[PATCH 5.4 15/33] ARM: use LOADADDR() to get load address of sections

[Greg Kroah-Hartman]

From: "Russell King (Oracle)" <rmk+kernel@xxxxxxxxxxxxxxx>

commit 8d9d651ff2270a632e9dc497b142db31e8911315 upstream.

Use the linker's LOADADDR() macro to get the load address of the
sections, and provide a macro to set the start and end symbols.
