Hej,
this series adapts Sven's Linux nvme-apple series of the same name to
u-boot. It fixes bugs which are worked around on M1/M2/M3 based devices
with NVMe firmware from macOS 14.x or earlier. Starting with the NVMe
controller firmware from macOS 15.x (required for M4 support) the
workaround is no longer available.
The quirk to require page-aligned buffers for the admin queue is not
necessary for u-boot. As far as I can see the buffers are always
page-aligned. Add noisy WARN_ON_ONCEs to ensure it's noticed if this
changes or I was mistaken to begin with.
Do you want to pick those changes or should I route them via the NVMe custodian
?
Thanks,
Neil
Janne
