With multiple environments, the 'get_char' callback for env
drivers does not really make sense any more because it is
only supported by two drivers (eeprom and nvram).

To restore single character loading for these drivers,
override 'env_get_char_spec'.

Commit 7d714a24 ("env: Support multiple environments") added
static variable env_load_location. When saving environmental
variables, this variable is presumed to have the value set before.
In case the value was set before relocation and U-Boot runs from a
NOR flash, this variable wasn't writable. This causes failure when
saving the environment. To save this location, global data must be
used instead.

ARC Elf32 tools by default enable usage of so-called "small data"
section or in ARC PRM parlance "GP-relative addressing".

The idea is to put up to 2kB of frequently used data into a separate
location and use indirect addressing via dedicated core register (GP).
Where GP is used as a base for offset calculation.

And so if "-msdata" toggle is passed to the compiler either explicitly
or implicitly (that's Elf32 tools case) it will try to put some data
in that "small data" area and then to calculate real offset from GP
to be encoded in instructions we need to know the base value which
liker gets from __SDATA_BEGIN__ symbol in hte linker script.

In U-Boot we don't use that feature and linker script doesn't define
__SDATA_BEGIN__ which gives us the following linkage error if we use
Elf32 tools:
------------------------->8-------------------
  LD      u-boot
.../bin/arc-elf32-ld.bfd: Error: Linker symbol __SDATA_BEGIN__ not found
.../bin/arc-elf32-ld.bfd: final link failed: Bad value
------------------------->8-------------------

Note if uClibc or glibc tools are used that problem doesn't happen
because usage of "small data section" is disabled by default as not very
useful for bigger executables. Moreover GP is just another name of r26
so we're loosing 1 core register which is not used by the compiler as a
generic register with "-msdata".

With commit 9bd76b80 ("spl: make CONFIG_OF_EMBED pass dts through

cmd_fdtgrep was now unknown in scripts/Makefile.spl after moving
it to dts/Makefile. This bug has been introduced with v2018.01.

This patch moves cmd_fdtgrep from dts/Makefile to scripts/Makefile.lib

ATF recently began announcing PSCI v1.1. Since that version is unknown
to u-boot, the PSCI device nodes were not updated.

Switch from the case statement to a greater/less-than comparison so that
v1.1, as well as future versions, get at least the compatible nodes of
known versions.

PSCI v1.1 doesn't seem to have introduced a new corresponding compatible.

>From DFU_ALT_INFO_EMMC (include/environment/ti/dfu.h) we can see that
rootfs will be flashed to second partition on eMMC. But at the moment we
have only one partition in $partitions environment variable. Let's add
"bootloader" partition prior to "rootfs", so that DFU works correctly.
This also fixes eMMC boot, which looks for rootfs on second partition.

"bootloader" partition start corresponds to "u-boot.img.raw" in DFU
eMMC info, which is 0x300 sector (384 KiB offset from eMMC start).

rootfs start address can be also found from DFU eMMC info.
bootloader-related area is finished at 0x1500 sector (2688 KiB offset
from eMMC start). This should be the start address for rootfs in
$partitions environment variable.

While at it, fix U-Boot environment address to be the same as for
AM57x EVM, so that it doesn't clash with other partitions.

So now eMMC layout looks like this:

    ===============================================================

    0       +------------------------+
            | MBR/GPT header         |   128           -

            | MLO                    |   256           -
    384     +------------------------+
            | u-boot.img             |   1792          bootloader
    2176    +------------------------+
            | //////// hole //////// |   256           -

            | U-Boot environment     |   128           -

            | U-Boot environment     |   128           -
            | (redundant)            |
    2688    +------------------------+
            | rootfs                 |   remaining     rootfs
    end     +------------------------+

    ===============================================================

"hole" area can be used further for storing U-Boot environment (like
it's done in AM57x EVM config file) or for increasing u-boot.img area
(in case u-boot.img size increased, e.g. if new dtbs were added).
