[Buildroot] [PATCH] configs/imx6ullevk_defconfig: bump Linux to 6.6.4 and U-Boot to 2023.10

[Giulio Benetti]

Let's also enable NXP firmware package to let latest SDMA firmware to be
loaded. To achieve this we also need to enable dynamic eudev to let it
to load the firmware.

Why is that? I thought request_firmware() nowadays didn't need any help
from user space to fetch files from /lib/firmware?

Is it because this is requested very early before the rootfs is mounted?

Exactly, if the driver is built-in Linux it's too early to search rootfs
because it's not mounted.

Of course during drivers' probe()s and all kernel calls using dma will
use ROM SDMA Firmware until SDMA Firmware is loaded from rootfs so those
calls will have worse performances.
Of course NXP Firmware can't be embedded into Linux because it's
proprietary and license doesn't allow us to do that.

Kind regards

OK. Committed after extending the commit message to explain that, thanks.
