Author: kevans Date: Mon Mar 19 15:27:53 2018 New Revision: 331209 URL: https://svnweb.freebsd.org/changeset/base/331209 Log: Add note to UPDATING about UEFI changes requiring loader(8) update These problems have only been observed with boards using U-Boot (e.g. ARM) where virtual addresses are already set in the memory map by the firmware and the firmware is expecting a call to SetVirtualAddressMap to be made. I refrain from mentioning this in the note because this could also be the case on some not-yet-tested firmware on amd64 and it's not a bad recommendation for the general case.
