drivers: fpga: intel_sdm_mb: Flush cache before FPGA configuration

2025-06-02T07:13:48Z

FPGA configuration encounters failure when the cache is not flushed. Add cache flushing to the memory region that holds the FPGA configuration bitstream.

arm64: versal2: Add PL bit stream load support

2025-04-16T11:44:44Z

Add support for loading the secure & non-secure pdi images and PL bitstream on the Versal Gen2 platform. The FPGA driver is enabled to load the bitstream in PDI format on the AMD Versal Gen2 device. PDI is the new programmable device image format for Versal Gen2, and the bitstream for the Versal Gen2 platform is generated exclusively in this format. With the enhanced SMC format in TF-A ensuring transparent payload forwarding for Versal Gen2, the u-boot driver must now handle the word swapping of PDI address that was previously done in TF-A for this API. The source code for the Versal2 loadpdi command and the CONFIG_CMD_VERSAL2 configuration has been removed. It now utilizes the fpga load

command to load secure & non-secure pdi images. Signed-off-by: Prasad Kummari Link: https://lore.kernel.org/r/20250327105200.1262615-3-prasad.kummari@amd.com Signed-off-by: Michal Simek

drivers: fpga: Follow mainline to pass compatible flags to fpga_load

2025-04-16T11:42:06Z

Introducing additional flag to check whether an FPGA driver is able to load a particular FPGA bitstream image. Generally, flag variable is used to enable or disable certain features, specify additional parameters (such as error handling), or modify how the function operates. Hence, in this function flags is an integer that can be used to pass configuration options to the fpga_load function. Here, it's initialized to 0, meaning no special options are enabled, but it could modify the flags to influence the function's behavior.

drivers: fpga: Add FPGA configuration during bootm for Intel SOCFPGA

2025-04-16T11:42:06Z

Enabling the capability to automatically perform FPGA configuration when booting Linux FIT image via bootm command. The FPGA configuration bitstream shall be packed within the FIT image. The FPGA data (full or partial) is checked by the SDM hardware, for Intel SDM Mailbox based devices. Hence always return full bitstream. Second function is to enable the HPS to FPGA bridges when FPGA load is completed successfully. This is to ensure the FPGA is accessible by the HPS.

fpga: intel_sdm_mb: add support for query SDM config error and status

2025-01-24T01:56:34Z

Currently the FPGA reconfig status only return a single error status which make the debugging of FPGA reconfiguration hard. This patch is to expose the error status, major error code and minor error code, for the FPGA reconfig to upper layer app. Signed-off-by: Boon Khai Ng Reviewed-by: Tien Fong Chee
