Split the flash loader prototype into pieces so that each product can
build a custom flash loader with very little code.

altos: Add erase command to stm-flash app. Validate addresses.2013-05-08T03:16:52+00:00Keith Packardkeithp@keithp.com2013-03-23T09:23:03+00:00urn:sha1:5db4d5e5b1272b161102e889e65b9c7bc7928352
This also leaves the code writing fixed values and printing read data
in ascii instead of binary. Useful for debugging, will want changing
for the product.

This shrinks the base OS load down a bit as well so that stm-flash
fits comfortably in the first 8kB of memory.

Add STM self-flashing loader2013-05-08T03:12:40+00:00Keith Packardkeithp@keithp.com2013-02-24T08:18:14+00:00urn:sha1:a6887032b4d217bca5236ea15389218f10d69545
This allows the real application to get loaded at 0x2000 and jumps to
that at startup time if the boot pin is set appropriately
