- * Name: nxflat_addrenv_alloc
- *
- * Description:
- * Allocate memory for the ELF image (elfalloc). If CONFIG_ADDRENV=n,
- * elfalloc will be allocated using kzalloc(). If CONFIG_ADDRENV-y, then
- * elfalloc will be allocated using up_addrenv_create(). In either case,
- * there will be a unique instance of elfalloc (and stack) for each
- * instance of a process.
- *
- * Input Parameters:
- * loadinfo - Load state information
- * envsize - The size (in bytes) of the address environment needed for the
- * ELF image.
- *
- * Returned Value:
- * Zero (OK) on success; a negated errno value on failure.

- *
- * Description:
- * Release the address environment previously created by
- * nxflat_addrenv_create(). This function is called only under certain
- * error conditions after the the module has been loaded but not yet
- * started. After the module has been started, the address environment
- * will automatically be freed when the module exits.
- *
- * Input Parameters:
- * loadinfo - Load state information

- * Returned Value:
- * None.
