96 depends on CMDLINE_BOOL
97 default "console=ttyUL0,115200"
99 On some architectures there is currently no way for the boot loader
100 to pass arguments to the kernel. For these architectures, you should
101 supply some command-line options at build time by entering them
105 bool "Force default kernel command string"
106 depends on CMDLINE_BOOL
109 Set this to have arguments from the default kernel command string
110 override those passed by the boot loader.
115 config PROC_DEVICETREE
116 bool "Support for device tree in /proc"
119 This option adds a device-tree directory under /proc which contains
120 an image of the device tree that the kernel copies from Open
121 Firmware or other boot firmware. If unsure, say Y here.
125 menu "Advanced setup"
127 config ADVANCED_OPTIONS
128 bool "Prompt for advanced kernel configuration options"
131 This option will enable prompting for a variety of advanced kernel
132 configuration options. These options can cause the kernel to not
133 work if they are set incorrectly, but can be used to optimize certain
134 aspects of kernel memory management.
136 Unless you know what you are doing, say N here.

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

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

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

191 depends on ADVANCED_OPTIONS
193 This option allows you to set the amount of virtual address space
194 allocated to user tasks. This can be useful in optimizing the
195 virtual memory layout of the system.
197 Say N here unless you know what you are doing.

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

223 is used to make consistent memory allocations.
