[U-Boot] [PATCH v4 03/13] arm: Export and promote relocation symbols

Simon Glass sjg at chromium.org
Tue Feb 21 02:32:45 CET 2012 

These symbols are currently part-way through each file. Most have the same
code, but there are small variations.

We move all these relocation symbols to the start next to the other
exported symbols, and export them so we can use them in generic relocation
code.

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

Changes in v4:
- Split out change to move relocation symbols to top of start.S files
