..data is initialized data.  Consumes RAM and ROM (for the initializers).
..text is the executable code, plus ROM constants.  Consumes ROM.
..bss  is uninitialized data.  Consumes RAM, will be cleared to 0 by the
      the startup code.
..noinit is unititialized data.  Consumes RAM, will not be touched by
      the startup code (IOW: survives a reset).
..eeprom is initialized data.  Consumes EEPROM, you gotta transfer the
      data to EEPROM yourself using the programmer.
..stab and .stabstr contain debugging information only.  Will not be
      transfered to the device, only meaningful to debuggers.

So your ROM consumption is the sum of .text + .data.  Your RAM
consumption is the sum of .data + .bss + .noinit, plus any dynamic
memory you might use, plus the stack.
