From: Aleksander Jan Bajkowski Date: Mon, 27 Jan 2025 20:23:50 +0000 (+0100) Subject: mediatek: filogic: increase spi flash memory speed on ZyXEL EX5601 X-Git-Url: http://git.ipfire.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=refs%2Fpull%2F18694%2Fhead;p=thirdparty%2Fopenwrt.git mediatek: filogic: increase spi flash memory speed on ZyXEL EX5601 Reduces boot time by 3s on a freshly installed image. This device has a large flash and the gain can be higher with more packages installed. According to the datasheet, this is the maximum frequency supported by the Micron and Macronix chips that are installed in these devices. Tested on three units over a two month period.
