Rename drivers/console/console.c to
drivers/arm/peripherals/pl011/pl011_console.c. This makes it clear
that this is a pl011 specific console implementation.

Fixes ARM-software/tf-issues#129

Change-Id: Ie2f8109602134c5b86993e32452c70734c45a3ed

This patch reworks the console driver to ensure that each bootloader stage
initializes it independently. As a result, both BL3-1 and BL2 platform code
now calls console_init() instead of relying on BL1 to perform console setup

Fixes ARM-software/tf-issues#120

Change-Id: Ic4d66e0375e40a2fc7434afcabc8bbb4715c14ab

This commit isolates the accessor functions in pl011.c and builds
a wrapper layer for console functions.

This also modifies the console driver to use the pl011 FIFO.

This patch fixes a bug in the 'file_to_uuid()' function: it used
to cause an exception by dereferencing a null pointer when
a given UUID was not found in the UUID array. The fix is to delete
the final null entry in the UUID array, which is not needed because
the array is statically declared so its size is known at build time.

This patch changes all/most variables of type int to be size_t or long
to fix the sizing and alignment problems found when building with the
newer toolchains such as Linaro GCC 13.12 or later.

At present many recoverable failures are reported as errors. This patch
modifies all such failures to be reported as warnings instead.

If there is a request to open a file from FIP, and that file is not
found, the driver fails to reset the offset address. This causes
subsequent file loads to fail.

This patch resets the offset address to zero if a file is not found so
that subsequent file loads are unaffected.

This patch adds the ability to specify the base address of a UART
device for initialising the console. This allows a boot loader stage
to use a different UART device from UART0 (default) for the console.

The Firmware Image Package (FIP) driver allows for data to be loaded
from a FIP on platform storage. The FVP supports loading bootloader
images from a FIP located in NOR FLASH.

The implemented FVP policy states that bootloader images will be
loaded from a FIP in NOR FLASH if available and fall back to loading
individual images from semi-hosting.

NOTE:
- BL3-3(e.g. UEFI) is loaded into DRAM and needs to be configured
  to run from the BL33_BASE address. This is currently set to
  DRAM_BASE+128MB for the FVP.

The modified implementation uses the IO abstraction rather than
making direct semi-hosting calls.  The semi-hosting driver is now
registered for the FVP platform during initialisation of each boot
stage where it is used.  Additionally, the FVP platform includes a
straightforward implementation of 'plat_get_image_source' which
provides a generic means for the 'load_image' function to determine
how to access the image data.

This is intended primarily for use as a storage abstraction.
It allows operations such as image-loading to be implemented
in a platform-independent fashion.  Each platform registers
a set of IO drivers during initialisation.  The platform must
also provide a function that will return a device and a specifier
that can be used to access specified content.

Clients of the API will primarily use device and entity handles.
The term "entity" is deliberately vague, to allow for different
representations of content accessed using different types of
specifier, but will often be interpreted as a "file" where the
specifier will normally be its path.

This commit builds, but is intended to be paired with a sample
implementation of "load_image" using a semi-hosting driver on FVP.

The FVP specific code that gets called after a cpu has been physically
powered on after having been turned off or suspended earlier does not
clear the PWRC.PWKUPR.WEN bit. Not doing so causes problems if: a cpu
is suspended, woken from suspend, powered down through a cpu_off call
& receives a spurious interrupt. Since the WEN bit is not cleared
after the cpu woke up from suspend, the spurious wakeup will power the
cpu on. Since the cpu_off call clears the jump address in the mailbox
this spurious wakeup will cause the cpu to crash.

This patch fixes this issue by clearing the WEN bit whenever a cpu is
powered up.
