to a
specific bit in the dedicated syscon register.
Add support for setting this bit when the property is present.

Makefile: pass KEYDIR when set to sunxi-spl.bin mkimage
Currently we pass this for u-boot-spl.kwb targets, however when
building sunxi-spl.bin in the TOC0 format we may also need to
specify a KEYDIR, as such we should also pass this when set

sunxi: a523: Re-use H6/H616 DRAM size detection method
The H6 and H616 DRAM initialisation code recently gained a joint and

DRAM size misdetection.
Use the same code for the A523 DRAM initialisation as well, which
suffers from the same misdetection at times.
