[U-Boot] [PATCH-V4] at91: Update meesc board to new SoC access
Daniel Gorsulowski
Daniel.Gorsulowski at esd.eu
Tue Jul 27 09:23:52 CEST 2010
* convert meesc board to use c stucture SoC access
* change gpio access to at91_gpio syntax
* moved CONFIG_SYS_HZ below board and cpu defines (purely cosmetic)
Signed-off-by: Daniel Gorsulowski <Daniel.Gorsulowski at esd.eu>
---
v2: fixed copyright changing error according to Wolfgangs hint
v3: removed some whitespace, indentation and coding style errors
v4: fixed build error (removed jamming parenthesis in pio defines)
