[v4 00/17] Enable ARM Trusted Firmware for U-Boot

[Siew Chin Lim]

This is the 4th version of patchset to enable ARM Trusted Firmware
for U-Boot for Intel Stratix10 and Agilex platform.

New U-boot flow with ARM Trusted Firmware (ATF) support:
SPL (EL3) -> ATF-BL31 (EL3) -> U-Boot Proper (EL2) -> Linux (EL1)

SPL loads the u-boot.itb which consist of:
1) u-boot-nodtb.bin (U-Boot Proper image)
2) u-boot.dtb (U-Boot Proper DTB)
3) bl31.bin (ATF-BL31 image)


Patch status:
Have changes: Patch 7, 8, 9, 16
Other patches unchanged.

Detail changelog can find in commit message.

v3->v4:
--------
Patch 7:
-  Add secure register access helper functions for SoC 64bits
   These secure register access functions allow U-Boot proper running
   at EL2 (non-secure) to access System Manager's secure registers
   by calling the ATF's PSCI runtime services (EL3/secure).

Patch 8:
-  Call secure register access helper function to set
   SDMMC's DRVSEL and SMPLSEL.

Patch 9:
-  Call secure register access helper function to setup
   the PHY interface.

patch 16:
-  Adjust BINMAN sequence in code, sorted by alphabetical order.
   No change on functionality.
