DaVinci EMAC is present on TI AM35xx SoCs (ARMv7) which run with D-Cache
enabled by default. So we have to take care and flush/invalidate the
cache before/after the DMA operations.
Please note that the receive buffer alignment to 32 byte boundary comes
from the old driver version I don't know if it is really needed or
alignment to cache line size is enough.

DaVinci EMAC is found not only on DaVinci SoCs but on some OMAP3 SoCs
also. This patch moves common defines from arch-davinci/emac_defs.h to
drivers/net/davinci_emac.h
DaVinci specific PHY drivers hacked to include the new header. We might
want to switch to phylib in future.

remove macro CONFIG_EMAC_MDIO_PHY_NUM and depending macro EMAC_MDIO_PHY_NUM
as they are no longer needed with the support for more than 1 PHYs in davinci
emac driver.

Added arch/arm/cpu/arm926ejs/davinci/et1011c.c for handling
ET1011C gigabit phy. which overrides get_link_speed function
from default implementation. This enables output of 125 MHz
reference clock on SYS_CLK pin.

This patch proposes to migrate the davinci_emac driver to using the
eth_device->write_hwaddr function pointer as suggested by Ben Warren.
All the davinci boards had the behaviour, prior to this patch, of
sync'ing the environment variable enetaddr with the MAC address read
from non-volatile storage on boot -- when the two locations disagreed,
the environment variable value took precendence. This patch keeps the
same behaviour but lets eth_initialize take care of it.
This patch refactors davinci_emac setup in the boards so that the MAC
address is read from non-volatile storage into the environment variable
and then the environment variable value is use in eth_intialize. The
only exception is the direct call to davinci_eth_set_mac_addr made by
the da830evm board init which was changed into an assignment of the
enetaddr field.

Currently EMAC_MDIO_PHY_NUM is defined as 1 in emac_defs.h.
Because of this, EMAC does not work on EVMs which do not have phy
connected at 1. Moving the macro to board config file makes this
configurable depending on where the phy is connected on the MDIO bus.
This patch fixes the board reset issue observed during network access
on DM365EVM. EMAC driver was assuming EMAC_MDIO_PHY_NUM as 1
but it is 0 on DM365EVM.
This patch is verified on da830/omap-l137, dm365 and dm644x evms.

This helps to clean up the include/ directory so that it only contains
non-architecture-specific headers and also matches Linux's directory
layout which many U-Boot developers are already familiar with.

Adds support for ethernet networking on the da830evm platform.
This platform uses an SoC EMAC interface and a 3 port ethernet
switch as a PHY with an RMII interface. The PHY also has a i2c
interface for configuring the switch functions.

The EMAC IP on DM365, DM646x and DA830 is slightly different
from that on DM644x. This change updates the DaVinci EMAC driver
so that EMAC becomes operational on SOCs with EMAC v2.

In the DaVinci specific code, we use both CONFIG_SOC_DM646X and
CONFIG_SOC_DM646x to represent DM646x specific code.
This patch changes occurrences of CONFIG_SOC_DM646x to
CONFIG_SOC_DM646X. This is because for DM644x series of SOCs we use
the flag CONFIG_SOC_DM644X. We want some uniformity.

Different flavours of DaVinci SOC's have differences in their EMAC IP
This patch does the following
1) Updates base addresses for DM365
2) Updates MDIO frequencies for DM365 and DM646x
3) Update EMAC wrapper registers for DM365 and DM646x
Patch applies to u-boot-net git. the EMAC driver itself
will be updated shortly to add support for DM365 and DM646x

Add support for the following DaVinci boards:
- DV_EVM
- SCHMOOGIE
- SONATA
Changes:
- Split into separate board directories
- Removed changes to MTD_DEBUG (or whatever it's called)
- New CONFIG_CMD party line followed
- Some cosmetic fixes, cleanup etc.
- Patches against the latest U-Boot tree as of now.
- Fixed CONFIG_CMD_NET in net files.
- Fixed CONFIG_CMD_EEPROM for schmoogie.
- Made sure it compiles and works (forceenv() link problem) on SCHMOOGIE and
DV_EVM. Can't check if it works on SONATA, don't have a board any more,
but it at least compiles.
Here is an excerpt from session log on SCHMOOGIE...
