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. - - - |
