   zeroed as they should be. Now merged with normal .bss

 * Print more verbose CPU info for boards built on real silicon
 * Add support for SD-card detection on all ARC boards
 * Quite a few fixes for IoT DK

6 years agoARC: Don't use COMMON section for global not-initialized variables
Alexey Brodkin [Thu, 11 Oct 2018 20:12:05 +0000 (23:12 +0300)]
ARC: Don't use COMMON section for global not-initialized variables

By default GCC puts global non-initialized variables in COMMON section.
And we used to ignore existence of COMMON section in our linker
scripts though smart LD silently appended it right after .bss.

And the problem here is variables from COMMON section even though
require zeroing in run-time were not zeroed as they were placed
right after __bss_end symbol.

It was a pure luck we never faced serious problem due to this,
but now it is fixed.

Now as for some other architectures we'll just force GCC to put
those global variables in normal .bss section.

This solution is much nicer than adding COMMON section to each and
every linker script.

6 years agonet: Don't overwrite waiting packets with asynchronous replies
Joe Hershberger [Wed, 26 Sep 2018 21:49:02 +0000 (16:49 -0500)]
net: Don't overwrite waiting packets with asynchronous replies

Peter originally sent a fix, but it breaks a number of other things.
This addresses the original reported issue in a different way.

That report was:

> U-Boot has 1 common buffer to send Ethernet frames, pointed to by
> net_tx_packet.  When sending to an IP address without knowing the MAC
> address, U-Boot makes an ARP request (using the arp_tx_packet buffer)
> to find out the MAC address of the IP addressr. When a matching ARP
> reply is received, U-Boot continues sending the frame stored in the
> net_tx_packet buffer.
>
> However, in the mean time, if U-Boot needs to send out any network
> packets (e.g. replying ping packets or ARP requests for its own IP
> address etc.), it will use the net_tx_packet buffer to prepare the
> new packet. Thus this buffer is no longer the original packet meant
> to be transmitted after the ARP reply. The original packet will be
> lost.

This instead uses the ARP tx buffer to send async replies in the case
where we are actively waiting for an ARP reply.
