Re: [Ltib] Multiple .dts files

[Stuart Hughes]

Hi Mariano,

The .dts file in arch/powerpc/boot/dts/ is part of kernel sources, these 
are separately maintained to the LTIB config/platform/*/ files.

From what I can see, the BSP developer has created a number of .dts 
files to work for a number of different hardware boot scenarios.  When 
LTIB builds the kernel it does:

    for DTC_NAME in $DTC_NAMES
    do
       _create_dtb_file....
    done

This means they end up with one kernel that can be booted using 
different .dtb files to cope with variations of hardware.  I suspect one 
of those is the same as the one described by the kernel-sources default 
.dts file.

Regards, Stuart
