c18ead4ba7 Merge branch 'master' of https://source.denx.de/u-boot/custodians/u-boot-sunxi
Not many and nothing really exciting this time: there are more patches
in fly, but they are not ready yet.  I will also send some DT updates
and new board defconfig files later, once they have seen the list. I am
aware of the USB rebasing repo efforts, but would like to see how this
plays out, also we have one compatibility issue that I painstakingly
work around in the U-Boot tree for the last three years or so. So for
now I stick to the previous approach.

So now just some easy changes: support for USB peripheral mode on the
Allwinner F1C100s, T113-s3 SPI boot support, and some SPL cleanup
patches.

The branch passed the gitlab CI run, and brief boot testing on some
boards didn't turn up any issues.

Of all T30 transformers, only the TF700T has a FullHD DSI panel,
which is connected via tc358768 RGB to DSI bridge. Since the
bridge driver is available now, TF700T can have video support.

192c5c9e51 sunxi: sun9i: make more clock functions SPL only
In clock_sun9i.c, responsible for (mostly early) clock setup on the
Allwinner A80 SoC, many functions are only needed by the SPL, and are
thus already guarded by CONFIG_SPL_BUILD.

Over the years drivers like for the UART or I2C were converted to DM, and
they care about clock setup themselves now, by using a proper DM clock
driver.

This means those devices need the clock setup functions here for the SPL
only. Move some functions around, to group all SPL-only function within
one #ifdef guard. Some functions were exported, but never used outside
of this file, so remove their prototypes from the header file and mark
them as static.

This avoids unnecessary code in U-Boot proper and helps further
refactoring. Add some comments on the way to help understanding of the
file.

8cb3c49454 sunxi: compile clock.c for SPL only
With the clock_twi_onoff() function now being called only from the SPL,
the whole clock.c file in arch/arm/mach-sunxi is needed by SPL code
only.

Remove the redundant #ifdef from the clock_init() function, actually
this function was already only called from the SPL.
Then adjust the Makefile to compile clock.c only with CONFIG_SPL_BUILD
defined.

This avoids unnecessary code in U-Boot proper and allows further
refactoring and code-split between the SPL and U-Boot proper.

02780a1c26 sunxi: move #ifdef guards around tzpc_init() to header file
Some later 32-bit SoCs require some setup of the Secure Peripherals
Controller, which is handled in tzpc_init().
At the moment this is guarded in board.c by some #ifdefs selecting the
SoCs that need it.

Move those #ifdef guards into the header file, providing an empty stub
function for all other SoCs, so that the #ifdefs can be removed from the
.c file, to improve readability.

83d5e3c9e9 sunxi: SPL SPI: Add SPI boot support for the Allwinner R528/T113 SoCs
R528/T113 SoCs uses the same SPI IP as the H6, also have the same clocks
and reset bits layout, but the CCU base is different. Another difference
is that the new SoCs do not have a clock divider inside. Instead of this
we should configure sample mode depending on input clock rate.

The pin assignment is also different: the H6 uses PC0, the R528/T113 PC4
instead. This makes for a change in spi0_pinmux_setup() routine.

This patch extends the H6/H616 #ifdef guards to also cover the R528/T113,
using the shared CONFIG_SUNXI_GEN_NCAT2 and CONFIG_MACH_SUN8I_R528
symbols. Also use CONFIG_SUNXI_GEN_NCAT2 symbol for the Kconfig
dependency.

45d14c0120 arm: dts: verdin-imx8mm/imx8mp: use gpio-hog for sleep moci
In Linux, we allow sleep moci to be turned off when the carrier board
supports it and the system is in suspend. In U-Boot, however, we want
the sleep moci to be always on. So we use a gpio hog and disable the
regulator. This change is necessary because we switched to upstream
device tree files with commit 23fe2def1edf
("verdin-imx8mm/verdin-imx8mp: move imx verdins to OF_UPSTREAM"). A
recent upstream patch removes the gpio hog from the Linux device tree,
so we need to add it to the u-boot dtsi. The following patch will remove
the gpio hog from the Linux device tree:
https://lore.kernel.org/linux-devicetree/20240405160720.5977-1-eichest@gmail.com/
The U-Boot patch can be applied without it and will not break the build.

1ca33cbfd9 ARM: dts: stm32: Update red led node for stm32mp157a-dk1-scmi-u-boot
As indicated in kernel led dt-bindings, label is a deprecated
property, so remove it and use red led node's name instead
for u-boot,error-led property.
Rename "red" led node's name to "led-red".
Remove status property which is useless.

72ff88ecf5 ARM: dts: stm32: Don't probe red led at boot for stm32mp157a-dk1-scmi-u-boot
red led and button dedicated to fastboot share the same gpio GPIOA13.
Led driver is probed early so the corresponding gpio is taken and
configured in output which forbid fastboot and stm32prog button usage.

To avoid this, remove the "default-state" property from red led node.

This will avoid to trigger the led driver probe() to configure the led
default state during startup.

73f7fc944c ARM: stm32: Initialize TAMP_SMCR BKP..PROT fields on STM32MP15xx
In case of an OTP-CLOSED STM32MP15xx system, the CPU core 1 cannot be
released from endless loop in BootROM only by populating TAMP BKPxR 4
and 5 with magic and branch address and sending SGI0 interrupt from
core 0 to core 1 twice. TAMP_SMCR BKP..PROT fields must be initialized
as well to release the core 1 from endless loop during the second SGI0
handling on core 1. Initialize TAMP_SMCR to protect the first 32 backup
registers, the ones which contain the core 1 magic, branch address and
boot information.

This requirement seems to be undocumented, therefore it was necessary
to trace and analyze the STM32MP15xx BootROM using OpenOCD and objdump.
Ultimately, it turns out that a certain BootROM function reads out the
TAMP_SMCR register and tests whether the BKP..PROT fields are non-zero.
If they are zero, the BootROM code again waits for SGI0 using WFI, else
the execution moves forward until it reaches handoff to the TAMP BKPxR 5
branch address.

This fixes CPU core 1 release using U-Boot PSCI implementation on an
OTP-CLOSED system, i.e. system with fuse 0 bit 6 set.
