Re: [U-Boot] [PATCH] spi: Add support for MX66U51235F, MX66L1G45G and MT25QU02G

[Bacrau, Dumitru]

Hi Teki,

Sure, I can do that, but here is more information, maybe we can come up with a 
better solution:

For this device, the "U" in the part name means "1.8V". The equivalent 3.3V 
part has "L" in the part name. So I would prefer having the names:
 - MT25QL02G - for 3.3V device
 - MT25QU02G - for the 1.8V device

The advantages of this naming is that the string is easily searchable on the 
web (for example if you search for N25Q1024 you will not find it on the Micron 
website).

If that is not acceptable, then I would suggest the following alternative 
(without 'U' or 'L'):
- MT25Q02G - for 3.3V device
- MT25Q02GA - for the 1.8V device

Just let me know which one you prefer, and I will re-submit. I can include the 
3.3V part according to datasheet, although I cannot test it.

Thank you,
Radu

Since it's bb 1.8v we usually differentiate to use 'A' at the end of the name 
like
N25Q1024 - 0x20ba
N25Q1024A - 0x20bb

So, we need append A at end of the name - MT25QU02GA. If you agree please try 
to send the next version with this update.

thanks!

[Bacrau, Dumitru]

Hello Teki,

The device that I have used is MT25QU02GCBB8E12-0SIT, with the datasheet 
available here: 
https://www.micron.com/~/media/documents/products/data-sheet/nor-flash/serial-nor/mt25q/die-rev-b/mt25q_qlkt_u_02g_cbb_0.pdf.
 

Thanks a lot,
Radu
