Hello, I read the startup script of uboot.ush, and I think the environment variable ramdisk_addr_r refers to the memory address that can be used in uboot. But I want to know why this value is 0x0a400000. Is it because this is the starting address of dram1 that it was changed to this value?

It is located there so that it comes after the region of memory used by OPTEE.

How do you know that the memory area used by optee overlaps with the ramdisk_addr_r address?
