Provide six initcall levels for drivers/modules initialize HW controllers or runtime arguments during cold boot. The initcall level cold boot execution order: -MTK_EARLY_PLAT_INIT Call before MMU enabled. -MTK_ARCH_INIT MMU Enabled, arch related init(GiC init, interrupt type registration). -MTK_PLAT_SETUP_0_INIT MTK driver init level 0. -MTK_PLAT_SETUP_1_INIT MTK driver init level 1. -MTK_PLAT_RUNTIME_INIT MTK driver init. After this initcall, TF-A handovers to MTK 2nd bootloader. -MTK_PLAT_BL33_DEFER_INIT MTK 2nd bootloader traps to TF-A before handover to rich OS. This initcall executed in the trap handler(boot_to_kernel). Signed-off-by: Leon Chen <leon.chen@mediatek.com> Change-Id: Icd7fe95372441db73c975ccb6ce77a6c529df1cc
