[Michal Simek]

Hi,

and I forget to mentioned. Use mainline mailing list instead of xilinx one.

Thanks,
Michal

Then this shouldn't be the part of this file. picozed is SOM and you
should describe all stuff which are just on this module.
If you want to support Picozed with any carrier board you should
describe it separately. The best carrier and include picozed dts.

checkpatch is not designed to parse DTS files and I am not sure if there
is any parser.

[U-Boot] [PATCH] ARM: zynq: Extend picozed board support

[Oscar Gomez Fuente]

Ok Michal,

Then you're suggesting change the zynq-picozed.dts file to:

diff --git a/arch/arm/dts/zynq-picozed.dts b/arch/arm/dts/zynq-picozed.dts
index 3408df8..d8ed298 100644
--- a/arch/arm/dts/zynq-picozed.dts
+++ b/arch/arm/dts/zynq-picozed.dts
@@ -14,6 +14,8 @@

        aliases {
                serial0 = &uart1;
+               spi0 = &qspi;
+               ethernet0 = &gem0;
        };

        memory {

+};

And add a new dts file with the configuration of the PizoZed FMC Carrier V2
(in this case V2. Avnet has two PicoZed FMC carriers V1 and V2). For
example: zynq-picozed-fmc-v2.dts

#include "zynq-picozed.dts"

/ {
compatible = "xlnx,zynq-picozed", "xlnx,zynq-7000";

aliases {
mmc0 = &sdhci0;
};
};

&sdhci0 {
u-boot,dm-pre-reloc;
status = "okay";
};

Do you think the is the best way?

If you can't use picozed without carrier board then zynq-picozed should
be dtsi.

Depends how zynq-picozed.dtsi will look but this line above can be
already there.

here
"xlnx,zynq-picozed-fmc-v2", "xlnx,zynq-picozed", "xlnx,zynq-7000";

with changes above it looks reasonable.

[U-Boot] [PATCH] ARM: zynq: Extend picozed board support

[Oscar Gomez Fuente]

Hi everyone,

In my opinion, use the picozed without a carrier board it doesn't make
 sense. You always are going to need a carrier board. Avnet has two models
the PicoZed FMC Carrier V2 and the PicoZed FMC Carrier V1. And the company
I'm working, it is going to desing a custom carrier board according to our
necessity.

So maybe, it's better to have only two .dts files. zynq-picozed-fmc-v2.dts
and zynq-picozed-fmc-v1.dts.

If we decide to have the zynq-picozed.dtsi and zynq-picozed-fmc-v2.dts,
we'll have to decide what hardware description is going to be in the
zynq-picozed-fmc-v2.dts and what hardware description is going to be
in zynq-picozed.dtsi.

for example the spi0 hw is in the picozed  board, but the SD (mmc0), eth0
(gem0) and serial0 (uart1) the HW is in the picoZed but the connectors are
in the PicoZed FMC Carrier V2, so It's a little bit confused if this HW
description has to be on the zynq-picozed.dtsi file or in the
zynq-picozed-fmc-v2.dts file. Do you know what I mean?

Please let me see you opinions about that.

Best regards.

I understand your concern. These SOMs are problematic and it is up2you
how you want to do it. My preference would be to add common stuff to
dtsi file and carried board stuff to dts file. If that configurations
have nothing in common then using just fmc dts is fine for me.
When ps7_init.* files are in place it should be visible how MIOs are
configured.

Thanks,
