Subject: ramips: remove ralink_default_fw_size_xxx variables
X-Git-Url: http://git.lede-project.org./?a=commitdiff_plain;h=9d87a58d347a299a8d3c27b038d5bb8a7d8d5b89;p=openwrt%2Fstaging%2Fluka.git

ramips: remove ralink_default_fw_size_xxx variables

There are frequent examples of the ralink_default_fw_size_xxx
variables being used to "roughly" set flash size without caring
about the actual size of the firmware partition.

To discourage this behavior, this patch removes the variables and
just sets IMAGE_SIZE by its numeric value for each target.
