The main question is: how should liteSOM sources be integrated? I didn't
find similar modules, which are part of different boards in u-boot
tree. For now, I've put source into arch/arm/mach-litesom, but I guess
it is not the best place for them.


What about placing it inside board/grinn/ ?


Putting them in board/grinn/ was my first idea (adding them to
board/litesom/). Unfortunately there is no easy way to build those
sources there.

Board sources are built depending on vendor and board name. As litesom
will never be a board name, these sources won't compile.

Additionally there is a possibility to add "common" directory inside
vendor directory (so there would be something like 
board/grinn/common/litesom/). This will work for all grinn boards. But 
the idea is

that some other vendor can make a board that will use litesom. And in
that case sources from board/grinn/ directory won't compile.

So my idea was to treat SOM go rather like SOC which is in arch/, than
BOARD.

Please rebase against U-Boot 2016.09. There are new fields now: refsel and refr.



Thanks for noticing.

[U-Boot] [RFC] board/liteboard: Add support for liteSOM and liteBoard

2016-08-31 Thread Marcin Niestroj 
liteSOM is a System On Module (http://grinn-global.com/litesom/). It
can't exists on its own, but will be used as part of other boards.

Hardware specification:
 * NXP i.MX6UL processor
 * 256M or 512M DDR3 memory
 * optional eMMC (uSDHC2)

liteBoard is a development board which uses liteSOM as its base.

Hardware specification:
 * liteSOM (i.MX6UL, DRAM, eMMC)
 * Ethernet PHY (id 0)
 * USB host (usb_otg1)
 * MicroSD slot (uSDHC1)

The main question is: how should liteSOM sources be integrated? I didn't
find similar modules, which are part of different boards in u-boot
tree. For now, I've put source into arch/arm/mach-litesom, but I guess
it is not the best place for them.

The patch below compiles and runs successfully on liteBoard. It is based
on 2016-09-rc2.
