## Global

- improve error message (be more precise)
- catch all exception
- documentation (code + API)

## Cable

- fix *ch552* (*Sipeed tangNano*): works with *SRAM*, fails with *Flash*
- *busblaster* support
- *anlogic* cable support

## Devices/boards

- improve frequency configuration. Use FPGA, cable or --freq args maximum frequency
- rework *cyclone10* eeprom access to avoid using FT2232 interfaceB Spi
  emulation (only supported by trenz board)
- fix checksum computation with *gowin GW2A*
- add support for *tangPrimer* (*anlogic EG4S20*)

## Misc

- fix spiFlash class to be able to write everywhere (currently offset is hardcoded
  to 0)
