ARM: LPC32xx: Ethernet support
This patch adds ethernet support to the LPC32xx ARM architecture. The actual driver in drivers/net is contained in a separate patch. Signed-off-by: Roland Stigge <stigge@antcom.de> Acked-by: Arnd Bergmann <arnd@arndb.de>

help
|

Say Y here to use the LPC internal fast IRAM (i.e. 256KB SRAM) as
|
||||
network buffer. If the total combined required buffer sizes is
|
||||
larger than the size of IRAM, then SDRAM will be used instead.
|
||||
|
||||
This can be enabled safely if the IRAM is not intended for other
|
||||
uses.

bool "Check to enable MII support or leave disabled for RMII support"
|

help
|

Say Y here to enable MII support, or N for RMII support. Regardless of
|
||||
which support is selected, the ethernet interface driver needs to be
|
||||
selected in the device driver networking section.
|
||||
|
||||
The PHY3250 reference board uses RMII, so users of this board should
|
||||
say N.
