ba511f779a da850: fix the channel number for EMAC teardown init
TX and RX channel numbers programmed as '1' during EMAC
teardown initialization is wrong. This patch fixes the
same by setting channel number to '0' which is used by U-boot.

7d2fade7b1 ea20: fix undefined PHY_* errors
This patch fixes ea20 after 8ef583a035 where
the u-boot custom PHY_ macros were replaced with those of linux/mii.h MII_
definitions except in the RMII support for davinci_emac. Probably also due to
the merge path of changes in 2010.12.

840f8923a0 DaVinci DM6467: Added ET1011C (LSI) PHY support
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.

2a7d603f37 DaVinci EMAC: Add name to Ethernet device
Adds "DaVinci-EMAC" as the name of the device so that
it gets printed as "Using DaVinci-EMAC device"
during network access (dhcp, tftp) instead of empty name
in "Using" statement.This name also gets
reflected in 'ethact' env variable.

4b9b9e7c66 DaVinci EMAC: Fix davinci_eth_gigabit_enable
Enabling the gigabit was overwriting the
previous configuration by setting up only GIGAFORCE and
GIG bits of MAC control register.
Modified to retain previous configuration while
gigabit enabling.

8ef583a035 miiphy: convert to linux/mii.h
The include/miiphy.h header duplicates a lot of things from linux/mii.h.
So punt all the things that overlap to keep the API simple and to make
merging between U-Boot and Linux simpler.

d26074012b da850: Add RMII support for EMAC
This patch is a port of the work by Sudhakar Rajeshekhara in commit
ab3effbcad8851cc65dc5241a01c064d2030a3b2 of
git://arago-project.org/git/people/sandeep/u-boot-davinci.git.

The da850 UI board has on it an RMII PHY which can be used if the MDC line
to the MII PHY on the baseboard is disabled and the RMII PHY is enabled by
configuring the values of some GPIO pins on the IO expander of the UI board.
This patch implements disabling that line via GPIO2[6], configuring the UI
board's IO expander and setting only the pinmux settings that are needed for
RMII operation.

Tested on da850evm by adding a define for CONFIG_DRIVER_TI_EMAC_USE_RMII.

7b37a27e14 davinci_emac: davinci_eth_set_mac_addr to ->write_hwaddr
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.

d7e354374c TI: DaVinci: Updating EMAC driver for DM365, DM646x and DA8XX
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.
