How to get information for RAM usage of components for WP7605 software/firmware

I would like to check which addresses in WP7605 RAM are used by four software/firmware components: Modem Firmware, Linux Distro, Base Legato System, and Overlay Legato System.
I found that a file shows the addresses used by Linux Distro. The file is in ~/yocto/build_bin/tmp/work/swi_mdm9x28_wp-poky-linux-gnueabi/linux-quic/3.18.131-r1/build directory.
However I cannot find information for the address used by the other three components (Modem Firmware, Base Legato System, and Overlay Legato System).

Would you tell me how to get the information?

I will use the information for estimating how many additional bytes in RAM I can use for the Linux Distro to add functions to the Linux Distro.

have you tried the pmap command?
For example, you can search the pid of each process by “ps aux”, and then you can use “pmap pid” to find the memory mapping.
