I think next step is to add the flash support on my board,
below is my spi nor flash parameters, how can I make it work with squashfs filesystem ?
Model : N25Q256A
SIZE: totoally 32MB, (64KB sector size)
bus num : 0
gpio cs num : 0
internal interface with CPU
the bcm4708.dtsi and bcm5301x.dtsi did not show much information about spi-nor-flash.

There is a breakthrough, the xxx.trx file is not ok while the zImage-xxx.lzma can work.
But still remains lots of work to be done.
the target platform *.dts file should be like this:
/dts-v1/;
#include "bcm4708.dtsi"
/ {
compatible = "via,vnt5903", "brcm,bcm4708";
model = "VIA Networking Technology 5903 (BCM4708)";
chosen {
bootargs = "console=ttyS0,115200 earlyprintk";
};
memory {
reg = <0x00000000 0x08000000
0x88000000 0x08000000>; /* 128MB + 128MB = 256MB */
};
chipcommonA {
uart0: serial at 0300 {
status = "okay";
};
uart1: serial at 0400 {
status = "okay";
};
};
};
below information is the log from zImage.xxxx.lzma:

but the "XZ-compressed data is corrupt" is the message of openwrt-trunk kernel that under linux-3.14.xx/lib/compress_unxz.c +371
