当PROGRAMMABLE_RESET_ADDRESS=0,即core 启动地址固定时,需要需要平台实现机制(比如 mailbox)来判断 warm/cold boot。qemu board还不支持 warm boot, 故都走 cold boot流程。 在ARM FVP平台,PSYSR 包含cpu wakeup 的原因。若是GIC唤醒或者 PPONR(TODO) 则是 warm reset。当是 warm reset时,则从 trusted SRAM...
如果reset是可编程的,PROGRAMMABLE_RESET_ADDRESS=1, 则_warm_boot_mailbox=0,则下面这段代码不会被编译,无论cold boot还是warm boot都不会走_warm_boot_mailbox。 如果reset是不可编程的,PROGRAMMABLE_RESET_ADDRESS=0, 则_warm_boot_mailbox=1,则下面这段代码会被编译,但cold boot走do_cold_boot流程,warm ...
(2) _warm_boot_mailbox 判断当前启动方式是冷启动还是热启动(Reset、Reboot),并执行相应的处理, _warm_boot_mailbox 函数实现代码如下,根据 plat_get_my_entrypoint 获取热启动的地址,如果能正常获取地址则直接从热启动地址执行,如果不能则返回 0,表示此处启动为冷启动,机型执行冷启动流程。 .if\_warm_boot_m...

bl2_plat_preload_setup()中会初始化一堆硬件,包括读取RCW初始化Serdes等,初始化DDR4的代码:dram_init(),它在Plat\nxp\drivers\ddr\nxp-ddr下。比较遗憾的是DDR4 PHY的代码是个Binary,不含源码,这里对DDR4的初始化仅仅聚焦设置timing寄存器和功能寄存器,而没有内存的Training过程。
