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

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

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

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

197 depends on ADVANCED_OPTIONS
199 This option allows you to set the amount of virtual address space
200 allocated to user tasks. This can be useful in optimizing the
201 virtual memory layout of the system.

210 config CONSISTENT_START_BOOL
211 bool "Set custom consistent memory pool address"
212 depends on ADVANCED_OPTIONS && NOT_COHERENT_CACHE
214 This option allows you to set the base virtual address
215 of the the consistent memory pool. This pool of virtual
216 memory is used to make consistent memory allocations.
