The secure_partition_boot_info_t structure is used to communicate boot parameters with the StandaloneMM code executing at S-EL0 through a shared buffer. Certain data types used for members of this structure are opaque with their size depending on the toolchain being used. Declare the members of the structure with explicit width based data types, which would maintain compatibility across toolchains. Signed-off-by: Sughosh Ganu <sughosh.ganu@arm.com>
