We already have too many places in the Linux kernel and its decompressor that try to work out whether a device tree or ATAGs are present and how large, and that is done in assembly code. We don't need more complexity to deal with some kind of wrapping of device trees as well. -- RMK's Patch system: http://www.armlinux.org.uk/developer/patches/ FTTC broadband for 0.8mile line in suburbia: sync at 8.8Mbps down 630kbps up According to speedtest.net: 8.21Mbps down 510kbps up From mboxrd@z Thu Jan 1 00:00:00 1970 From: linux@armlinux.org.uk (Russell King - ARM Linux) Date: Tue, 29 May 2018 23:51:14 +0100 Subject: [RFC 12/13] ARM: dts: ti: add dra71-evm FIT description file In-Reply-To: References: <1523956215-28154-1-git-send-email-t-kristo@ti.com> <1523956215-28154-13-git-send-email-t-kristo@ti.com> <20180417092924.GB20335@flint.armlinux.org.uk> <20180417144913.GD5669@atomide.com> <43ff3894-a287-1558-687c-40f50712735c@ti.com> <20180522200100.GA23937@rob-hp-laptop> <16a6017f-96c8-42d8-38bc-5cdd36d6793f@gmail.com> <20180529173314.GN17671@n2100.armlinux.org.uk> Message-ID: <20180529225114.GO17671@n2100.armlinux.org.uk> To: linux-arm-kernel@lists.infradead.org List-Id: linux-arm-kernel.lists.infradead.org On Tue, May 29, 2018 at 03:45:12PM -0700, Frank Rowand wrote: > If the kernel applies the overlay, an alternative to drivers is that the > kernel could receive the overlay(s) in a similar manner as the method it > currently receives the base devicetree.
