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
matching MAC address (regardless of destination IP), the result is that
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

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 68acb51f44 ("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.

By default on startup all the pin types are configured to
PINMUX_TYPE_NONE (in sh_pfc_map_pins()), when pin is set as GPIO the
pin type is updated to PINMUX_TYPE_GPIO. But the type is not updated
when the pin is set as a function in sh_pfc_pinctrl_pin_set() or
sh_pfc_pinctrl_group_set() calls (these calls only set the MUX if
the pin type is PINMUX_TYPE_NONE ie unused).
So with the current implementation pin functionality could be overwritten
silently, for example if the same pin is added for SPI and serial.
This patch makes sure of updating pin type after every successful call to
sh_pfc_config_mux() and thus fixing from pin functionality to be
overwritten. Also a warning message is printed if the current pin is being
overwritten before abort.
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.
