Hello Paul Menzel, build bot (Jenkins), I'd like you to reexamine a change. Please visit https://review.coreboot.org/26948 to look at the new patch set (#4). Change subject: programmer: Add Developerbox/CP2104 bit bang driver ...................................................................... programmer: Add Developerbox/CP2104 bit bang driver The 96Boards Developerbox (a.k.a. Synquacer E-series) provides a CP2102 debug UART with its GPIO pins hooked up to the SPI NOR FLASH. The circuit is intended to provide emergency recovery functions without requiring any additional tools (such as a JTAG or SPI programmer). This was expected to be very slow (and it is) but CP2102 is much cheaper than a full dual channel USB comms chip. Read performance is roughly on par with a 2400 baud modem (between 60 and 70 minutes per megabyte if you prefer) and write performance is 50% slower still. The full recovery process, with backup and verification of 4MB data written takes between 14 and 15 hours. Thus it is only really practical as an emergency recovery tool, firmware developers will need to use an alternative programmer.
