> Further explanation of the reasons for this change: […]
Sorry, I'm not convinced. This looks like a workaround for something only downstream uses.
However, I agree that having to deal with multiple flash chip definitions is annoying. If what downstream needs is to ignore one of the flashchip definitions, why not add a command-line argument to specify flashchip entries to ignore? It would have the same semantics as `-C`. This feature would be useful for everyone, not just downstream.

The processing time is negligible. Just prefix your flashrom
command with `time`, you'll see that it actually does nothing
but waiting in either case.
If you could provide a total number how long it takes to fully
read/erase/write a chip, that could give us a clue (sorry if
this was already given and I missed it). I suspect the VM case
to be slower in general, so the speed increase of this patch
would just be time re-gained that was lost due to the virtuali-
zation in the first place. So far my theory.
I expect, but don't know, the individual packets to reach the FTDI
with some delay. I have not looked into libftdi deeply enough. Maybe
it waits for confirmation that the write reached the device before
ftdi_write_data() returns. If this is the case, we'd get a lot syn-
chronization overhead. Consider this:
send WREN packet -->
send WP packet -->
wait for acks <--
vs.
send WREN packet -->
wait for ack <--
send WP packet -->
wait for ack <--
Ignoring bandwidth, in the second example, it would take 2 round-
trip times instead of one. And the round-trip is influenced by the
virtualization. It depends a lot how the lower layers are implemen-
ted. What flashrom leaves to libftdi.
>
> Feel free to comment if you think this patch is worth to get merged.
I think it's nice work and even if it wouldn't ever increase the speed,
it would still be a nice example how to implement spi_send_multicommand 😊
But that it helps your use case without affecting others would be enough
reason to get it in anyway.
From my side, I'll just have to find the time for a final good look at
it, then it could be merged.

PS1:
Further explanation of the reasons for this change:
These chip entries are some of the last differences between cros and upstream flashrom - resolving them will get us extremely close to fully deforking the flashchips.{c,h} files.
We also tried bringing the duplicate chip into cros flashrom, but that caused issues with flashchip identification, and resolving it would be likely to significantly delay resyncing flashchips.c.
This patch does remove the FEATURE_QPI feature bit (since only 'C' chips had it), however (AFAIK) that feature flag is currently unused, and the chip's capabilities are still recorded in the comments. An additional advantage of this approach is that it generally makes flashrom easier to use.

OK, I understand (I have/had got no idea of VM stuff).
So in case of not using VM, the speed we gain because of less USB communication is consumed by the increased processing time needed to pack the packages?

Hello build bot (Jenkins), Alan Green, Nico Huber, Edward O'Callaghan, Angel Pons, Anastasia Klimchuk, Samir Ibradžić,
I'd like you to reexamine a change. Please visit
https://review.coreboot.org/c/flashrom/+/40477
to look at the new patch set (#33).
Change subject: ft2232_spi.c: Implement spi_send_multicommand()
......................................................................
ft2232_spi.c: Implement spi_send_multicommand()
Every ftdi_write_data() call is quite time consuming when using flashrom
inside a virtual machine. This leads to what the comment already says:
Minimize USB transfers by packing as many commands as possible together.
This saves about 1 minute when programming a 128MBit Flash with my
VM config!

private from the libflashrom API, as in "internal" to the flashrom implementation. Not to mean static local. private is a bit of a overloaded term [sic. java/c++].
