Subject: [U-Boot] [PATCH v3 15/19] ARM: tegra: Enable position independent build for 64-bit
Date: Thu, 21 Mar 2019 19:01:14 +0100 [thread overview]
Message-ID: <20190321180118.26475-16-thierry.reding@gmail.com> (raw)
In-Reply-To: <20190321180118.26475-1-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.
