[PATCH v2 0/2] ARM: dts: bcm5301x: Add BCM SVK DT files

[PATCH v2 0/2] ARM: dts: bcm5301x: Add BCM SVK DT files

[Jon Mason]

This patch series adds the device tree files for the Broadcom Northstar based SVKs.  

Changes in v2:
* Reorder the patches to add the DT binding documentation prior to the new DT files
* Removed the DT documentation compat strings to only the SoCs, not the individual boards
* Fixed the compat strings in the individual device tree files
* Added the memory node and removed the "mem=" from the bootargs

Thanks,
Jon

[PATCH v2 1/2] dt-bindings: Add new boards to bcm4708 DT bindings

[PATCH v2 2/2] ARM: dts: bcm5301x: Add BCM SVK DT files

[Jon Mason]

Add device tree files for Broadcom Northstar based SVKs.  Since the
bcm5301x.dtsi already exists, all that is necessary is the dts files to
enable the UARTs (and specify the RAM size for the 4708/9).  With these
files, the SVKs are able to boot to shell.

I assume this is a bcm4709 SoC, then you should used this line:
compatible = "brcm,bcm94709", "brcm,bcm4709", "brcm,bcm4708";

If you would put these device tree files into the bootloader and we
would have to do an workaround for all bcm4709 SoC, but nor for the
bcm4708 Soc Linux would be able to detect this.

What is the difference between bcm53012 and bcm4708?

Currently we have the bcm4708.dtsi and the bcm47081.dtsi file one is for
dual core SoCs and the other for the single core versions, does one of
them fit BCM953012K, then you should include it?

I assume this is a bcm53012 SoC and a BCM953012K board, then you should
used this line:
compatible = "brcm,bcm953012k", "brcm,brcm53012", "brcm,bcm4708";

I thought we wanted to add the SoC names here, isn't bcm94708 a board
the bcm4708, the SoC ion this board? I do not really care about this
file, has anyone found the documentation what should be listed here?

One additional question. What flash are you using on these boards? For
some common NAND flash properties you only have to include
bcm5301x-nand-cs0-bch8.dtsi or do these boards use serial or parallel flash?

Yes - the 9 infront indicates its some type of board.  The SoC part 
numbers should be listed here.  The SoCs are all variants of 
Northstar/Northstar plus family.  Some have different io, packaging, 
speed grades, etc.

To be honest, I haven't gotten far enough to investigate that.  I am
assuming that it is "brcm,nand-iproc" like NSP (which is different
than the file you reference).

It uses brcm,nand-iproc, but this driver also needs some information

bcm5301x-nand-cs0-bch8.dtsi.

There are single and dual core variants of bcm5301X.  With the single
cores being bcm53010 and bcm53014, and bcm53011/2/5/6 being dual.
Much like the bcm4707 and bcm47081 being single, and 4708 and 4709
being dual.  So, this should include bcm4708.dtsi.

As an aside, it would make much more sense to have bcm4708.dtsi be
named bcm-ns-smp.dtsi (as these are variants of the Northstar SoC) or
bcm4708-smp.dtsi.

If it is alright with you, I'll investigate, add, and test this after
these initial changes get it.
