8c453e9d3d imx: imx8ulp: enable wdog_ad interrupt in CMC1
Enable wdog_ad interrupt being triggered by CMC1 to CM33 to let CM33
know A35 reset and reinitialize rpmsg.
Clear wdog_ad and AD_PERIPH reset interrupt after A35 up, otherwise
M33 will always receive interrupt.

c916fb1747 imx: imx8ulp: Change LPAV assignment for dual boot
Assign the LPAV owner to RTD, and assign LPAV masters and peripherals
to APD. So except the masters and peripherals, other resources
(like DDR, cgc2, pcc5) in LPAV won't be reset during reboot and suspend.

No needs to initialize DDR again after reboot.

Enable MU0_B clk by default. When M33 image is loaded by Jlink,
the previous method not enable MU0_B clk and not able to communicate

And we not put it under kernel dts, because it conflicts with i.MX8QM

509b8e7ba1 imx: imx8ulp: cgc: Switch to NICLPAV to FRO192 before PLL4 init
When reset with dual boot mode, the LPAV domain won't power down
due to its master is not assigned to APD. So the NICLPAV keeps the
last setting to use PLL4PFD1. So before SPL initialize the PLL4,
we need to switch NICLPAV to FRO192, otherwise system will hang.

4ab38f6822 imx: imx8ulp_evk: Skip init DDR for reboot in dual boot mode
When M33 is LPAV owner in dual boot, DDR, PCC5, CGC2 won't be reset
during APD reset. So no need to init DDR again after reboot, but need to
reconfigure the PLL4 PFD/PFDDIV/LPAV NIC etc, because kernel may
change or disable some of them.

4de720e98d Merge branch 'master' of https://source.denx.de/u-boot/custodians/u-boot-sunxi
A big part is the DM pinctrl driver, which allows us to get rid of quite
some custom pinmux code and make the whole port much more robust. Many
thanks to Samuel for that nice contribution! There are some more or less
cosmetic warnings about missing clocks right now, I will send the trivial
fixes for that later.
Another big chunk is the mkimage upgrade, which adds RISC-V and TOC0
(secure images) support. Both features are unused at the moment, but I
have an always-secure board that will use that once the DT lands in the
kernel.
On top of those big things we have some smaller fixes, improving the
I2C DM support, fixing some H6/H616 early clock setup and improving the
eMMC boot partition support.

The gitlab CI completed successfully, including the build test for all
161 sunxi boards. I also boot tested on a A64, A20, H3, H6, and F1C100
board. USB, SD card, eMMC, and Ethernet all work there (where applicable).

b9a2e18533 sunxi: eMMC: Improve automatic boot source detection
When the Allwinner BROM loads the SPL from an eMMC boot partition, it
sets the boot source byte to the same value as when booting from the
user data partition. This prevents us from determining the boot source
to load U-Boot proper from the proper partition for sure.

The generic SPL MMC code already looks at the enabled boot partition
number, to load U-Boot proper from the same partition, but this fails
if there is nothing bootable in this partition, as the BROM then
silently falls back to the user data partition, which the SPL misses.

To learn about the actual boot source anyway, we repeat the algorithm
the BROM used to select the boot partition in the first place:
- Test EXT_CSD[179] to check if an eMMC boot partition is enabled.
- Test EXT_CSD[177] to check for valid MMC interface settings.
- Check if BOOT_ACK is enabled.
- Check the beginning of the first sector for a valid eGON signature.
- Load the whole SPL.
- Recalculate the checksum to verify the SPL is valid.

If one of those steps fails, we bail out and continue loading from the
user data partition. Otherwise we load from the selected boot partition.

Since the boot source is needed twice in the boot process, we cache the
result of this test to avoid doing this costly test multiple times.

This allows the very same image file to be put onto an SD card, into the
eMMC user data partition or into the eMMC boot partition, and safely
loads the whole of U-Boot from there.
