[PATCH] ath79: switch to kernel loader for ar9344 CPE/WBS
Sander Vanheule

Sun Sep 27 09:59:33 EDT 2020
Now that firmware partitions starting with an ELF kernel loader can be
split automatically, move the TP-Link ar9344-based CPE and WBS devices
from an OKLI loader to a plain kernel loader.
This reduces the size of the device images a bit (2kB for initramfs and
sysupgrade). More importantly it takes away the requirement to
periodically resize the kernel partition to allow for larger kernels.
Note that the firmware size in tplink-safeloader.c is one erase block
smaller than the one in the DTSI, due to some runtime space reclamation
happening on these devices.
Also rebases tplink-eap2x5 on the new tplink-safeloader-elf base device.

I've build tested this patch for all affected devices, but I cannot test
these new images on the CPE/WBS devices as I do not have these. Any
volunteer willing to test this patch on their device would be welcome to
do so.
