The OpenSBI licence was updated to include contributors in the
copyright notice.
The payload logic has been updated to fix some bugs and handle the new
optional dependency on the Linux kernel for device trees

-Subject: [PATCH] lib: Create a sbi_ipi_data structure
-
-Create a sbi_ipi_data structure that holds unpacked IPI information. At
-the same time remove ipi_type from the sbi_scratch struct and use a
-fixed offset to access it.
-
-This structure fits in behind the sbi_scratch structure.
-
-This fixes https://github.com/riscv/opensbi/issues/81
-
-Upstream-Status: Backport
