Steven Cartmell e0d98bfe2c Adapt MbedCRC class to support Hardware CRC 
- Move CRC polynomial enum into HAL layer, so it's accessible from platform
  implementations

- Add enum to CRC class to indicate which mode the CRC class should use:
  HARDWARE, TABLE, or BITWISE

- Add calls to HAL Hardware CRC API to each of the compute functions when the
  class is in HARDWARE mode.

- Add missing constructor call to template constructor, and remove const from
  delegating constructor.

Deepika 331620e1d0 Default constructor for template class should be part of header file 2018-03-23 14:55:07 -05:00
deepikabhavnani b60eb1d001 Updated table to be const and small fixes 2018-02-27 09:35:55 -06:00
deepikabhavnani af0982295f Moved specialized functions to CPP file 
Template specialized functions are moved to cpp file, to add MbedCRC.h
in mbed.h. Else linker shall multiple definition error.

deepikabhavnani afe8834bb8 CRC class implementation 
CRC class `MbedCRC.h` is templated class created to support hardware/software
CRCs. Default CRC will be hardware CRC when support for HAL is available.

Polynomial tables are available for 8/16 bit CCITT, 7/16 bit for SD card and
32-bit ANSI. Polynomial table implementation will be used if Hardware CRC is
not available.

In case device does not have hardware CRC and polynomial table is not supported,
CRC is still available and is computed runtime bit by bit for all data input.
