+Generic reboot mode core map driver
+
+This driver get reboot mode arguments and call the write
+interface to stores the magic value in special register
+or ram . Then the bootloader can read it and take different
+action according to the argument stored.
+
+Required properties:
+- compatible: only support "syscon-reboot-mode" now.
+
+Each mode is represented as a sub-node of reboot_mode:
+
+Subnode required properties:
+- linux,mode: reboot mode command,such as "loader", "recovery", "fastboot".
+- loader,magic: magic number for the mode, this is vendor specific.
+
+Example:
+ reboot_mode {
+ compatible = "syscon-reboot-mode";
+ offset = <0x40>;
+
+ loader {
+ linux,mode = "loader";
+ loader,magic = <BOOT_LOADER>;
+ };
+
+ maskrom {
+ linux,mode = "maskrom";
+ loader,magic = <BOOT_MASKROM>;
+ };
+
+ recovery {
+ linux,mode = "recovery";
+ loader,magic = <BOOT_RECOVERY>;
+ };
+
+ fastboot {
+ linux,mode = "fastboot";
+ loader,magic = <BOOT_FASTBOOT>;
+ };
+ };
So one minor thought here. While the commands are somewhat vendor
specific, would it be a good idea for the example commands to match
the common commands on Android devices? For example, usually
"bootloader" is what gets you into fastboot mode on nexus devices.

When I run the "adb help" , I got the following message:
adb reboot [bootloader|recovery] - reboots the device, optionally
into the bootloader or recovery program
adb reboot-bootloader - reboots the device into the bootloader
It only says "adb reboot-bootloader" will reboot the device into
bootloader, not specific to fastboot.
I add @Simon from Google here, maybe he can give some suggestions.
