add support for DSP wake-up by default on DA850/OMAP-L138
during board initialization. Enable hwconfig environment and added
extra env setting through CONFIG_EXTRA_ENV_SETTINGS.
To prevent DSP from being woken up,set the environment variable as,
set hwconfig "dsp:wake=no"

Some of the LPSC constants were incorrect, and some were missing. This

There are two main sets of LPSC constants, depending on the processor
family. The DA8xx constants were given in an enum whereas the non-DA8xx
constants were preprocessor defines. This commit switches the DA8xx
constants to defines for consistency.

The function davinci_emac_mii_mode_sel() is defined in
board/davinci/common/misc.c for any DA8xx CPU which has
CONFIG_DRIVER_TI_EMAC enabled. However, the prototype was only being
declared in <include/asm/arch/davinci_misc.h> for the DA850 EVM board.
This patch declares it for all DA8xx CPUs where CONFIG_DRIVER_TI_EMAC
is enabled.

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.

The patch adds basic board support for TI's OMAP-L138 based
Hawkboard. This board is pretty similar to the da850 EVM. Support for
nand and network access is added in this version.
The following bootup procedure is used.
At reset, the Rom Boot Loader(RBL), initialises the ddr and the nand
controllers and copies the second stage bootloader(nand_spl) to
RAM. The secondary bootloader then copies u-boot from a predefined
location in the nand flash to the RAM, and passes control to the
u-boot image.
Three config options are supported
* hawkboard_config - Used to create the u-boot.bin. Tftp the
u-boot.bin image to the RAM from u-boot, and flash to the nand flash
at address 0xe0000.
* hawkboard_nand_config - Used to generate the secondary
bootloader(nand_spl) image. This creates an elf file u-boot-spl
under nand_spl/. Create an AIS signed image using this file, and
flash it to the nand flash at address 0x20000. The ais file should
fit in one block.
* hawkboard_uart_config - This is same as the first image, but with
the TEXT_BASE as expected by the RBL(0xc1080000). Create the AIS

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.
