[PATCH 00/20] Enable DM_SERIAL for NXP PPC T-series boards

[PATCH 00/20] Enable DM_SERIAL for NXP PPC T-series boards

[Camelia Groza]

This series enables DM_SERIAL for t2080rdb, t4240rdb, t1042d4rdb and
t1024rdb.

Similar steps are taken for each board:
- The get_serial_clock() callback is implemented for each board
- The serial nodes are described in the device tree, similar to Linux v6.4
- The serial nodes are marked with 'bootph-all' to guarantee the drivers
are initialized before relocation. New board specific *-u-boot.dtsi files
are created to store these properties.
- CONFIG_DM_SERIAL is enabled in the board defconfigs

While here, enumerate the PCI devices at probe time for each board.

[PATCH 12/20] board: freescale: t104xrdb: implement get_serial_clock

[Camelia Groza]

The serial clock is provided by the get_serial_clock() callback on PPC
under DM_SERIAL. Use the same method to compute the clock as for
non-DM_SERIAL use cases.
