This only works via EFI shell because we need to pass boot params to
kernel.
An aditional EFI shell is provided with an startup script for
automatic booting.

You need to use
https://edk2.svn.sourceforge.net/svnroot/edk2/trunk/edk2/EdkShellBinPkg/FullShell/X64/Shell_Full.efi
as ShellBinPkg shell will work only in 2.2+ systems (most of the Arch
Lenovo UEFI users reported ShellBinPkg Shell.efi as not working. More
info at http://sourceforge.net/mailarchive/message.php?msg_id=28690732
.
Technically needs 2.3+.
I thinking to EdkShellBinPkg that is based on (pre)UEFI 2.0. Looks
like there are lots of of poor/old UEFI implementation even in newer
hardware so can be more safe to provide and old shell.
This is temporary until EFI_STUB understand "linux.conf" (maybe in
Linux-3.5, since 3.4 merge window is closed without it).
Anyway I think that providing a shell with script, is much more
flexible, since you can skip it then execute vmlinuz.efi with custom
boot params if needed.

Are you sure this will work without cd'ing into fso: first? Did you
test this in real hardware like ENV (like DUET
http://www.rodsbooks.com/bios2uefi/index.html)
Yes, indeed I use DUET even for qemu since with OVMF has video issues
(there is no video output from Linux).
Think that when boot/bootx64.efi is executed you are currently on fs0:
;) Maybe a poor UEFI implementation fails, who know?, anyway you are
dropped to the shell, and if shell fails, this is very very bad, we
can not support broken hardware addding exceptions.
When using older shell, is needed to change first to fs0:. I Added it to
startup.nsh
Thanks for your work on UEFI things, and thanks for the feedback.
