112 This option enables support for the Sun 3x series of workstations.
113 Be warned that this support is very experimental.
114 Note that Sun 3x kernels are not compatible with Sun 3 hardware.
115 General Linux information on the Sun 3x series (now discontinued)
116 is at <http://www.angelfire.com/ca2/tech68k/sun3.html>.

137 select LEGACY_TIMER_TICK
141 This option enables support for the Sun 3 series of workstations
142 (3/50, 3/60, 3/1xx, 3/2xx systems). Enabling this option requires
143 that all other hardware types must be disabled, as Sun 3 kernels
144 are incompatible with all other m68k targets (including Sun 3x!).

329 comment "Machine Options"
332 bool "Support for U-Boot command line parameters"
334 If you say Y here kernel will try to collect command
335 line parameters from the initial u-boot stack.
338 bool "Use 4Kb for kernel stacks instead of 8Kb"
341 If you say Y here the kernel will use a 4Kb stacksize for the
342 kernel stack attached to each process/thread. This facilitates
343 running more threads on a system and also reduces the pressure
344 on the VM subsystem for higher order allocations.
346 comment "RAM configuration"
349 hex "Address of the base of RAM"
352 Define the address that RAM starts at. On many platforms this is
353 0, the base of the address space. And this is the default. Some
354 platforms choose to setup their RAM at other addresses within the
355 processor address space.
358 hex "Size of RAM (in bytes), or 0 for automatic"
361 Define the size of the system RAM. If you select 0 then the
362 kernel will try to probe the RAM size at runtime. This is not
363 supported on all CPU types.
366 hex "Address of the base of system vectors"
369 Define the address of the system vectors. Commonly this is
370 put at the start of RAM, but it doesn't have to be. On ColdFire
371 platforms this address is programmed into the VBR register, thus
372 actually setting the address to use.
375 hex "Address of the MBAR (internal peripherals)"
379 Define the address of the internal system peripherals. This value
380 is set in the processors MBAR register. This is generally setup by
381 the boot loader, and will not be written by the kernel. By far most
382 ColdFire boards use the default 0x10000000 value, so if unsure then
386 hex "Address of the IPSBAR (internal peripherals)"
388 depends on HAVE_IPSBAR
390 Define the address of the internal system peripherals. This value
391 is set in the processors IPSBAR register. This is generally setup by
392 the boot loader, and will not be written by the kernel. By far most
393 ColdFire boards use the default 0x40000000 value, so if unsure then
397 hex "Address of the base of kernel code"
400 Typically on m68k systems the kernel will not start at the base
401 of RAM, but usually some small offset from it. Define the start
402 address of the kernel here. The most common setup will have the
403 processor vectors at the base of RAM and then the start of the
404 kernel. On some platforms some RAM is reserved for boot loaders
405 and the kernel starts after that. The 0x400 default was based on
406 a system with the RAM based at address 0, and leaving enough room
407 for the theoretical maximum number of 256 vectors.
409 comment "ROM configuration"
412 bool "Specify ROM linker regions"
414 Define a ROM region for the linker script. This creates a kernel
415 that can be stored in flash, with possibly the text, and data
416 regions being copied out to RAM at startup.
419 hex "Address of the base of ROM device"
423 Define the address that the ROM region starts at. Some platforms
424 use this to set their chip select region accordingly for the boot
428 hex "Address of the base of the ROM vectors"
432 This is almost always the same as the base of the ROM. Since on all
433 68000 type variants the vectors are at the base of the boot device
437 hex "Address of the base of system image in ROM"
441 Define the start address of the system image in ROM. Commonly this
442 is strait after the ROM vectors.
445 hex "Size of the ROM device"
449 Size of the ROM device. On some platforms this is used to setup
450 the chip select that controls the boot ROM device.
453 prompt "Kernel executes from"
455 Choose the memory type that the kernel will be running in.
460 The kernel will be resident in RAM when running.
465 The kernel will be resident in FLASH/ROM when running. This is
466 often referred to as Execute-in-Place (XIP), since the kernel
467 code executes from the position it is stored in the FLASH/ROM.
