esp8266: Add Python modules for initial configuration. Main entry point is _boot.py which checks whether FAT FS in flash mountable, and if so, mounts it. Otherwise, it checks if flash is empty, and if so, performs initial module setup: makes FAT FS, configures default AP name, etc. As a last option, if flash is not empty, and could not be mounted, it means filesystem corruption, and warning message with instructions is printed in an infinite loop. 2016-04-12 05:37:04 +08:00			`import uos`

esp8266/scripts/_boot: Mount block device on "" instead of "/". "" is the correct name of the root directory when mounting a device there (as opposed to "/"). One can now do os.listdir('/') and open('/abc'), as well as os.listdir() and open('abc'). 2016-04-15 05:56:21 +08:00			`vfs = uos.VfsFat(bdev, "")`
