I'll give it a shot:

Initilisation, normally the stack and processor setup that then calls main.

Finalisation.  Runs after your program finishes to tidy up.  Not
needed on embedded.

>>                 *(.eh_frame)
Exception handler frames.  Used to unwind the call stack when an
exception happens

No idea.  Might be an array of initialisation function pointers

'Java class registration'

>>                 *(.text)
Your application code

Sub sections of you application code.  With -ffunction-sections each
function gets split into its own '.text.function-name' section

Read only data such as constant strings, jump tables, etc.

>>                 *(.rodata*)
Per function rodata

I'd assume these are ARM/Thumb glue sections.
