Simon Glass e895a4b06f fdt: Allow ft_board_setup() to report failure 
This function can fail if the device tree runs out of space. Rather than
silently booting with an incomplete device tree, allow the failure to be
detected.

Unfortunately this involves changing a lot of places in the code. I have
not changed behvaiour to return an error where one is not currently
returned, to avoid unexpected breakage.

Eventually it would be nice to allow boards to register functions to be
called to update the device tree. This would avoid all the many functions
to do this. However it's not clear yet if this should be done using driver
model or with a linker list. This work is left for later.

Freescale MPC8610HPCD board
===========================


Building U-Boot
---------------

    $ make MPC8610HPCD_config
    Configuring for MPC8610HPCD board...

    $ make


Flashing U-Boot
---------------
The flash is 128M starting at 0xF800_0000.

The alternate image is at 0xFBF0_0000
The      boot image is at 0xFFF0_0000.


To Flash U-Boot into the booting bank:

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


To Flash U-boot into the alternate bank

	tftp 1000000 u-boot.bin
	erase fbf00000 +$filesize
	cp.b 1000000 fbf00000 $filesize


pixis_reset command
-------------------
A new command, "pixis_reset", is introduced to reset mpc8610hpcd 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


DIP Switch Settings
-------------------
To manually switch the flash banks using the DIP switch
settings, toggle both SW6:1 and SW6:2.
