i2c: Create a new Kconfig for I2C
At present we have CONFIG_SPL_I2C but not CONFIG_I2C. The reason
CONFIG_I2C is not strictly necessary is that:
a) We have CONFIG_SYS_I2C_LEGACY and CONFIG_DM_I2C for the two possible
i2c stacks
b) In U-Boot proper, we always build drivers/i2c/ regardless of the
options
Still, it is better to have CONFIG_I2C - it makes U-Boot proper similar to
SPL/TPL, so we can (in a future commit) simplify the Makefile rules.
Enable it by default, since as above, we have separate options
(SYS_I2C_LEGACY and DM_I2C) to control whether it is 'really' enabled.
Once we have migrated I2C to driver model, we can drop SYS_I2C_LEGACY and
make DM_I2C become I2C. For now, this lets us simplify the Makefile rules.

serial: serial_msm: Delay initialization to let pins stabilize
For some reason, the DragonBoard 410c aborts autoboot immediately if
U-Boot is started without LK. It looks like it picks up a single broken
character via serial and therefore believes a key was pressed to abort
autoboot.
After some debugging, it seems like adding some delay after pinctrl
setup but before UART initialization fixes the issue. It's also worth
mentioning that unlike when booting from LK, the pinctrl setup is
actually necessary when booting U-Boot without LK since UART is broken
if the pinctrl line is removed.
I suspect that reconfiguring the pins might take some time to stabilize
and if the UART controller is enabled too quickly it will pick up some
random noise. Adding a few milliseconds of delay fixes the issue and
shouldn't have any other negative side effects.
3ms seems to be the minimum delay required in my tests, use 5ms instead
just to be sure.

board: dragonboard410c: Fix fastboot
At the moment pressing the volume down key does not actually launch

disables autoboot and drops to the U-Boot console. It does not execute
the "bootcmd".
The correct value for "bootdelay" here would be "-2", which disables
the delay and key checking and would immediately execute the "bootcmd".
However, even better in this case is using "preboot" to trigger Fastboot.
The advantage is that running "fastboot continue" will actually continue
the autoboot process instead of ending up in the U-Boot shell.
Also make sure to unset "preboot" again immediately in case the user
saves the environment after triggering fastboot.

board: dragonboard410c: Load U-Boot directly without LK
At the moment the U-Boot port for the DragonBoard 410c is designed
to be loaded as an Android boot image after Qualcomm's Little Kernel (LK)
bootloader. This is simple to set up but LK is redundant in this case,
since everything done by LK can be also done directly by U-Boot.
Dropping LK entirely has at least the following advantages:
- Easier installation/board code (no need for Android boot images)
- (Slightly) faster boot
- Boot directly in 64-bit without a round trip to 32-bit for LK
So far this was not possible yet because of unsolved problems:
1. Signing tool: The firmware expects a "signed" ELF image with extra
(Qualcomm-specific) ELF headers, usually used for secure boot.
The DragonBoard 410c does not have secure boot by default but the
extra ELF headers are still required.
2. PSCI bug: There seems to be a bug in the PSCI implementation
(part of the TrustZone/tz firmware) that causes all other CPU cores
to be started in 32-bit mode if LK is missing in the boot chain.
This causes Linux to hang early during boot.
There is a solution for both problems now:
1. qtestsign (https://github.com/msm8916-mainline/qtestsign)
can be used as a "signing" tool for U-Boot and other firmware.
2. A workaround for the "PSCI bug" is to execute the TZ syscall when
entering U-Boot. That way PSCI is made aware of the 64-bit switch
and starts all other CPU cores in 64-bit mode as well.
Simplify the dragonboard410c board by removing all the extra code that
is only used to build an Android boot image that can be loaded by LK.
This allows dropping the custom linker script, special image magic,
as well as most of the special build/installation instructions.
CONFIG_REMAKE_ELF is used to build a new ELF image that has both U-Boot
and the appended DTB combined. The resulting u-boot.elf can then be
passed to the "signing" tool (e.g. qtestsign).
The PSCI workaround is placed in the "boot0" hook that is enabled
with CONFIG_ENABLE_ARM_SOC_BOOT0_HOOK. The extra check for EL1 allows
compatibility with custom firmware that enters U-Boot in EL2 or EL3,
e.g. qhypstub (https://github.com/msm8916-mainline/qhypstub).
As a first step these changes apply only to DragonBoard410c.
Similar changes could likely also work for the DragonBoard 820c.
Note that removing LK wouldn't be possible that easily without a lot of
work already done three years ago by Ramon Fried. A lot of missing
initialization, pinctrl etc was already added back then even though
it was not strictly needed yet.

Since we can not set OsIndications from Runtime Services

configs: synquacer: Use RAW capsule image instead of FIT
Since the recent commit;
commit
b891ff18f899 ("efi_loader: Force a single FMP instance per hardware store")
forces a single FMP instances for a storage, we can not
enable both RAW and FIT capsule image support at once.
Since RAW capsule image support is simpler than FIT,
enable RAW capsule image instead of FIT by default.

board: synquacer: Initialize SCBM SMMU at board_init()
Since the SCBM SMMU is not only connected to the NETSEC
but also shared with the F_SDH30 (eMMC controller), that
should be initialized at board level instead of NETSEC.
Move the SMMU initialization code into board support
and call it from board_init().
Without this fix, if the NETSEC is disabled, the Linux
eMMC ADMA cause an error because SMMU is not initialized.
