Just as we recently added support for other stored firmware flash versions, support display of the stored UNDI Option ROM version via devlink info. To do this, we need to introduce a new ice_get_inactive_orom_ver function. This is a little trickier than with other flash versions. The Option ROM version data was being read from a special "Boot Configuration" block of the NVM Preserved Field Area. This block only contains the *active* Option ROM version data. It is populated when the device firmware finishes updating the Option ROM. This method is ineffective at reading the stored Option ROM version data. Instead of reading from this section of the flash, replace this version extraction with one which locates the Combo Version information from within the Option ROM binary. This data is stored within the Option ROM at a 512 byte offset, in a simple structured format. The structure uses a simple modulo 256 checksum for integrity verification. Scan through the Option ROM to locate the CIVD data section, and extract the Combo Version. Refactor ice_get_orom_ver_info so that it takes the bank select enumeration parameter. Use this to implement ice_get_inactive_orom_ver. Although all ice devices have a Boot Configuration block in the NVM PFA, not all devices have a valid Option ROM. In this case, the old ice_get_orom_ver_info would "succeed" but report a version of all zeros. The new implementation would fail to locate the $CIV section in the Option ROM and report an error. Thus, we must ensure that ice_init_nvm does not fail if ice_get_orom_ver_info fails. Use the new ice_get_inactive_orom_ver to allow reporting the Option ROM versions for a pending update via devlink info.
