For STM32MP1, the address space is 4GB, which can be first divided
in 4 parts of 1GB. This LVL1 table is already mapped regardless
of MAX_XLAT_TABLES.
Fixing typo: Replace Ko to KB.

BL2/sp_min for platform STM32MP1 requires 4 MMU translation tables:
  - a level2 table and a level3 table for identity mapped SYSRAM
  - a level2 table mapping 2MB of BootROM runtime resources
  - a level2 table mapping 2MB of secure DDR (case BL32 is OP-TEE)

SPI-NOR framework is based on SPI-MEM framework using
spi_mem_op execution interface.

It implements read functions and allows NOR configuration
up to quad mode.
Default management is 1 data line but it can be overridden
by platform.
It also includes specific quad mode configuration for
Spansion, Micron and Macronix memories.

This framework supports SPI-NAND and is based on the
SPI-MEM framework for SPI operations. It uses a common high
level access using the io_mtd.

It is limited to the read functionalities.

Default behavior is the basic one data line operation
but it could be overridden by platform.

The raw NAND framework supports SLC NAND devices.

It introduces a new high level interface (io_mtd) that
defines operations a driver can register to the NAND framework.
This interface will fill in the io_mtd device specification:
	- device_size
        - erase_size
that could be used by the io_storage interface.

NAND core source file integrates the standard read loop that
performs NAND device read operations using a skip bad block strategy.
A platform buffer must be defined in case of unaligned
data. This buffer must fit to the maximum device page size
defined by PLATFORM_MTD_MAX_PAGE_SIZE.

The raw_nand.c source file embeds the specific NAND operations
to read data.
The read command is a raw page read without any ECC correction.
This can be overridden by a low level driver.
No generic support for write or erase command or software
ECC correction.

NAND ONFI detection is available and can be enabled using
NAND_ONFI_DETECT=1.
For non-ONFI NAND management, platform can define required
information.

This patch implements a handler to enter the standby state on
Tegra194 platforms. On receiving a CPU_STANDBY state request,
the platform handler issues TEGRA_NVG_CORE_C6 request to the
MCE firmware to take the CPU into the standby state.

Force memory transactions from viw and viflar/w as non-coherent from
no-override. This is necessary as iso clients shouldn't use coherent
path and stage-2 smmu mappings won't mark transactions as non-coherent.
For native case, no-override works. But, not for virtualization case.

Client order id reset values are incorrectly and'ed with

as necessary.

This patch adds support for shutdown/reboot handlers to the MCE
driver.

ATF communicates with mce using nvg interface for shutdown &
reboot. Both shutdown and reboot use the same nvg index.
However, the 1st bit of the nvg data argument differentiates
whether its a shutdown or reboot.
