Subject: [RFC PATCH 3/4] jumparch64: insert into bootm
Date: Mon, 10 Aug 2020 16:26:51 +0200	[thread overview]
Message-ID: <20200810142652.40669-4-linux@fw-web.de> (raw)
In-Reply-To: <20200810142652.40669-1-linux@fw-web.de>

From: Frank Wunderlich <frank-w@public-files.de>

if uboot is 32bit and linux-kernel is 64bit packed into armhf mkimage
(like official kernels for bpi-r64) call jumparch64 to switch to 64bit
mode after unpacking the kernel-image
