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