* stand/efi: allow not exiting boot servicesRoger Pau Monné2021-02-161-2/+3
| | | | | | | | | | | | | | | | | | Xen requires that UEFI BootServices are enabled in order to boot, so introduce a new parameter to bi_load in order to select whether BS should be exited. No functional change introduced in this patch, as all current users of bi_load request BS to be exited. Further changes will make use of this functionality. Note the memory map is still appended to the kernel metadata, even when it could be modified by further calls to the Boot Services, as it will be used to detect if the kernel has been booted from UEFI.

* Stop setting PG_U in bootstrap mappings.Mark Johnston2020-04-241-3/+3
| | | | | | | | | | | | | | These mappings are never visible to userspace as they get replaced when the amd64 pmap is bootstrapped, but there is no need to set PG_U in the first place.

* loader: use teken teminal emulator for x86 and uefiToomas Soome2019-09-051-1/+1
| | | | | | | | | | | Replace mini cons25 emulator with teken, this does enable us proper console terminal for loader and will make it possible to implement different back end callbacks to draw to screen. At this time we still only "draw" in text mode. Notes: svn path=/head/; revision=351900
