Kevin O'Connor	8a203cf2cb	rp2040: Move chipid reading to bootrom.c ... Rewrite chipid.c so that it contains just the USB and canbus id manipulation code. Move the low-level chipid reading to bootrom.c. Also, introduce a new bootrom_reboot_usb_bootloader() function in bootrom.c so that the main.c code does not need to know the specifics of rebooting into the bootrom.

Lasse Dalegaard	ba958468b7	rp2040: add chipid support ... The rp2040 doesn't have a chip ID, but the flash chip connected does. We can get this ID by asking the flash chip directly, but doing so requires disengaging the XIP layer, performing the interrogation of the flash chip, and then re-enabling the XIP layer. This gives us a 64-bit unique ID that we can use as our USB serial number. Signed-off-by: Lasse Dalegaard <dalegaard@gmail.com>	2021-07-04 12:43:45 -04:00
