From: Tom Rix <trix@redhat.com> 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@kernel.org/T/#mf3a1951d429a973c863eee079ed990c55056827c (local) 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. 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 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: defer checking for update ops until they are used fpga: use reimage ops in fpga_mgr_load() 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 | 10 ++--- drivers/fpga/fpga-mgr.c | 72 ++++++++++++++++++++------------ 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 | 8 ++-- drivers/fpga/ts73xx-fpga.c | 8 ++-- drivers/fpga/xilinx-spi.c | 8 ++-- drivers/fpga/zynq-fpga.c | 10 ++--- drivers/fpga/zynqmp-fpga.c | 8 ++-- include/linux/fpga/fpga-mgr.h | 35 +++++++++++----- 15 files changed, 125 insertions(+), 92 deletions(-) -- 2.26.3 _______________________________________________ linux-arm-kernel mailing list linux-arm-kernel@lists.infradead.org http://lists.infradead.org/mailman/listinfo/linux-arm-kernel
