MFC EFI support for the installer
r264978 (nwhitehorn):
Add EFI support to the installer. This requires that the kernel
provide a sysctl to determine what firmware is in use. This sysctl
does not exist yet, so the following blocks are in front of the
wheels:
- I've provisionally called this "hw.platform" after the equivalent
thing on PPC
- The logic to check the sysctl is short-circuited to always choose
BIOS. There's a comment in the top of the file about how to turn
this off.
If IA64 acquired a boot1.efifat-like thing (probably with very few
modifications), the same code could be adapted there.
r265016 (nwhitehorn):
Finish connecting up installer UEFI support. If the kernel was
booted using EFI, set up the disks for an EFI system. If booted from
BIOS/CSM, set up for BIOS.
r268256 (nwhitehorn):
After EFI support was added to the installer, it needed to allow
boot partitions of types other than "freebsd-boot" (in particular,
"efi"). This allows the removal of some nasty hacks for supporting
PowerPC systems, in particular aliasing freebsd-boot to apple-boot
on APM and an IBM-specific code on MBR.
This changes the installer to use the correct names, which also
breaks a degeneracy in the meaning of "freebsd-boot" that allows the
addition of support for some newer IBM systems that can boot from
GPT in addition to MBR. Since I have no idea how to detect which
those systems are, leave the default on IBM PPC systems as MBR for
now.
