153 bool "Support for memory management hardware"
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.
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.
165 bool "Support 32-bit physical addressing through PMB"
169 If you say Y here, physical addressing will be extended to
170 32-bits through the SH-4A PMB. If this is not set, legacy
171 29-bit physical addressing will be used.

197 config SH_DIRECT_MAPPED
198 bool "Use direct-mapped caching"
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.)
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.
209 config SH_WRITETHROUGH
210 bool "Use write-through caching"
213 Selecting this option will configure the caches in write-through
214 mode, as opposed to the default write-back configuration.
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.
223 bool "Operand Cache RAM (OCRAM) support"
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.
228 The addresses for the OC RAM base will vary according to the
229 processor version. Consult vendor documentation for specifics.
