Subject: CHIPPro NAND issue with 4.12 rc1
Hi All,
I'm trying to boot a CHIPPro with the stock 4.12 rc1 kernel. If I make
no modifications to the sun5i-gr8-chip-pro.dtb the kernel boots but
can't find the root partition.
So I added the partitions to the dts file
diff --git a/arch/arm/boot/dts/sun5i-gr8-chip-pro.dts
b/arch/arm/boot/dts/sun5i-gr8-chip-pro.dts
index c55b11a..0e61e6b 100644
--- a/arch/arm/boot/dts/sun5i-gr8-chip-pro.dts

+ label = "rootfs";
+ reg = /bits/ 64 <0x1000000 0x1f000000>;
+ };
};
};
and now the kernel finds the partition but it times out trying to mount
it. It seems to be something in the dts files because if I use the
ntc-gr8-crumb.dts from the ntc 4.4.30 kernel then the system boots all
the way to userland.
