105 bool "Default bootloader kernel arguments"
108 string "Default kernel command string"
109 depends on CMDLINE_BOOL
110 default "console=ttyUL0,115200"
112 On some architectures there is currently no way for the boot loader
113 to pass arguments to the kernel. For these architectures, you should
114 supply some command-line options at build time by entering them
118 bool "Force default kernel command string"
119 depends on CMDLINE_BOOL
122 Set this to have arguments from the default kernel command string
123 override those passed by the boot loader.
128 config PROC_DEVICETREE
129 bool "Support for device tree in /proc"
132 This option adds a device-tree directory under /proc which contains
133 an image of the device tree that the kernel copies from Open
134 Firmware or other boot firmware. If unsure, say Y here.
138 menu "Advanced setup"
140 config ADVANCED_OPTIONS
141 bool "Prompt for advanced kernel configuration options"
144 This option will enable prompting for a variety of advanced kernel
145 configuration options. These options can cause the kernel to not
146 work if they are set incorrectly, but can be used to optimize certain
147 aspects of kernel memory management.
149 Unless you know what you are doing, say N here.

154 config HIGHMEM_START_BOOL
155 bool "Set high memory pool address"
156 depends on ADVANCED_OPTIONS && HIGHMEM
158 This option allows you to set the base address of the kernel virtual
159 area used to map high memory pages. This can be useful in
160 optimizing the layout of kernel virtual memory.
162 Say N here unless you know what you are doing.

170 bool "Set maximum low memory"
171 depends on ADVANCED_OPTIONS
173 This option allows you to set the maximum amount of memory which
174 will be used as "low memory", that is, memory which the kernel can
175 access directly, without having to set up a kernel virtual mapping.
176 This can be useful in optimizing the layout of kernel virtual
179 Say N here unless you know what you are doing.

187 bool "Set custom kernel base address"
188 depends on ADVANCED_OPTIONS
190 This option allows you to set the kernel virtual address at which
191 the kernel will map low memory (the kernel image will be linked at
192 this address). This can be useful in optimizing the virtual memory
193 layout of the system.
195 Say N here unless you know what you are doing.

204 depends on ADVANCED_OPTIONS
206 This option allows you to set the amount of virtual address space
207 allocated to user tasks. This can be useful in optimizing the
208 virtual memory layout of the system.
210 Say N here unless you know what you are doing.

217 config CONSISTENT_START_BOOL
218 bool "Set custom consistent memory pool address"
219 depends on ADVANCED_OPTIONS && NOT_COHERENT_CACHE
221 This option allows you to set the base virtual address
222 of the the consistent memory pool. This pool of virtual
223 memory is used to make consistent memory allocations.
225 config CONSISTENT_START
226 hex "Base virtual address of consistent memory pool" if CONSISTENT_START_BOOL
