Subject: [U-Boot] [PATCH v5 20/27] ARM: tegra: Enable position independent build for 64-bit
Date: Mon, 15 Apr 2019 11:32:32 +0200	[thread overview]
Message-ID: <20190415093239.27509-21-thierry.reding@gmail.com> (raw)
In-Reply-To: <20190415093239.27509-1-thierry.reding@gmail.com>

From: Thierry Reding <treding@nvidia.com>

Note that U-Boot is always chainloaded from cboot starting with L4T
release 28. cboot always loads U-Boot to a fixed address, so making
the builds position independent isn't strictly necessary. However,
position independent builds can be convenient because if U-Boot is
ever loaded to an address different from its link address, it will
still be able to boot.
