[U-Boot] [PATCH-V3] at91: Update meesc board to new SoC access
* 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@esd.eu ---
v2: fixed copyright changing error according to Wolfgangs hint v3: removed some whitespace, indentation and coding style errors
