PATCH [0/4] Add support for Emerson ATCA-C125 board

[Alexandr Smirnov]

Hi all,

The following sequence of patches intended to add support for Emerson ATCA-C125
board.

Thanks,
Alexandr

[PATCH 1/4] Emerson ATCA-C125 bootwrapper

[Alexandr Smirnov]

Bootwraper for Emerson ATCA-C125 board. This board has
four ethernet ports, so it has to use this code instead
of generic.

Since this is a new board, couldn't you name the soc node /soc and
dispense with this more complicated way of doing things?  Or would
that break other versions of u-boot that are in use?

As I understand you would like to rename /soc8548 node to /soc and make 
a simple path lookup like following:
- soc = find_node_by_devtype(NULL, "soc");
+ soc = finddevice("/soc");
Is this correct?

But fsl_soc code still uses of_find_node_by_type so we can't remove 
device_type property from node /soc and therefor simplify device tree.


Thanks,
Alexandr

That's right.

It does?  Grrr...  I thought that had been fixed and the only reason
the device_type was still needed was because some u-boot versions
needed it.  But you're right, that's not the case.

[PATCH 4/4] Emerson ATCA-C125 base support

[Alexandr Smirnov]

The ATCA-C125 is a single-slot Advanced Telecom Computing Architecture
(AdvancedTCA®, ATCA™) carrier with up to four Advanced Mezzanine Cards
(AdvancedMC) expansion modules. This expansion capability enables a wide
variety of control and packet processing applications such as WAN access,
traffic processing, signaling gateways, media gateways, and many others.

The board has altera maxii CPLD, that is used to obtain and manage board
configuration.
