[PATCH v11 00/13] fpga: zynqmp: Adding support of loading authenticated images

[PATCH v11 00/13] fpga: zynqmp: Adding support of loading authenticated images

[Oleksandr Suvorov]

This patchset introduces support for the authenticated and encrypted
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@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 v11:
- Fix treating an incoming FPGA image with empty flags parameter as
  legacy.
- add Tested-by records.

Changes in v10:
- move FPGA flags to macros;
- initialize xilinx_desc structs directly, removing *_DESC macros;
- initialize flags for mach-zynq;
- fix mixed types of return value;
- made the message about ignoring legacy compatibe option as debug
- fix grammar;
- Support DDR images only if FPGA_LOAD_SECURE enabled.
- Support ENC images only if FPGA_LOAD_SECURE enabled.

Changes in v9:
- remove an alien commit from a patchset :)

Changes in v8:
- Michal Simek's suggestions addressed:
-- introduce the compatible flags in xilinx_desc;
-- pass a binary compatible flag instead of "compatible" property to
   an FPGA driver.
- Optimize a zynqmp_load() function.

Changes in v7:
- apply Michal Simek's suggestions
  As I applied changes on Oleksandr's patches, I indicated it by
  specifying myself as co-author in the commits logs. I am not sure
  if that is the convention of marking it.

Changes in v6:
- add support for the encrypted bitfiles.

Changes in v5:
- replace ifdef with if() where it's possible.

Changes in v4:
- change interface to xilinx_desc->operations->open() callback.
- fix a bug from previous version of the patchset in dereferencing
  of a parent fpga_desc structure.

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.

[PATCH v11 02/13] fpga: xilinx: add missed identifier names

[Oleksandr Suvorov]

Function definition arguments should also have identifier names.
Add missed ones to struct xilinx_fpga_op callbacks, unifying code.

[PATCH v11 13/13] fpga: zynqmp: support loading encrypted bitfiles

[Oleksandr Suvorov]

From: Adrian Fiergolski <adrian.fiergolski@fastree3d.com>

Add supporting new compatible string "u-boot,zynqmp-fpga-enc" to
handle loading encrypted bitfiles.

This feature requires encrypted FSBL, as according to UG1085:
"The CSU automatically locks out the AES key, stored in either BBRAM
 or eFUSEs, as a key source to the AES engine if the FSBL is not
 encrypted. This prevents using the BBRAM or eFUSE as the key source
 to the AES engine during run-time applications."

Signed-off-by: Adrian Fiergolski <adrian.fiergolski@fastree3d.com>
Co-developed-by: Oleksandr Suvorov <oleksandr.suvorov@foundries.io>
Signed-off-by: Oleksandr Suvorov <oleksandr.suvorov@foundries.io>

---

Changes in v11:
- add Tested-by records.

Changes in v10:
- Support ENC images only if FPGA_LOAD_SECURE enabled.

Changes in v9:
- remove an alien commit from a patchset :)

Changes in v8:
- Michal Simek's suggestions addressed:
-- introduce the compatible flags in xilinx_desc;
-- pass a binary compatible flag instead of "compatible" property to
   an FPGA driver.
- Optimize a zynqmp_load() function.

Changes in v7:
- apply Michal Simek's suggestions
  As I applied changes on Oleksandr's patches, I indicated it by
  specifying myself as co-author in the commits logs. I am not sure
  if that is the convention of marking it.

Changes in v6:
- add support for the encrypted bitfiles.

Changes in v5:
- replace ifdef with if() where it's possible.

Changes in v4:
- change interface to xilinx_desc->operations->open() callback.
- fix a bug from previous version of the patchset in dereferencing
  of a parent fpga_desc structure.

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.

I have problem with this.
This really matters only when FPGA_LOAD_SECURE is enabled. If this option is not 
enabled there is no reason to call fpga_compatible2flag() because all the time 
it returns only 0 no matter what compatible string is used.

That also mean that in 4/13 and 5/13 you can enable str2flag and 
fpga_compatible2flag only when secure bitstreams are enabled.

  250                 /* If flags is not set, the image treats as legacy */
  251                 flags = FPGA_LEGACY;

Thanks,
Michal

This is unrelated to commit. This is purely coding style change.

This is also coding style change only.

nit: And this also has nothing to do with optimization. You just changed location.

no problem with patchset in general and we are very close. I just want to make 
sure that SPL won't be bigger for cases without enabling SPL_FPGA_LOAD_SECURE.
The reason is very simply which is that we are sharing OCM with TF-A which has 
also size constraints.

Thanks,
Michal

Michal, what is this closer to? Refactor?
It's not only about changing location. Now there is only one call of
xilinx_pm_request().

I know but it s not described in commit message. Diff was really just passing 
different argument. You just change the logic about them where you use clear 
bstype for secure bitstreams and align bsize_req

But you are not changing logic around bsizeptr where old xilfpga expects size to 
be a pointer not value.

Thanks,
Michal

     fpga: zynqmp: Fix the nonsecure bitstream loading issue

     Xilfpga library expects the size of bitstream in a pointer
     but currenly we are passing the size as a value. This patch
     fixes this issue.

This should use driver model, with a UCLASS_FPGA, etc. Can someone
please figure out how to convert it?

We discussed this before and can be done on the top of this series.
