181  *
182  * The goal of these types is to provide source code portability across
183  * 16-bit, 32-bit, and 64-bit targets.
184  *
185  * 1) The following types are of fixed size for all targets (16/32/64):
186  *
187  * BOOLEAN      Logical boolean
188  *
189  * UINT8        8-bit  (1 byte) unsigned value
190  * UINT16       16-bit (2 byte) unsigned value
191  * UINT32       32-bit (4 byte) unsigned value
192  * UINT64       64-bit (8 byte) unsigned value
193  *
194  * INT16        16-bit (2 byte) signed value
195  * INT32        32-bit (4 byte) signed value
196  * INT64        64-bit (8 byte) signed value
197  *
198  * COMPILER_DEPENDENT_UINT64/INT64 - These types are defined in the
199  * compiler-dependent header(s) and were introduced because there is no
200  * common 64-bit integer type across the various compilation models, as
201  * shown in the table below.
202  *
203  * Datatype  LP64 ILP64 LLP64 ILP32 LP32 16bit
204  * char      8    8     8     8     8    8
205  * short     16   16    16    16    16   16
206  * _int32         32
207  * int       32   64    32    32    16   16
208  * long      64   64    32    32    32   32
209  * long long            64    64
210  * pointer   64   64    64    32    32   32
211  *
212  * Note: ILP64 and LP32 are currently not supported.
213  *
214  *
215  * 2) These types represent the native word size of the target mode of the
216  * processor, and may be 16-bit, 32-bit, or 64-bit as required. They are
217  * usually used for memory allocation, efficient loop counters, and array
218  * indexes. The types are similar to the size_t type in the C library and
219  * are required because there is no C type that consistently represents the
220  * native data width. ACPI_SIZE is needed because there is no guarantee
221  * that a kernel-level C library is present.
222  *
223  * ACPI_SIZE        16/32/64-bit unsigned value
224  * ACPI_NATIVE_INT  16/32/64-bit signed value
