@ServError, since your patch is more complete, do you want to update this one? You would do that by using "DOWNLOAD" button to pull it locally, rebasing/amending the patch and then pushing it back via `git push {URL} HEAD:refs/for/master`. If not, I can combine patches myself and will put `Signed-off-by:` to give credit to you.

Thank you for help! Will wait for your response then.
With the patches, all patches need to go through Gerrit. Even if patch is sent by ML, someone needs to push it to Gerrit.
This one already created, so someone needs to rebase and push a new patchset to finish it. If that new patchset will be done by another contributor, they add a second Signed-off-by line.

I asked about it on Friday, waiting for a response after the work week begins. The ML patch looks more complete to me so far.

PS1:
> I couldn't figure out whether this got here for a good reason. […]
I checked the unlock functions, it turns out one of them actually does unlock for reads (last bullet).
Most unlock functions call `spi_disable_blockprotect_generic()`, which only tries to clear bits in SR1. I've never seen a chip with SR1-controlled read protection, chips that do have read protection usually control it via special registers or command sequences. So these are probably safe.
There are four unlock functions that don't call `spi_disable_blockprotect_generic()`:
- `UNPROTECT_28SF040` - used by SST28SF040A - I don't have datasheet, it looks like a very old parallel flash. I would guess it doesn't have read protection.
- `UNLOCK_SST_FWHUB` - used by several chips - the SST49LF0008A datasheet doesn't indicate it has read protection.
- `SPI_DISABLE_BLOCKPROTECT_AT45DB` - used by several chips - the AT45DB321E
datasheet doesn't indicate it has read protection.
- `SPI_DISABLE_BLOCKPROTECT_SST26_GLOBAL_UNPROTECT` - used by several chips - according to the SST26VF032B datasheet, there is sector based read and write protection that can be globally cleared with a ULBPR (98h) instruciton, which is what the unlock function does.
Maybe we can work it around with something like a `FEATURE_UNLOCK_FOR_READ` chip flag?

PS2:
Thanks Joseph! You need to add a comment about model id (see my comment below) and that should be it.
File flashchips.c:
https://review.coreboot.org/c/flashrom/+/68278/comment/cf3534cd_d620473b :
PS2, Line 8772: MACRONIX_MX25L1605
> Nope, it is 0x2015 since the RDID command is used (probe_spi_rdid, see page 20).
Thanks for explaining! I agree.
Why I was initially confused is that ID MACRONIX_MX25L1605 from another chip is used. You need to add a comment to include/flashchips.h that this id also serves MX25V16066 (there are lots comments like this as examples).
https://review.coreboot.org/c/flashrom/+/68278/comment/637da7c1_d2333141 :
PS2, Line 8802: 2700
> yep, 2.3V-2.7V works, but at a slower speed. […]
I see, thanks!

Thank you Ao, I checked the patch, all good! I have just one comment about commit message and that would be it.
