+         Make sure your ROM base does not include any file-header
+         information that is prepended to the kernel.
+
+         For example, the bootable U-Boot format (created with
+         mkimage) has a 64 byte header (0x40).  So while the image
+         you write to flash might start at say 0x20080000, you have
+         to add 0x40 to get the kernel's ROM base as it will come
+         after the header.

-         Say Y here if you want to plug devices into your computer while
-         the system is running, and be able to use them quickly.  In many
-         cases, the devices can likewise be unplugged at any time too.
-
-         One well known example of this is PCMCIA- or PC-cards, credit-card
-         size devices such as network cards, modems or hard drives which are
-         plugged into slots found on all modern laptop computers.  Another
-         example, used on modern desktops as well as laptops, is USB.
-
-         Enable HOTPLUG and build a modular kernel.  Get agent software
-         (from <http://linux-hotplug.sourceforge.net/>) and install it.
-         Then your kernel will automatically call out to a user mode "policy
-         agent" (/sbin/hotplug) to load modules and set up software needed
-         to use devices as you hotplug them.
