powerpc: Remove arch/ppc and include/asm-ppc
All the maintained platforms are now in arch/powerpc, so the old arch/ppc stuff can now go away.

87 There are four types of PowerPC chips supported. The more common
88 types (601, 603, 604, 740, 750, 7400), the older Freescale
89 (formerly Motorola) embedded versions (821, 823, 850, 855, 860,
90 52xx, 82xx), the IBM embedded versions (403 and 405) and
91 the Book E embedded processors from IBM (44x) and Freescale (85xx).
92 For support for 64-bit processors, set ARCH=powerpc.
93 Unless you are building a kernel for one of the embedded processor
94 systems, choose 6xx.
95 Also note that because the 52xx, 82xx family have a 603e

143 ---help---
144 This option enables kernel support for the Altivec extensions to the
145 PowerPC processor. The kernel currently supports saving and restoring
146 altivec registers, and turning on the 'altivec enable' bit so user
147 processes can execute altivec instructions.
148
149 This option is only usefully if you have a processor that supports
150 altivec (G4, otherwise known as 74xx series), but does not have
151 any affect on a non-altivec cpu (it does, however add code to the
152 kernel).
153
154 If in doubt, say Y here.
155
156config TAU
157 bool "Thermal Management Support"
158 depends on 6xx && !8260
159 help
160 G3 and G4 processors have an on-chip temperature sensor called the
161 'Thermal Assist Unit (TAU)', which, in theory, can measure the on-die
162 temperature within 2-4 degrees Celsius. This option shows the current
163 on-die temperature in /proc/cpuinfo if the cpu supports it.
164
165 Unfortunately, on some chip revisions, this sensor is very inaccurate
166 and in some cases, does not work at all, so don't assume the cpu
167 temp is actually what /proc/cpuinfo says it is.
168
169config TAU_INT
170 bool "Interrupt driven TAU driver (DANGEROUS)"
171 depends on TAU
172 ---help---
173 The TAU supports an interrupt driven mode which causes an interrupt
174 whenever the temperature goes out of range. This is the fastest way
175 to get notified the temp has exceeded a range. With this option off,
176 a timer is used to re-check the temperature periodically.
177
178 However, on some cpus it appears that the TAU interrupt hardware
179 is buggy and can cause a situation which would lead unexplained hard
180 lockups.
181
182 Unless you are extending the TAU driver, or enjoy kernel/hardware
183 debugging, leave this option off.
184
185config TAU_AVERAGE
186 bool "Average high and low temp"
187 depends on TAU
188 ---help---
189 The TAU hardware can compare the temperature to an upper and lower
190 bound. The default behavior is to show both the upper and lower
191 bound in /proc/cpuinfo. If the range is large, the temperature is
192 either changing a lot, or the TAU hardware is broken (likely on some
193 G4's). If the range is small (around 4 degrees), the temperature is
194 relatively stable. If you say Y here, a single temperature value,
195 halfway between the upper and lower bounds, will be reported in
196 /proc/cpuinfo.
197
198 If in doubt, say N here.
199
200config MATH_EMULATION
201 bool "Math emulation"
202 depends on 4xx || 8xx
203 ---help---
204 Some PowerPC chips designed for embedded applications do not have
205 a floating-point unit and therefore do not implement the
206 floating-point instructions in the PowerPC instruction set. If you
207 say Y here, the kernel will include code to emulate a floating-point
208 unit, which will allow programs that use floating-point
209 instructions to run.
210
211 If you have an Apple machine or an IBM RS/6000 or pSeries machine,
212 or any machine with a 6xx, 7xx or 7xxx series processor, say N
213 here. Saying Y here will not hurt performance (on any machine) but
214 will increase the size of the kernel.
215
216config KEXEC
217 bool "kexec system call (EXPERIMENTAL)"
218 depends on EXPERIMENTAL
219 help
220 kexec is a system call that implements the ability to shutdown your
221 current kernel, and to start another kernel. It is like a reboot
222 but it is independent of the system firmware. And like a reboot
223 you can start any kernel with it, not just Linux.
224
225 The name comes from the similarity to the exec system call.
226
227 It is an ongoing process to be certain the hardware in a machine
228 is properly shutdown, so do not be surprised if this code does not
229 initially work for you. It may help to enable device hotplugging
230 support. As of this writing the exact hardware interface is
231 strongly in flux, so no good recommendation can be made.
232
233 In the GameCube implementation, kexec allows you to load and
234 run DOL files, including kernel and homebrew DOLs.

239 bool "Workarounds for PPC601 bugs"
240 depends on 6xx && PPC_PREP
241 help
242 Some versions of the PPC601 (the first PowerPC chip) have bugs which
243 mean that extra synchronization instructions are required near
244 certain instructions, typically those that make major changes to the
245 CPU state. These extra instructions reduce performance slightly.
246 If you say N here, these extra instructions will not be included,
247 resulting in a kernel which will run faster but may not run at all
248 on some systems with the PPC601 chip.
