JTAG, the ipg_clk, ipg_s_clk, and perclk uses one register as the standard

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

Each module may have one or more lpcg registers for SW/HW enabling its

When moving to support partition reboot or android auto on XEN,
linux kernel will runs into runtime suspend state, and the usb
will be configured to low power suspend state by Linux.Then we reboot and runs into U-Boot, however the usb already in

after clearing PHCD to out of suspended state, the phy pll could be
locked and fastboot works.Signed-off-by: Peng Fan

Because the ROM info on iMX7D does not set device type to USB when booting
from serial download mode, we have to use the mechanism on mx6 to implement

The SPL loads the FIT image FDT part to an address related with the device
block length. This length is 512 for SD/MMC and is 1 for other devices
like SDP, NOR, NAND, SPI, etc.
When signing FIT image, we use fixed address caculated by SD/MMC block length
to sign FDT part. Thus, when booting through uuu, this causes mismatch and
gets authentication failed.Fix the issue by providing a override function for this FIT buffer address.
When secure boot is enabled, adjust the addresses of other devices to be same
with SD/MMC.Signed-off-by: Ye Li

first, if its authentication is failed, the flow continues to load and parse
