From d085e692c98d0d7b57cc577ed9befda159cd4a40 Mon Sep 17 00:00:00 2001 From: Simon Glass Date: Wed, 13 Nov 2024 08:09:37 -0700 Subject: env: Provide a work-around for unquoting fdtfile Some boards use a CONFIG option to specify the value of this variable. This is normally handled by efi_get_distro_fdt_name() but in the case of sunxi this does not work, since 'soc' is sunxi, but the files are in the allwinner directory. Provide a work-around for this particular case.
