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.

main()
{
	uart_select_init();
	printf("Hello-world demo app running\n");
	print_boot_rom_info();
	for (;;) {
		putchar('=');
		if (command_entry())
			command_dispatch();
	}
}
