 12	  This option enables support for the Sony PS3 game console
 13	  and other platforms using the PS3 hypervisor.  Enabling this
 14	  option will allow building otheros.bld, a kernel image suitable
 15	  for programming into flash memory, and vmlinux, a kernel image
 16	  suitable for loading via kexec.

 23	bool "PS3 Advanced configuration options"
 24	help
 25	  This gives you access to some advanced options for the PS3. The
 26	  defaults should be fine for most users, but these options may make
 27	  it possible to better control the kernel configuration if you know
 28	  what you are doing.
 29
 30	  Note that the answer to this question won't directly affect the
 31	  kernel: saying N will just cause the configurator to skip all
 32	  the questions about these options.
 33
 34	  Most users should say N to this question.

 41	help
 42	  This option is only for experts who may have the desire to fine
 43	  tune the pagetable size on their system.  The value here is
 44	  expressed as the log2 of the page table size.  Valid values are
 45	  18, 19, and 20, corresponding to 256KB, 512KB and 1MB respectively.
 46

 53	help
 54	  This option will enable kernel support to take advantage of the
 55	  per device dynamic DMA page table management provided by the Cell
 56	  processor's IO Controller.  This support incurs some runtime
 57	  overhead and also slightly increases kernel memory usage.  The
 58	  current implementation should be considered experimental.
 59
 60	  This support is mainly for Linux kernel development.  If unsure,
 61	  say N.

104
105	  This support is intended for bootloaders that need to store data
106	  in the repository for later boot stages.
