[Qemu-devel] [PATCH v5 00/28] block/pflash_cfi02: Implement missing AMD pflash functionality

[Philippe Mathieu-Daudé]

Hi,

This series is based on Stephen Checkoway work (v4):
https://lists.gnu.org/archive/html/qemu-devel/2019-04/msg04595.html

Stephen work is a great improvement of the actual code, however
while reviewing his patches, I found them quite dense, so I started
to split each logical change to be able to digest his series.

Sfephen implemented the 'interleaving' feature in way I am not yet
confident it is in the project best interest. The relevant thread
started here:
https://lists.gnu.org/archive/html/qemu-devel/2019-06/msg05395.html

However meanwhile we will discuss his interleaving implementation,
I don't want to block the rest of his work, so I took that patch
of (and rebased his work).

I'm spamming all the maintainers of the boards using
pflash_cfi02_register(). This series is not 'block' related, it is
a classical 'device' model series.
Help reviewing is appreciated :)

I am still looking for real-world code stressing this flash model.

Regards,

Phil.
