#### ECP5 specific ####
ECP5_DEVICE=25F
# ECP5_DEVICE: 25F: Create bitstream for the LFE5U-25F
# 85F: Create bitstream for the LFE5U-85F
ECP5_PACKAGE=CSFBGA285
# ECP5_PACKAGE: CSFBGA285: The one used in OrangeCrab
Build system: Improved the handling of seeds, moved most of the board specific build instructions to the board specific .mk file and fixed bios.asm dependencies

Peripherals/I2C: Added a CPU I2C driver and wrote a bootloader that uses that to boot from an I2C eeprom I'm happy to have reached 200 commits and with this, version v0.3.0 is functionally ready. I still need to do a fair bit of cleanup and bug fixing though before the actual release. With this commit I added a CPU I2C driver as well as a basic arbiter to have the hardware lcd controller and the software i2c communication pass through the same I2C driver and I2C bus. I also wrote a bootloader that reads code from an i2c eeprom to make sure the hardware works.
