[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;
        };

+
+       ethernet_phy: ethernet-phy at 0 {
+               reg = <0>;
+       };
+};

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

/dts-v1/;
#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?


Best regards.
