Kernel moving to Linux v5.10, dropping PECI

[Joel Stanley]

The openbmc kernel will move to a 5.10 based tree for Aspeed and
Nuoton machines.

    linux-openbmc: Move to Linux 5.10

    This moves the OpenBMC kernel to a v5.10 base for both Aspeed and
    Nuvoton. There are 125 patches in the tree, with 80 of those patches not
    yet queued for merging in v5.11.

    Notably the PECI patchset has been dropped as the author, Intel, has
    elected to develop it out of tree instead of submitting it for mainline
    inclusion.

Regarding the PECI situation, I raised it on the list back in August.
The conversation finished up in October with a commitment that the
work would be done as soon as possible.

This kernel config option is enabled by machines from Facebook,
Bytedance, HPE, Lenovo, Quanta and Supermicro. (Surprisingly Intel
doesn't enable it on their platform?). It would be great for someone
from one of those teams to step up and submit the PECI patchset
upstream.

In the meantime these in-tree systems will regress their PECI support
until the patchset is submitted to mainline.

Cheers,
