fpga: m10bmc-sec: Fix possible memory leak of flash_buf

2022-09-19T04:58:19Z

There is an error check following the allocation of flash_buf that returns without freeing flash_buf. It makes more sense to do the error check before the allocation and the reordering eliminates the memory leak.

fpga: m10bmc-sec: d5005 bmc secure update driver

2022-09-11T07:36:35Z

Add a driver name for the D5005 BMC secure update driver. Different driver names are used for the N3000 and D5005 devices because future changes will add conditional code based on the device type (N3000 vs D5005). This change enables D5005 secure updates of BCM images, BMC firmware, static-region images, etc. Signed-off-by: Russ Weight Acked-by: Xu Yilun Link: https://lore.kernel.org/r/20220902165706.518074-3-russell.h.weight@intel.com Signed-off-by: Xu Yilun

fpga: fpga-mgr: support bitstream offset in image buffer

2022-06-24T04:11:18Z

At the moment FPGA manager core loads to the device entire image provided to fpga_mgr_load(). But it is not always whole FPGA image buffer meant to be written to the device. In particular, .dat formatted image for Microchip MPF contains meta info in the header that is not meant to be written to the device. This is issue for those low level drivers that loads data to the device with write() fpga_manager_ops callback, since write() can be called in iterator over scatter-gather table, not only linear image buffer. On the other hand, write_sg() callback is provided with whole image in scatter-gather form and can decide itself which part should be sent to the device. Add header_size and data_size to the fpga_image_info struct, add skip_header to the fpga_manager_ops struct and adjust fpga_mgr_write() callers with respect to them. * info->header_size indicates part at the beginning of image buffer that contains some meta info. It is optional and can be 0, initialized with mops->initial_header_size. * mops->skip_header tells fpga-mgr core whether write should start from the beginning of image buffer or at the offset of header_size. * info->data_size is the size of bitstream data that is meant to be written to the device. It is also optional and can be 0, which means bitstream data is up to the end of image buffer. Also add parse_header() callback to fpga_manager_ops, which purpose is to set info->header_size and info->data_size. At least initial_header_size bytes of image buffer will be passed into parse_header() first time. If it is not enough, parse_header() should set desired size into info->header_size and return -EAGAIN, then it will be called again with greater part of image buffer on the input.
