The Arria10 SPL is a complete mess of calls to functions which are called in the wrong context and it is surprise it works at all. This patch tries to clean that mess up by shuffling the function calls around and moving the calls into the correct context. Due to the delicate nature of the reordering, this is done in one huge patch. The following changes happen in this patch: - Security policy init and NIC301 happens first in board_init_f() - The clock init happens very early in board_init_f() in SPL only - arch_early_init_r() only registers the FPGA, just like on Gen5 - arch_early_init_r() is never called from any _f() function - Dedicated FPGA pins are inited in board_init_f() as on Gen5 Signed-off-by: Marek Vasut <marex@denx.de> Cc: Chin Liang See <chin.liang.see@intel.com> Cc: Dinh Nguyen <dinguyen@kernel.org> Cc: Ley Foon Tan <ley.foon.tan@intel.com>
