94 string "Default kernel command string"
95 depends on CMDLINE_BOOL
96 default "console=ttyUL0,115200"
98 On some architectures there is currently no way for the boot loader
99 to pass arguments to the kernel. For these architectures, you should
100 supply some command-line options at build time by entering them
104 bool "Force default kernel command string"
105 depends on CMDLINE_BOOL
108 Set this to have arguments from the default kernel command string
109 override those passed by the boot loader.
114 config PROC_DEVICETREE
115 bool "Support for device tree in /proc"
118 This option adds a device-tree directory under /proc which contains
119 an image of the device tree that the kernel copies from Open
120 Firmware or other boot firmware. If unsure, say Y here.

126 config ADVANCED_OPTIONS
127 bool "Prompt for advanced kernel configuration options"
130 This option will enable prompting for a variety of advanced kernel
131 configuration options. These options can cause the kernel to not
132 work if they are set incorrectly, but can be used to optimize certain
133 aspects of kernel memory management.
135 Unless you know what you are doing, say N here.

141 bool "Set high memory pool address"
142 depends on ADVANCED_OPTIONS && HIGHMEM
144 This option allows you to set the base address of the kernel virtual
145 area used to map high memory pages. This can be useful in
146 optimizing the layout of kernel virtual memory.
148 Say N here unless you know what you are doing.

157 depends on ADVANCED_OPTIONS
159 This option allows you to set the maximum amount of memory which
160 will be used as "low memory", that is, memory which the kernel can
161 access directly, without having to set up a kernel virtual mapping.
162 This can be useful in optimizing the layout of kernel virtual
165 Say N here unless you know what you are doing.

174 depends on ADVANCED_OPTIONS
176 This option allows you to set the kernel virtual address at which
177 the kernel will map low memory (the kernel image will be linked at
178 this address). This can be useful in optimizing the virtual memory
179 layout of the system.
181 Say N here unless you know what you are doing.

190 depends on ADVANCED_OPTIONS
192 This option allows you to set the amount of virtual address space
193 allocated to user tasks. This can be useful in optimizing the
194 virtual memory layout of the system.

203 config CONSISTENT_START_BOOL
204 bool "Set custom consistent memory pool address"
205 depends on ADVANCED_OPTIONS && NOT_COHERENT_CACHE
207 This option allows you to set the base virtual address
208 of the the consistent memory pool. This pool of virtual
209 memory is used to make consistent memory allocations.
