Subject: board_f: Drop return value from initdram()
X-Git-Url: http://git.dujemihanovic.xyz/?a=commitdiff_plain;h=088454cde245b4d431ce0181be8b3cbceea059d6;p=u-boot.git

board_f: Drop return value from initdram()

At present we cannot use this function as an init sequence call without a
wrapper, since it returns the RAM size. Adjust it to set the RAM size in
global_data instead, and return 0 on success.
