- =======================================
- FUJITSU FR-V LINUX KERNEL CONFIGURATION
- =======================================
-
-=====================
-CONFIGURATION OPTIONS
-=====================
-
-The most important setting is in the "MMU support options" tab (the first
-presented in the configuration tools available):
-
- (*) "Kernel Type"
-
- This options allows selection of normal, MMU-requiring linux, and uClinux
- (which doesn't require an MMU and doesn't have inter-process protection).
-
-There are a number of settings in the "Processor type and features" section of
-the kernel configuration that need to be considered.
-
- (*) "CPU"
-
- The register and instruction sets at the core of the processor. This can
- only be set to "FR40x/45x/55x" at the moment - but this permits usage of
- the kernel with MB93091 CB10, CB11, CB30, CB41, CB60, CB70 and CB451
- CPU boards, and with the MB93093 PDK board.
-
- (*) "System"
-
- This option allows a choice of basic system. This governs the peripherals
- that are expected to be available.
-
- (*) "Motherboard"
-
- This specifies the type of motherboard being used, and the peripherals
- upon it. Currently only "MB93090-MB00" can be set here.
-
- (*) "Default cache-write mode"
-
- This controls the initial data cache write management mode. By default
- Write-Through is selected, but Write-Back (Copy-Back) can also be
- selected. This can be changed dynamically once the kernel is running (see
- features.txt).
-
-There are some architecture specific configuration options in the "General
-Setup" section of the kernel configuration too:
-
- (*) "Reserve memory uncached for (PCI) DMA"
-
- This requests that a uClinux kernel set aside some memory in an uncached
- window for the use as consistent DMA memory (mainly for PCI). At least a
- megabyte will be allocated in this way, possibly more. Any memory so
- reserved will not be available for normal allocations.
-
- (*) "Kernel support for ELF-FDPIC binaries"
-
- This enables the binary-format driver for the new FDPIC ELF binaries that
- this platform normally uses. These binaries are totally relocatable -
- their separate sections can relocated independently, allowing them to be
- shared on uClinux where possible. This should normally be enabled.
-
- (*) "Kernel image protection"
-
- This makes the protection register governing access to the core kernel
- image prohibit access by userspace programs. This option is available on
- uClinux only.
-
-There are also a number of settings in the "Kernel Hacking" section of the
-kernel configuration especially for debugging a kernel on this
-architecture. See the "gdbstub.txt" file for information about those.
-
-
-======================
-DEFAULT CONFIGURATIONS
-======================
-
-The kernel sources include a number of example default configurations:
-
- (*) defconfig-mb93091
-
- Default configuration for the MB93091-VDK with both CPU board and
- MB93090-MB00 motherboard running uClinux.
-
-
- (*) defconfig-mb93091-fb
-
- Default configuration for the MB93091-VDK with CPU board,
- MB93090-MB00 motherboard, and DAV board running uClinux.
- Includes framebuffer driver.
-
-
- (*) defconfig-mb93093
-
- Default configuration for the MB93093-PDK board running uClinux.
-
-
- (*) defconfig-cb70-standalone
-
- Default configuration for the MB93091-VDK with only CB70 CPU board
- running uClinux. This will use the CB70's DM9000 for network access.
-
-
- (*) defconfig-mmu
-
- Default configuration for the MB93091-VDK with both CB451 CPU board and
- MB93090-MB00 motherboard running MMU linux.
-
- (*) defconfig-mmu-audio
-
- Default configuration for the MB93091-VDK with CB451 CPU board, DAV
- board, and MB93090-MB00 motherboard running MMU linux. Includes
- audio driver.
-
- (*) defconfig-mmu-fb
-
- Default configuration for the MB93091-VDK with CB451 CPU board, DAV
- board, and MB93090-MB00 motherboard running MMU linux. Includes
- framebuffer driver.
-
- (*) defconfig-mmu-standalone
-
- Default configuration for the MB93091-VDK with only CB451 CPU board
- running MMU linux.
