[U-Boot] [PATCH v3 0/3] efi_loader: ARM: add support for ARMV7_NONSEC=y

[Mark Kettenis]

This series makes it possible to run EFI applications in non-secure
mode.  It allows me to run OpenBSD on the Technexion PICO-PI-IMX7 and
Banana Pi boards using the PSCI implementation provided by U-Boot.

The second version avoids using r3 to pass the original stack pointer.
For some reason that register gets clobbered on the Banana Pi.  Instead
this version just migrates SP_svc to SP_hyp.

This third version avoids saving r3 on the stack and fixes an include
guard as suggested by Alexander Graf.

Mark Kettenis (3):
  ARM: HYP/non-sec: migrate stack
  efi_loader: ARM: run EFI payloads non-secure
  Revert "efi_loader: no support for ARMV7_NONSEC=y"
