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.

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.

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

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.

Before this commit, weak symbols were not overridden by non-weak symbols
found in archive libraries when linking with recent versions of
binutils. As stated in the System V ABI, "the link editor does not
extract archive members to resolve undefined weak symbols".
This commit changes all Makefiles to use partial linking (ld -r) instead
of creating library archives, which forces all symbols to participate in
linking, allowing non-weak symbols to override weak symbols as intended.
This approach is also used by Linux, from which the gmake function
cmd_link_o_target (defined in config.mk and used in all Makefiles) is
inspired.
The name of each former library archive is preserved except for
extensions which change from ".a" to ".o". This commit updates
references accordingly where needed, in particular in some linker
scripts.
This commit reveals board configurations that exclude some features but
include source files that depend these disabled features in the build,
resulting in undefined symbols. Known such cases include:
- disabling CMD_NET but not CMD_NFS;
- enabling CONFIG_OF_LIBFDT but not CONFIG_QE.

When this define was introduced, the idea was to provide a soft
migration path for ARM boards to get adapted to the new relocation
support. However, other recent changes led to a different
implementation (ELF relocation), where this no longer works. By now
CONFIG_SYS_ARM_WITHOUT_RELOC does not only not help any more, but it
actually hurts because it obfuscates the actual code by sprinkling it
with lots of dead and non-working debris.
So let's make a clean cut and drop CONFIG_SYS_ARM_WITHOUT_RELOC.

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

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.

Without these changes gd->ram_size is '0' which leads to incorrect relocation
when CONFIG_SYS_ARM_WITHOUT_RELOC is defined and the board does not boot.
We use get_ram_size to dynamically calculate the available RAM because it runs
on different board version with different ram, as suggested by Heiko in private
