Due to size limitations of the MERAM, switch U-Boot to SPL.
The SPL is loaded by the SPI_LOADER into MERAM and then loads
U-Boot proper into DRAM. This way U-Boot can freely grow in
size in DRAM, as there is plenty of it.

NOTE: To update U-Boot, first install u-boot.img to 0x140000 in SPI NOR,
      then use the Minimon to flash u-boot-spl.srec using ls,2,e6304000.
      To generate u-boot-spl.srec, use objcopy:
        arm-linux-gnueabi-objcopy -O srec spl/u-boot-spl u-boot-spl.srec

Those two nodes are needed to configure pinmux before relocation
and to configure clock before relocation, since CPG/MSSR needs
access to RST node. This is not noticable on Gen3, but on Gen2
this causes problems in SPL if they are not available early.

Reset and initialize the PHY once in the probe() function rather than
doing it over and over again is start() function. This requires us to
keep the clock enabled while the driver is in use. This significantly
reduces the time between transfers as the PHY doesn't have to restart
autonegotiation between transfers, which takes forever.

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".

to u-boot, the PSCI device nodes were not updated.

Switch from the case statement to a greater/less-than comparison so that

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           -

            | 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).
