Sterling Hughes resolved MYNEWT-512.
------------------------------------
Resolution: Won't Fix
> Replace generated sysinit code with linker section
> --------------------------------------------------
>
> Key: MYNEWT-512
> URL: https://issues.apache.org/jira/browse/MYNEWT-512
> Project: Mynewt
> Issue Type: Improvement
> Reporter: Christopher Collins
> Assignee: Christopher Collins
> Fix For: v1_0_0_beta2
>
>
> *Old mechanism:*
> * pkg.yml file specifies "init_function" and "init_stage"
> * newt generates sysinit C files which call the packages' init functions in
> the specified order.
> *New mechanism:*
> * Each package defines an "init entry" struct containing:
> ** pointer to init function
> ** uint8_t stage
> * Init entry structs are placed in a special section.
> * At startup, the sysinit() function walks the list of entries in the special
> section and calls their corresponding init functions in the correct order.
> *Interface*
> {code}
> typedef void sysinit_init_fn(struct sysinit_init_ctxt *ctxt);
> struct sysinit_entry {
> sysinit_init_fn *init_fn;
> uint8_t stage;
> };
> struct sysinit_init_ctxt {
> const struct sysinit_entry *entry;
> uint8_t cur_stage;
> };
> #define SYSINIT_REGISTER_INIT(init_cb, init_stage) // ...
> {code}
> User defines a package initialization function and registers it.
> Registration creates a {{struct sysinit_entry}} instance in the special
> "sysinit" section.
> *Example:*
> {code}
> static void
> my_pkg_init(void)
> {
> /* ... */
> }
> SYSINIT_REGISTER(my_pkg_init, 2);
> {code}
