1. Could we use tftp sever in u-boot ?

2. How to enable tftp server or tftp client ? Such as# define in <include>/<configs>/<board>.h, as we hasn&#39;t finish the net device(dm9000a) driver. We are still studying the source tree of u-boot and <u-boot>/readme.

3. Maybe there are two ways to boot linux:

(1) like smcnutt: use mkimage to compress the linux; tftp client down at proper SDRAM&#39;s address; bootm;

(2) tftp down the vmlinux.bin to 0x0 of SDRAM, "jump 0x0"

Let&#39;s verify them by ourselves, too.

Thank you in advance.
