Guys,
Let get back to the original thread. Since Rajat's first reply, the message id has been changed. All the comments were not captured by patchwork.
I also wondered about this. Seems to have happened at some top-posting quite at the beginning of this thread.
I am having trouble recently with office365. It seems breaking all my email threads if senders use outlook.
From what I read, Rajat's method is to extend the controller driver to support read SFDP and default to 4-byte mode if supported, or overwritten by user's flag. Stefan's method is to read 4-byte status bit and doesn't change controller driver.
Yes, the last sentence it correct.
Is the default value of this 4-byte status bit valid and correct for all cases?
This 4-byte address status bit implementation is SPI NOR chip specific (vendor specific?). With Simon's help we already support 2 vendors now. Extending for other vendors / chips is fairly easy.
Let's wait for Rajat's comment. If this method doesn't work for his boards or his controllers, he still needs to extend controller's driver feature.
