[PATCH 0/2] Freescale T1040RDB DTS updates

[Vladimir Oltean]

This contains a fix for the new device tree for the T1040RDB rev A
board, which never worked, and an update to enable multiple CPU port
support for all revisions of the T1040RDB.

[PATCH 1/2] powerpc: dts: t1040rdb: fix compatible string for Rev A boards

[Vladimir Oltean]

It looks like U-Boot fails to start the kernel properly when the
compatible string of the board isn't fsl,T1040RDB, so stop overriding it
from the rev-a.dts.

[PATCH 2/2] powerpc: dts: t1040rdb: enable both CPU ports

[Vladimir Oltean]

Since commit eca70102cfb1 ("net: dsa: felix: add support for changing
DSA master") included in kernel v6.1, the driver supports 2 CPU ports,
and they can be put in a LAG, for example (see
Documentation/networking/dsa/configuration.rst for more details).

Defining the second CPU port in the device tree should not cause any
compatibility issue, because the default CPU port was &seville_port8
before this change, and still is &seville_port8 now (the numerically
first CPU port is used by default).
