726e6e62fa armcm_boot: No need to reset cpu state on bootup 
The bootloader is only called after a reset - it doesn't need to worry
about another bootloader launching it.  This reduces the code size by
a small amount.

34e14386ed Makefile: Build with -Os instead of -O2 
Build size is likely more important than CPU performance for a
bootloader.  So, instruct gcc to optimize for size by default.

794ccd69c0 canbus: Use Klipper's nodeid to canbus_id scheme 
Use Klipper's nodeid to canbus_id scheme (canbus_id = nodeid * 2 +
0x100).  Instead, use a nodeid offset of 128 to avoid collisions with
Klipper.
