327 comment "Machine Options"
330 bool "Support for U-Boot command line parameters"
333 If you say Y here kernel will try to collect command
334 line parameters from the initial u-boot stack.
337 bool "Use 4Kb for kernel stacks instead of 8Kb"
340 If you say Y here the kernel will use a 4Kb stacksize for the
341 kernel stack attached to each process/thread. This facilitates
342 running more threads on a system and also reduces the pressure
343 on the VM subsystem for higher order allocations.
345 comment "RAM configuration"
348 hex "Address of the base of RAM"
351 Define the address that RAM starts at. On many platforms this is
352 0, the base of the address space. And this is the default. Some
353 platforms choose to setup their RAM at other addresses within the
354 processor address space.
357 hex "Size of RAM (in bytes), or 0 for automatic"
360 Define the size of the system RAM. If you select 0 then the
361 kernel will try to probe the RAM size at runtime. This is not
362 supported on all CPU types.
365 hex "Address of the base of system vectors"
368 Define the address of the system vectors. Commonly this is
369 put at the start of RAM, but it doesn't have to be. On ColdFire
370 platforms this address is programmed into the VBR register, thus
371 actually setting the address to use.
374 hex "Address of the MBAR (internal peripherals)"
378 Define the address of the internal system peripherals. This value
379 is set in the processors MBAR register. This is generally setup by
380 the boot loader, and will not be written by the kernel. By far most
381 ColdFire boards use the default 0x10000000 value, so if unsure then
385 hex "Address of the IPSBAR (internal peripherals)"
387 depends on HAVE_IPSBAR
389 Define the address of the internal system peripherals. This value
390 is set in the processors IPSBAR register. This is generally setup by
391 the boot loader, and will not be written by the kernel. By far most
392 ColdFire boards use the default 0x40000000 value, so if unsure then
396 hex "Address of the base of kernel code"
399 Typically on m68k systems the kernel will not start at the base
400 of RAM, but usually some small offset from it. Define the start
401 address of the kernel here. The most common setup will have the
402 processor vectors at the base of RAM and then the start of the
403 kernel. On some platforms some RAM is reserved for boot loaders
404 and the kernel starts after that. The 0x400 default was based on
405 a system with the RAM based at address 0, and leaving enough room
406 for the theoretical maximum number of 256 vectors.
408 comment "ROM configuration"
411 bool "Specify ROM linker regions"
413 Define a ROM region for the linker script. This creates a kernel
414 that can be stored in flash, with possibly the text, and data
415 regions being copied out to RAM at startup.
418 hex "Address of the base of the ROM vectors"
422 This is almost always the same as the base of the ROM. Since on all
423 68000 type variants the vectors are at the base of the boot device
427 hex "Address of the base of system image in ROM"
431 Define the start address of the system image in ROM. Commonly this
432 is strait after the ROM vectors.
435 prompt "Kernel executes from"
437 Choose the memory type that the kernel will be running in.
442 The kernel will be resident in RAM when running.
448 The kernel will be resident in FLASH/ROM when running. This is
449 often referred to as Execute-in-Place (XIP), since the kernel
450 code executes from the position it is stored in the FLASH/ROM.
