mirror addresses - Githubissues

Sorry for question, but i don't found, how to specify that addresses 0x80001234 and 0xA0001234 point to the same location?

Not certain on best approach, but you can file->'add to program' and select same ROM. In that popup you'll want to click 'Options' where you can specify alternate load address, offset into file, data Len, and block name

Ok, thanks. IDA converts this automatically (when i name dword 0xA000abcd as pointer, it become indicate to 0x8000abcd). For me, this task looks like good start point to learn how to write plugins for Ghidra ;-)

I asked a Dev in my pull request. Seems possible both in code and when loading from his answer

Sorry hadn't had much time to play with this. Do not know how to automate this, but it seems really good from a quick glance with this setup:

load rom at 0x80000000, don't auto-analyze yet
open memory map settings, add new, add a name, offset 0xA0000000, length 0x180000, click execute check-box, choose byte-mapped in drop down, new address option should already be 0x80000000.
open memory map settings, add new, add a name, offset 0xC0000000, length 0x180000, click execute check-box, choose byte-mapped in drop down, new address option should already be 0x80000000.
save memory map
auto-analyze e/ well maybe i don't know what i'm looking at, seeing some issues. but is this closer to what you were looking for
