Before this commit, the stack addresses for IRQ and FIQ modes,
IRQ_STACK_START and FIQ_STACK_START, were computed in interrupt_init but
they were not used.

This commit sets the stack pointers for IRQ and FIQ modes.

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.

This file should contain the bin_hdr generated by the original Marvell
U-Boot implementation. As this is currently not included in this
U-Boot version, we have added this placeholder, so that the U-Boot
image can be generated without errors.

If you have a known to be working bin_hdr for your board, then you
just need to replace this text file here with the binary header
and recompile U-Boot.

In a few weeks, mainline U-Boot will get support to generate the
bin_hdr with the DDR training code itself. By implementing this code
as SPL U-Boot. Then this file will not be needed any more and will
get removed.
