Subject: [PATCH gatesgarth] arm-autonomy/u-boot: Modified kernel_addr for fvp-base with xen
Date: Wed, 24 Mar 2021 15:26:39 +0000	[thread overview]
Message-ID: <20210324152639.4375-1-nathan.dunne@arm.com> (raw)

From: Nathan Dunne <Nathan.Dunne@arm.com>

Modified the default booti command for fvp-base with xen to boot
into xen at 0x84000000, rather than requiring the user to break
into the u-boot prompt.
