cmd_nvedit.c: Add env exists command

env exists is a way to test (in hush) if an environment variable
exists.  A workaround existed using printenv but this new command
doesn't require all the stdout/stderr redirection to prevent
printing information to the screen.

Example:
$ set testexists 1
$ env exists testexists && echo "yes"
yes
$ env exists testexists || echo "no"
$ set testexists
$ env exists testexists && echo "yes"
$ env exists testexists || echo "no"
no
$

MAKEALL: rename boards_by_* functions to targets_by_*

We expect boards_by_* function to return the 7th filed, 'Target',
not the 6th field, 'Board name'.

So the function names, boards_by_* are a little misleading,
and should be renamed to targets_by_*.

The link rule `$(call cmd_link_o_target, $(OBJS) $(obj)kgdb.o)'
is weird.
kbdg.o is not included in $(OBJS) but linked into $(LIB)
and $(LIB) is not dependent on kgdb.o.
(Broken dependency tracking)

So,
    START   = start.o kgdb.o
shoud have been
    START   = start.o
    SOBJS   = kgdb.o

That is why this commit adds kgdb.o to obj-y, not to extra-y.

Makefile: prepare for using Kbuild-style Makefile

Every makefile in sub directories has common lines
at the top and the bottom.
This commit pushes the common parts into script/Makefile.build.

Going forward sub-makefiles only need to describe this part:

    COBJS := ...
    COBJS += ...
    SOBJS := ...

But using obj-y is preferable to prepare for switching to Kbuild.

The conventional (non-Kbuild) Makefile style is still supported.
This is achieved by greping the Makefile before entering into it.
U-Boot conventional sub makefiles always include some other makefiles.
So the build system searches a line beginning with "include" keyword
in the makefile in order to distinguish which style it is.
If the Makefile include a "include" line, we assume it is a conventional
U-Boot style. Otherwise, it is treated as a Kbuild-style makefile.

With this tweak, we can switch sub-makefiles
from U-Boot style to Kbuild style little by little.

obj-y := foo/
syntax (descending into the sub directory) is not supportd yet.
It will be implemented in the upcomming commit.

nand_util.c: Correct licensing

Prior to SPDX licensing this file was GPL-2.0 with Freescale granting
rights for "or later" for their contributed code.  We incorrectly moved
this file to GPL-2.0+, so correct it to GPL-2.0.  In addition we cannot
easily denote in the file where or what code is "or later", so just set
that aside for now and the file as a whole is GPL-2.0 regardless.

mmc: sdhci: Avoid commands errors by simple timeout adaptation.

Old command timeout value was too small and it caused I/O errors which
led to uncompleted read/write/erase operations and filesystem errors.
Timeout adaptation fixes this issue.

Changes in sdhci_send_command() function:
- change timeout variable to static
- increase default command timeout to 100 ms
- add definition of max command timeout value,
  which can be redefined in each board config file
- wait for card ready state for max defined time
  if it doesn't exceed defined maximum or return COMM_ERR

Once successfully increased timeout value will be used in next function
call. This fix was tested on Goni, Trats, Trats2 boards by testing UMS
on MMC storage.

Changes v2:
- move global variable cmd_timeout into function sdhci_send_command()
- change condition "==" to ">=" when comparing time with timeout
- print information about timeout increasing and card busy timeout

video: ipu_disp: Fix clock polarity logic

Currently the HDMI splash screen image quality on mx6solo does not show a
very stable image.

By comparing the IPU driver from U-boot with the one from FSL 4.1.0 BSP,
we can see that there is an inverted logic for setting the DI_GEN_POL_CLK bit.

>From FSL BSP [1] we have:

if (!sig.clk_pol)
di_gen |= DI_GEN_POLARITY_DISP_CLK;

Applying the same logic into U-boot fixes the HDMI image stability.

mpc85xx: introduce the kmp204x reference design support

This patch introduces the support for Keymile's kmp204x reference
design. This design is based on Freescale's P2040/P2041 SoC.

The peripherals used by this design are:
- DDR3 RAM with SPD support
- SPI NOR Flash as boot medium
- NAND Flash
- 2 PCIe busses (hosts 1 and 3)
- 3 FMAN Ethernet devices (FMAN1 DTSEC1/2/5)
- 3 Local Bus windows, with one dedicated to the QRIO reset/power mgmt
  FPGA
- 2 HW I2C busses
- last but not least, the mandatory serial port

The board/keymile/kmp204x code is mostly based on Freescale's P2041rdb
support and was changed according to our design (that means essentially
removing what is not present on the designs and a few adaptations).

There is currently only one prototype board that is based on this design
and this patch also introduces it. The board is called kmlion1.
