arm64: renesas: r8a779g3: Disable dual-rank DRAM on Retronix R-Car V4H ES2 Sparrow Hawk
The R-Car V4H SoC before rev.3.0 can not support dual-rank LPDDR5 DRAM.
This affects 16 GiB dual-rank DRAM configuration of Retronix R-Car V4H

on such systems instead.
Signed-off-by: Marek Vasut <marek.vasut+renesas@mailbox.org>
The Retronix R-Car V4H Sparrow Hawk old revision EVTA1 does not have MicroSD
voltage switch populated on the board, therefore the board supports only 3V3
and non-UHS MicroSD cards. While the EVTB1 board is populated with Winbond
W77Q51NW SPI NOR, the EVTA1 board is populated with Spansion S25FS512S SPI
NOR, those those SPI NOR IDs to discern the two board revisions and apply
the MicroSD related DT changes.
The MicroSD related DT changes modify the regulator node, which is now a
regulator-fixed and supplies only 3V3, and remove sd-uhs-sdr50 and
sd-uhs-sdr104 properties from the MicroSD slot controller node.
The MicroSD related DT changes cannot be applied as DTO, because the base
DT contains nodes which have to be removed in case of EVTA1, but have to
be present in case of EVTB1 and newer revisions of the board. Because the
EVTA1 is an old revision of the board that is not generally available, it
is better to special case it and keep the base DT compatible with EVTB1
and newer revisions of the board which are actually available.

rockchip: add /chosen/bootsource to U-Boot proper DT
U-Boot typically can be loaded from different storage media, such as
eMMC, SD card, SPI flash, but also from non-persistent media such as USB
(via proprietary protocols loading directly into SRAM, or fastboot, DFU,
etc..), JTAG, ...
This information is usually reported by the BootROM via some proprietary
mechanism (some specific address in registers/DRAM for example). For
Rockchip, that information is stored in a register
(BROM_BOOTSOURCE_ID_ADDR).
While we already have the information about which medium was used to
load U-Boot proper from SPL (via /chosen/u-boot,spl-boot-device), this
new property represents the medium used to load U-Boot first phase
(depending on configuration, can be VPL/TPL/SPL) which absolutely may
differ from the one used to load U-Boot proper!
It would be useful to know which medium was used to load the first phase
of U-Boot, for example to check fallback mechanisms (proper loaded from
a different medium than first phase) are actually working.
For now, this only applies to Rockchip's U-Boot proper DT but could be
applied to the kernel's as well and possibly for other architectures or

The JEDEC LPDDR3 spec defines mode register 0 (MR0) as being read-only,
so there is no point in trying to set its value.
Also the H616 memory controller encodes the mode register index to be
written starting from bit 8 in MRCTRL1 (for LPDDR3 and LPDDR4 chips), so
we need to OR in that number to tell the controller which MR to program.
On top of that, the mode registers between DDR3 and LPDDR3 are
completely different, so writing values crafted for DDR3 into a LPDDR3
chip is just wrong. Due to the above mentioned bugs the writes for
MR0-MR2 did not have any effect (as they were all trying to set the
read-only MR0), so the mode registers just stayed unchanged.
Looking at the LPDDR3 spec and the BSP code, let's write the proper MR
values into LPDDR3 chips, using the proper addressing mode.
Use the opportunity to document the LPDDR3 mode register bits written.

functions as we do not need them or mappings to existing functions,
similar to how other architectures handle it.
board: phytec: phycore-am64x: Add watchdog start to bootcmd
Allows run-time control over watchdog auto-start and the timeout via
setting the environment variable watchdog_timeout_ms. A value of zero
means "do not start". Use CONFIG_WATCHDOG_TIMEOUT_MSECS as initial value.
Users can enable the watchdog to monitor the boot process until userspace
or OS takes over to serve the watchdog.
We switched towards standard boot with still keeping a fallback
using legacy boot command alive. Add a deprecation warning to
make it more clear that we will remove it in future versions.

arch: arm: dts: k3-am642-phyboard-electra: Disable unused watchdogs in U-Boot
The watchdog driver probes all available watchdog devices.
This causes SMP boot errors when bringing up secondary CPUs.
In our setup, only a single watchdog is needed to monitor the
boot process until userspace or the OS takes over. Disable all
unnecessary watchdog devices in U-Boot to avoid conflicts
during CPU bring-up.
