[PATCH v2 00/21] Enable ARM Trusted Firmware for U-Boot

[chee.hong.ang at intel.com]

From: "Ang, Chee Hong" <chee.hong.ang at intel.com>

v2 changes:

- Default defconfig support SPL + ATF + U-Boot boot flow:
  (socfpga_stratix10_defconfig / socfpga_agilex_defconfig)
  
  SPL (EL3) -> ATF-BL31 (EL3) -> U-Boot Proper (EL2) -> Linux (EL1)

  Added new defconfig to support existing SPL + U-Boot (no ATF) boot flow:
  (socfpga_stratix10_nofw_defconfig / socfpga_agilex_nofw_defconfig)

  SPL (EL3) -> U-Boot Proper (EL3) -> Linux (EL1)


- SMC/PSCI calls (EL2) / secure code (EL3) is built in compile time

- Mailbox/FPGA reconfiguration driver now support ATF or without ATF
