[PATCH 0/2] board/raspberry: add FDT for bcm2712d0

[Filip Kokosiński]

This series adds the FDT for the d0 stepping of the BCM2712 SoC. The v1.1
revision of the Raspberry Pi 5 board can't boot Linux properly without
additional changes specific to the d0 stepping.

The d0 specific changes can be seen here:
https://github.com/raspberrypi/linux/blob/rpi-6.12.y/arch/arm64/boot/dts/broadcom/bcm2712d0-rpi-5-b.dts

To do that, this series introduces support for multiple FDT entries for a single
device type (bits 4-11 from the new-style revision code).

The rpi_model struct is modified by:
* changing fdtfile to fdtfiles (const char * const *)
* adding fdtcount (size_t)

Adding fdtcount is motivated by wanting to keep FDT selection O(1), and avoid
relying on NULL terminating fdtfiles array.

A new FDTFILES macro is added to initialize fdtfile and fdtcount.

In case only a single FDT is provided, or the board revision code doesn't match,
the selected FDT defaults to the first entry in fdtfiles.
