Hikey960: Change CPU standby state for WFI
At early time, the CPU CA73 retention state has been supported on
Hikey960. Later we found the system has the hang issue and for
resolving this issue Hisilicon released new MCU firmware, but
unfortunately the new MCU firmware has side effect and results in the
CA73 CPU cannot really enter retention state and roll back to WFI state.
After discussion we cannot see the possibility to enable CA73 retention
state anymore on Hikey960, based on this conclusion we should remove
this state supporting from ARM-TF and roll back to WFI state only. We
will commit one patch to remove CA73 CPU retention state in kernel DT
binding as well.

The commit
fdae60b6ba27c216fd86d13b7432a1ff4f57dd84 changed the
parameter encoding for the hikey960. However that implies a DT change
in the kernel side. After submitting the DT change for upstreaming,
the backward compatibility issue and the interface change raise some
concerns from the Linux community about the issues related to kernel <->
ATF alignment. There is no way to detect a mis-alignment of those
without a deep knowledge of the ATF and the kernel. Furthermore, the
failing calls to PSCI in the idle path (because of bad parameters), will
lead to busy looping, implying: thermal issues and extra energy
consumption.
In regard of the Linux community concerns, the potential issues when the
ATF and the kernel are not aligned, it is preferable to revert the
commit.

Workaround for CVE-2017-5715 on Cortex A73 and A75
Invalidate the Branch Target Buffer (BTB) on entry to EL3 by
temporarily dropping into AArch32 Secure-EL1 and executing the
`BPIALL` instruction.
This is achieved by using 3 vector tables. There is the runtime
vector table which is used to handle exceptions and 2 additional
tables which are required to implement this workaround. The
additional tables are `vbar0` and `vbar1`.
The sequence of events for handling a single exception is
as follows:
1) Install vector table `vbar0` which saves the CPU context on entry
to EL3 and sets up the Secure-EL1 context to execute in AArch32 mode
with the MMU disabled and I$ enabled. This is the default vector table.
2) Before doing an ERET into Secure-EL1, switch vbar to point to
another vector table `vbar1`. This is required to restore EL3 state
when returning from the workaround, before proceeding with normal EL3
exception handling.
3) While in Secure-EL1, the `BPIALL` instruction is executed and an
SMC call back to EL3 is performed.
4) On entry to EL3 from Secure-EL1, the saved context from step 1) is
restored. The vbar is switched to point to `vbar0` in preparation to
handle further exceptions. Finally a branch to the runtime vector
table entry is taken to complete the handling of the original
exception.
This workaround is enabled by default on the affected CPUs.
NOTE
====
There are 4 different stubs in Secure-EL1. Each stub corresponds to
an exception type such as Sync/IRQ/FIQ/SError. Each stub will move a
different value in `R0` before doing an SMC call back into EL3.
Without this piece of information it would not be possible to know
what the original exception type was as we cannot use `ESR_EL3` to
distinguish between IRQs and FIQs.

and then branches off to the corresponding vector entry in the main

We control IPI agents registers access but not IPI buffers access in

The Secure Partition should be able to be used from any CPU, not just

In order to prevent more than one CPU from using the Secure Partition at

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.

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

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