Change in flashrom[master]: it87spi.c: Move singleton state into spi master state tracker
by Edward O'Callaghan (Code Review) 23 Nov '20

23 Nov '20

Edward O'Callaghan has uploaded this change for review. ( https://review.coreboot.org/c/flashrom/+/47662 ) Change subject: it87spi.c: Move singleton state into spi master state tracker ...................................................................... it87spi.c: Move singleton state into spi master state tracker Make use of the reneterent framework by moving singleton static state out of the global life-time and into a per-spi_master basis. This allows for the it87spi master to be reneterent and its internal state's life-time to be correctly handled by Flashrom's core dispatch logic.

Change in flashrom[master]: ft2232_spi.c: Pack WREN and op in one ftdi_write_data() call

Hello build bot (Jenkins), Angel Pons, I'd like you to reexamine a change. Please visit https://review.coreboot.org/c/flashrom/+/40477 to look at the new patch set (#21). Change subject: ft2232_spi.c: Pack WREN and op in one ftdi_write_data() call ...................................................................... ft2232_spi.c: Pack WREN and op in one ftdi_write_data() call Every ftdi_write_data() call is quite time consuming as the ftdi-chips seems to take always 2-3ms to respond. This leads to what the comment already says: Minimize USB transfers by packing as many commands as possible together. So I packed the WREN command together with the following operation which can be program or erase operation. This saves about 1 minute when programming a 128MBit Flash with my config! I´m using ftdi-2232H chip. That´s why I put it at this place. If anyone has a good overview about all programmers: This could be implemented in spi_write_cmd() in case that it is compatible to all programmers or this principle could be transfered to other programmers which act in a similar way.
