The low-level debugging functions are useful to debug the early boot
stage where the full UART driver is not available.
UniPhier SoCs need to initialize the UART port 0 to use this feature.
The initialization routine is called at the very entry of the
lowlevel_init().

For NAND boot on PH1-LD4, PH1-sLD8, and some other SoCs,
the output of the system bus is disabled by default.
It must be enabled by software to have access to the system bus.

The max size of available memories on slot0 and slot1 is 32MB because
- EA[25] signal is not output on the save-pin mode which is
used PH1-LD4 or later SoCs.
- EA[25] signal is not connected by the limitation (or bug?) of
the PLD logic of DCC support card.

This commit adds a dump command of DDR PHY parameters of UniPhier
SoC family. It might not be used very often for the regular operation
but it would be useful when something goes wrong with DDR memories.

Some UniPhier boards are equipped with an expansion slot that
some optional SRAM/NOR-flash cards can be attached to. So, run-time
detection of the number of flash banks would be more user-friendly.
Until this commit, UniPhier boards have achieved this by (ab)using
board_flash_wp_on() because the boot failed if flash_size got zero.
Fortunately, this problem was solved by commit 70879a9256 (flash:
do not fail even if flash_size is zero).
Now it is possible to throw away such a tricky workaround. This
commit also enables CONFIG_SYS_MAX_FLASH_BANKS_DETECT for further
refactoring.

Some configurations have been moved to Kconfig and the difference
among the config headers of UniPhier SoC variants is getting smaller
and smaller. Now is a good time to merge them into a single file.

There are two kinds of expansion boards which are often used for
the UniPhier platform and they are only exclusively selectable.
It can be better described by the "choice" menu of Kconfig.

If CONFIG_OF_CONTROL is defined, search device tree nodes that are
compatible with "panasonic,uniphier-ehci" and take the base address
from their "reg" property.

CONFIG_UNIPHIER_SERIAL has been moved to Kconfig and
it is defined in ./.config but not in spl/.config,
so pin_init() should be called from the normal image
so that UART works correctly.

Support EHCI host driver used on Panasonic UniPhier platform.
Since Device Tree is not supported on UniPhier yet, the base address
of USB cores are passed from board files (platdevice.c).
TODO for me:
Move the base address to device trees.

If a support card is attached to the main board, the on-board
SMSC9118 LAN controller is available. It must be kept in reset
state for a while on start-up.
When the board is kicked via a debbuger rather than pushing the
hardware reset button, on-board chips are not reset; in this case
the reset signals should be asserted by software.

This commit introduces a Kconfig symbol for each ARM CPU:
CPU_ARM720T, CPU_ARM920T, CPU_ARM926EJS, CPU_ARM946ES, CPU_ARM1136,
CPU_ARM1176, CPU_V7, CPU_PXA, CPU_SA1100.
Also, it adds the CPU feature Kconfig symbol HAS_VBAR which is selected
for CPU_ARM1176 and CPU_V7.
For each target, the corresponding CPU is selected and the definition of
SYS_CPU in the corresponding Kconfig file is removed.
Also, it removes redundant "string" type in some Kconfig files.

This commit converts UniPhier on-chip serial driver to driver model.
Since UniPhier SoCs do not have Device Tree support, some board files
should be added under arch/arm/cpu/armv7/uniphier/ph1-*/ directories.
(Device Tree support for UniPhier platform is still under way.)
Now the base address and master clock frequency are passed from
platform data, so CONFIG_SYS_UNIPHIER_SERIAL_BASE* and
CONFIG_SYS_UNIPHIER_UART_CLK should be removed.
Tested on UniPhier PH1-LD4 ref board.
