Some parameters from BootROM boot context can be required after boot.
To save space in SYSRAM, this context can be overwritten during images
load sequence. The needed information (here the boot interface) is
then saved in a local variable.

Avoid parsing device tree every time when returning
the DDR size.
A cache flush on this size is also added because TZC400 configuration
is applied at the end of BL2 after MMU and data cache being turned off.
Configuration needs to retrieve the DDR size to generate the correct
region. Access to the size fails because the value is still in the data
cache. Flushing the size is mandatory.

In BL2, the DDR can be mapped as secured in MMU, as no other SW
has access to it during its execution.
The TZC400 configuration is also updated to reflect this. When using
OP-TEE, the TZC400 is reconfigured at the end of BL2, to match OP-TEE
mapping. Else, SP_min will be in charge to reconfigure TZC400 to set
DDR non-secure.

All API calls except non-blocking should wait for

status from IPI payload data. Use sync method which
reads actual return status from IPI payload.

 - In tpm_record_measurement():

   The platform layer is responsible for providing an exhaustive list
   of images to measure. If it doesn't then this should be treated as
   a programming error, as documented in [1].

   Thus, turn the error test into an assertion.

- In add_event2():

  Turn the first error condition checking whether there is room for an
  extra event2 data structure into an assertion. The platform layer is
  responsible for choosing an appropriate event log buffer size based
  on the number of measurements it expects. If this assertion fires,
  the platform macro EVENT_LOG_SIZE should be adjusted and the
  firmware recompiled.

  Call this assumption out in the function documentation.

  Also remove the second error condition check, which is a subset of
  the first one and thus is redundant.

  As a result of these changes, add_event2() can no longer fail. Thus,
  change its return type from int to void.

  Also, the 'size_of_event' local variable is now unused in release
  builds so remove it and move its value into the assertion.

 - In event_log_init():

   Throughout the function, we are incrementing a pointer by some fixed
   amounts of bytes (corresponding to the size of some data structure or
   to some constant number of bytes), there is no variable-size
   increments in the picture. Thus it seems pointless to verify that the
   pointer has indeed been incremented by this fixed amount of bytes
   afterwards.

   For this reason, remove these checks altogether. As a result, the
   start_ptr local variable is now unused so remove it as well.

In mt8195 suspend/resume flow, ATF has to communicate with a subsys by
read/write the subsys registers. However, the register region of subsys
doesn't include in the MMU mapping region. It triggers MMU faults.

This patch extends the MMU region 0 size to cover all mt8195 HW modules.
This patch also remove MMU region 1 because region 0 covers region 1.

Merge "refactor(measured boot): remove weak definition of plat_get_measured_boot_data()" into integration

Weak definitions are confusing and should be avoided if possible.
Thus, turn plat_get_measured_boot_data() into a strong definition that
platforms must provide (if they need measured boot).

We could have moved the old weak implementation under plat/common as a
sane, default implementation that platforms may pull in if it suits
them. However, this implementation right now simply measures BL2,
which is not enough to get a complete measured boot flow, so this
patch just removes it.

This change only affects the Arm FVP platform, as no other upstream
platform implements measured boot at the moment.
