Patch queue for efi - 2017-07-29
A lot of EFI greatness this time around. Thanks a lot to the two amazing new contributors Heinrich Schuchardt and Rob Clark we now gain - stable objects across multiple bootefi invocations - fixes for shim - fixes for ipxe - protocol installation - device path conversion to/from text - working "lsefi" support in grub - working notifiers - various bug fixes -----BEGIN PGP SIGNATURE----- Version: GnuPG v2 iQIcBAABAgAGBQJZe7lWAAoJECszeR4D/txg58IQALyjPiP2OWgYE/PnjliiTMjo m0I0u89C2g59Nqd43gLVL1qj85hnQt7X9xzGt3D+r1NSZUrGBlhF7t2guvxwzHhU G2nN34HT9Ef1+30iwK6tdy+y6kdr92Z7CPn+SC9rgXjLNtjUoCHzuAVyuRZq+Vyp JVod9UCIb6rj6+j48V2fKx0KZQd+rJXPecEk02iRc9pJrye0RZH/AB1KOm41G6V+ A0PW6v1//1i9rlmSFWW2MV2R4P2op6D9BPxyJpKErUIIQnsVXA7AZ8aeQmBIYBa9 EY8hLu20kFIItDv4aMJVD8ZN5addqqtEnnxFEBrMBaB3UOZZTYDD3p13/NVLyK0U sQXIXhxegA7Ywyfrsm1uUwUmntvyBv8yfKIYrMCSIAkzY+6Dk2Uu/LamyI81TddM nFQsEWsNBdppkgRWFvEI9RsrG3G0sP6F82/y6/DiW02+25tt8CYzOsmaxBNUqesK jT0rr3n86zx2ob0erBaQk4dGhmjGhNN7TYjctOkqD+3hTtgb2QrAC/v0H/mTN3AU ab7LB6O3b4+lQLvKl8BVmH7AhtXSiVV8j2282rjd0YJslzxCzUwCGGrzO3HnqSQY YCQE0NG6/qEe2lR94emv+V+qxlRal4Q+GUbGeoA35dHSYQ8o7LRKbATWmVo64m/0 BC/9odtC7sM7yRU/y6V6 =djrH -----END PGP SIGNATURE----- Merge tag 'signed-efi-next' of git://github.com/agraf/u-boot Patch queue for efi - 2017-07-29 A lot of EFI greatness this time around.
