Pull request for UEFI sub-system for efi-2020-10-rc5 (2)
The following bugs are fixed: * incorrect online help for setenv and env * description of function efi_mem_carve_out() * replace printf() by log_err() in stm32mp1_rng driver A unit test is provided to check that the boot hart id is provided in the RISC-V device-tree. -----BEGIN PGP SIGNATURE----- iQIzBAABCAAdFiEEbcT5xx8ppvoGt20zxIHbvCwFGsQFAl9lGSsACgkQxIHbvCwF GsRXKQ//b4cX6tfXy5PFbNf59bTCy4TdCR2/7c0vjMwNbSpemjVDqms8iOrtwaFB /dPYC9sJoXXnoY8yq/TZpbamT9rY8f42ZlB+OlWdDXH5v5EJJjw/blaZRMS8z46/ NYjHfKZC5LafsfWOzcA403g4Bk2rlJEvAcruz15aLa3hACZ4T7s4C1zBZW87t2KD 57AGWagcyfGbd1oBzJWlSJSpjff8g4yC9XAn4yNtyCKTn5vy0FSXWp6M3wGfK+rG KISHmdUsm92cU3z41NIXkaWNfhpkI1krpFyblJEUnjpErvBxxCUecCmd65NNYk4P Xus1D4tS6vQGZc5Xmq+RskyPl6o2qtpowno/UpcpQUkdCucfldTsSYWufR7txebf H3KAQC/TMJ7WKlSMz3xqVIhRvtWxXazIh4os07EOU2F99OdNcOFvCEUJc4kBmgZk TwDv1Z/Iz2stMdRNCFCJpZKVVuwj7qjZ+R83FzUBC8ueWMqERLAhdMwes9CK3N3b vz4fBBNfml3UludIaCbNcQk2d8kTDZLWokRqRjE3j3McMQnSU1ffipRWUy+4qJ9q 6Py82OpUT3g1x5S4lD/Z5jdxS2kYqpZAOHfQpcWs1RMmF8NtW0MOoWXZvYOkxOX7 DjBysIkls4jB/Wn9z+oiqHkVV4yCh0ZrGhNFSzDgWSF4jbAqnlc= =vhkz -----END PGP SIGNATURE----- Merge tag 'efi-2020-10-rc5-2' of https://gitlab.denx.de/u-boot/custodians/u-boot-efi Pull request for UEFI sub-system for efi-2020-10-rc5 (2) The following bugs are fixed: * incorrect online help for setenv and env * description of function efi_mem_carve_out() * replace printf() by log_err() in stm32mp1_rng driver A unit test is provided to check that the boot hart id is provided in the RISC-V device-tree.
