This patchset was originally from NIIBE Yutaka.

These patch update the m32r kernel for a new bootloader "m32r-g00ff".  The
"m32r-g00ff" has been written and developed by NIIBE Yutaka, and released
under the GPL from http://www.gniibe.org/.

So far, it supports two types of booting operations,
CF boot and Network boot (HTTP boot).

 * CF boot - boot from CompactFlash or Microdrive(TM)
   We can boot a kernel from CF device.
   To make use of m32r-g00ff, we just put a first stage IPL(initial program
   loader) into a flash memory, and a secondary bootloader into CF media device.
   Currently, LILO-21.4.4 can be used to write m32r-g00ff into the boot sector
   of CF device on a cross development environment.

 * HTTP boot - boot via network with HTTP protocol
   By using m32r-g00ff, we can download and boot a kernel image from 
   a web-server.  The m32r-g00ff downloads a kernel image from a given URL,
   resolving the webserver's IP address by DNS.
   As a preparation, we just place a secondary bootloader binary and
   a kernel image on the webserver.

- Position-independent zImage support;
  this aims at removing constraints of zImage(vmlinuz)'s location.
