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

157 config XILINX_UNCACHED_SHADOW
158 bool "Are you using uncached shadow for RAM ?"
159 depends on ADVANCED_OPTIONS && !MMU
162 This is needed to be able to allocate uncachable memory regions.
163 The feature requires the design to define the RAM memory controller
164 window to be twice as large as the actual physical memory.
166 config HIGHMEM_START_BOOL
167 bool "Set high memory pool address"
168 depends on ADVANCED_OPTIONS && HIGHMEM
170 This option allows you to set the base address of the kernel virtual
171 area used to map high memory pages. This can be useful in
172 optimizing the layout of kernel virtual memory.
174 Say N here unless you know what you are doing.
177 hex "Virtual start address of high memory pool" if HIGHMEM_START_BOOL
181 config LOWMEM_SIZE_BOOL
182 bool "Set maximum low memory"
183 depends on ADVANCED_OPTIONS && MMU
185 This option allows you to set the maximum amount of memory which
186 will be used as "low memory", that is, memory which the kernel can
187 access directly, without having to set up a kernel virtual mapping.
188 This can be useful in optimizing the layout of kernel virtual
191 Say N here unless you know what you are doing.
194 hex "Maximum low memory size (in bytes)" if LOWMEM_SIZE_BOOL
197 config KERNEL_START_BOOL
198 bool "Set custom kernel base address"
199 depends on ADVANCED_OPTIONS
201 This option allows you to set the kernel virtual address at which
202 the kernel will map low memory (the kernel image will be linked at
203 this address). This can be useful in optimizing the virtual memory
204 layout of the system.
206 Say N here unless you know what you are doing.
209 hex "Virtual address of kernel base" if KERNEL_START_BOOL
210 default "0xc0000000" if MMU
211 default KERNEL_BASE_ADDR if !MMU
213 config TASK_SIZE_BOOL
214 bool "Set custom user task size"
215 depends on ADVANCED_OPTIONS && MMU
217 This option allows you to set the amount of virtual address space
218 allocated to user tasks. This can be useful in optimizing the
219 virtual memory layout of the system.
221 Say N here unless you know what you are doing.
