This fixes some build 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.
As requested by reviewers, I've also added a runtime check for non-PIE builds to trap the startup sequence early if the start address doesn't match between run-time and link-time.
Cheers, Edgar
ChangeLog: v2 -> v3:
- Add non-PIE start address (run vs link-time) check
- Move 4K aligment Kconfig help description
- Fix load of __bss_start
- Use x0 rather than x1 in PIE load-address check
- Add missing tabs
- Add load-address check for non-PIE
- U-boot -> U-Boot in a few places
- Tweak commit messages
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

Because these changes are made for supporting Xilinx SOCs 1-3 applied to my tree. Patch 4 is dropped as was agreed.
Thanks, Michal
