6d1c649f44 Davinci 8xx: Move common functions to share code
As more Davinci 8xx board can be added, move common code
to be shared between boards.

 * rebased ontop of Sugosh's patches
 * moving the HAWKBOARD_KICK{0,1}_UNLOCK defines to
   arch/arm/include/asm/arch-davinci/davinci_misc.h from to
   arch/arm/include/asm/arch-davinci/da8xx_common.h
 * don't define dram functions in PRELOADER
 * move sync_env_enetaddr into existing EMAC ifdef
 * use misc.c in hawkboard nand_spl

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.

4f6fc15b42 DA850 EVM: passing maximum clock rate information to kernel
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.

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.
