W25Q256JV_Q is checked

hi,

I checked the PROBE - READ - ERASE - WRITE operations of the W25Q256JV_Q 
flash with J-Link and CH341 spi writers.
the flashrom version was the newest development release at 2025-04-14 
(#4d4688ccf132c580107b013d2d929a0816aa89c1)
I made a little modification in the 'jlink_spi.c' source, because I use 
the power supply from the J-Link device pin 19.
this power is 5V, I put a 3.3V LDO (HT7333) after it, and this LDO (and 
decoupling capacitors) need more time to fix output voltage.
I attached the patch file.
[ I tried to ask merge request via Jenkins, but it was too complicated 
for modify one char in the source ;-) ]

my flash type was Winbond 25Q256JVEQ, which recognized by flashrom to 
W25Q256JV_Q or W25Q256FV, both type probed, read, wrote, erased, both 
modality worked fine.

Hello Attila,

Thank you so much for reporting all the testing details and logs, this
is very useful!

Is this your patch that you sent some time ago
https://review.coreboot.org/c/flashrom/+/86085 ? I was wondering why
you disappear after sending the patch :)

There are two things in your message:

1) You have successfully tested W25Q256JV_Q which previously has
untested status. I updated the test status of this chip and added a
Tested-by tag with your name, are you alright with that? Hopefully
yes, if you could +1 the patch
https://review.coreboot.org/c/flashrom/+/87459 it would be great! I
copied your name and email from your patch that you sent earlier, see
below:

2) About your earlier patch
https://review.coreboot.org/c/flashrom/+/86085 what do you think can
it be useful for other people (flashrom users) too? I understand that
you needed a longer delay in your setup, this could be a programmer
param to customise the delay - depending on how unique or common this
setup is.

You created the patch successfully! :) But then, we always have code
reviews and sometimes a patch can be modified in the process of
review.
