Subject: fat: Define MAX_CLUSTSIZE only if not defined in config
X-Git-Url: http://git.ipfire.org/gitweb.cgi?a=commitdiff_plain;h=2dd5b795d2a2d335555db68f6095c75d74a668fc;p=thirdparty%2Fu-boot.git

fat: Define MAX_CLUSTSIZE only if not defined in config

Define MAX_CLUSTSIZE only if not defined in board specific
config file as this size can be decreased to save memory
in some memory constrained cases.
