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

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