 * Unlike other files, this one should be compiled with a -m option to
 * specify a pre-determined instruction set. The is to ensure consistency

 * occurs.
 *
 * Entry points must be placed at the location the previous stage jumps
 * to (the lowest address in the stage image). This is done by giving
 * stage_entry() its own section in .text and placing it first in the
 * linker script.
