H A D | init.c | 67eebf72 Mon May 13 07:32:43 CDT 2019 Marcin Nowakowski <marcin.nowakowski@fungible.com> generic: fix appended dtb support
Appended DTB support is mostly intended to be used on legacy systems, but it is a valid feature that can be enabled for generic platform, which currently doesn't support it - if selected, the appended DTB will be ignored by the platform startup code.
During kernel startup, the appended DTB's location is stored in fw_passed_dtb if the init code finds what appears to be a valid DTB. Otherwise (if a0 == -2), a1 is stored in fw_passed_dtb, so either way it will always point to either a user-passed DTB or built-in DTB.
