v4: - utilize EVT_SETTINGS_R in order to read MAC and serial number from EEPROM
v3: - use CONFIG_ID_EEPROM to read serial number - as side-effect of using CONFIG_ID_EEPROM, KSTR-SAMA5D27 now also correctly uses EEPROM embedded MAC addresses (overlooked in v1-v2) - use CONFIG_DISPLAY_BOARDINFO_LATE for printing the board model and serial number, and provide the required checkboard() call - drop CONFIG_BOARD_LATE_INIT, as not needed anymore - defconfig cleanup
v2: - remove redundant license text from at91-kstr-sama5d27.dts - when defining properties in .dts, reference nodes by labels - drop nodes for usb0 and pmic, as these aren't used by drivers - switch i2c to flexcom driver and make the necessary dts changes - sort includes in at91-kstr-sama5d27.dts alphabetically

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, Eugen
