ovmf_git.bb: enable Secure Boot
When enabled via PACCKAGECONFIG = "secureboot" (off by default because of the extra work and license change), the recipe compiles OVMF twice, once without Secure Boot, once with. This is the same approach as in https://src.fedoraproject.org/cgit/rpms/edk2.git/tree/edk2.spec The results are "ovmf.qcow2" and "ovmf.secboot.qcow2" in the image deploy directory, so runqemu <machine> <image> ovmf.secboot will boot with Secure Boot enabled. ovmf.secboot.code.qcow2 is provided for those who want separate code and variable flash drives. The normal ovmf.vars.qcow2 can be used with it. In contrast to Fedora, no attempt is made to strip potentially patent encumbered algorithms out of the OpenSSL archive. OVMF does not use the ones considered problematic for Fedora, so this shouldn't be a problem. Fixes: luv-yocto/#38 Signed-off-by: Patrick Ohly <patrick.ohly@intel.com>
