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

159 config XILINX_UNCACHED_SHADOW
160 bool "Are you using uncached shadow for RAM ?"
161 depends on ADVANCED_OPTIONS && !MMU
164 This is needed to be able to allocate uncachable memory regions.
165 The feature requires the design to define the RAM memory controller
166 window to be twice as large as the actual physical memory.
168 config HIGHMEM_START_BOOL
169 bool "Set high memory pool address"
170 depends on ADVANCED_OPTIONS && HIGHMEM
172 This option allows you to set the base address of the kernel virtual
173 area used to map high memory pages. This can be useful in
174 optimizing the layout of kernel virtual memory.
176 Say N here unless you know what you are doing.
179 hex "Virtual start address of high memory pool" if HIGHMEM_START_BOOL
183 config LOWMEM_SIZE_BOOL
184 bool "Set maximum low memory"
185 depends on ADVANCED_OPTIONS && MMU
187 This option allows you to set the maximum amount of memory which
188 will be used as "low memory", that is, memory which the kernel can
189 access directly, without having to set up a kernel virtual mapping.
190 This can be useful in optimizing the layout of kernel virtual
193 Say N here unless you know what you are doing.
196 hex "Maximum low memory size (in bytes)" if LOWMEM_SIZE_BOOL
199 config KERNEL_START_BOOL
200 bool "Set custom kernel base address"
201 depends on ADVANCED_OPTIONS
203 This option allows you to set the kernel virtual address at which
204 the kernel will map low memory (the kernel image will be linked at
205 this address). This can be useful in optimizing the virtual memory
206 layout of the system.
208 Say N here unless you know what you are doing.
211 hex "Virtual address of kernel base" if KERNEL_START_BOOL
212 default "0xc0000000" if MMU
213 default KERNEL_BASE_ADDR if !MMU
215 config TASK_SIZE_BOOL
216 bool "Set custom user task size"
217 depends on ADVANCED_OPTIONS && MMU
219 This option allows you to set the amount of virtual address space
220 allocated to user tasks. This can be useful in optimizing the
221 virtual memory layout of the system.
223 Say N here unless you know what you are doing.
