The mlxfw module is in charge of common logic needed to flash Mellanox devices firmware, which consists of: - Parse the Mellanox Firmware Archive version 2 (MFA2) format, which is the format used to store the Mellanox firmware. The MFA2 format file can hold firmware for many different silicon variants, differentiated by a unique ID called PSID. In addition, the MFA2 file data section is compressed using xz compression to save both file-system space and memory at extraction time. - Implement the firmware flash state machine logic, which is a common logic for Mellanox products needed to flash the firmware to the device. As the module is shared between different Mellanox products, it defines a set of callbacks to be implemented by the specific driver for hardware interaction.
