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