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
