This reverts commit 76d84cbc.

Change-Id: I867af7af3d9f5e568101f79b9ebea578e5cb2a4b

Since BL31 PROGBITS and BL31 NOBITS sections are going to be
in non-adjacent memory regions, potentially far from each other,
some fixes are needed to support it completely.

1. adr instruction only allows computing the effective address
of a location only within 1MB range of the PC. However, adrp
instruction together with an add permits position independent
address of any location with 4GB range of PC.

2. Since BL31 _RW_END_ marks the end of BL31 image, care must be
taken that it is aligned to page size since we map this memory
region in BL31 using xlat_v2 lib utils which mandate alignment of
image size to page granularity.

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.

This framework supports SPI operations using a common
spi_mem_op structure:
 - command
 - addr
 - dummy
 - data

The framework manages SPI bus configuration:
 - speed
 - bus width (Up to quad mode)
 - chip select

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.

The LLVM linker replaces the GNU linker as default for the link on Clang
