This patch implements several updates: -disable CONFIG_ENV_OVERWRITE -add new hardware style variants and set the arch numbers appropriate -pass the serial# and hardware revision to the kernel -removed unused macros from include/configs/meesc.h -fixed multiline comment style

Signed-off-by: Daniel Gorsulowski Daniel.Gorsulowski@esd.eu --- v2: - don't write the ethernet address to the EMAC module anymore

v3: - removed function meesc_set_arch_number and moved code to checkboard() - reworked function get_board_serial() - removed unused macros from include/configs/meesc.h

v4: - fixed commit message (to many characters) - fixed indentation in switch-case statement - fixed multiline comment style

v5: - changed error message on invalid hw_type ("FATAL" to "ERROR")
