Change in flashrom[master]: buspirate_spi: Add support for variable serial speeds
by Shawn Anastasio (Code Review) 02 Jan '18

02 Jan '18

Shawn Anastasio has uploaded this change for review. ( https://review.coreboot.org/23057 Change subject: buspirate_spi: Add support for variable serial speeds ...................................................................... buspirate_spi: Add support for variable serial speeds This patch introduces the ability to set the baud rate for communication between the host device and the Bus Pirate via the added 'serialspeed' programmer parameter. This is done in two parts. Firstly, the requested serial speed is looked up in a table to determine the appropriate clock divisor and the divisor is sent to the bus pirate. Then, the system's baud rate for the selected serial port is set using serial.c's 'serialport_config'. This function's prototype had to be added to programmer.h. In testing, using the 2M baud rate was able to significantly decrease flash times (down from 20+ minutes to less than 2 minutes for an 8MB flash).
