efi_loader: remove EFI_UNICODE_COLLATION_PROTOCOL

In EFI 1.10 a version of the Unicode collation protocol using ISO 639-2
language codes existed. This protocol is not part of the UEFI specification
any longer. It was however required to run the UEFI Self Certification Test
(SCT) II, version 2.6, 2017. So we implemented it for the sole purpose of
running the SCT.

As the SCT does not need the protocol anymore it is time for removal.

net: Do not respond to ICMP_ECHO_REQUEST if we do not have an IP address

While doing DHCP the interface IP is set to 0.0.0.0. This causes the
check in net.c on dst_ip to be effectively skipped, and all IP datagrams
are accepted up the IP stack. In the case of an ICMP_ECHO_REQUEST for the

an ICMP_ECHO_REPLY is sent. The source address of the ICMP_ECHO_REPLY is
0.0.0.0, which is an illegal source address.

This can happen in common practice with the following sequence:
DHCP (U-Boot or OS) acquires IP address 10.0.0.1
System reboots
U-Boot starts DHCP and send DHCP DISCOVER
DHCP server decides to OFFER 10.0.0.1 again
  (perhaps because of existing lease or manual configuration)
DHCP server tries to PING 10.0.0.1 to see if anyone is squatting on it
DHCP server still has our MAC address in its ARP table for 10.0.0.1
U-Boot receives PING, and responds with an illegal source address
This may further result in a the DHCP server seeing the response as
  confirmation that someone is squatting on 10.0.0.1, and picking a
  new IP address from the pool to try again

net: eth-uclass: avoid running start() twice without stop()

Running the start() handler twice without a stop() inbetween completely
breaks communication for some ethernet drivers like fec_mxc.

eth_halt() is called before each eth_init(). Due to the switch to
eth_is_active() in commit 68acb51f442f ("net: Only call halt on a driver
that has been init'ed"), this is not sufficient anymore when netconsole
is active: eth_init_state_only()/eth_halt_state_only() manipulate the
state check that is performed by eth_is_active() without actually
calling into the driver.

The issue can be triggered by starting a network operation (e.g. ping or
tftp) while netconsole is active.

Add an additional "running" flag that reflects the actual state of the
driver and use it to ensure that eth_halt() actually stops the device as
it is supposed to.

So with the current implementation pin functionality could be overwritten
silently, for example if the same pin is added for SPI and serial.

overwritten. Also a warning message is printed if the current pin is being

This also avoids pin re-muxing to same type that is for example from
command line device is asked to re-probe/select (mmc dev x) we return
early with success in this case as the pin is already muxed.
