From d73d9fb7e2384b55a6c1866a5d914a621cf8563a Mon Sep 17 00:00:00 2001 From: Eugeniu Rosca Date: Tue, 9 Apr 2019 21:11:40 +0200 Subject: [PATCH] fastboot: add support for 'getvar platform' Our R-Car3 Android userspace relies on the output of 'fastboot getvar platform' and U-Boot currently is not able to handle it: host $> fastboot getvar platform getvar:platform FAILED (remote: Variable not implemented) finished. total time: 0.001s We either have the option of adding 'fastboot.platform' variable to the default/saved environment as a workaround or add proper 'fastboot getvar platform' support in U-Boot via this patch. In the latter case, other platforms can benefit from it too. Note that R-Car3 already exports 'platform' environment variable via v2019.01 commit 00e4b57e9e71c3 ("ARM: rmobile: Set environment variable containing CPU type").
