Add a package which deploys the NXP MC (Management Complex) firmware to the target. This is necessary for NXP DPAA2 SoCs (LS1088A, LS2080A, LS2088A, LX2160A). The MC firmware is deployed by default to the $O/images/ folder, where it can be used by post-build scripts. Additionally, if BR2_PACKAGE_QORIQ_MC_BINARY_TARGET_INSTALL_PATH is specified and if the board mcinitcmd is written as such as to pick it up, it is optionally deployed to the filesystem. The API exposed by the MC firmware respects backwards compatibility principles, which means that the latest firmware version can always be (and should always be) used on a platform, irrespective of the Linux, U-Boot, RCW and restool versions, even though the latest features might not be used by older API consumers. In terms of forwards compatibility, old MC firmware versions can be used as long as the qoriq-restool package is built with a MC_VERSION_COMPATIBLE variable (located in its Makefile, signifying "minimum compatible version") older than, or equal to it. If the use of qoriq-restool is not desired (networking objects are statically created by the DPL), old MC firmware versions are supported by U-Boot and the Linux kernel with a limited feature set. Thus, it is still possible to an extent to use firmware versions older than MC_VERSION_COMPATIBLE. According to the upstream maintainer, the latest MC firmware version is identified by the fact that it is always located at the HEAD of the "master" branch: https://lore.kernel.org/buildroot/482493f17e63d2b4cb285b50049ed8e6@free.fr/T/#m62c3ec04ba546ac9b0a194d13bc35fedeaa9deb0 Currently, the latest MC firmware version is 10.39.0. This version should be in sync with the qoriq-mc-utils package. At this stage, the latest lf-6.12.3-1.0.0 NXP BSP has qoriq-restool with an MC_VERSION_COMPATIBLE='10.32.0', which means that it supports this MC firmware version. https://github.com/nxp-qoriq/restool/blob/lf-6.12.3-1.0.0/Makefile#L23 Note that the MC firmware also used to be distributed through linux-firmware: https://web.git.kernel.org/pub/scm/linux/kernel/git/firmware/linux-firmware.git/tree/dpaa2/mc?h=20250311 I don't know what was the reason for doing that, but it stopped being updated and the versions there are quite old.

The Management Complex (MC) is a key component of the

|
networking subsystem named DPAA2 (Data Path Acceleration
|
|
Architecture, second version) in some NXP Layerscape SoCs.
|
|
|
|
The MC coprocessor runs a closed-source, NXP-supplied
|
|
firmware image that simplifies and abstracts the allocation
|
|
and configuration of the networking hardware primitives into
|
|
DPAA2 "objects".
