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.

#include <stdarg.h>

extern void putchar();

int
vprintf(fmt, ap)
	char *fmt;
	va_list ap;
{
	return(_doprnt(fmt, ap, &putchar));
}
