... and read the whole manual there.

.eh_frame and COMMON are just some input section names presumably used by the compiler to locate certain code/data to where it belongs.

*(.rodata*) is an input section including any section starting with .rodata and whatever after it, eg. .rodata1234 or .rodata_foo; *(.rodata) is an input section (from any file, that's what the first asterisk indicates) which is called exactly .rodata
