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.
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.

146 config ADVANCED_OPTIONS
147 bool "Prompt for advanced kernel configuration options"
150 This option will enable prompting for a variety of advanced kernel
151 configuration options. These options can cause the kernel to not
152 work if they are set incorrectly, but can be used to optimize certain
153 aspects of kernel memory management.
155 Unless you know what you are doing, say N here.

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

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

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

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

223 config CONSISTENT_START_BOOL
224 bool "Set custom consistent memory pool address"
225 depends on ADVANCED_OPTIONS && NOT_COHERENT_CACHE
227 This option allows you to set the base virtual address
228 of the the consistent memory pool. This pool of virtual
229 memory is used to make consistent memory allocations.
