Use this option to have the compiler generate 48 function calls with 32-bit range. This will make the kernel both 49 larger and slower. 50 51 If unsure, say N. 52 53# Use the generic interrupt handling code in kernel/irq/ 54 55config CMDLINE_BOOL 56 bool "Default bootloader kernel arguments" 57 58config CMDLINE 59 string "Kernel command line" 60 depends on CMDLINE_BOOL 61 default "console=ttyS0,57600" 62 help 63 On some architectures there is currently no way for the boot loader 64 to pass arguments to the kernel. For these architectures, you should 65 supply some command-line options at build time by entering them 66 here. 67 68config CMDLINE_FORCE 69 bool "Force default kernel command string" 70 depends on CMDLINE_BOOL 71 default n 72 help 73 Set this to have arguments from the default kernel command string 74 override those passed by the boot loader. 75 76config CPU_BIG_ENDIAN 77 bool "Build big-endian kernel" 78 default n 79 help 80 Say Y if you plan on running a kernel in big-endian mode. 81 Note that your board must be properly built and your board 82 port must properly enable any big-endian related features 83 of your chipset/board/processor. 84 85config FORCE_MAX_ZONEORDER 86 int "Maximum zone order" 87 default "13" 88 help 89 The kernel memory allocator divides physically contiguous memory 90 blocks into "zones", where each zone is a power of two number of 91 pages. This option selects the largest power of two that the kernel 92 keeps in the memory allocator. If you need to allocate very large 93 blocks of physically contiguous memory, then you may need to 94 increase this value. 95 96 This config option is actually maximum order plus one. For example, 97 a value of 11 means that the largest free memory block is 2^10 pages. 98 99menu "Processor type and features" 100 101source "arch/c6x/platforms/Kconfig" 102 103config KERNEL_RAM_BASE_ADDRESS 104 hex "Virtual address of memory base" 105 default 0xe0000000 if SOC_TMS320C6455 106 default 0xe0000000 if SOC_TMS320C6457 107 default 0xe0000000 if SOC_TMS320C6472 108 default 0x80000000 109 110source "kernel/Kconfig.hz" 111 112endmenu 113
