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. + + + |
