From: Thierry Reding <[email protected]> This fixes some build errors and warnings caused by inline assembly and pointer to integer cast size mismatches. The inline assembly build error in config_cache() is easy to fix because the code isn't meaningful on 64 bit ARM. For the assembly-level reset_cpu() implementation, provide a version that uses ARMv8 register names, but is otherwise identical.
The remaining warnings about pointer to integer cast size mismatches can be fixed by simply using explicit casts where appropriate, or using long unsigned integers rather than 32-bit sized types where an actual address is stored.
