1	m1nor - Flash a file to M1 NOR partition selected by the file name
2	==================================================================
3
4	During software development, one often need to update only the
5	content of a single partition. reflash_m1.sh is a bit unwieldy
6	for this kind of task.
7
8	I've written a small script called m1nor that selects the target
9	partition based on the file name. E.g., m1nor flickernoise.fbi
10	would update the regular Flickernoise partition.
11
12	The matching algorithm checks the beginning of the file name,
13	so names like flickernoise-test.fbi would also work. Furthermore,
14	it checks the file extension, so if you try to flash flickernoise
15	(ELF, for debugging) or flickernoise.bin (an intermediate form
16	unsuitable for booting from NOR), it will politely refuse to do
17	so.
18
19	You need to have fjmem.bit somwehere. It searches for it under
20	$HOME/.qi/milkymist/, where reflash_m1.sh caches it. You can also
21	specify the location directly by setting the environment variable
22	FJMEM_BIT.
