In case of multilib-enabled toolchains if default architecture differ from
the one examples are being built for linker will fail to link example object
files with libgcc of another (non-compatible) architecture.

Interesting enough for years in main Makefile we used CFLAGS/c_flags for this
but not for examples.

So fixing it now.

Conflicts:
	boards.cfg

Conflicts were trivial once u-boot-arm/master boards.cfg was
reformatted (commit 6130c146) to match u-boot/master's own
reformatting (commit 1b37fa83).

In SPL framework, SPL uses u-boot.img to load u-boot.bin.
Here,
    u-boot.img = uImage header + u-boot.bin

To use OF control with a separate devicetree,
u-boot.dtb must be placed right after u-boot.bin.
In this case, u-boot-dtb.bin is generally used.
Here,
    u-boot-dtb.bin = u-boot.bin + u-boot.dtb

We need u-boot-dtb.img to use both SPL framework
and separate OF control at the same time.
    u-boot-dtb.img = uImage header + u-boot-dtb.bin

For example, Zynq boards already define all of
  - CONFIG_SPL
  - CONFIG_OF_CONTROL
  - CONFIG_OF_SEPARATE

So, the support of u-boot-dtb.img is urgent.

cam_enc_4xx: convert to CONFIG_SPL_MAX_FOOTPRINT

replaced CONFIG_SPL_MAX_SIZE by CONFIG_SPL_MAX_FOOTPRINT. However,
CONFIG_SPL_MAX_SIZE is used in the Makefile for padding the SPL
when preparing an u-boot.ais image. By removing CONFIG_SPL_MAX_SIZE
said commits broke the ais image of the da850evm and cam_enc_4xx
configurations.

This patch converts the u-boot.ais target to use CONFIG_SPL_PAD_TO
instead of CONFIG_SPL_MAX_SIZE for padding the SPL and adds
a #define CONFIG_SPL_PAD_TO where it is required.

Trivial fix.

Using __DATE__, __TIME__ would make the build non-deterministic.

If the code needs to refer to build date/time, use U_BOOT_DATE and
U_BOOT_TIME in include/generated/timestamp_autogenerated.h instead.

which should be applied to U-Boot too:

    commit fe7c36c7bde12190341722af69358e42171162f3

    Makefile: Build with -Werror=date-time if the compiler supports it

    GCC 4.9 and newer have a new warning -Wdate-time, which warns on any use
    of __DATE__, __TIME__, or __TIMESTAMP__, which would make the build
    non-deterministic.  Now that the kernel does not use any of those
    macros, turn on -Werror=date-time if available, to keep it that way.

    The kernel already (optionally) records this information at build time
    in a single place; other kernel code should not duplicate that.
