DRAM Space Allocation
The diagram below illustrates the DRAM allocation during U-Boot execution.
...
Each segment serves a specific purpose:
null_pointer_prot: Reserved for null pointer protection, this segment is never mapped to physical memory, ensuring safety from accidental memory access.
warm-boot: Holds the code responsible for resuming the system from deep sleep mode.
BL31: Contains the BL31 firmware code as part of the Trusted Firmware-A (TF-A).
OP-TEE OS: Stores the OP-TEE OS and its applications. This segment is designated as a secure zone in the x-boot process.
uboot: Initially used to load the U-Boot image. The image is later relocated to the end of DRAM.
temporary: An unused segment, currently reserved for potential future purposes.
kernel: Allocated for the Linux kernel image, where the image is loaded, decompressed, and executed.
relocated_uboot: U-Boot is relocated to this segment at runtime, which is typically located at the very end of system DRAM.
