Allow BL3-2 to be loaded into the secure region of DRAM

Soby Mathew ab8707e687 Remove coherent memory from the BL memory maps
This patch extends the build option `USE_COHERENT_MEMORY` to
conditionally remove coherent memory from the memory maps of
all boot loader stages. The patch also adds necessary
documentation for coherent memory removal in firmware-design,
porting and user guides.

Fixes ARM-Software/tf-issues#106

Juan Castillo 6fd9eaf36e FVP: map non-secure DRAM1 in the MMU
This patch maps the non-secure region of DRAM1 in the MMU. The
non-secure region comprises the whole DRAM1 (0x80000000 -
0xffffffff) excluding the top 16 MB (0xff000000 - 0xffffffff).
The TrustZone controller configures this 16 MB region as secure
memory, so it can not be accessed in non-secure mode.

The number of MMU tables in BL2 has been increased to 3 because
the new size of the non-secure region in DRAM requires an extra L2
table.

Juan Castillo 20d51cad8b FVP: keep shared data in Trusted SRAM
This patch deprecates the build option to relocate the shared data
into Trusted DRAM in FVP. After this change, shared data is always
located at the base of Trusted SRAM. This reduces the complexity
of the memory map and the number of combinations in the build
options.

Fixes ARM-software/tf-issues#257

Juan Castillo 186c1d4b26 FVP: make usage of Trusted DRAM optional at build time
This patch groups the current contents of the Trusted DRAM region at
address 0x00_0600_0000 (entrypoint mailboxes and BL3-1 parameters) in
a single shared memory area that may be allocated to Trusted SRAM
(default) or Trusted DRAM at build time by setting the
FVP_SHARED_DATA_LOCATION make variable. The size of this shared
memory is 4096 bytes.

The combination 'Shared data in Trusted SRAM + TSP in Trusted DRAM'
is not currently supported due to restrictions in the maximum number
of mmu tables that can be created.

Documentation has been updated to reflect these changes.

Juan Castillo 637ebd2eb9 FVP: apply new naming conventions to memory regions
Secure ROM at address 0x0000_0000 is defined as FVP_TRUSTED_ROM
Secure RAM at address 0x0400_0000 is defined as FVP_TRUSTED_SRAM
Secure RAM at address 0x0600_0000 is defined as FVP_TRUSTED_DRAM

BLn_BASE and BLn_LIMIT definitions have been updated and are based on
these new memory regions.

The available memory for each bootloader in the linker script is
defined by BLn_BASE and BLn_LIMIT, instead of the complete memory
region.

TZROM_BASE/SIZE and TZRAM_BASE/SIZE are no longer required as part of
the platform porting.

FVP common definitions are defined in fvp_def.h while platform_def.h
contains exclusively (with a few exceptions) the definitions that are
mandatory in the porting guide. Therefore, platform_def.h now includes
fvp_def.h instead of the other way around.

Porting guide has been updated to reflect these changes.

Soby Mathew 462c8350f6 Parametrize baudrate and UART clock during console_init()
This patch adds baud rate and UART clock frequency as parameters
to the pl011 driver api console_init(). This allows each platform
to specify UART clock and baud rate according to their specific
hardware implementation.

Sandrine Bailleux 8f55dfb4ba Remove concept of top/bottom image loading
This concept is no longer required since we now support loading of
images at fixed addresses only.

The image loader now automatically detects the position of the image
inside the current memory layout and updates the layout such that
memory fragmentation is minimised.

The 'attr' field of the meminfo data structure, which used to hold
the bottom/top loading information, has been removed. Also the 'next'
field has been removed as it wasn't used anywhere.

The 'init_bl2_mem_layout()' function has been moved out of common
code and put in BL1-specific code. It has also been renamed into
'bl1_init_bl2_mem_layout'.

This patch reworks FVP specific code responsible for determining
the entry point information for BL3-2 and BL3-3 stages when BL3-1
is configured as the reset handler.

Andrew Thoelke 0346267194 Allow platform parameter X1 to be passed to BL3-1
bl2_main() was overwriting any platform set X1 parameter for BL3-1
with the value zero.

This patch ensure that any platform set value is correctly passed
to BL3-1. The FVP port adds a check to verify this parameter is
being passed correctly.

FVP specific files and functions containing the word "plat" have been
renamed to use the word "fvp" to distinguish them from the common
platform functionality and porting functions.
