loadtools: round out support for Intel flash families The three Intel flash families encountered so far in Calypso GSM devices are C3, W30 and W18, sizes from 2 to 8 MiB. Let's support all Intel flash chips from these 3 families across this range of sizes.

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