Use this option to have the compiler generate 50 function calls with 32-bit range. This will make the kernel both 51 larger and slower. 52 53 If unsure, say N. 54 55# Use the generic interrupt handling code in kernel/irq/ 56 57config CMDLINE_BOOL 58 bool "Default bootloader kernel arguments" 59 60config CMDLINE 61 string "Kernel command line" 62 depends on CMDLINE_BOOL 63 default "console=ttyS0,57600" 64 help 65 On some architectures there is currently no way for the boot loader 66 to pass arguments to the kernel. For these architectures, you should 67 supply some command-line options at build time by entering them 68 here. 69 70config CMDLINE_FORCE 71 bool "Force default kernel command string" 72 depends on CMDLINE_BOOL 73 default n 74 help 75 Set this to have arguments from the default kernel command string 76 override those passed by the boot loader. 77 78config CPU_BIG_ENDIAN 79 bool "Build big-endian kernel" 80 default n 81 help 82 Say Y if you plan on running a kernel in big-endian mode. 83 Note that your board must be properly built and your board 84 port must properly enable any big-endian related features 85 of your chipset/board/processor. 86 87config FORCE_MAX_ZONEORDER 88 int "Maximum zone order" 89 default "13" 90 help 91 The kernel memory allocator divides physically contiguous memory 92 blocks into "zones", where each zone is a power of two number of 93 pages. This option selects the largest power of two that the kernel 94 keeps in the memory allocator. If you need to allocate very large 95 blocks of physically contiguous memory, then you may need to 96 increase this value. 97 98 This config option is actually maximum order plus one. For example, 99 a value of 11 means that the largest free memory block is 2^10 pages. 100 101menu "Processor type and features" 102 103source "arch/c6x/platforms/Kconfig" 104 105config KERNEL_RAM_BASE_ADDRESS 106 hex "Virtual address of memory base" 107 default 0xe0000000 if SOC_TMS320C6455 108 default 0xe0000000 if SOC_TMS320C6457 109 default 0xe0000000 if SOC_TMS320C6472 110 default 0x80000000 111 112source "kernel/Kconfig.hz" 113 114endmenu 115
