INAGAKI Hiroshi f7f9e6bd20 ramips: use parser_trx for Buffalo WCR-1166DS ... Buffalo WCR-1166DS uses trx-fomatted firmware and the custom magic number (0x5C436F74, "\Cot") is required for OpenWrt installation from OEM WebUI. But the current mtdsplit_trx doesn't support the custom magic number and fail to parse and split to kernel and rootfs when the factory image is flashed. Then, the kernel fails to mount rootfs automatically and panics. Before the commit fddc78bc11, mtdsplit_trx was patched in ramips target and the device-specific magic number was supported only for WCR-1166DS[1]. But the patch was not inherited to the later version of the kernel and deleted by the above commit, then, the custom magic number support was broken.
