Some DHCP servers (notably dnsmasq) always transmit DHCP Option 28,
Broadcast Address as specified in RFC 2132. Without this patch u-boot
displays the warning:
*** Unhandled DHCP Option in OFFER/ACK: 28
The patch suppresses the warning and ignores DHCP Option 28. There is
no environment variable to set the broadcast address into and if for
some reason u-boot needs the broadcast it can be calculated from
ipaddr and netmask.
Now DT support is becoming common for all new SoC's. Hence it is better
to have option for getting specific FDT from the remote server.
This patch adds support for new label i.e. 'fdt'. This will allow to
retrieve 'fdt blob' from the remote server. This patch take care for
the following scenarios.
The usage of fdt is optional.
The 'fdt blob' can be retrieved from tftp or can be available locally
or can be absent.
If 'fdt_addr_r' environment variable is set and 'fdt' label is defined
retrieve 'fdt blob' from tftp. 'fdt_addr_r' is then passed along bootm
command.
If 'fdt_addr' is set and 'fdt blob' is not retrieved from the tftp pass
'fdt_addr' to bootm command. In this case 'fdt blob' will be available
at 'fdt_addr'.
If 'fdt_addr' is not set and 'fdt blob' is not retrieve from tftp pass
NULL to boot command. In this case 'fdt blob' is not required and absent.

FEC: Rework the TX wait mechanism
The mechanism waiting for transmission to finish in fec_send() now
relies on the E-bit being cleared in the TX buffer descriptor. In
case of data cache being on, this means invalidation of data cache
above this TX buffer descriptor on each test for the E-bit being
cleared.
Apparently, there is another way to check if the transmission did
complete. This is by checking the TDAR bit in the X_DES_ACTIVE
register. Reading a register does not need any data cache invalidation,
which is beneficial.
Rework the sequence that wait for completion of the transmission so that
the TDAR bit is tested first and afterwards check the E-bit being clear.
This cuts down the number of cache invalidation calls to one.

the 88E6xxx series from Marvell trough an MDIO link using indirect
adressing. This can be used if we do not want to use an EEPROM for the
configuration.
This driver is not generic and was not tested on other switches than the 88e6352. This is proposed as a first implementation that is somewhat
limited but works and that can be used as a basis for further
developments for this switch family.

Previously u-boot would initialize the network interface for every

means that the network is being reinitialized very often. On many

This patch checks for consecutive netconsole actions and leaves the
ethernet hardware initialized between them. It will still behave the
