No, this is nothing to do with arm64  itb.
You can over write this in your board if you use a different partition
table from Rockchip one.

We use 0x4000 because we have use this value for many years for U-Boot
image,
no matter it's uboot.img or u-boot.bin or u-boot.itb, I think it's better
to sync this
value for all Rockchip plaltform including Linux and Android OS in all SoCs.


Sorry, this I didn't understand we left 8M between SPL and U-Boot. What
exactly the use case I never observed any issue case like this.

Can you please elaborate, I understand I can override this but what to know
because generally falcon configuration itself start just from 2M
