A substantial cleanup on CBMEM initialisation is now under review. Goal is to get timestamps and CBMEM console supported on more/most mainboards, but I do not expect to complete this during the official GSoC period, or within the next two weeks time.
One of the goals I originally had set was to have means to re-program the flash chip from pre-OS environment. It is now clear I will not have time to finish (or even start) this part of the project. The decision to delay this part was made quite early on, actually. I learned similar work had already been developed as a combination of FILO+libflashrom, and I hope Stefan’s efforts on another GSoC project will help get this code published in near future. I might still try to get the FILO console appear over usbdebug, adding support of USB communication class (CDC / ACM) in libpayload should not be very difficult.
I have saved some of the most interesting and challenging parts last: having SerialICE and GDB run over usbdebug. Hopefully I get to report about those next week.
