Remove the fancy RegisterSet class introduced in 4c2bff61e
.
While it was some nice and fancy template usage, it ultimately had many practical issues regarding length of involved expressions under regular usage as well as common code completion tools not being able to handle the structures. Instead, we now use a more conventional approach which is a lot more clean to use.

/*
|
||||
* Standardized way to define a group of registers and corresponding data structures. To define
|
||||
* a new register set, first define struct containing an enumeration called "Id" containing
|
||||
* all register IDs and a template struct called "Struct". Specialize the Struct struct for any
|
||||
* register ID which needs to be accessed in a specialized way. You can then declare the object
|
||||
* containing all register values using the RegisterSet<BaseType, DefiningStruct> type, where
|
||||
* BaseType is the underlying type of each register (e.g. u32).
|
||||
* Of course, you'll usually want to implement the Struct template such that they are of the same
|
||||
* size as BaseType. However, it's also possible to make it larger, e.g. when you want to describe
|
||||
* multiple registers with the same structure.
|
||||
*
|
||||
* Example:
|
||||
*
|
||||
* struct Regs {
|
||||
* enum Id : u32 {
|
||||
* Value1 = 0,
|
||||
* Value2 = 1,
|
||||
* Value3 = 2,
|
||||
* NumIds = 3
|
||||
* };
|
||||
*
|
||||
* // declare register definition structures
|
||||
* template<Id id>
|
||||
* struct Struct;
|
||||
* };
|
||||
*
|
||||
* // Define register set object
|
||||
* RegisterSet<u32, CommandIds> registers;
|
||||
*
|
||||
* // define register definition structures
|
||||
* template<>
|
||||
* struct Regs::Struct<Regs::Value1> {
|
||||
* union {
|
||||
* BitField<0, 4, u32> some_field;
|
||||
* BitField<4, 3, u32> some_other_field;
|
||||
* };
|
||||
* };
|
||||
*
|
||||
* Usage in external code (within SomeNamespace scope):
|
||||
*
|
||||
* For a register which maps to a single index:
|
||||
* registers.Get<Regs::Value1>().some_field = some_value;
|
||||
*
|
||||
* For a register which maps to different indices, e.g. a group of similar registers
|
||||
* registers.Get<Regs::Value1>(index).some_field = some_value;
|
||||
*
|
||||
*
|
||||
* @tparam BaseType Base type used for storing individual registers, e.g. u32
|
||||
* @tparam RegDefinition Class defining an enumeration called "Id" and a template<Id id> struct, as described above.
|
||||
* @note RegDefinition::Id needs to have an enum value called NumIds defining the number of registers to be allocated.
