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 _sprintf_putchar();

int
sprintf(char *strdest, char *fmt, ...)
{
	va_list ap;
	char *strptr;
	int len;

	strptr = strdest;
	va_start(ap, fmt);
	len = _doprnt(fmt, ap, &_sprintf_putchar, &strptr);
	va_end(ap);
	*strptr = '\0';
	return(len);
}
