Make the OF-compatible zImage per-board selectable. This allows the
image to only be built with the wrapper if the target actually uses it.
This fixes build-failures for the mpc85xx-p2020 subtarget.

Hardware
--------
CPU: Freescale P1020 2xe500 PPC
RAM: 256M DDR3 (Micron MT41J64M16JT-15E:G "D9MNJ")
NAND: 128M (Micron 2CA1)
BTN: 1x Reset
LED: Power - ETH - Radio1 - Radio2
UART: RJ-45 Cisco Pinout - 115200 8N1
Installation
------------
NOTE: You can find a repo with up-to-date instructions as well as
the required files here:
https://github.com/blocktrron/msm460-flashing
Required files
==============
You need a command-files as well as a U-Boot image.
The command-file has the following content (padded to 131072 bytes).
If you copy paste these, remove the newlines!
```
U-BOOT setenv ethaddr 02:03:04:05:06:07; setenv ipaddr 192.168.1.1;
setenv serverip 192.168.1.66; tftpboot 0x3000000 msm460-uboot.bin;
nand device; nand erase 0 0xC0000; nand write 0x3000000 0x0 0xC0000; reset
```
You can download the required U-Boot from this repository:
https://github.com/blocktrron/u-boot-msm/releases
Preparation
===========
Prepare a TFTP server serving two files:
- U-Boot NAND image as `msm460-uboot.bin`.
- OpenWrt factory image as `msm460-factory.bin`
- Command-file names `commands.tftp`
You can start a TFTP server in the current directory using dnsmasq:
```bash
sudo dnsmasq --no-daemon --listen-address=0.0.0.0 \
--port=0 --enable-tftp=enxd0 --tftp-root="$(pwd)" \
--user=root --group=root
```
Replace `enxd0` with the name of your network interface.
Procedure
=========
1. Assign yourself the IP-Address 192.168.1.66/24.
3. Connect the Router to the PC while keeping the reset button
pressed.
4. The LEDs will eventually begin to flash.
They will start to flash faster after around 15 seconds.
5. Release the reset button.
6. Start a new shell
7. Make sure you are currently in the directory where the tftp server
is located.
8. Run the following command:
```bash
tftp 192.168.1.1 -m binary -c put commands.tftp nflashd.cccc9999
```
You get the message "Transfer timed out."
To find out if you have been successful, please check the
blinking LED Pattern.

Add a universal zImage which can be loaded by mpc85xx boards at
load address 0x3000000. This allows boards to boot kernels larger than
16MB even if the image is loaded temporarily from NAND at offset
0x1000000 which some bootloaders do by default.

Convert the Enterasys WS-AP3710i access point to use the simpleImage
wrapper.
This is necessary, as the bootlaoder does not align the DTB correctly
(and does not support altering the FDT loadaddress). Booting images with
kernels 5.15 and later can break depending on the alignment on the DTB
within the FIT image.
