On master, the bootwrapper link-address for all simpleImage targets was
relocated to 0x15000000 due to growing kernel size.
This was not done on OpenWrt 23.05, as the decompressed kernel still
fits. However, with the wrapper for the WS-AP3710i, the bootloader
attempts execute in-place with the uImage load-address of 0x1000000. As
the image is compiled without the uImage header in mind, this naturally
fails.
In order to fix this, link the WS-AP3715i simpleImage at 0x15000000 as
done in master. This will force the bootloader to relocate the code to
the proper address and skip XIP.

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.
Compared with the patch applied to master, this compiles the loader at
the changed offset used in OpenWrt master. This is required, as U-Boot
loads the uImage at the offset the loader is currently compiled for.

UART: 115200 8N1 (RJ-45 Cisco)
Installation
------------
1. Grab the OpenWrt initramfs, rename it to ap3715.bin. Place it in
the root directory of a TFTP server and serve it at
192.168.1.66/24.
2. Connect to the serial port and boot the AP. Stop autoboot in U-Boot
by pressing Enter when prompted. Credentials are identical to the one
in the APs interface. By default it is admin / new2day.
3. Alter the bootcmd in U-Boot:
$ setenv ramboot_openwrt "setenv ipaddr 192.168.1.1;
setenv serverip 192.168.1.66; tftpboot 0x2000000 ap3715.bin; bootm"
$ setenv boot_openwrt "sf probe 0; sf read 0x2000000 0x140000 0x1000000;
bootm 0x2000000"
$ setenv bootcmd "run boot_openwrt"
$ saveenv
4. Boot the initramfs image
$ run ramboot_openwrt
5. Transfer the OpenWrt sysupgrade image to the AP using SCP. Install
using sysupgrade.
$ sysupgrade -n <path-to-sysupgrade.bin>
