initialize potential uninitialized variable with the type of"char*" to
be NULL in AVB. That "hashtree_error_mode" in code is manually specified
with a known value, the cases listed cover all potential value of
"hashtree_error_mode"explicitly do a type cast for memcpy parameters.

The CONFIG_QSPI_BOOT has been removed from SPL flexspi build, because
we have to change the u-boot ENV to SD/MMC, and this configuration will
set relevant configurations.But we don't clean up CONFIG_QSPI_BOOT for SPL completely, SPL still has
some places using it and cause problem to flexspi boot.
Using CONFIG_SPL_SPI_SUPPORT to replace the CONFIG_QSPI_BOOT.Signed-off-by: Ye Li

SCFW has taken to reset the base board by deasserting BB_PER_RST_B(SCU_GPIO0_01) on
imx8QM MEK board, and has removed the SC_R_BOARD_R1 functionality.
So We don't need to explicitly use SC_R_BOARD_R1, delete the codes from u-boot.Signed-off-by: Ye Li

Write magic number in board early init, and clear magic when booting
Linux.This is to let XEN know the current EL1 code is U-Boot or Linux
when reset/reboot. This is just a workaround because CM41 could not
communicate with XEN now, even XEN knows that EL1 is reseting/rebooting.Signed-off-by: Peng Fan

To support partition reboot, the u-boot has to enable clocks by LPCG.
The LPCG will reset to default value only when the subsystem is totally
power off and reset. However, the resources in one subsystem may belong
to different partitions, so the partition reboot may not reboot the entire
subsystem.
Powers, clocks/lpcg, GPR, IP may not reset depends on various cases and
HW design. Thus, AP software has to ensure everything is reset by SW
itself to support such above cases.Signed-off-by: Ye Li

Because u-boot USB gadget only can support one driver, so if we enable
ci_udc driver, the cdns3 gadget driver must be disabled. This cause build
error because we don't wrap the cdns gadget functions with its configuration.Fix the issue by adding CONFIG_USB_CDNS3_GADGET before cdns3 gadget function.

Add the secure boot relevant environment variables to ARM2 and MEK.
When CONFIG_AHAB_BOOT is enabled, we will switch to boot flow:
1. Load the signed OS container to address 0x88000000
2. Using auth_cntr to authenticate the OS container. It will load the
kernel and FDT to destination addresses.
3. Using booti to boot kernel.Signed-off-by: Ye Li

We are targeting let uboot loading images from emmc to boot android.
Currently only emmc1 is enabled, so other devices are disabled.Also change memory layout according to VM layout. The memory layout
needs to be samesize as what you configured in as "memory = "3584"".Add a new dts dedicated for this kind uboot, add a new defconfig
to select CONFIG_XEN/CONFIG_XEN_DEBUG_SERIAL, deselect CONFIG_DM_SERIAL,
select CONFIG_ENABLE_ARM_SOC_BOOT0_HOOK, and disable some devices

Make sure that all devices that are powered up by uboot
are powered down before bringing up kernel.
Else the subsystem/device will never be powered down by SCFW even though
from the kernel's point of view it should be powered down.Benefiting from power domain driver, We have implemented the function "power_off_pd_devices"
to power off all active devices. No need to explicitly power off them in board_quiesce_devices.Signed-off-by: Ranjani Vaidyanathan
