+ * Abstract bitfield class
+ *
+ * Allows endianness-independent access to individual bitfields within some raw
+ * integer value. The assembly generated by this class is identical to the
+ * usage of raw bitfields, so it's a perfectly fine replacement.
+ *
+ * For BitField<X,Y,Z>, X is the distance of the bitfield to the LSB of the
+ * raw value, Y is the length in bits of the bitfield. Z is an integer type
+ * which determines the sign of the bitfield. Z must have the same size as the
+ * raw integer.
+ *
+ *
+ * General usage:
+ *
+ * Create a new union with the raw integer value as a member.
+ * Then for each bitfield you want to expose, add a BitField member
+ * in the union. The template parameters are the bit offset and the number
+ * of desired bits.
+ *
+ * Changes in the bitfield members will then get reflected in the raw integer
+ * value and vice-versa.
+ *
+ *
+ * Sample usage:
+ *
+ * union SomeRegister
+ * {
+ *     u32 hex;
+ *
+ *     BitField<0,7,u32> first_seven_bits;     // unsigned
+ *     BitField<7,8,32> next_eight_bits;       // unsigned
+ *     BitField<3,15,s32> some_signed_fields;  // signed
+ * };
+ *
+ * This is equivalent to the little-endian specific code:
+ *
+ * union SomeRegister
+ * {
+ *     u32 hex;
+ *
+ *     struct
+ *     {
+ *         u32 first_seven_bits : 7;
+ *         u32 next_eight_bits : 8;
+ *     };
+ *     struct
+ *     {
+ *         u32 : 3; // padding
+ *         s32 some_signed_fields : 15;
+ *     };
+ * };
+ *
+ *
+ * Caveats:
+ *
+ * 1)
+ * BitField provides automatic casting from and to the storage type where
+ * appropriate. However, when using non-typesafe functions like printf, an
+ * explicit cast must be performed on the BitField object to make sure it gets
+ * passed correctly, e.g.:
+ * printf("Value: %d", (s32)some_register.some_signed_fields);
+ *
+ * 2)
+ * Not really a caveat, but potentially irritating: This class is used in some
+ * packed structures that do not guarantee proper alignment. Therefore we have
+ * to use #pragma pack here not to pack the members of the class, but instead
+ * to break GCC's assumption that the members of the class are aligned on
+ * sizeof(StorageType).
+ * TODO(neobrain): Confirm that this is a proper fix and not just masking
+ * symptoms.
