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

144 config HIGHMEM_START_BOOL
145 bool "Set high memory pool address"
146 depends on ADVANCED_OPTIONS && HIGHMEM
148 This option allows you to set the base address of the kernel virtual
149 area used to map high memory pages. This can be useful in
150 optimizing the layout of kernel virtual memory.
152 Say N here unless you know what you are doing.

160 bool "Set maximum low memory"
161 depends on ADVANCED_OPTIONS
163 This option allows you to set the maximum amount of memory which
164 will be used as "low memory", that is, memory which the kernel can
165 access directly, without having to set up a kernel virtual mapping.
166 This can be useful in optimizing the layout of kernel virtual
169 Say N here unless you know what you are doing.

177 bool "Set custom kernel base address"
178 depends on ADVANCED_OPTIONS
180 This option allows you to set the kernel virtual address at which
181 the kernel will map low memory (the kernel image will be linked at
182 this address). This can be useful in optimizing the virtual memory
183 layout of the system.
185 Say N here unless you know what you are doing.

193 bool "Set custom user task size"
194 depends on ADVANCED_OPTIONS
196 This option allows you to set the amount of virtual address space
197 allocated to user tasks. This can be useful in optimizing the
198 virtual memory layout of the system.
200 Say N here unless you know what you are doing.

207 config CONSISTENT_START_BOOL
208 bool "Set custom consistent memory pool address"
209 depends on ADVANCED_OPTIONS && NOT_COHERENT_CACHE
211 This option allows you to set the base virtual address
212 of the the consistent memory pool. This pool of virtual
213 memory is used to make consistent memory allocations.
215 config CONSISTENT_START
216 hex "Base virtual address of consistent memory pool" if CONSISTENT_START_BOOL

226 is used to make consistent memory allocations.
