500 kexec is a system call that implements the ability to shutdown your

503 you can start any kernel with it, not just Linux.

508 is properly shutdown, so do not be surprised if this code does not
509 initially work for you. It may help to enable device hotplugging

666 Compact Flash is a small, removable mass storage device introduced
667 in 1994 originally as a PCMCIA device. If you say `Y' here, you
668 compile in support for Compact Flash devices directly connected to
669 a SuperH processor. A Compact Flash FAQ is available at
670 <http://www.compactflash.org/faqs/faq.htm>.

672 If your board has "Directly Connected" CompactFlash at area 5 or 6,
673 you may want to enable this option. Then, you can use CF as
674 primary IDE drive (only tested for SanDisk).

686 If your board has "Directly Connected" CompactFlash, You should
687 select the area where your CF is connected to.

689 - "Area5" if CompactFlash is connected to Area 5 (0x14000000)
690 - "Area6" if it is connected to Area 6 (0x18000000)
