io: Allow image load to address zero
...
Remove assert on buffer address equal zero.
Marvell uses address 0x0 for loading BL33,
so this check is irrelevant and breaks the
debug builds on Marvell platforms.

Extend FIP io driver to support multiple FIP devices
...
Platform can define MAX_NUM_FIP_DEVICES in platform_def.h
to define the number of FIP io devices.
The FIP driver doesn't support muliple open file.
So only one single file can be open at a time across
multiple FIP devices.
For any FIP device, an image should be loaded
fully before moving on to the next image.

Make TF UUID RFC 4122 compliant

RFC4122 defines that fields are stored in network order (big endian),
but TF-A stores them in machine order (little endian by default in TF-A).
We cannot change the future UUIDs that are already generated, but we can store
all the bytes using arrays and modify fiptool to generate the UUIDs with
the correct byte order.

Remove URLs from comments
...
This fixes all defects according to MISRA Rule 3.1: "The character
sequences /* and // shall not be used within a comment". This affects
all URLs in comments, so they have been removed:
- The link in `sdei_state.c` can also be found in the documentation file
`docs/sdei.rst`.
- The bug that the file `io_fip.c` talks about doesn't affect the
currently supported version of GCC, so it doesn't make sense to keep
the comment. Note that the version of GCC officially supported is the
one that comes with Linaro Release 17.10, which is GCC 6.2.
- The link in `tzc400.c` was broken, and it didn't correctly direct to
the Technical Reference Manual it should. The link has been replaced
by the title of the document, which is more convenient when looking
for the document.

io: block: fix block_read/write may read/write overlap buffer
...
The block operations were trying to optimize the number of memory
copies, and it tried to use directly the buffer supplied by the user
to them. This was a mistake because it created too many corner cases:
1- It was possible to generate unaligned
operations to unaligned buffers. Drivers that were using
DMA transfer failed in that case.
2- It was possible to generate read operations
with sizes that weren't a multiple of the block size. Some
low level drivers assumed that condition and they calculated
the number of blocks dividing the number of bytes by the
size of the block, without considering the remaining bytes.
3- The block_* operations didn't control the
number of bytes actually copied to memory, because the
low level drivers were writing directly to the user buffer.
This patch rewrite block_read and block_write to use always the device
buffer, which the platform ensures that has the correct aligment and
the correct size.

asserts that:
- non-negative size is specified for for backing memory;
- valid parameters are passed into the driver for read, write and seek
operations.

Replace some memset call by zeromem
...
Replace all use of memset by zeromem when zeroing moderately-sized
structure by applying the following transformation:
memset(x, 0, sizeof(x)) => zeromem(x, sizeof(x))
As the Trusted Firmware is compiled with -ffreestanding, it forbids the
compiler from using __builtin_memset and forces it to generate calls to
the slow memset implementation. Zeromem is a near drop in replacement
for this use case, with a more efficient implementation on both AArch32
and AArch64.

IO: support block device type
...
FIP is accessed as memory-mapped type. eMMC is block device type.
In order to support FIP based on eMMC, add the new io_block layer.
io_block always access eMMC device as block size. And it'll only
copy the required data into buffer in io_block driver. So preparing
an temporary buffer is required.
When use io_block device, MAX_IO_BLOCK_DEVICES should be declared
in platform_def.h. It's used to support multiple block devices.

Use numbers to identify images instead of names
...
The Trusted firmware code identifies BL images by name. The platform
port defines a name for each image e.g. the IO framework uses this
mechanism in the platform function plat_get_image_source(). For
a given image name, it returns the handle to the image file which
involves comparing images names. In addition, if the image is
packaged in a FIP, a name comparison is required to find the UUID
for the image. This method is not optimal.
This patch changes the interface between the generic and platform
code with regard to identifying images. The platform port must now
allocate a unique number (ID) for every image. The generic code will
use the image ID instead of the name to access its attributes.
As a result, the plat_get_image_source() function now takes an image
ID as an input parameter. The organisation of data structures within
the IO framework has been rationalised to use an image ID as an index
into an array which contains attributes of the image such as UUID and
name. This prevents the name comparisons.
A new type 'io_uuid_spec_t' has been introduced in the IO framework
to specify images identified by UUID (i.e. when the image is contained
in a FIP file). There is no longer need to maintain a look-up table
[iname_name --> uuid] in the io_fip driver code.
Because image names are no longer mandatory in the platform port, the
debug messages in the generic code will show the image identifier
instead of the file name. The platforms that support semihosting to
load images (i.e. FVP) must provide the file names as definitions
private to the platform.
The ARM platform ports and documentation have been updated accordingly.
All ARM platforms reuse the image IDs defined in the platform common
code. These IDs will be used to access other attributes of an image in
subsequent patches.
IMPORTANT: applying this patch breaks compatibility for platforms that
use TF BL1 or BL2 images or the image loading code. The platform port
must be updated to match the new interface.
