[PATCH] ARM: dts: Fix booting on Rinato market device

[PATCH] ARM: dts: Fix booting on Rinato market device

[Krzysztof Kozlowski]

The bootloader on market Rinato (Gear 2) device checks for revision in
compatible field of DTB. If it is not present or lower than required
then booting fails with: "Could not do normal boot. (no DTB found)".

Log of bootloader in case of failure:
h/w: revision  = 0x06
h/w: schematic = SM-R380_Rev0.5_Final_0205
date = 2000/01/01 12:00:21 (UTC)

 No need to update kernel type.

Could not do normal boot. (no DTB found)

Add a "rev06" suffix to compatible to satisfy the bootloader.

I think it is wrong. The released bootloader from Samsung is not u-boot.
Instead, you have to update u-boot to support Exynos3250-basd Rinato board.

The bootloader on device also was not a u-boot. So the fix is for native
bootloader delivered on device.

I do not insist that this is proper fix. It was just needed to boot the
device with custom kernel.

Anyway, thanks for comments!

Best regards,
Krzysztof

Hi Krzysztof and Chanwoo,

So, we don’t need this to fix the problem Krzysztof said? OK.

Yes.
The released bootloader from Samsung is not general and not opened.
We have to support Exynos3250-based Rinato on general bootloader.
