Add padding at the end of the last entry ...

This patch adds padding bytes at the end of the last image in the
fip to be able to transfer by DMA the last image.

doc: uniphier: reformat reStructuredText manually ...

Commit 6f6257476754 ("Convert documentation to reStructuredText")
automatically converted all documents by a tool.  I see some parts
were converted in an ugly way (or, at least, it is not my intention).
Also, the footnote is apparently broken.

I checked this document by my eyes, and reformated it so that it looks
nicer both in plain text and reST form.

Disable PIE compilation option ...

ARM TF does not work correctly if built with a version of gcc
that is configured to use PIE by default (e.g. Debian Stretch).

This patch identifies when such a version of gcc is being used
(by searching for --enable-default-pie) and adds -fno-PIE option
to TF_CFLAGS.

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.

SPM: Fix MM_COMMUNICATE_AARCH32/64 parameters ...

This partially reverts commit d6b532b50f8, keeping only the fixes to
the assertions. The changes related to the order of arguments passed
to the secure partition were not correct and violated the
specification of the SP_EVENT_COMPLETE SMC.

This patch also improves the MM_COMMUNICATE argument validation.  The
cookie argument, as it comes from normal world, can't be trusted and thus
needs to always be validated at run time rather than using an assertion.

Also validate the communication buffer address and return
INVALID_PARAMETER if it is zero, as per the MM specification.

Fix a few typos in comments and use the "secure partition" terminology
rather than "secure payload".
