Can you create a separate file named at91-kstr-sama5d27-u-boot.dtsi (
which is automatically included by the Makefile) which would contain the
bootph properties
(Have a look at arch/arm/dts/at91-sama5d29_curiosity-u-boot.dtsi for
example )
In theory we would like the board dts file to be identical with Linux (
as much as possible if not identical ), and have specific U-boot props
in such a separate file.

Which bus number (in Uboot) is this i2c6 being assigned to ?
Would it be better , and/or more predictable to add an alias to the
desired bus number in DT ?
e.g. aliases { i2c2 = &i2c6; }
Thanks,
