+ 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.
