MISRA rule 16.3 states all switch clause to have break statement.
Fixing the missing break statement for default case.
Two consecutive labels without statement need not have break.
So no break is added for case without any statement.
This also makes the switch statement well-formed covering 16.1.

The BIOS_GET_FIELD() macro does a simple bit mask and shift operation.
The value of this macro is assigned to variables of different data
types. Casting the macro to different data types causes MISRA rule
10.8 violations. This issue is resolved by doing the cast inside the
macro and returning the value in the correct data type. These changes
also clear MISRA rule 10.1, 10.3 and 10.4 violations.

To circumvent this issue we've introduced a new MISRA-compliant

dealing with microcontroller boot into chip specific files.
As most of the parsing is generic, they do not need to be called via

calls.
