This patch moves the davinci i2c_defs.h file to drivers.i2c directory.
It will allow to reuse the davinci_i2c driver for TI Keystone2 SOCs.

Not used "git mv" command to move the file because small part of
it with definitions specific for Davinci SOCs has to remain in the
arch/arm/include/asm/arch-davinci.

We previously only supported QSPI_1 (single) support.  Add QSPI_4 (quad)
read support as well.  This means we can be given one of two boot device
values, but don't care which it is, so perform a fixup on the QSPI_4
value.  We add a qspiboot build target to better show how you would use
QSPI as a boot device in deployment.  When we boot from QSPI, we can
check the environment for 'boot_os' to control Falcon Mode.

This is only useful with the _spiboot build target anyhow, so only
include it then.  Drop CONFIG_SPL_OS_BOOT support then as the flash is
small and didn't include a spot for the device tree already.

To deal with a reoccurring problem properly we need to specify addresses
for the Linux kernel, Flatted Device Tree and ramdisk that obey the
constraints within the kernel's Documentation/arm/Booting file but also
make sure that we relocate things within a valid address range.

It is possible with these addresses to also set fdt_high and initrd_high
to the value of 0xffffffff.  We don't do this by default to allow for
the most likely success of people using custom addresses however.

Inside of SPL we only concern ourself with one MMC device, so instead of
being able to use CONFIG_SYS_MMC_ENV_DEV we need to use 0 in SPL.
Switch the code to use a 'dev' variable to facilitate this.
Signed-off-by: NTom Rini <trini@ti.com>

We currently limit ourself to 16 characters for the device name to read
the environment from.  This is insufficient for /dev/mmcblk0boot1 to
work for example.  Switch to '%ms' which gives us a dynamically
allocated buffer instead.  We're short lived enough to not bother
free()ing the buffer.

introduce get_die_id() function which allows generation of
information such as fake MAC address from the processor ID code.
Signed-off-by: NNishanth Menon <nm@ti.com>

TI platforms such as OMAP5uevm, PandaBoard, use equivalent
logic to generate fake USB MAC address from device unique DIE ID.

Consolidate this to a generic location such that other TI platforms such
as BeagleBoard-XM can also use the same.

NOTE: at this point in time, I dont yet see a need for a generic dummy
ethernet MAC address creation function, but if there is a need in the
future, this can be further abstracted out.

Replace the custom bit manipulation function sr32() by standard I/O
accessors.  A major motivation for this cleanup was the fact, that a
number of calls of that function resulted in 32 bit wide shift
operations on u32 data, which according to the C-ISO/IEC-9899-Standard
provokes undefined behaviour:

	6.5.7 Bitwise shift operators
	...
        If the value of the right operand is negative or is greater
        than or equal to the width of the promoted left operand, the
        behavior is undefined.

In some use cases, SPL linker script was not updated even when
it should be.

For instance,

  $ make tricoder_config all
    [ build complete ]
  ... modify include/configs/tricoder.h
  $ make

spl/u-boot-spl.lds should be updated in this case, but it wasn't.

To fix this problem, linker scripts generation should be handled
by $(call if_changed_dep,...) rather than by $(call if_changed,...).

This patch add gicv3 support to uboot armv8 platform.

Changes for v2:
  - rename arm/cpu/armv8/gic.S with arm/lib/gic_64.S
  - move smp_kick_all_cpus() from gic.S to start.S, it would be
    implementation dependent.
  - Each core initialize it's own ReDistributor instead of master
