From b00ced38e3172823c0a554004585a683dfd95041 Mon Sep 17 00:00:00 2001 From: Linus Walleij Date: Tue, 27 Jul 2021 15:00:39 +0200 Subject: [PATCH] ARM: ixp4xx: Delete Avila boardfiles This board is replaced with the corresponding device tree. There is also the "loft" board which is just a Kconfi entry and which reuses the same boardfile. If there is interest in the Loft variant and someone is willing to test I can create a special DT superset for this board, which only differs in PCI set-up.
