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-<chip version>-<FW version>.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.
