From ecd8557937a896dd1049f67806482bfb6edf140b Mon Sep 17 00:00:00 2001 From: Dileep Katta Date: Fri, 27 Mar 2015 23:06:57 +0530 Subject: fastboot: ARM: OMAP5: Enable reboot-bootloader Implemented fb_set_reboot_flag() for OMAP5 to set an environment variable 'dofastboot' when reboot-bootloader called. This environment variable will be checked in boot command and fastboot will be called if the variable is set. If the bootcmd env variable of OMAP5 common is overwritten with board-specific command, then these changes will not apply. This was originally intended for DRA7 platform, but now applies to all OMAP5.
