arm: mach-k3: j721e: Move booting of Main R5FSS Core0 to A72 U-Boot

The Main R5FSS Core0 on J721E SoCs is originally booted from R5 SPL
itself to achieve certain product-level early-boot metrics. This is
no longer supported after the R5 SPL re-architecture (support merged
for v2021.10-rc1). Move the booting of this core altogether from R5
SPL to A72 U-Boot.

The env variables are left as is for now, and will be cleaned up
in a subsequent patch.

arm: dts: k3-am65: Fix up MCU R5FSS cluster mode back to Split-mode

The default U-Boot environment variables and design are all set up to
have the MCU R5FSS cluster to be in Split-mode. This is the setting
in v2021.01 U-Boot and the dt nodes are synched with the kernel binding
property names in commit 468ec2f3ef8f ("remoteproc: k3_r5: Sync to
upstreamed kernel DT property names") merged in v2021.04-rc2.

The mode for the cluster got switched back to LockStep mode by mistake
in commit e49787634312 ("arm: dts: k3-am65: Sync Linux v5.11-rc6 dts
into U-Boot") also in v2021.04-rc2. This throws the following warning
messages when early-booting the cores using default env variables,

  k3_r5f_rproc r5f@41400000: Invalid op: Trying to start secondary core 2 in lockstep mode
  Load Remote Processor 1 with data@addr=0x82000000 65268 bytes: Failed!

Fix this by switching back the cluster to the expected Split-mode.
Make this mode change in the u-boot specific dtsi file to avoid such
sync overrides in the future until the kernel dts is also switched to
Split-mode by default.

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.

smbios: Fix calculating BIOS Release Date

U-Boot currently sets BIOS Release Date from U_BOOT_DMI_DATE macro which is

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.

1990 cannot support features invented in 2000). So this change also ensures
that recompiling U-Boot from same sources but in different year does not

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.

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 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.

2 years agoboard: dragonboard410c: Load U-Boot directly without LK

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.

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.
