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.

160 bool "Set high memory pool address"
161 depends on ADVANCED_OPTIONS && HIGHMEM
163 This option allows you to set the base address of the kernel virtual
164 area used to map high memory pages. This can be useful in
165 optimizing the layout of kernel virtual memory.
167 Say N here unless you know what you are doing.
170 hex "Virtual start address of high memory pool" if HIGHMEM_START_BOOL

175 bool "Set maximum low memory"
176 depends on ADVANCED_OPTIONS && MMU
178 This option allows you to set the maximum amount of memory which
179 will be used as "low memory", that is, memory which the kernel can
180 access directly, without having to set up a kernel virtual mapping.
181 This can be useful in optimizing the layout of kernel virtual
184 Say N here unless you know what you are doing.
187 hex "Maximum low memory size (in bytes)" if LOWMEM_SIZE_BOOL
190 config KERNEL_START_BOOL
191 bool "Set custom kernel base address"
192 depends on ADVANCED_OPTIONS
194 This option allows you to set the kernel virtual address at which
195 the kernel will map low memory (the kernel image will be linked at
196 this address). This can be useful in optimizing the virtual memory
197 layout of the system.
199 Say N here unless you know what you are doing.

208 depends on ADVANCED_OPTIONS && MMU
210 This option allows you to set the amount of virtual address space
211 allocated to user tasks. This can be useful in optimizing the
212 virtual memory layout of the system.
