* build bootloaders from codeBobby Bingham2015-09-154-3/+99
| | | | | | | | This adds the infrastructure for building from source the bootloaders which will go into the application initial program, in the boot sector. As a simple test case, it includes a simple bootloader which merely jumpts to the code address specified in the AIP, with the stack address specified there.
* make systemid structure match memory layoutBobby Bingham2015-09-152-16/+14
| | | | | | This will be useful when it comes time to share this structure definition with the bootloader code. Additionally, it makes the write_output function simpler, as we can output most of the fields with a single write() call.
* always output 8 region code blocks, simplifyBobby Bingham2015-09-151-15/+10
| | | | | | By always outputting a fixed number of region codes, we make it predictable at which address the initial program will be loaded. This may make it easier to develop alternate initial program implementations.
* fix incorrect accounting of region codes in output sizeBobby Bingham2015-09-151-5/+8

* add a default initial programBobby Bingham2015-09-151-6/+27
| | | | | This initial program will simply jump to the address to which the first read file is loaded. This is what 90% of callers will probably want.
