[PATCH V2 1/2] imx: imx8mp_evk: fix boot issue

The u-boot-spl.bin pad with ddr firmware conflicts with the CONFIG_MALLOC_F_ADDR area, the ddr firmware will be overwritten by malloc in SPL stage and cause ddr initialization not able to finish. So update the related addresses to fix the issue.

Simplify board SPL code - BSS area will be cleared by crt0_64.S - No need to get ccm device in spl_board_init - Use spl_early_init, not spl_init - timer_init has been invoked in arch_cpu_init

These are several changes in the same patch. It would be better to split them.

We need this for the SPL watchdog driver, no?

You should check the returned value from spl_early_init().

No. clk is enabled in clock_imx8mm.c.
I tried selecting CONFIG_SPL_CLK_IMX8MP=y and then the board does not boot anymore, so it looks like we need a better solution.
Let's not enable this for SPL. We have limited ram, I plan to disable CCF in SPL.

U-Boot proper should use ATF to reset. I think it might be using wdog here.
Also, could you please make sure it can boot a NXP 5.4.3_2.0.0 kernel?
ok, will give a try.
Thanks, Peng.
