MPC824x: remove obsolete "PN62" board

2013-11-11T19:46:24+00:00

The MPC824x processors have long reached EOL, and the PN62 board has
not seen any board-specific updates for more than a decade.  It is now
causing build issues.  Instead of wasting time on things nobody is
interested in any more, we rather drop this board.

pcnet: enable the NOUFLO feature

2013-11-09T16:21:01+00:00

On relatively slow boards (such as the MIPS Malta with an FPGA core
card) it can be extremely common for transmits to underflow - to the
point where it appears they simply do not work at all. Setting the
NOUFLO bit causes the ethernet controller to not begin transmission on
the wire until a transmit start point is reached. Setting that transmit
start point to the full packet will cause the controller to only
transmit the packet once it has buffered it entirely thus preventing any
transmit underflows from occuring and allowing the controller to
function on slower boards.

pcnet: add cache flushing & invalidation

2013-11-09T16:21:01+00:00

Ensure that the view of memory from the CPU & the ethernet controller is
coherent at the various points where they exchange data. This prevents
stale data from being transmitted or received, and prevents the driver
from getting stuck waiting for the ethernet controller to update
descriptors when in reality it has but the old values are being read
from cache.

pcnet: s/le16_to_cpu/cpu_to_le16/ in pcnet_send

2013-11-09T16:21:01+00:00

This should cause no change to the generated code, but is semantically
correct.

pcnet: code style cleanup

2013-11-09T16:21:01+00:00

Fix up the code to match Documentation/CodingStyle. This is mostly
removing extraneous spaces.

No functional change is intended.

net: pcnet: use pci_virt_to_mem to obtain buffer addresses

2013-07-24T13:51:03+00:00

The pcnet driver uses the pci_phys_to_mem function
to get the memory address of the DMA buffers. This
This assumes an 1:1 mapping between the PCI and
physical memory which is not true on all platforms.

On MIPS platform U-Boot is running within a mapped
memory region, and the pci_phys_to_mem macro can't
be used to obtain the memory address of the buffers.

net: pcnet: Add initialized eth_device structure

2010-11-14T22:17:45+00:00

pcnet driver does not have write_hwaddr function.
However, eth stuff executes write_hwaddr function
because eth_device structure has not been initialized.
