Yep. W = read/write and X = execute.

The only reason for doing this is so if the linker doesnt have somewhere to
put an object, it can have a good guess from what the object and memory
regions are marked as.

Yes. *(*) would be all files, all segments. *.o(.code) would be all code
segments of *.o files.

Technically you dont need it... :)

The AT just tells the linker where to put the data in the generated ROM. The
other address is the address of the symbol.

This is all just so you can have code in ROM but referenced in RAM. It's
then up to you to do relocation...
