-	io_nmmc.c
-
-	Hardware Routines for reading an SD or MMC card using
-	a Neoflash MK2 or MK3.
-
-	Written by www.neoflash.com
-
-	Submit bug reports for this device to the NeoFlash forums
-
-	See license.txt for license details.
-
-	2006-02-09 - www.neoflash.com:
-	 * First stable release
-
-	2006-02-13 - Chishm
-	 * Added ReadMK2Config function
-	 * Added read config test to init function so no unnecessary card commands are sent
-	 * Changed data read and write functions to use multiple block commands
