loadtools: Mot C155 turns out to have the same flash partition quirks as the flash chip on TI's D-Sample c155.config changed to use the fixed 28f640w30b config instead of CFI, and a bit of C code in fc-loadtool had to be changed too so that flash erase-program-boot still works.

char *
index(p, ch)
	register char *p, ch;
{
	for (;; ++p) {
		if (*p == ch)
			return(p);
		if (!*p)
			return((char *)0);
	}
	/* NOTREACHED */
}
