can't interrupt when printing T T T T T

[duhuanpeng <iu87m888m@qq.com>]

Hello, I boot my barebox by barebox from tftpserver. I poweroff my
switcher. and barebox began to print
- - - -
Booting entry 'net'
T T T T T T T T T T T T T T T T T T T T T T T T T T T T T T T T T T T T T T T T IP 192.168.1.88 is not reachable
- - - -
I try to hit ctrl-c and some other keys. but I can't stop it printing 'T'.
so I added some piece of code to test it

fs/tftp.c
   static int tftp_poll(struct file_priv *priv)
 {
+
+       if(tstc()) {
+               printf("%s", __func__);
+               putchar(getchar());
+       }
+
        if (ctrlc()) {

net/net.c
 
 void net_poll(void)
 {
+       if(tstc()) {
+               printf("%s", __func__);
+               putchar(getchar());
+       }
+


net/eth.c

static int __eth_rx(struct eth_device *edev)
{
	int ret;

+       if(tstc()) {
+               putchar(getchar());
+               printf("|-_-|");
+       }
+
- - - - - - - -
the result:

I found it the routine (tftp_poll) didn't catch the key input.
mostly the input is catched by net_poll().
could anyone help to move the ctrlc() dection into the right place?
