From: Tom Rix <trix@xxxxxxxxxx> Depends on https://lore.kernel.org/linux-fpga/20210623182410.3787784-1-trix@xxxxxxxxxx/ A refactor of the fpga-manager to make space for the functionality of the secure update in this thread. https://lore.kernel.org/linux-fpga/20210517023200.52707-1-mdf@xxxxxxxxxx/T/#mf3a1951d429a973c863eee079ed990c55056827c Splits the reconfig write ops into its own ops structure and then has an instance for the existing loading (reconfig) and the secure update (reimage) fpga_mgr_load uses a new bit, FPGA_MGR_REIMAGE, in fpga_info_info to use either the reconfig or the reimage ops. valid write op checking has moved to make the reimage path option. Since fpga_image_info_alloc zalloc's the fpga_info_struct, the reimage path will not be taken. Stub in remimage support for dfl Changes since v1: - update op names changed from partial_update to reconfig full_update to reimage - dropped the cancel() and get_error() ops. - add FPGA_MGR_REIMAGE bit - refactor fpga_mgr_load to use either update ops Changes since v2: - Fix a missed write op change - Stub in dfl reimage Changes since v3 - refactor for wrapper ops patchset - drop 0004 fpga: defer checking.., wrapper ops took care of that - drop 0006 fpga: dfl stub in..., simplify the patchset - add a wrapper for write_sg - rearrange the passing of update ops to be last. - simplify some wrapper checks, this should go in the wrapper ps. Tom Rix (5): fpga: generalize updating the card fpga: add FPGA_MGR_REIMAGE flag fpga: pass fpga_manager_update_ops to the fpga_manager_write functions fpga: use reimage ops in fpga_mgr_load() fpga: fpga-mgr: simplify mops check in wrappers drivers/fpga/altera-cvp.c | 8 +-- drivers/fpga/altera-pr-ip-core.c | 8 +-- drivers/fpga/altera-ps-spi.c | 8 +-- drivers/fpga/dfl-fme-mgr.c | 8 +-- drivers/fpga/fpga-mgr.c | 103 +++++++++++++++++++------------ drivers/fpga/ice40-spi.c | 8 +-- drivers/fpga/machxo2-spi.c | 8 +-- drivers/fpga/socfpga-a10.c | 10 +-- drivers/fpga/socfpga.c | 8 +-- drivers/fpga/stratix10-soc.c | 6 +- drivers/fpga/ts73xx-fpga.c | 6 +- drivers/fpga/xilinx-spi.c | 8 +-- drivers/fpga/zynq-fpga.c | 10 +-- drivers/fpga/zynqmp-fpga.c | 6 +- include/linux/fpga/fpga-mgr.h | 35 +++++++---- 15 files changed, 140 insertions(+), 100 deletions(-) -- 2.26.3
