The DIR-890L is very similar to DIR-885L, but has both USB2
and USB3. The signature for the wrgac36 board was copied from
DD-Wrt.
The DIR-890L bootstrap will only load the first 2 MB after
the SEAMA header in the NAND flash, uncompress it with LZMA
and execute it. Since the compressed kernel will not fit in
2 MB we have a problem. Solve this by putting a LZMA
compressed U-Boot into the first 128 KB of the flash
followed by the kernel. The bootstrap will then uncompress
and execute U-Boot and then we let U-Boot read the kernel
from flash and execute it.

I see this patch is applied. $(STAGING_DIR_IMAGE)/$(DEVICE_NAME)-u-boot.bin
won't be created unless PACKAGE_u-boot-dir-890l is enabled. For some
reason, regardless of which device is selected on menuconfig, the OpenWrt
SDK will compile an image for every device on the target. So if any device
other than D-Link DIR-890L is selected on menuconfig,
PACKAGE_u-boot-dir-890l won't be enabled. Therefore, the compilation
process will fail while preparing an image for DIR-890L.
