[U-Boot] [PATCH v1 0/5] Enable PPA in SPL for ARMv8 Layerscape SoCs

[York Sun]

This is the first step to move NXP Layerscape SoCs to run at EL2.
With PPA (an implementation of trusted firmware) loaded during
SPL stage, the rest of U-Boot (and subsequently loaded RAM version)
runs at EL2. Eventually non-SPL boot will also moves to this
direction.


York Sun (5):
  armv8: layerscape: Make U-Boot EL2 safe
  armv8: layerscape: Enabling loading PPA during SPL stage
  armv8: ls1043ardb: Enable loading PPA during SPL stage for SD boot
  armv8: ls1046a: Enable spl_board_init() function
  armv8: ls1046ardb: Enable loading PPA during SPL stage for SD boot
