From: Konstantin Porotchkin Date: Thu, 16 Feb 2017 11:52:32 +0000 (+0200) Subject: arm64: a37xx: Disable DB configurations on ESPRESSOBin board X-Git-Tag: v2017.05-rc1~17^2~6 X-Git-Url: https://git.sur5r.net/?a=commitdiff_plain;h=9566268fd8e2faf7d7979358a369e73962a99654;p=u-boot arm64: a37xx: Disable DB configurations on ESPRESSOBin board Bypass XHCI and AHCi board configuration flow on ESPRESSOBin community board. The community board does not have i2c expander and USB VBUS is always on, so the scan for AHCi and USB devices can be faster without unneded configurations.
