The older 'mr' variant and the generic variant of the
OT1200 differ in some places. As the name suggests the
generic variant supports more boot devices.
In order to be compatible with the 'mr' variant we define
some 'feature' GPIOs. On the 'mr' variant this pads are
not connected so we define their state with the help
of the internal pullups.
On the generic variant this GPIOs are connected and
represent the state of the hardware.

Commit 155fa9af95 changed the way
to define a GPIO line, which can be used to force CS high

change board code to make use of board_spi_cs_gpio(..).

This patch adds I2C support for the SoCFPGA. Using the designware I2C
controller driver. It supports all 4 I2C busses on the SoCFPGA.
The designware I2C driver has now been converted to the
CONFIG_SYS_I2C framework. So lets enable it on SoCFPGA.
Tested on SoCrates.

This commit relocates the exception vectors.
As ARM1176 and ARMv7 have the security extensions, it uses VBAR. For
the other ARM processors, it copies the relocated exception vectors to
the correct address: 0x00000000 or 0xFFFF0000.

A regression was introduced in commit 41623c91. The consequence of that
is the non-relocation of the section .vectors symbols :
_undefined_instruction, _software_interrupt, _prefetch_abort,
_data_abort, _not_used, _irq and _fiq.
Before commit 41623c91, the exception vectors were in a .text section.
The .text section has the attributes allocatable and executable [1].
In commit 41623c91, a specific section is created, called .vectors, with
the attribute executable only.
What have changed between commit 41623c91^ and 41623c91 is the attribute
of the section which contains the exception vectors.
An allocatable section is "a section [that] occupies memory during
process execution" [1] which is the case of the section .vectors.
Adding the lacking attribute (SHF_ALLOC or "a") for the definition of
the section .vectors fixed the issue.
To summarize, the fix has to mark .vectors as allocatable because the
exception vectors reside in "memory during execution" and they need to
be relocated.

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.

In preparation for the SoCFPGA support of the designware I2C driver,
convert this driver to the common CONFIG_SYS_I2C framework.
This patch converts all users of this driver, this is:
- ST spearxxx boards
- AXS101 (ARC700 platform)
I couldn't test this patch on those boards. Only compile tested for all
spear boards. And tested on SoCFPGA.

This patch permeates the struct i2c_adapter throughout the driver,
so that it can be used to determine which adapter should be used.
Note that the driver still supports only one adapter. Note that
the patch does shuffle mxs_i2c_set_bus_speed() to the top of the
driver, but the function remains unchanged.
