with 6.1, the kernel no longer fitted into the 16 MiB and
kicking down the can and increasing KERNEL_SIZE to 20 MiB
didn't help as the device failed to boot.
Using 'kernel-bin | gzip | uimage gzip' didn't work since the
uboot does not have enough heap to decompress these big kernels.
And finally playing around with uboot was more a hassle than
converting this device to take the simpleImage-boot-route in
the future.
Note: The device now takes even longer on the first boot-up after
the flash due to JFFS2 initializing all the remaining flash.
Be prepared to wait up to 10 minutes before the green status LED
stops blinking and will shine a solid green!
(On the plus site: the device now has ~10 MiB of additional
space for rootfs+rootfs_data).
Note2: This patch includes a kernel patch refresh.

Hardware
--------
SoC: NXP P1010 (1x e500 @ 800MHz)
RAM: 256M DDR3 (2x Samsung K4B1G1646G-BCH9)
FLASH: 32M NOR (Spansion S25FL256S)
BTN: 1x Reset
WiFi: 1x Atheros AR9590 2.4 bgn 3x3
2x Atheros AR9590 5.0 an 3x3
ETH: 2x Gigabit Ethernet (Atheros AR8033 / AR8035)
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>
