ARCv2 cores may have built-in SLC (System Level Cache, AKA L2-cache).
This change adds functions required for controlling SLC:
* slc_enable/disable
* slc_flush/invalidate
For now we just disable SLC to escape DMA coherency issues until either:
* SLC flush/invalidate is supported in DMA APIin U-Boot
* hardware DMA coherency is implemented (that might be board specific
so probably we'll need to have a separate Kconfig option for
controlling SLC explicitly)

[1] Fix misspeling in ARC_CACHE_LINE_SHIFT dependency, now cache-line
lenth selection is correctly enabled if either I$ or D$ are enabled.
[2] Add dummy entry to target list to make sure target type is always
mentioned in defconfig. Otherwise defconfig for the first target in the
list will not have target name and later on with addition of the new
target on top of the list in Kconfig will lead to corrupted
configuration expanded from defconfig.

As discussed on mailing list we're drifting away from
CONFIG_SYS_GENERIC_GLOBAL_DATA in favour to use of board_init_f_mem()
for global data.
So do this for ARC architecture.

Intention behind this work was elimination of as much assembly-written
code as it is possible.
In case of ARC we already have relocation fix-up implemented in C so why
don't we use C for U-Boot copying, .bss zeroing etc.
It turned out x86 uses pretty similar approach so we re-used parts of
code in "board_f.c" initially implemented for x86.
Now assembly usage during init is limited to stack- and frame-pointer
setup before and after relocation.

This separation makes maintenance of code easier because those low-level
interrupt- or exception handling routines are pretty static and usually
require not much care while start-up code is a subject of modifications
and enhancements.

Even though ARCompact and ARCv2 are not binary compatible most of
assembly instructions are used in both. With this change we'll get rid
of duplicate code.
Still IVTs are implemented differently so we're keeping them in separate
files.

Make both invalidate_icache_all() and invalidate_dcache_all() available
even if U-Boot is configured with CONFIG_SYS_DCACHE_OFF and/or
CONFIG_SYS_ICACHE_OFF.
This is useful because configuration of U-Boot may not match actual
hardware features. Real board may have cache(s) but for some reason we
may want to run U-Boot with cache(s) disabled (for example if some
peripherals work improperly with existing drivers if data cache is
enabled). So board may start with cache(s) enabled (that's the case for
ARC cores with built-in caches) but early in U-Boot we disable cache(s)
and make sure all contents of data cache gets flushed in RAM.

To facilitate changing lowlevel_init to become s_init, move the current
contents of s_init into board_init_f and add the rest of what
board_init_f does here.
In order to compile clean without CONFIG_SKIP_LOWLEVEL_INIT set, leave an
empty stub of s_init(). It can be removed when lowlevel_init becomes s_init.

Even the 8-bit case needs KBCB configured, as pin D7 is located in this
pingroup.
Please note that pingroup ATC seems to come out of reset with its
config set to NAND so one needs to explicitly configure some other

outside the scope of this patch.

A while ago I got Russell to change the machine type of our Colibri T20
from COLIBRI_TEGRA2 to COLIBRI_T20 which at least in parts is also
reflected in his machine registry:

The usb0 / otg phy on sunxi boards has a bug where it wrongly detects a
high speed squelch on usb reset deassert when a lo speed device is plugged in.
The android kernel has a work around for this in the form of temporary
disabling the phy's squelch detection on reset deassert, this commit adds
the same workaround to the u-boot sunxi musb code, thereby fixing various usb
lo speed devices not working.

This option has a bool type, not hex.
Fix it and enable it if CONFIG_DM is on because Driver Model always
requires malloc memory. Devices are scanned twice, before/after
relocation. CONFIG_SYS_MALLOC_F should be enabled to use malloc
memory before relocation. As it is board-independent, handle it
globally.

My main motivations for this commit are:
[1] Follow the arch/arm/Makefile style of Linux Kernel
[2] Maintain compiler options systematically
Currently, we give -march=* and -mtune=* options inconsistently:
Only some of the CPUs pass -march=* and -mtune=* options.
By collecting such options into the single place arch/arm/Makefile
we can tell which options are missing at a glance.
[3] Prepare for deprecating arch/*/cpu/*/config.mk
Note:
This commit just moves the compiler options so as not to change
the behavior at all. It does not care about the correctness of
the given options. Fox example, "-march=armv5te" might be better
than "-march=armv4" for ARM946EJS, but it is beyond the scope this
commit. Also, filling the missing -march=* and -tune=* is left
to follow-up patches.
