Add an initial device tree for Qualcomm RB2 board (see [1]).
Currently it enables:
- eMMC via SDHC1,
- uSD card via SDHC2,
- RPM regulators,
- Debug UART (via micro USB port).
Subsequent patchset(s) will add more peripherals like USB, etc.
To get a successful boot run:
$ cat arch/arm64/boot/Image.gz arch/arm64/boot/dts/qcom/\
qrb4210-rb2.dtb > ./Image-adp.gz+dtb
$ mkbootimg --kernel ./Image-adp.gz+dtb \
--ramdisk ./some-initramfs-image.rootfs.img \
--output ./rb2-boot.img --pagesize 4096 \
--base 0x80000000 --cmdline 'SOME_CMDLINE'
$ fastboot boot ./rb2-boot.img
