153 bool "Support for memory management hardware"

155 default y
156 help
157 Some SH processors (such as SH-2/SH-2A) lack an MMU. In order to
158 boot on these systems, this option must not be set.
159
160 On other systems (such as the SH-3 and 4) where an MMU exists,
161 turning this off will boot the kernel on these machines with the
162 MMU implicitly switched off.

170 32-bits through the SH-4A PMB. If this is not set, legacy

200 help
201 Selecting this option will configure the caches to be direct-mapped,
202 even if the cache supports a 2 or 4-way mode. This is useful primarily
203 for debugging on platforms with 2 and 4-way caches (SH7750R/SH7751R,
204 SH4-202, SH4-501, etc.)
205
206 Turn this option off for platforms that do not have a direct-mapped
207 cache, and you have no need to run the caches in such a configuration.

209config SH_WRITETHROUGH

212 help
213 Selecting this option will configure the caches in write-through
214 mode, as opposed to the default write-back configuration.
215
216 Since there's sill some aliasing issues on SH-4, this option will
217 unfortunately still require the majority of flushing functions to
218 be implemented to deal with aliasing.

225 Selecting this option will automatically tear down the number of
226 sets in the dcache by half, which in turn exposes a memory range.
227
228 The addresses for the OC RAM base will vary according to the
229 processor version. Consult vendor documentation for specifics.

231 If unsure, say N.
