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. Signed-off-by: Linus Walleij <linus.walleij@linaro.org>
