Add build target for generating boot partition images recognised by
the SoCFPGA BootROM. The SoCFPGA BootROM expects four copies of the
u-boot-spl-dtb.sfp at the beginning of boot partition. Those are
u-boot-spl-dtb.bin augmented by a header with which the BootROM can
work. The u-boot-dtb.img uImage is appended to this to produce a
full boot partition image, the u-boot-with-spl-dtb.sfp . This is
the name of the final target.

Setting LOADADDR to 0x8000 is a bad idea, it is very likely that
some kind of overlap will happen. Move the LOADADDR 0x01000000
(16MiB from start of RAM) to make sure no overlap happens when
loading kernel for example.

We do not need full MTD support in the SPL build, it only adds size

There is no need to disable support for partitions in the SPL,
we can support partitions in SPL perfectly well. This is likely
some remnant from old times, so just remove this configuration
option.
Moreover, the CRC32 chunk size doesn't have to be adjusted anymore,
since both the GD and malloc area are in RAM by the time this CRC
check can be used and there's plenty of space. Zap this abomination
as well.

Now that the SPL structure is organised such that it matches the
U-Boot's SPL design, it is possible to use the option of relocating
GD to RAM. And since we have GD in RAM, move malloc area to RAM as
well. We point the malloc base pointer 1 MiB past U-Boot's load
address. We use simple malloc for SPL because it is 3kiB smaller
in terms of code size than regular malloc which was used thus far.

Reset the GMAC ethernets based on the "resets" OF node instead of ad-hoc
hardcoded values in the U-Boot code. Since we don't have a proper reset
framework in place yet, we have to do this slightly ad-hoc parsing of the
OF tree instead.

Write necessary magic value into the Warm Boot from ON-Chip RAM
group Enable register to enable Warm reset support. Instead of
doing this in the reset_cpu() function, we do it in arch early
init to avoid breaking old kernel code which expects this magic
value to be already written into this register.
This magic is originally excavated from common/spl/spl.c in the
u-boot port from altera, where this value was written just before
the SPL jumped to actual U-Boot in the RAM.

The code in spl_board_init() should have been in board_init_f()
from the beginning, since it is code which configures system and
then starts DRAM. Thus, it cannot be in spl_board_init(), which
is called from board_init_r() , which already expects a working
DRAM.

Implement new accessor, sysmgr_get_pinmux_table(), used to obtain pinmux
table and it's size from the QTS-generated pinmux_config.c. The target
here is again to get rid of poluting global namespace by including the
pinmux_config.h into it.
Furthermore, the pinmux_config.h declares some CONFIG_HPS_* macros,
which are explicitly useless to us in U-Boot. Instead, U-Boot does
use DT to detect exactly these configuration options. This patch
makes sure that while this QTS-generated file can stay in the tree,
these obscure macros do not ooze into the namespace anymore.

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.

It is sufficient to pass in the scan chain ID into the function to determine
the remaining two parameters, so drop those params and determine them locally
in the function. The big-ish switch in the function is temporary and will be
replaced by a proper function call in subsequent patch.

Extract the clock configuration horribleness caused by pll_config.h in
the following manner.
First of all, introduce a few new accessors which return values of
various clocks used in clock_manager.c and use them in clock_manager.c .
These accessors replace those few macros which came from pll_config.h
originally. Also introduce an accessor which returns the struct cm_config
default configuration for the clock manager used in SPL.
The accessors are implemented in a board-specific wrap_pll_config.c
file, whose sole purpose is to include the qts-generated pll_config.h
and provide only the necessary values to the clock manager.
The purpose of this design is to limit the scope of inclusion for the
pll_config.h , which thus far was included build-wide and poluted the
namespace. With this change, the inclusion is limited to just the new
wrap_pll_config.c file, which in turn provides three simple functions
for the clock_manager.c to use.
