12e07033c7 rockchip: rk3308: Enable ARMv8 crypto and FIT checksum validation
The RK3308 SoC support ARMv8 Cryptography Extensions and use of the
ARMv8 crypto extensions help speed up FIT checksum validation in SPL.

Imply ARMV8_SET_SMPEN and ARMV8_CRYPTO to take advantage of the crypto
extensions for SHA256 when validating checksum of FIT images.

Imply SPL_FIT_SIGNATURE and LEGACY_IMAGE_FORMAT to enable FIT checksum
validation on all RK3308 boards.

Also disable CONFIG_SPL_RAW_IMAGE_SUPPORT in board defconfigs to ensure
SPL does not try to jump to code that failed checksum validation.

50ac349d0b rockchip: spl-boot-order: show DT path for missing device
When debugging the SPL boot order, the node ID of a device which hasn't
been found is printed but it can be quite hard to relate that to the
specific devicetree node. To aid debugging, print the node path instead of
the cryptic node ID.

Original debug message:

    board_boot_order: could not map node @73c to a boot-device

With this patch applied this becomes e.g:

   board_boot_order: could not map node /spi@ff1d0000/flash@0 to a boot-device

73d7210791 rockchip: ringneck-px30: put STM32_RST line in input mode instead of output
The STM32_RST line is routed to the ATtiny microcontroller
PA0/RESET/UPDI pin. By driving the PX30 SoC pin as GPIO output high, we
prevent external UPDI to be used for flashing without first putting this
pin as GPIO input, an extra step we could avoid in userspace.

There's an external hardware pull-up strong enough to keep the STM32_RST
state high on ATtiny side but weak enough it can be overridden by
external UPDI. This also means it is safe to use for the STM32 variant,
where STM32_RST line will be in the same state as if output high was
used.

The Q7 standard specifies that MFG_NC1 and MFG_NC2 (used for UPDI for
Ringneck) pins should neither be driven by the carrierboard, nor have
pull-up or pull-down resistors. This means this commit is safe to use
regardless of the carrierboard this module would be connected to
(provided it follows the Q7 standard).

a7e69952eb rockchip: spl: Cache boot source id for later use
Rockchip BROM writes a boot source id at CFG_IRAM_BASE + 0x10, this id
indicates from what storage media TPL/SPL was loaded from.

SPL uses this id to determine what device "same-as-spl" represent when
determining from where FIT should be loaded. This works as long as the
boot_devices array contain a matching id <-> node path entry.

However, SPL typically load a small part of TF-A into SRAM and on RK3399
this overwrites the CFG_IRAM_BASE + 0x10 addr used for boot source id.

For affected devices the u-boot,spl-boot-device would not be set when
booting from SPI flash and the flash@0 node was not explicitly listed
in the u-boot,spl-boot-order prop.

Here boot source id is 3 before FIT images is loaded, and 0 after:

  U-Boot SPL 2024.04-rc4 (Mar 15 2024 - 17:26:19 +0000)

  spl_decode_boot_device: could not find udevice for /mmc@fe320000
  spl_perform_fixups: could not map boot_device to ofpath: -19

Use a static brom_bootsource_id_cache to save the boot source id after
an initial read from SRAM to fix this, this allow spl_perform_fixups()
to resolve correct boot source path for "same-as-spl" after SPL have
loaded TF-A related FIT images into memory.

With this the spl-boot-device prop can correctly be resolved to the
SPI flash node in the control FDT:

  => fdt addr ${fdtcontroladdr}
  Working FDT set to f1ee6710
  => fdt list /chosen
  chosen {
      u-boot,spl-boot-device = "/spi@ff1d0000/flash@0";

  Initial support includes buttons and USB (host and gadget).
* SM8250 is a flagship SoC from 2020 used on the RB5, as well as many flagship

  necessary for USB support.
* SM8550, and SM8650 are flagship mobile SoCs from 2023 and 2024

In addition:

* Support is added for the Schneider HMIBSC board.
* mach-snapdragon switches to OF_UPSTREAM
* IPQ40xx gets several regressions fixed and some overall cleanup.
* The MSM serial driver gains the ability to generate the bit-clock
  automatically, no longer relying on a custom DT property.
* The Qualcomm SMMU driver gets a generic compatible (so per-SoC compatibles
  don't need to be added).
* Support for the GENI I2C controller is added.
* The qcom SPMI driver has SPMI v5 support fixed, and v7 support added.
* The qcom sdhci driver gets some fixes for SDCC v5 support.
* SDM845 gains sdcard support
* Support is added for the Synopsys eUSB2 PHY driver (used on SM8550 and SM8650)
* SYS_INIT_SP_BSS_OFFSET is set to 1.5M to give us more space for FDTs.

based on system configuration.

It also supports the "I2C Master Hub" which is a single function Wrapper
that only FIFO mode I2C.

It replaces the fixed-function QUP Wrapper found on older SoCs.

The geni-se.h containing the generic GENI Serial Engine registers defines
is imported from Linux.

8c4c6a268e pinctrl: qcom: ipq4019: support all pin functions
Currently, IPQ4019 pinctrl driver supports only a very limited number of
pin functions and is not fully DT compatible with Linux pinctrl nodes.

IPQ40xx SoC-s sometimes use different pin function numbers for the same
function depending on the pin number, so for example I2C0 on GPIO58 uses
function number 3 while on GPIO59 it uses function number 2.

So, in order to make the driver compatible with upstream DTS to avoid the
need to patch the pinctrl nodes in U-Boot and support all of the missing
pin functions lets rework the driver based on upstream Linux IPQ4019
pinctrl driver and the pending SM8150 U-Boot pinctrl driver which also uses
different function numbers pased on the exact pin number.

This is due to the fact that IPQ4019 pinctrl driver is not available prior
to relocation and thus MSM serial will fail probing as pinctrl provider is
not available.

So, lets enable DM_FLAG_PRE_RELOC for IPQ4019 pinctrl to fix this.

69e9b3428b serial: msm: calculate bit clock divider
The driver currently requires the bit clock divider be hardcoded in
devicetree (or use the hardcoded default from apq8016).

The bit clock divider is used to derive the baud rate from the core
clock:

  baudrate = clk_rate / csr_div

clk_rate is the actual programmed core clock rate which is returned by
clk_set_rate(), and this UART driver only supports a baudrate of 115200.
We can therefore determine the appropriate value for UARTDM_CSR by
iterating over the possible values and finding the one where the
equation above holds true for a baudrate of 115200.

Implement this logic and drop the non-standard DT bindings for this
driver.

Tested on dragonboard410c.

99e791746f clk/qcom: ipq4019: return valid rate when setting UART clock
clk_set_rate() should return the clock rate that was set. The IPQ4019
clock driver doesn't set any rates yet but it should still return the
expected value so that drivers can work properly.

For a baud rate of 115200 with an expected bit clock divisor of 16, the
clock rate should be 1843200 so return that frequency.

8a4e043305 clk/qcom: apq8016: return valid rate when setting UART clock
The clk_init_uart() helper always returns 0, but we're meant to return a
real clock rate. Given that we hardcode 115200 baud, just return the
clock rate that we set.

615a3e909e serial: msm_serial: remove .clk_rate from debug UART
MSM serial in DEBUG UART mode is trying to set .clk_rate, but the
msm_serial_data structure does not have such property at all, so lets
remove it as otherwise it will fail compiling.

6b163a63e5 serial: allow selecting MSM debug UART with ARCH_IPQ40XX
Currently, DEBUG_UART_MSM depends on ARCH_SNAPDRAGON only, but IPQ40XX
devices also use the same UART HW so they can also use the debug UART.

So, allow selecting DEBUG_UART_MSM when using ARCH_IPQ40XX as well.
