Subject: N900 v3.19-rc5 arm atags_to_fdt.c is broken
Date: Fri, 23 Jan 2015 22:39:55 +0100	[thread overview]
Message-ID: <201501232239.55801@pali> (raw)

[-- Attachment #1: Type: Text/Plain, Size: 534 bytes --]

Hello,

when I boot zImage with appended DT n900 in qemu fdt_open_into() 
function called from file arch/arm/boot/compressed/atags_to_fdt.c 
(in function atags_to_fdt) always returns -FDT_ERR_NOSPACE.

It means that all ATAGS (including cmdline arguments) passed by 
bootloader are ignored.

On real n900 device I see that booted DT version also ignore 
cmdline arguments from bootloader. I cannot debug decompress code 
on real device, but I think it is same problem as in qemu.
