2025-05-15wifi: iwlwifi: rename ctx-info-gen3 to ctx-info-v2Miri Korenblit
Context info was introduced in 22000, and was significantly changed in ax210. The new version of context info was called 'gen3', probably because in 22000, the gen2 transport was added. But this name is just wrong: - if 'gen' enumerates transports, there was not a gen3 transport, just a few modifications to gen1/2 transports needed for ax210. - if 'gen' enumerates devices, then we can just use the device names. Also, context info will soon become a lib, agnostic of the transport generations. Simply replace 'gen3' with 'v2'.

2025-05-07wifi: iwlwifi: move STEP config into trans->confJohannes Berg
This really belongs there, it's needed early, so move it. Remove the related but dead iwl_trans_pcie_ctx_info_gen3_set_step() while at it. In iwlmld move the calls since they do part of the trans configuration.

2025-05-07wifi: iwlwifi: pass full FW info to transportJohannes Berg
The code currently passes only the specific image that should be loaded, but then has to pass the IML (image loader) out of band, which is confusing. Pass the full FW data together with desired image type, and use the IML from that. This also cleans up the code in the various sub-drivers a bit as they no longer have to look up and check for the image.

Moreover, its more compatible for handling larger pnvm tables in the future (in which payloads won't be concatenated). The main changes are: 1.

Context information structure was added to 22000 devices for firmware self init. In the next generation of devices the context information changes significantly, and the original context information is divided roughly to three data structures: context information gen3, prph information and prph scratch. In addition, the init flow changes so the firmware is loaded by the IML, and so we must allocate the IML on the DRAM and give the ROM the IML's address before kicking the firmware's self init.
