Debug in Qemu

Now it is time to try the debug in qemu.

1. Start the qemu use the switch "-s"
$ qemu-system-arm -s -kernel uImage --nographic -serial stdio -M mini2440

2. Run the gdb with the uboot, and then connect to the port 1234
$ arm-none-linux-gnueabi-gdb ~/mini2440/bootldr/mini2440/u-boot
(gdb) target remote localhost:1234

all right, you can debug the uboot now ^_^
