Update the L2 AUX CTRL settings for the SoCFPGA.
Enabling D and I prefetch bits helps improve SDRAM performance on the
platform.
Also, we need to enable bit 22 of the L2. By not having bit 22 set in the
PL310 Auxiliary Control register (shared attribute override enable) has the
side effect of transforming Normal Shared Non-cacheable reads into Cacheable
no-allocate reads.
Coherent DMA buffers in Linux always have a Cacheable alias via the
kernel linear mapping and the processor can speculatively load cache
lines into the PL310 controller. With bit 22 cleared, Non-cacheable
reads would unexpectedly hit such cache lines leading to buffer
corruption.

Now that we're actually converting the QTS-generated header files,
we can even adjust their data types. A good candidate for this is
the pinmux table, where each entry can have value in the range of
0..3, but each element is declared as unsigned long. By changing
the type to u8, we can save over 600 Bytes from the SPL, so do it.

The board/altera/socfpga directory is not a generic SoCFPGA machine
anymore, but instead it represents the Altera SoCDK board. To make
matters more complicated, it represents both CycloneV and ArriaV
variant.
On the other hand, nowadays, the content of this board directory is
mostly comprised of QTS-generated header files, while all the generic
code is in arch/arm/mach-socfpga already.
Thus, this patch splits the board/altera/socfpga into a separate
board directory for ArriaV SoCDK and CycloneV SoCDK, so that each
can be populated with the correct QTS-generated header files for
that particular board.

The CONFIG_TARGET_SOCFPGA_CYCLONE5 and CONFIG_TARGET_SOCFPGA_ARRIA5
selected both a board and a CPU. This is not correct as these macros
are supposed to select only board.
All would be good, if QTS-generated header files didn't check for
these macros exactly to determine if the platform is Cyclone V or
Arria V. Thus, for the sake of compatibility with not well fleshed
out header file generator, this patch makes these two macros into
a stub config option and introduces new CONFIG_TARGET_SOCFPGA_CYCLONE5_SOCDK
and CONFIG_TARGET_SOCFPGA_ARRIA5_SOCDK targets, which select the
previous stub config option.
The result is that compatibility with QTS is preserved and the new
CONFIG_TARGET_* select actual target boards.

Based on observation, this udelay(20) was apparently too high and caused
subsequent failure to calibrate DDR when U-Boot was compiled with certain

it to calculate the precise delay.

Introduce accessor iocsr_get_config_table() for retrieving IOCSR config
tables. This patch is again trimming down the namespace polution.
The IOCSR config tables are used only by scan manager, they are generated
by qts and are board specific. Before this patch, the approach to use
these tables in scan manager was to define an extern variable to silence
the compiler and compile board-specific iocsr_config.c into U-Boot which
defined those extern variables. Furthermore, since these are tables and
the scan manager needs to know the size of those tables, iocsr_config.h
is included build-wide.
This patch wraps all this into a single accessor which takes the scan
chain ID and returns pointer to the table and it's size. All this is
wrapped in wrap_iocsr_config.c board-specific file. The file includes
the iocsr_config.c (!) to access the original tables and transitively
iocsr_config.h . It is thus no longer necessary to include iocsr_config.h
build-wide and the namespace polution is trimmed some more.
