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

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

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

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

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

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