[PATCH 0/3] discover: Check if the kernel image has Ultravisor support

[Maxiwell S. Garcia]

Hi,

The PPC kernel image has an ELF Note 'namespace' called 'PowerPC'
to store capabilities that indicates if the powerpc kernel binary
knows how to run in an ultravisor-enabled system.

This patchset enables petitboot to read the ELF structures of
kernel binary using the libelf as low-level support and get the
kernel image ELF Note capabilities. If that image is not compatible
with the system, the boot process is aborted.

  configure: Add libelf as a requirement
  discovery: Add helper functions to read ELF notes
  discover: Check if the kernel image has Ultravisor support
