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