[OpenWrt] Flash 由4M改…

http://www.right.com.cn/forum/thread-75309-1-1.html

trunk/tools/firmware-utils/src/mktplinkfw.c 只修改fw_max_len为0xfc0000，16M flash .id = "4M", .fw_max_len = 0xfc0000, .kernel_la = 0x80060000, .kernel_ep = 0x80060000, .rootfs_ofs = 0x140000, 新版只用改fw的大小，分区表会自动认，不用像老版自己定义每个分区大小了。

Part Three: Compile your openwrt firmware:

1. Checkout trunk and update feeds as other common
tutorials

2. Modify Openwrt code to support and partition your flash:

/trunk/tools/firmware-utils/src/mktplinkfw.c

fw_max_len = 0x7c0000

3. menuconfig and make your image as common tutorials. save the
image openwrt-ar71xx-generic-tl-mr3420-v1-squashfs-factory.bin for
future usage.

4. back up your 64k art (wirelss driver data, without it your
wireless does not work.) this is important! you can also use the
backup one from other tp-link ar7241 chipset routers.
