A variety of Qualcomm features/fixes for this cycle, notably with a few
new platforms gaining support:

* Initial support for SDM670 (similar to SDM845), SM6350, and SM7150
  platforms is added
* USB and UART issues on MSM8916 are addressed (improving stability/
  reliability)
* Firmware loading is implemented for the GENI serial engine, this is
  used on some platforms to load firmware for i2c/spi/uart to work

Some additional patches like binman support for building MBN files still
need some additional work.

CI: https://source.denx.de/u-boot/custodians/u-boot-snapdragon/-/commit/8ef6ac07b35e39a57501554680bbf452e818d3e3/pipelines?ref=qcom-main

Qualcomm peripherals like UART, SPI, I2C, etc are all exposed under a
common GENI Serial Engine wrapper device. Replace the stub driver we use
for this currently with a full-on misc device and implement support for
loading peripheral firmware.

Each of the peripherals has it's own protocol-specific firmware, this is
stored on the internal storage of the device with a well-known partition
type GUID.

To support this, GENI will bind peripherals in two stages. First the
ones that already have firmware loaded (such as the serial port) are
bound in the typical way. But devices that require firmware loading are
deferred until EVT_LAST_STAGE_INIT. At this point we can be sure that
the storage device is available, so we load the firmware and then bind
and probe the remaining children.

Child devices are expected to determine if firmware loading is necessary
and call qcom_geni_load_firmware().

Since Linux currently doesn't support loading firmware (and firmware may
not be available), we probe all GENI peripherals to ensure that they
always load firmware if necessary.

This commit introduces a port of the Linux kernel's driver for the
Mediatek's MT7621 I2C controller.

The port was undertaken as the existing driver intended for Mediatek
I2C controllers (mtk_i2c.c) is not compatible with the MT7621.

To use the driver:

  1.  Ensure that the mode of the i2c pin group is
      configured for "i2c" rather than "gpio".

  2.  Delete the existing (bitbanged) i2c node from
      arch/mips/dts/mt7621.dtsi, or specify:

        /delete-node/ &i2c;

  3.  Declare:

        i2c: i2c@1e000900 {
                compatible = "mediatek,mt7621-i2c";
                reg = <0x1e000900 0x100>;

                clocks = <&clk50m>;
                clock-names = "sys_clock";

                resets = <&rstctrl RST_I2C>;
                reset-names = "i2c_reset";

                pinctrl-names = "default";
                pinctrl-0 = <&i2c_pins>;

                #address-cells = <1>;
                #size-cells = <0>;
                status = "okay";
        };

A few i2c drivers cannot build without access to some platform specific
header files. Express those requirements in Kconfig as well.

Signed-off-by: Tom Rini <trini@konsulko.com>

We have a few options that we cannot enable in a "allyesconfig" type
build because we cannot use zero as a default value.

- The logic around HAS_BOARD_SIZE_LIMIT assumes that if we have set this
  then we compare with it. Similarly, we need to set SPL_NO_BSS_LIMIT as
  the default there.
- Both SYS_CUSTOM_LDSCRIPT and ENV_USE_DEFAULT_ENV_TEXT_FILE then prompt
  for a file name to use.
- The SYS_I2C_SOFT driver is a legacy driver which requires a lot of
  configuration within the board config. file instead, so disable it.

Add a Kconfig option to disable sending Stop conditions between multiple
i2c_msgs within a single xfer. Enable this config by default for ARCH_K3
platforms.

Newer Samsung SoCs (including newer Exynos, ExynosAuto, Google Tensor)
still use these IPs, or slightly newer versions of it.

Make these drivers available on these platforms by guarding
EXYNOS4/EXYNOS5 specific code behind their configs, and using CCF for
clocks on other platforms.

Tested S3C I2C driver on Exynos7885.
This along with extended clock driver should enable S3C I2C on
Exynos850.
