3d248d37e1 da850evm: basic MII EMAC support
The current da850evm support in u-boot/master omits any use of
the davinci EMAC. This patch adds basic support for the EMAC using
the MII PHY found on the baseboard of the EVM. The MAC address is
read from the environment variable 'ethadd'. Note that this is
different from the da850evm support in the u-boot omapl1 tree
where the MAC address is read from SPI flash.

a3f88293dd da850evm: setup the NAND flash timings
The default NAND flash timings are very conservative. This patch assigns the
timings reccomended in the recent linux kernel patch [1] from Sekhar Nori. The
speedup, as reported in that patch, is 5.3x for reads.

756d1fe7ac da850evm : enable NAND even when not in NAND boot mode
There is currently no NAND pinmux enabled by the da850evm board setup code.
This is fine when booting from NAND since the early boot code (UBL) will setup
the pinmux; however, when the boot mode is any other setting NAND is unusable
when enabled in the config.

This patch adds a pinmux list for NAND and enables it when NAND is enabled in
the config. Tested by booting from SPI on the da850evm and verifying NAND
was usable.

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.

37adbf9b12 da850 evm: Fix definition of 'pinmux' macro
Usage of parenthesis in pinmux macro definition changes the
definition of the macro and raises the precedence of '&'
operator inadvertently over '[]'.

b9f34ce94f da830 evm: Fix checkpatch error on 'pinmux' macro
Existing code returns checkpatch error on pinmux macro definition for
not enclosing the definition in parenthesis. The error can be observed in
the patch generated from commit id bdc9c6c7f7.
So macro implementation is modified to fix the error.

158557001a TI: DaVinci: Prepare for da850 support
DA850/OMAP-L138 is a new SoC from Texas Instruments
(http://focus.ti.com/docs/prod/folders/print/omap-l138.html).
This SoC is similar to DA830/OMAP-L137 in many aspects. Hence
rename the da830 specific files and folders to da8xx to
accommodate DA850/OMAP-L138.
