This patch add support for one device of the Bachmann OT1200 series - the mr variant.
Nobody knows (at least, me !) what mr variant means.
its just a project name.
My first attemp was to use one u-boot binary for all OT1200
^----attempt
ups
devices, but as I need to load a device-specific devicetree I decided to go this way.
but a specific devicetree for kernel means only a different U-Boot variable in the environment ? Sure that we are not able to manage this ?
That is correct... in the beginnings we did not stored the env in the SPI flash but only used the default one. But that looks like a very good idea. So I can get rid of CONFIG_SYS_VARIANT and have really only one u-boot image for all two devices :)
Following components are used:
- ethernet
- usb
- i2c
- display connected via ldb (init and usage in linux only)
- emmc

as setup_spi set only the iomux, and you set the whole iomux in board_early_init_f(), why do you need to postpone the setup in boar_init() ?

There also CONFIG_SYS_BOARD_NAME, near CONFIG_SYS_BOARD. Having both is misleading, I think we have to clean it up. But boards define CONFIG_SYS_BOARD_NAME, that is a more descriptive name.
