93c4c0e4dd arm: dts: imx8mn-u-boot: Create common imx8mn-u-boot.dtsi
Multiple boards create duplicate entries in their respective
-u-boot.dtsi files which all basically do the same thing.
To consolidate these and make it easier to make improvements
going forward, consolidate them all into one place.

This file creates a flash.bin image using binman, and supports
LPDDR4, DDR4 and DDR3.  Since individual boards use different
peripherals and different UART ports, those entries were kept
in their respective board files, but the spba1 node was addded
which contains all UART1-3 to help facilitate SPL_DM_SERIAL.
Individual users will still need to include their respective
UART and pinctrl nodes for those UARTS.

This consolidated file also supports generating a flash.bin file
which can boot from flexSPI if CONFIG_FSPI_CONF_HEADER is
enabled.

c9473b2c37 imx8m: fix reading of DDR4 MR registers [again]
Commit 290ffe5788 (imx8m: fix reading of DDR4 MR registers) lifted a
private definition of lpddr4_mr_read() from imx8mm-cl-iot-gate board
code to drivers/ddr/imx/imx8m/ddrphy_utils.c, because that version
actually seems to work in practice.

However, commit 99c7cc58e1 (ddr: imx: Add i.MX9 DDR controller driver)
reintroduced the broken version in drivers/ddr/imx/imx8m/ddr_init.c,
copied most of the rest of ddrphy_utils.c to
drivers/ddr/imx/phy/ddrphy_utils.c, and stopped building
drivers/ddr/imx/imx8m/ddrphy_utils.c [and that file was then finally
completely removed with 7e9bd84883 (imx8m: ddrphy_utils: Remove unused
file)].

I assume this must have broken the imx8mm-cl-iot-gate board, at least
those that have not had their eeprom programmed with the proper
information. It certainly did break our out-of-tree board which always
reads back the ID register and uses that for a sanity check.

So apply the fix from 290ffe5788 once again.

559c5389c2 verdin-imx8mm: verdin-imx8mp: update env memory layout (again)
Update the distro config env memory layout for the Verdin iMX8M Mini and
Verdin iMX8M Plus again:

- loadaddr=0x48200000 allows for 128MB area for uncompressing (ie FIT
  images, kernel_comp_addr_r, kernel_comp_size)
- fdt_addr_r = loadaddr + 128MB - allows for 128MB kernel
- scriptaddr = fdt_addr_r + 512KB - allows for 512KB fdt
- ramdisk_addr_r = scriptaddr + 512KB - allows for 512KB script

Memory layout taken from commit fd5c7173ad
("imx8m{m,n}_venice: update env memory layout").

Note that for our regular BSP Layers and Reference Images for Yocto
Project an updated distro boot script is required (see
meta-toradex-bsp-common/recipes-bsp/u-boot/u-boot-distro-boot).

Note that this corrects a pre-maturely applied version 2 of the same
patch set.

ddc8d36a74 cyclic: Don't disable cylic function upon exceeding CPU time
With the migration of the watchdog infrastructure to cyclic functions
it's been noticed, that at least one watchdog driver is broken now. As
the execution time of it's watchdog reset function is quite long.

In general it's not really necessary (right now) to disable the cyclic
function upon exceeding CPU time usage. So instead of disabling the
cylic function in this case, let's just print a warning once to show
this potential problem to the user.

374d5d9971 sandbox.dtsi: add a sandbox,alarm-wdt instance

10107efedd sandbox: add SIGALRM-based watchdog device
In order to test that U-Boot actually maintains the watchdog device(s)
during long-running busy-loops, such as those where we wait for the
user to stop autoboot, we need a watchdog device that actually does
something during those loops; we cannot test that behaviour via the DM
test framework.

So introduce a relatively simple watchdog device which is simply based
on calling the host OS' alarm() function; that has the nice property
that a new call to alarm() simply sets a new deadline, and alarm(0)
cancels any existing alarm. These properties are precisely what we
need to implement start/reset/stop. We install our own handler so that
we get a known message printed if and when the watchdog fires, and by
just invoking that handler directly, we get expire_now for free.

The actual calls to the various OS functions (alarm, signal, raise)
need to be done in os.c, and since the driver code cannot get access
to the values of SIGALRM or SIG_DFL (that would require including a
host header, and that's only os.c which can do that), we cannot simply
do trivial wrappers for signal() and raise(), but instead create
specialized functions just for use by this driver.

Apart from enabling this driver for sandbox{,64}_defconfig, also
enable the wdt command which was useful for hand-testing this new
driver (especially with running u-boot under strace).

2783670583 watchdog: introduce a u-boot,autostart property
This is a companion to u-boot,noautostart. If one has a single
watchdog device that one does want to have auto-started, but several
others that one doesn't, the only way currently is to set the
CONFIG_WATCHDOG_AUTOSTART and then use the opt-out for the majority.

The main motivation for this is to add an autostarted watchdog device
to the sandbox (to test a fix) without having to set AUTOSTART in
sandbox_defconfig and add the noautostart property to the existing
devices. But it's also nice for symmetry, and the logic in
init_watchdog_dev() becomes simpler to read because we avoid all the
negations.

Eliminate the below smatch warning:
drivers/mmc/mmc.c:3118 mmc_init_device()
warn: variable dereferenced before check 'm' (see line 3116)

7ff2f30b63 mmc: dwmmc: only clear handled interrupts
Unconditionally clearing DTO when RXDR is set leads to spurious timeouts
in FIFO mode transfers if events occur in the following order:

	mask = dwmci_readl(host, DWMCI_RINTSTS);

	// Hardware asserts DWMCI_INTMSK_DTO here

	dwmci_writel(host, DWMCI_RINTSTS, DWMCI_INTMSK_DTO);

	if (mask & DWMCI_INTMSK_DTO) {
		// Unreachable as DTO is cleared without being handled!
		return 0;
	}

Only clear interrupts that we have seen and are handling so that DTO is
not missed.

359c176de5 mmc: stm32_sdmmc2: manage vqmmc
The SDMMC IOs can be in an IO domain, that has to be enabled.
This is done by enabling vqmmc in the driver.
This has no impact on configurations not using an IO domain, the check
can then be executed on all platforms managing regulator, and the vqmmc
regulator enabled on all platforms having it in their DT.

27fbce4326 mmc: stm32_sdmmc2: protect against unsupported modes
The UHS modes for SD, HS200 and HS400 modes for eMMC are not supported
by the stm32_sdmmc2 driver.
Make it clear by removing the corresponding caps after parsing the DT.

be1872982e mmc: stm32_sdmmc2: add dual data rate support
To support dual data rate with STM32 sdmmc2 driver, the dedicated bit
(DDR - BIT(18)) needs to be set in the CLKRC register. Clock bypass
(no divider) is not allowed in this case. This is required for the
eMMC DDR modes.
