fpga: zynqmp: support loading encrypted bitfiles

2022-07-26T07:34:21Z

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."

cmd: fpga: Change return value to avoid printing usage text

2019-07-30T08:21:16Z

In cmd/fpga.c the commands should return enum command_ret_t, e.g. CMD_RET_USAGE, CMD_RET_SUCCESS, or CMD_RET_FAILURE. What they actually do is passing a return value from different 'fpga_' functions. Passing on a return value of -1 from a called function leads to printing out usage text. In case of actually correct usage with correctly specified parameters but some fail at runtime printing out that usage text is distracting. The reason is most 'fpga_' functions return either FPGA_SUCCESS or FPGA_FAIL, the latter was equal to -1 which is the same value as CMD_RET_USAGE. So just passing on FPGA_FAIL lead to printing out usage. We should only return CMD_RET_USAGE in cases, where the user sent wrong input. Every other case should return CMD_RET_SUCCESS or CMD_RET_FAILURE, and not simply pass an error code. Simply changing FPGA_FAIL from -1 to 1 gets the job done.

cmd: fpga: Add support to load secure bitstreams

2018-06-01T09:37:31Z

This patch adds support to load secure bitstreams(authenticated or encrypted or both). As of now, this feature is added and tested only for xilinx bitstreams and the secure bitstream was generated using xilinx bootgen tool, but the command is defined in more generic way. Command example to load authenticated and device key encrypted bitstream is as follows "fpga loads 0 100000 2000000 0 1" Signed-off-by: Siva Durga Prasad Paladugu Signed-off-by: Michal Simek

SPDX: Convert all of our single license tags to Linux Kernel style

2018-05-07T13:34:12Z

When U-Boot started using SPDX tags we were among the early adopters and there weren't a lot of other examples to borrow from. So we picked the area of the file that usually had a full license text and replaced it with an appropriate SPDX-License-Identifier: entry. Since then, the Linux Kernel has adopted SPDX tags and they place it as the very first line in a file (except where shebangs are used, then it's second line) and with slightly different comment styles than us. In part due to community overlap, in part due to better tag visibility and in part for other minor reasons, switch over to that style. This commit changes all instances where we have a single declared license in the tag as both the before and after are identical in tag contents. There's also a few places where I found we did not have a tag and have introduced one. Signed-off-by: Tom Rini

fpga: allow programming fpga from FIT image for all FPGA drivers

2017-12-14T15:09:39Z

This drops the limit that fpga is only loaded from FIT images for Xilinx. This is done by moving the 'partial' check from 'common/image.c' to 'drivers/fpga/xilinx.c' (the only driver supporting partial images yet) and supplies a weak default implementation in 'drivers/fpga/fpga.c'.
