79 prompt "Archimedes/A5000 Implementations"
84 Say Y to support the Acorn Archimedes.
86 The Acorn Archimedes was an personal computer based on an 8MHz ARM2
87 processor, released in 1987. It supported up to 16MB of RAM in
88 later models and floppy, harddisc, ethernet etc.
92 select ARCH_MAY_HAVE_PC_FDC
94 Say Y here to support the Acorn A5000.
97 internal IDE disk and CD-ROM interface, serial and parallel port,
98 and the floppy drive. Note that on some A5000s the floppy is
99 plugged into the wrong socket on the motherboard.
102 bool "2MB physical memory (broken)"
104 Say Y here if your Archimedes or A5000 system has only 2MB of
105 memory, otherwise say N. The resulting kernel will not run on a
106 machine with 4MB of memory.
116 # Compressed boot loader in ROM. Yes, we really want to ask about
117 # TEXT and BSS so we preserve their values in the config files.
119 bool "Compressed boot loader in ROM/flash"
121 Say Y here if you intend to execute your compressed kernel image (zImage)
122 directly from ROM or flash. If unsure, say N.
124 config ZBOOT_ROM_TEXT
126 hex "Compressed ROM boot loader base address"
129 The base address for zImage. Unless you have special requirements, you
130 should not change this value.
134 hex "Compressed ROM boot loader BSS address"
137 The base address of 64KiB of read/write memory, which must be available
138 while the decompressor is running. Unless you have special requirements,
139 you should not change this value.
142 bool "Execute In Place (XIP) kernel image"
144 Select this option to create a kernel that can be programmed into
147 comment "At least one math emulation must be selected"
150 tristate "NWFPE math emulation"
152 Say Y to include the NWFPE floating point emulator in the kernel.
153 This is necessary to run most binaries. Linux does not currently
154 support floating point hardware so you need to say Y here even if
155 your machine has an FPA or floating point co-processor module.
157 It is also possible to say M to build the emulator as a module
158 (nwfpe) or indeed to leave it out altogether. However, unless you
159 know what you are doing this can easily render your machine
160 unbootable. Saying Y is the safe option.
162 You may say N here if you are going to load the Acorn FPEmulator
165 source "fs/Kconfig.binfmt"
168 bool "Preemptible Kernel (EXPERIMENTAL)"
169 depends on CPU_32 && EXPERIMENTAL
171 This option reduces the latency of the kernel when reacting to
172 real-time or interactive events by allowing a low priority process to
173 be preempted even if it is in kernel mode executing a system call.
174 This allows applications to run more reliably even when the system is
177 Say Y here if you are building a kernel for a desktop, embedded
178 or real-time system. Say N if you are unsure.
181 tristate "RISC OS personality"
184 Say Y here to include the kernel code necessary if you want to run
185 Acorn RISC OS/Arthur binaries under Linux. This code is still very
186 experimental; if this sounds frightening, say N and sleep in peace.
187 You can also say M here to compile this support as a module (which
188 will be called arthur).
191 string "Default kernel command string"
194 On some architectures (EBSA110 and CATS), there is currently no way
195 for the boot loader to pass arguments to the kernel. For these
196 architectures, you should supply some command-line options at build
197 time by entering them here. As a minimum, you should specify the
198 memory size and the root device (e.g., mem=64M root=/dev/nfs).
