armv7: add reset timeout to identify_nand_chip

identify_nand_chip hangs forever in loop when NAND is not present.
As IGEPv2 comes either with NAND or OneNAND flash, add reset timeout
to let function fail gracefully allowing caller to know NAND is
not present. On NAND equipped board, reset succeeds on first read,
so 1000 loops seems to be safe timeout.

ARM: tegra: add IVC protocol implementation

IVC (Inter-VM Communication) protocol is a Tegra-specific IPC (Inter
Processor Communication) framework. Within the context of U-Boot, it is
typically used for communication between the main CPU and various
auxiliary processors. In particular, it will be used to communicate with
the BPMP (Boot and Power Management Processor) on Tegra186 in order to
manipulate clocks and reset signals.

ARMv8: add the secure monitor firmware framework

This framework is introduced for ARMv8 secure monitor mode firmware.
The main functions of the framework are, on EL3, verify the firmware,
load it to the secure memory and jump into it, and while it returned
to U-Boot, do some necessary setups at the 'target exception level'
that is determined by the respective secure firmware.

So far, the framework support only FIT format image, and need to define
the name of which config node should be used in 'configurations' and
the name of property for the raw secure firmware image in that config.
The FIT image should be stored in Byte accessing memory, such as NOR
Flash, or else it should be copied to main memory to use this framework.

ARM: Add an empty secure stack section

Until now we've been using memory beyond psci_text_end as stack space
for the secure monitor or PSCI implementation, even if space was not
allocated for it.

This was partially fixed in ("ARM: allocate extra space for PSCI stack
in secure section during link phase"). However, calculating stack space
from psci_text_end in one place, while allocating the space in another
is error prone.

This patch adds a separate empty secure stack section, with space for
CONFIG_ARMV7_PSCI_NR_CPUS stacks, each 1 KB. There's also
__secure_stack_start and __secure_stack_end symbols. The linker script
handles calculating the correct VMAs for the stack section. For
platforms that relocate/copy the secure monitor before using it, the
space is not allocated in the executable, saving space.

For platforms that do not define CONFIG_ARMV7_PSCI_NR_CPUS, a whole page
of stack space for 4 CPUs is allocated, matching the previous behavior.
