      SDEI: Unconditionally resume Secure if it was interrupted · 90a9213b
      Jeenu Viswambharan authored 
      

Secure world execution nearly always expect a controlled exit to
Non-secure world. SDEI interrupts, although targets EL3, occur on behalf
of Non-secure world, and may have higher priority than Secure world
interrupts. Therefore they might preempt Secure execution, and yield
execution to Non-secure SDEI handler. Upon completion of SDEI event
handling (regardless of whether it's COPLETE or COMPLETE_AND_RESUME), we
must resume Secure execution if it was preempted.

      SPM: Raise running priority of the core while in Secure Partition · 6e3bad36
      Sughosh Ganu authored 
      

The current secure partition design mandates that a) at a point, only
a single core can be executing in the secure partition, and b) a core
cannot be preempted by an interrupt while executing in secure
partition.

Ensure this by activating the SPM priority prior to entering the
parition. Deactivate the priority on return from the
partition.

      Standardise header guards across codebase · c3cf06f1
      Antonio Nino Diaz authored 
      

All identifiers, regardless of use, that start with two underscores are
reserved. This means they can't be used in header guards.

The style that this project is now to use the full name of the file in
capital letters followed by 'H'. For example, for a file called
"uart_example.h", the header guard is UART_EXAMPLE_H.

The exceptions are files that are imported from other projects:

- CryptoCell driver
- dt-bindings folders
- zlib headers

      Ensure the flow through switch statements is clear · a08a2014
      Daniel Boulby authored 
      

Ensure case clauses:
*   Terminate with an unconditional break, return or goto statement.
*   Use conditional break, return or goto statements as long as the end
    of the case clause is unreachable; such case clauses must terminate
    with assert(0) /* Unreachable */ or an unconditional  __dead2 function
    call
*   Only fallthough when doing otherwise would result in less
    readable/maintainable code; such case clauses must terminate with a
    /* Fallthrough */ comment to make it clear this is the case and
    indicate that a fallthrough is intended.

This reduces the chance of bugs appearing due to unintended flow through a
switch statement
