     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.

     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.

     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
     47	  If unsure, choose the default (20) with the confidence that your
     48	  system will have optimal runtime performance.

     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.

    102	  Enables support for writing to the PS3 System Repository.
    103
    104	  This support is intended for bootloaders that need to store data
    105	  in the repository for later boot stages.
    106
    107	  If in doubt, say N here and reduce the size of the kernel by a

    141
    142	  This support is required to access the PS3 FLASH ROM, which
    143	  contains the boot loader and some boot options.
    144	  In general, PS3 OtherOS users will say Y or M.
    145
    146	  As this driver needs a fixed buffer of 256 KiB of memory, it can
    147	  be disabled on the kernel command line using "ps3flash=off", to
