there are two boards based on da850 SOC - OMAP-L138 and AM18x.
In order to differentiate between these two boards, revision id
is passed to kernel via second byte of ATAG_REVISION.

The boards in board/davinci/da8xxevm/ define pinmux_config[] vectors
that contain pinmux configurations for emac, uarts, memory controllers...
In an earlier patch such pinmux configurations were added to the arch
tree. This patch makes the da850evm use these definitions instead of
defining its own.

Since commit f1d2b313c9 the serial
port of the da850evm is accessed before the UART2 peripheral of
the SoC is powered on in the function board_init() in
board/davinci/da8xxevm/da850evm.c.
When u-boot is used in conjunction with the UBL (user boot loader, see
doc/README.davinci) on this board, the UART2 peripheral is already
turned on by UBL at the time u-boot is started. Hence, the wrong
initialization sequence is not noticed by most users. However, if UBL is not
used, u-boot must power on the peripheral before using it.
This patch adds a board_early_init_f() function for the LPSC
configuration to the da850evm board configuration.

The current NAND timings, introduced in commit
a3f88293dd da850evm: setup the NAND flash
timings , incorrectly set WSTROBE and TA to 0. A more recent inspection of the
values set by the Linux kernel indicates that these should be set to 1.
Set the WSTROBE and TA field of the EMIFA cycle-count timings configuration to
1 to match the values set by linux.

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 TI DA850/OMAP-L138/AM18x EVM can be populated with devices
having different maximum allowed CPU clock rating.
The maximum clock the chip can support can only be determined from
the label on the package (not software readable).
Introduce a method to pass the maximum allowed clock rate information
to kernel using ATAG_REVISION. The kernel uses this information to
determine the maximum cpu clock rate reachable using cpufreq.
Note that U-Boot itself does not set the CPU clock rate. The CPU
clock is setup by a primary bootloader ("UBL"). The rate setup by
UBL could be different from the maximum clock rate supported by the
device.

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.

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.

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.
