[PATCH v3 0/3] fpga: zynqmp: Adding support of loading authenticated images

[Oleksandr Suvorov]

This patchset introduces support for the authenticated FPGA images
on ZynqMP boards, besides that introducing common way to pass the
compatible property to any fpga driver.

It bases on the initial work by Jorge Ramirez-Ortiz <jorge at foundries.io>
https://patchwork.ozlabs.org/project/uboot/patch/20211015091506.2602-1-jorge@foundries.io/
https://patchwork.ozlabs.org/project/uboot/patch/20211005111324.19749-3-jorge@foundries.io/

Changes in v3:
- remove the patch which introduced CMD_SPL_FPGA_LOAD_SECURE.
- fix mixing definitions/declarations.
- replace strcmp() calls with more secure strncmp().
- document the "u-boot,zynqmp-fpga-ddrauth" compatible string.
- fix code style by check-patch recommendations.

Changes in v2:
- add function fit_fpga_load() to simplify calls of fpga_load()
  from contexts without a compatible attribute.
- move all ZynqMP-specific logic to drivers/fpga/zynqmppl.c
- prepare for passing a "compatible" FDT property to any fpga driver.

Oleksandr Suvorov (3):
  fpga: add option for loading FPGA secure bitstreams
  fpga: add fit_fpga_load function
  fpga: zynqmp: support loading authenticated images
