3. Flash U-Boot
---------------
The flash range 0xFF800000 to 0xFFFFFFFF can be divided into 2 halves.
It is possible to use either half to boot using u-boot.  Switch 5 bit 2
is used for this purpose.

0xFF800000 to 0xFFBFFFFF - 4MB
0xFFC00000 to 0xFFFFFFFF - 4MB
When this bit is 0, U-Boot is at 0xFFF00000.
When this bit is 1, U-Boot is at 0xFFB00000.

Use the above mentioned flash commands to program the other half, and
use switch 5, bit 2 to alternate between the halves.  Note: The booting
version of U-Boot will always be at 0xFFF00000.

To Flash U-Boot into the booting bank (0xFFC00000 - 0xFFFFFFFF):

	tftp 1000000 u-boot.bin
	protect off all
	erase fff00000 +$filesize
	cp.b 1000000 fff00000 $filesize

or use tftpflash command:
	run tftpflash

To Flash U-boot into the alternative bank (0xFF800000 - 0xFFBFFFFF):

	tftp 1000000 u-boot.bin
	erase ffb00000 +$filesize
	cp.b 1000000 ffb00000 $filesize

5. pixis_reset command
--------------------
A new command, "pixis_reset", is introduced to reset mpc8641hpcn board
using the FPGA sequencer.  When the board restarts, it has the option
of using either the current or alternate flash bank as the boot
image, with or without the watchdog timer enabled, and finally with
or without frequency changes.

Usage is;

	pixis_reset
	pixis_reset altbank
	pixis_reset altbank wd
	pixis_reset altbank cf <SYSCLK freq> <COREPLL ratio> <MPXPLL ratio>
	pixis_reset cf <SYSCLK freq> <COREPLL ratio> <MPXPLL ratio>

Examples;

	/* reset to current bank, like "reset" command */
	pixis_reset

	/* reset board but use the to alternate flash bank */
	pixis_reset altbank

	/* reset board, use alternate flash bank with watchdog timer enabled*/
	pixis_reset altbank wd

	/* reset board to alternate bank with frequency changed.
	 * 40 is SYSCLK, 2.5 is COREPLL ratio, 10 is MPXPLL ratio
	 */
	pixis-reset altbank cf 40 2.5 10

Valid clock choices are in the 8641 Reference Manuals.
