 * |        _stext      |
 * +--------------------+
 * | .data (ROM)        | initialized vars, copied to .data
 * +--------------------+
 * | .rodata            | Non-code data that can be put in far chunks
 * |        _srodata    |
 * +--------------------+ <- end of ROM
 * .                    .
 * .                    .
 * .                    .
 * +--------------------+ <- 0xFFFF0000
 * | .data (RAM)        | initialized data goes here
 * |        _sdata      |
 * +--------------------+
 * | .bss               |
 * |        _bss_start  | start of bss
 * |        _bss_end    | start of heap, for malloc()
