From 94a78b79cb5f14c09a42522738d6694c6a1cdd20 Mon Sep 17 00:00:00 2001 From: Vladislav Zolotarov Date: Mon, 27 Apr 2009 03:27:43 -0700 Subject: bnx2x: Separated FW from the source. >From now on FW will be downloaded from the binary file using request_firmware. There will be different files for every supported chip. Currently 57710 (e1) and 57711 (e1h). File names have the following format: bnx2x--.fw. ihex versions of current FW files are submitted in the next patch. Each binary file has a header in the following format: struct bnx2x_fw_file_section { __be32 len; __be32 offset; } struct bnx2x_fw_file_hdr { struct bnx2x_fw_file_section init_ops; struct bnx2x_fw_file_section init_ops_offsets; struct bnx2x_fw_file_section init_data; struct bnx2x_fw_file_section tsem_int_table_data; struct bnx2x_fw_file_section tsem_pram_data; struct bnx2x_fw_file_section usem_int_table_data; struct bnx2x_fw_file_section usem_pram_data; struct bnx2x_fw_file_section csem_int_table_data; struct bnx2x_fw_file_section csem_pram_data; struct bnx2x_fw_file_section xsem_int_table_data; struct bnx2x_fw_file_section xsem_pram_data; struct bnx2x_fw_file_section fw_version; } Each bnx2x_fw_file_section contains the length and the offset of the appropriate section in the binary file. Values are stored in the big endian format. Data types of arrays: init_data __be32 init_ops_offsets __be16 XXsem_pram_data u8 XXsem_int_table_data u8 init_ops struct raw_op { u8 op; __be24 offset; __be32 data; } fw_version u8 >From now boundaries of a specific initialization stage are stored in init_ops_offsets array instead of being defined by separate macroes. The index in init_ops_offsets is calculated by BLOCK_OPS_IDX macro: #define BLOCK_OPS_IDX(block, stage, end) \ (2*(((block)*STAGE_IDX_MAX) + (stage)) + (end)) Security: In addition to sanity check of array boundaries bnx2x will check a FW version. Additional checks might be added in the future. Signed-off-by: Vladislav Zolotarov Signed-off-by: Eilon Greenstein Signed-off-by: David S.
