Issue Description
I read Bootburn Usage | NVIDIA Docs but the answer was not clear from this documentation.

I would like to change the partition sizes and other variables in my target configuration. I see many, many ‘.cfg’ files in the Drive SDK Docker container. I used strace to instrument bootburn file reads, and discovered that bootburn was reading these files named '.cfg’:

/drive/drive-foundation/out/p3710-10-s05/boot_chain_c_storage.cfg
/drive/drive-foundation/out/p3710-10-s05/boot_chain_storage.cfg
/drive/drive-foundation/out/p3710-10-s05/custom_storage_emmc.cfg
/drive/drive-foundation/out/p3710-10-s05/global_storage.cfg
/drive/drive-foundation/out/p3710-10-s05/linux_chain_c_storage.cfg
/drive/drive-foundation/out/p3710-10-s05/linux_storage.cfg
/drive/drive-foundation/out/p3710-10-s05/qnx_update_vm_chain_c_storage.cfg
/drive/drive-foundation/out/p3710-10-s05/qnx_update_vm_storage.cfg
/drive/drive-foundation/tools/flashtools/flashing_kernel/flashing_configs/t23x/quickboot_flashing.cfg

Which of these files are actually used for the configration of the target boot storage device?
Why is bootburn reading so many different config files?

Error String
N/A

Logs
The strace logs are too copious to paste here.

Dear @dwuertele,
May I know what you want to change in storage device? Is it eMMC or UFS?

I want to know the entire mapping. Which file is used for what?

Does NVIDIA DRIVE AV Storage Configuration | NVIDIA Docs helps?

Dear @dwuertele ,
Does the above suggestion helps? can we close the topic?
