31c41b7d9e Drop I2C bit functions, to make timing easier to modify 
I2C to the charger now has clean 100kHz timing. One read command now takes
400us, and one write command takes 300us to execute.

0e4f426dfb Add bin2pgd tool 
This is used by the vendor's flashing tool. It's ROM image + option
ROM image appended (256 bytes).

Option ROM contains some flags and configuration data for the MCU.
Things like oscillator configuration, HW reset pin enable, data EEPROM
enable, etc.

3c6488b99e Disable I2CA in all firmware builds

3107546c04 Revert "firmware: Make interrupt signal shorter (10us)" 
The longer duration is actually required, likely due to debouncing
applied on the SoC side. Even 50us was unreliable.

This reverts commit 3b723583e7.

394af632aa firmware: Allow to read/write single registers from a charger 
This code uses existing system command functionality. The I2C
registers are placed in front of system command register, to
allow for a single transaction proxied I2C A reads/writes.

Not tested, yet.

c3272eb4ef firmware: Drop POLL mode from the register definition 
Polling mode was supposed to help with broken keyboard matrix, where
some keys are stuck, but this is handled well by the pre-existing code
already, so there's no need for this.

bd69a00f7a common: Improve crc8 generation 
Start with 0xff instead of 0x00, so the CRC will be nonzero (and length
dependent) for data that is all zeroes.

Remove unnecessary masking, since `crc` is already an 8-bit integer.

2fbc2e057e firmware: Implement scanning block 
This allows to disable the keyboard. The firmware will never scan
for keys pressed in this mode, and it will powerdown the MCU most of the
time.

cea046008f Increase the default flashing area size to 0x2000 
This does two things:
- more reasonable default because stock firmware size is larger than
  the previous default
- it will overwrite 0x3fff with 0xff, so that after flashing stock
  firmware the user firmware is automatically disabled

6a5fe581b9 Implement flashing over I2C and user/stock firmware support 
I2C register layout changed a bit to make various operations easier
to implement in FW and for the user.

Flashing/debugging tools now share more code. Firmware is now more
configurable (it's now possible to compile-out various features).

Self-testing for column-shorts is implemented.

Firmware is optimized for low power consumption.
