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

162 bool "Set high memory pool address"
163 depends on ADVANCED_OPTIONS && HIGHMEM
165 This option allows you to set the base address of the kernel virtual
166 area used to map high memory pages. This can be useful in
167 optimizing the layout of kernel virtual memory.
169 Say N here unless you know what you are doing.

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

194 bool "Set custom kernel base address"
195 depends on ADVANCED_OPTIONS
197 This option allows you to set the kernel virtual address at which
198 the kernel will map low memory (the kernel image will be linked at
199 this address). This can be useful in optimizing the virtual memory
200 layout of the system.
202 Say N here unless you know what you are doing.

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

224 config CONSISTENT_START_BOOL
225 bool "Set custom consistent memory pool address"
226 depends on ADVANCED_OPTIONS && NOT_COHERENT_CACHE
228 This option allows you to set the base virtual address
229 of the the consistent memory pool. This pool of virtual
230 memory is used to make consistent memory allocations.
232 config CONSISTENT_START
233 hex "Base virtual address of consistent memory pool" if CONSISTENT_START_BOOL
