From 13634bb6585ec0e789da7504146873fb492456e5 Mon Sep 17 00:00:00 2001 From: Alper Nebi Yasak Date: Wed, 28 Oct 2020 00:15:11 +0300 Subject: rockchip: gru: Allow setting up clocks in U-Boot proper Commit fe974716326c ("rockchip: rk3288: Allow setting up clocks in U-Boot proper") fixes some clock issues when chainloading U-Boot on rk3288 chromebooks. Part of that change is still available in veyron's board_early_init_r() function. Since chain-loading U-Boot proper from vendor firmware is possible on gru boards as well, do the same thing for them too. On rk3399, this needs to detect whether SPL was run via handoff, so enable that and bloblist kconfigs it needs for chromebook_bob.
