Subject: generic: lzma-loader: fix cache invalidation
X-Git-Tag: v19.07.0-rc1~10820
X-Git-Url: http://git.lede-project.org./?a=commitdiff_plain;h=8cd8698b6f06bf52fcbb1b7d41b2de27a0b0f938;p=openwrt%2Fstaging%2Fhauke.git

generic: lzma-loader: fix cache invalidation

The current code only partially invalidates both caches
because the cache size and cache-line size values are
incorrectly passed to the C code.

Fix the assembly code to pass the arguments in the correct
order.

Tested on RB532.
