Subject: altos/telelco-v3: Create initial flash loader setup
X-Git-Tag: 1.9.18~2^2~71
X-Git-Url: https://git.gag.com/?p=fw%2Faltos;a=commitdiff_plain;h=50dea58c0f2ae87827a1a761ea7868e9798a5fd5

altos/telelco-v3: Create initial flash loader setup

Copied from easymega-v3 with USB pull-up moved to PA9. Note this
assumes the proto boards will have a resistor fitted there, which is
not in the artwork.
