[PATCH v2 0/3] arm64: Large PIE fixes

[Edgar E. Iglesias <edgar.iglesias@gmail.com>]

From: "Edgar E. Iglesias" <edgar.iglesias@xilinx.com>

This fixes some builds issues with large (> 1MB) PIE U-boot setups.
We also document the 4K aligned load address requirement and
add an early run-time check for it.

Thanks,
Edgar

ChangeLog:
v1 -> v2:
* Fix adr of _start in arch/arm/lib/crt0_64.S
* Add early check and bail out into a WFI loop when not 4K aligned
* Document the 4K alignement requirement in Kconfig

Edgar E. Iglesias (3):
  arm64: Mention 4K aligned load addresses in the PIE Kconfig help
  arm64: Bail out PIE builds early if load address is not 4K aligned
  arm64: Add support for larger PIE U-boot
