Steven Cartmell 04d2f3de78 Amend critical section function descriptions 2018-01-05 14:55:58 +00:00
Steven Cartmell a07c07fa63 Update HAL API header information 2018-01-05 14:55:57 +00:00
Steven Cartmell 07a394ee8b Add Critical Section HAL API specification 
- Define header functions for Critical Section HAL API
  - hal_critical_section_enter()
  - hal_critical_section_exit()

- Add weak default implementation for HAL API. The default implementation
  matches the previous behaviour stored in mbed_critical:
  - The first call to enter a critical section stores the state of interrupts
    before disabling and each successive call re-disables interrupts.
  - The last call (non-nested) will restore the IRQ state that was set on the
    enter to the critical section. Nested calls are ignored.

- Add function 'core_util_in_critical_section' to User facing API to determine
  if the program is currently in a critical section, instead of depending on
  'core_util_interrupts_enabled'.
