Subject: fastboot: Rename fb_set_reboot_flag to fastboot_set_reboot_flag
X-Git-Tag: v2018.07-rc1~15^2~10
X-Git-Url: https://git.librecmc.org/?a=commitdiff_plain;h=8a65bd63720b813d8082a2c14bdde5ade4673d87;p=oweals%2Fu-boot.git

fastboot: Rename fb_set_reboot_flag to fastboot_set_reboot_flag

Rename fb_set_reboot_flag to fastboot_set_reboot_flag so it matches
all other fastboot code in the global name space. Fix the guards around
them so that they're dependent on FASTBOOT, not just USB_FUNCTION_FASTBOOT.

Move the weak implementation of fastboot_set_reboot_flag to fb_common.c
so we can call it from non-USB fastboot code.
