From: Michal Simek Date: Fri, 18 Jul 2025 11:24:08 +0000 (+0200) Subject: arm64: zynqmp: Add support for kd240 board X-Git-Tag: v6.18-rc1~147^2~29^2~5 X-Git-Url: http://git.ipfire.org/gitweb.cgi?a=commitdiff_plain;h=4f96c5db61f238e8a957df2b81d6343a5e38ca59;p=thirdparty%2Fkernel%2Flinux.git arm64: zynqmp: Add support for kd240 board The kit is using k24 SOM by default and it is used for motor control and DSP applications. K24 SOM is also possible to used with kv260 and kr260 CC which are also wired in Makefile.
