* [PATCH v8 00/14] fpga: zynqmp: Adding support of loading authenticated images @ 2022-05-31 23:08 Oleksandr Suvorov 2022-05-31 23:08 ` [PATCH v8 01/14] Prepare v2022.07-rc3 Oleksandr Suvorov 0 siblings, 1 reply; 15+ messages in thread From: Oleksandr Suvorov @ 2022-05-31 23:08 UTC (permalink / raw) To: u-boot Cc: Michal Simek, Adrian Fiergolski, Ricardo Salveti, Jorge Ramirez-Ortiz, Igor Opaniuk, Oleksandr Suvorov, Alexandru Gagniuc, Artem Lapkin, Ashok Reddy Soma, Heiko Schocher, Heinrich Schuchardt, Leo Yu-Chi Liang, Lokesh Vutla, Masahisa Kojima, Michal Simek, Nishanth Menon, Ovidiu Panait, Simon Glass, Steffen Jaeckel 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 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 v8 14/14] fpga: zynqmp: support loading encrypted bitfiles 2022-05-31 23:08 ` [PATCH v8 13/14] fpga: zynqmp: support loading authenticated images Oleksandr Suvorov @ 2022-05-31 23:08 ` Oleksandr Suvorov 0 siblings, 0 replies; 15+ messages in thread From: Oleksandr Suvorov @ 2022-05-31 23:08 UTC (permalink / raw) To: u-boot Cc: Michal Simek, Adrian Fiergolski, Ricardo Salveti, Jorge Ramirez-Ortiz, Igor Opaniuk, Oleksandr Suvorov, Michal Simek 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 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. doc/uImage.FIT/source_file_format.txt | 2 ++ drivers/fpga/zynqmppl.c | 8 ++++++++ include/fpga.h | 1 + include/xilinx.h | 1 + include/zynqmppl.h | 2 +- 5 files changed, 13 insertions(+), 1 deletion(-) diff --git a/doc/uImage.FIT/source_file_format.txt b/doc/uImage.FIT/source_file_format.txt index 461e2af2a84..68701118409 100644 --- a/doc/uImage.FIT/source_file_format.txt +++ b/doc/uImage.FIT/source_file_format.txt @@ -188,6 +188,8 @@ the '/images' node should have the following layout: "u-boot,fpga-legacy" - the generic fpga loading routine.
