phy: cadence: Add driver for Sierra PHY
Add a Sierra PHY driver with PCIe and USB support.
This driver is a port from the mainline linux driver.
The PHY has multiple lanes, which can be configured into
groups, and a generic PHY device is created for each group.
There are two resets controlling the overall PHY block, one
to enable the APB interface for programming registers, and
another to enable the PHY itself. Additionally there are
resets for each PHY lane.
The PHY can be configured in hardware to read register
settings from ROM, or they can be written by the driver.
The sequence of operation on startup is to enable the APB
bus, write the PHY registers (if required) for each lane
group, and then enable the PHY. Each group of lanes
can then be individually controlled using the power_on()/
power_off() function for that generic PHY
One difference with the linux driver is that the PHY is
always reset after it is powered-on. This is because role
switching is not supported in u-boot and the cable
orientation is handled by the PHY reset.

Fix this issue by setting U_BOOT_DMI_DATE macro to U-Boot version which is
better approximation of U-Boot release date than current build timestamp.
Current U-Boot versioning is in format yyyy.mm so as a day choose 01.
Some operating systems are using BIOS Release Date for detecting when was
SMBIOS table filled or if it could support some feature (e.g. BIOS from

armv8: Initialize CNTFRQ if at highest exception level
CNTFRQ_EL0 is only writable from the highest supported exception
level on the platform. For Armv8-A, this is typically EL3, but
technically EL2 and EL3 are optional so it may need to be
initialized at EL2 or EL1. For Armv8-R, the highest exception
level is always EL2.
This patch moves the initialization outside of the switch_el
block and uses a new macro branch_if_not_highest_el which
dynamically detects whether it is at the highest supported
exception level.
Linux's docs state that CNTFRQ_EL0 should be initialized by the
bootloader. If not set, the the U-Boot prompt countdown hangs.

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
fastboot. This is because setting "bootdelay" to "-1" actually
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: Fix PHYS_SDRAM_1_SIZE
The DragonBoard 410c has proprietary firmware from Qualcomm that
reserves 8 MiB of memory for tz/smem/hyp/rmtfs/rfsa from 0x86000000
to 0x86800000. I'm not aware of any ATF (ARM Trusted Firmware) port
for DB410c that would reserve 30 MiB of memory at the end of RAM.
I suspect the comment might have been copied from hikey.h which has
a very similar comment (and which actually does have an ATF port).
Reducing the memory size just prevents U-Boot from using the end of
the RAM, not the reserved region inbetween. Therefore we might as well
display the correct DRAM size (1 GiB) instead of strange 986 MiB.

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.
