From f86bd769fd0624106ecd2c5d500518e8b83a4e27 Mon Sep 17 00:00:00 2001 From: Thomas RIENOESSL Date: Thu, 29 Nov 2018 20:07:12 -0800 Subject: [PATCH] coreboot: only init usb if necessary Up until now the call to initialize the USB subsystem was hardcoded for U-Boot running as a coreboot payload. This was used to enable the use of a USB keyboard in the U-Boot shell. However not all boards might need this functionality. As initializing the USB subsystem can take a considerable amount of time (several seconds on some boards), we now initialize the USB subsystem only if U-Boot is configured to use USB keyboards.
