By rearranging the functions in the semihosting code we can
avoid forward-declaration of the internal static functions.
This puts the stuff in a logical order: read/open/close/len
and then higher-order functions follow at the end.

There is currently a regression when using newer ARM64 compilers
for semihosting: the way long types are inferred from context
is no longer the same.
The semihosting runtime uses long and size_t, so use this
explicitly in the semihosting code and interface, and voila:
the code now works again.
Tested with aarch64-linux-gnu-gcc: Linaro GCC 4.9-2014.09.

The semihosting code exposes internal file handle handling
functions to read(), open(), close() and get the length of
a certain file handle.
However the code using it is only interested in either
reading and entire named file into memory or getting the
file length of a file referred by name. No file handles
are used.
Thus make the file handle code internal to this file by
removing these functions from the semihosting header file
and staticize them.
This gives us some freedom to rearrange the semihosting
code without affecting the external interface.

Implement an API that can be used by drivers to allocate memory from a
pool that is mapped uncached. This is useful if drivers would otherwise
need to do extensive cache maintenance (or explicitly maintaining the
cache isn't safe).
The API is protected using the new CONFIG_SYS_NONCACHED_MEMORY setting.
Boards can set this to the size to be used for the non-cached area. The
area will typically be right below the malloc() area, but architectures
should take care of aligning the beginning and end of the area to honor
any mapping restrictions. Architectures must also ensure that mappings
established for this area do not overlap with the malloc() area (which
should remain cached for improved performance).
While the API is currently only implemented for ARM v7, it should be
generic enough to allow other architectures to implement it as well.

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.

Introduce a Makefile under arch/$ARCH/ and include it in the

refactoringi like moving architecture-specific code out of global
makefiles, deprecating config variables (CPU, CPUDIR, SOC) or
deprecating arch/$ARCH/config.mk.
In contrary to Linux kernel, U-Boot defines the ARCH variable by
Kconfig, thus the arch Makefile can only included conditionally

Detect the board revision early during boot, and print the decoded
model name.
Eventually, this information can be used for tasks such as:
- Allowing/preventing USB device mode; some models have a USB device on-
board so only host mode makes sense. Others connect the SoC directly
to the USB connector, so device-mode might make sense.
- The on-board USB hub/Ethernet requires different GPIOs to enable it,
although luckily the default appears to be fine so far.
- The compute module contains an on-board eMMC device, so we could store
the environment there. Other models use an SD card and so don't support
saving the environment (unless we store it in a file on the FAT boot
partition...)
Set $fdtfile based on this information. At present, the mainline Linux
kernel doesn't contain a separate DTB for most models, but I hope that
will change soon.

CONFIG_OF_CONTROL must have <asm/arch/gpio.h> even if they do not
support GPIO.
In the first place, GPIO has nothing to do with OF_CONTROL.
It is wrong that lib/fdtdec.c includes GPIO functions; it should
be split into two files, FDT-common things and GPIO things.
It is, however, a pretty big work to fix that correctly.

Currently cpu_init_interrupts() is called from cpu_init_r() to
setup the interrupt and exception of the cpu core, but at that
time the i8259 has not been initialized to mask all the irqs
and remap the master i8259 interrupt vector base, so the whole
system is at risk of being interrupted, and if interrupted,
wrong interrupt/exception message is shown.

Intel chips have a turbo mode where they can run faster for a short period
until they reach thermal limits. Add code to adjust and query this feature.

These peripherals should not be at the top level, since they exist inside
the PCI bus. We don't have a full device tree node for pci yet, but we
should at least put it at the right level.

Define the reset base in config.mk so that it does not need to be calculated
twice in the link script. Also tidy up the START_16 and RESET_VEC_LOC values
to fit with this new approach.

Some toolchains put the relocation data into separate sections. Adjust the
linker script to catch this case. Without relocation data, U-Boot will not
boot.

This normally indicates a problem which will prevent relocation from
functioning, resulting in a hang. Panic in this case to make it easier
to debug.
