Consider dedicating some flash for configs #10

Open jonlamb-gh opened 1 year ago

So things like IP and MAC address can be changed without re-flashing firmware. Add some config update commands to the CLI for setting them. Other potentially useful things to have:

max log level (i.e. trace vs info)
last panic message
last reset reason from panic
env-config constants are used to build up the default config struct values

Boot and application configs in sector 3 (0x0800_C000) as of adb15738a05430141ecf259f89fdc9bfbfa76ee9 Not currently exposing any configs yet, just bootloader flags

The bootloader is pretty small, it can fit in sectors 0 and 1, could dedicate sector 2 to bootloader-specific configs, and sector 3 to application-specific configs.

Probably use something like TicKV from Tock for a kv store.
