They are just for test and please ignore them because dts/upstream should be synced with devicetree-rebasing. [1] https://lore.kernel.org/all/[email protected]/ Changes since RFC: - Rebase on the latest mainline. - Improve the commit messages. - Drop patch 7. patch 3, 4: - Return 0 instead of 0xFF if read_eeprom() fails. patch 5: - Keep default FORMAT_VERSION 0x2. - Change wifi_bt field to onboard_module field and use bit 0 to mark WIFI/BT. - Drop all "no_eth0", "no_eth1" configuration.
