When your emulator is connected at reset (or is used to load u-boot)
it is possible to get the relocation address from the gd->relocaddr
since gd is always in r8 (on ARM) it is addressable before the
gdb has remapped symbols.

Document this alternate method in-line with the original method
written by Heiko Schocher.

The bdinfo command prints the relocaddr on ARM as it does
on PPC.

Update the debugging instructions for arm relocation to
reflect this fact rather than requiring that the user
rebuild the u-boot image using -DDEBUG.

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.

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.

Add the ability to not report an I2C POST error for a set of given I2C
addresses on bootup.  This is useful for cases when a device may or may
not be present, and neither case is considered an error.  For example:

- Some form factors such as XMC and Compact PCI Express have an I2C
  EEPROM whose address changes based on geographical address.  Eg
  installed in one slot its EEPROM address is, 0x50, in another its
  0x51, etc.  This allows multiple devices to have their EEPROMs present
  on the same I2C bus.  Thus the I2C devices present for an XMC or
  CPCIe card depend on if and where other cards are installed in the
  same system.

- Some cards have optional I2C devices.  Eg one hardware build
  configuration has different I2C devices than another and software
  can't determine if the optional device should be present or not.

- Some cards have optional daughtercards with I2C devices on them.

- I2C EEPROMs address range depends on their size.  Its possible to
  support differently size EEPROMs by only probing the EEPROM's base
  address and ignoring the other addresses that are impacted by its
  size.

A new CONFIG_SYS_POST_I2C_IGNORES define has been added which specifies
a list of I2C addresses for the I2C POST to ignore.

The memory test is performed after DDR initialization when U-boot stills runs
in flash and cache. On recent mpc85xx platforms, the total memory can be more
than 2GB. To cover whole memory, it needs be mapped 2GB at a time using a
sliding TLB window. After the testing, DDR is remapped with up to 2GB memory
from the lowest address as normal.

If memory test fails, DDR DIMM SPD and DDR controller registers are dumped for
further debugging.
