Subject: [U-Boot,v5,21/23] x86: Use sections header to obtain link symbols
Date: Fri, 08 Feb 2013 05:12:17 -0000
From: Simon Glass <sjg@chromium.org>
X-Patchwork-Id: 219189
Message-Id: <1360336339-10703-22-git-send-email-sjg@chromium.org>
To: U-Boot Mailing List <u-boot@lists.denx.de>
Cc: Graeme Russ <graeme.russ@gmail.com>, Tom Rini <trini@ti.com>,
 Vadim Bendebury <vbendeb@chromium.org>

These are defined in asm-generic/sections.h, so remove them from
architecture-specific files.

Signed-off-by: Simon Glass <sjg@chromium.org>

---
Changes in v5:
- Include asm/sections.h in x86 sdram code
- Define _end instead of __end for x86

Changes in v4:
- Use asm/sections.h instead of asm-generic/sections.h

Changes in v3:
- Add header to new x86 relocate.c and init_helpers.c

Changes in v2: None
