50c54a57df ethoc: clear only pending irqs
This patch fixed the problem of dropped packets due to lost of
interrupt requests. We should only clear what was pending at the
moment we read the irq source reg.

d43c36dc6b headers: remove sched.h from interrupt.h
After m68k's task_thread_info() doesn't refer to current,
it's possible to remove sched.h from interrupt.h and not break m68k!
Many thanks to Heiko Carstens for allowing this.

0baa080c75 ethoc: use system memory as buffer
This patch enabled the ethoc to allocate system memory as buffer
when there is no dedicated buffer memory.

Some hardware designs may not have dedicated buffer memory such as
on chip or off chip SRAM. In this case, only one memory resource is
supplied in the platform data instead of two. Then a DMA buffer can
be allocated from system memory and used for the transfer.

050f91dcd9 ethoc: align received packet to make IP header at word boundary
The packet buffer is allocated at 4 bytes boundary, but the IP header
length and version bits is located at byte 14. These bit fields access
as 32 bits word and caused exception on processors that do not support
unaligned access.

The patch adds 2 bytes offset to make the bit fields word aligned.

3ee19a85bb ethoc: fix buffer address mapping
The pointer address in buffer descriptors is physical address. The
pointer that processor used to access packet is virtual address.

Though the higher bits of pointer address used by the MAC may be
truncated to zero in special case, it is not always true in larger
designs.

a170285772 net: Add support for the OpenCores 10/100 Mbps Ethernet MAC.
This patch adds a platform device driver that supports the OpenCores 10/100
Mbps Ethernet MAC.

The driver expects three resources: one IORESOURCE_MEM resource defines the
memory region for the core's memory-mapped registers while a second
IORESOURCE_MEM resource defines the network packet buffer space. The third
resource, of type IORESOURCE_IRQ, associates an interrupt with the driver.
