SYNOPSIS
       int allocate_resource(struct resource * root, struct resource * new, resource_size_t size,
                             resource_size_t min, resource_size_t max, resource_size_t align,
                             resource_size_t (*alignf) (void *, const struct resource *, resource_size_t, resource_size_t),
                             void * alignf_data);

ARGUMENTS
       root
           root resource descriptor

       new
           resource descriptor desired by caller

       size
           requested resource region size

       min
           minimum boundary to allocate

       max
           maximum boundary to allocate

       align
           alignment requested, in bytes

       alignf
           alignment function, optional, called if not NULL

       alignf_data
           arbitrary data to pass to the alignf function
