+ * This emulation includes the following:
+ *
+ * 1. Emulation of the keyboard, by converting keypresses received from SDL

+ * key layout is read from the device tree.
+ *
+ * 2. Emulation of vboot context - so this can be read/written as required.
+ *
+ * 3. Save/restore of EC state, so that the vboot context, flash memory
+ * contents and current image can be preserved across boots. This is important
+ * since the EC is supposed to continue running even if the AP resets.
+ *
+ * 4. Some event support, in particular allowing Escape to be pressed on boot
+ * to enter recovery mode. The EC passes this to U-Boot through the normal
+ * event message.
+ *
+ * 5. Flash read/write/erase support, so that software sync works. The
+ * protect messages are supported but no protection is implemented.
+ *
+ * 6. Hashing of the EC image, again to support software sync.
+ *
+ * Other features can be added, although a better path is probably to link
