183 bool "Enable setting the CPU clock frequency"
186 On some CPU's you do not need to know what the core CPU clock
187 frequency is. On these you can disable clock setting. On some
188 traditional 68K parts, and on all ColdFire parts you need to set
189 the appropriate CPU clock frequency. On these devices many of the
190 onboard peripherals derive their timing from the master CPU clock
194 int "Set the core clock frequency"
198 Define the CPU clock frequency in use. This is the core clock
199 frequency, it may or may not be the same as the external clock
200 crystal fitted to your board. Some processors have an internal
201 PLL and can have their frequency programmed at run time, others
202 use internal dividers. In general the kernel won't setup a PLL
203 if it is fitted (there are some exceptions). This value will be
204 specific to the exact CPU that you are using.
207 int "Set the core/bus clock divide ratio"
211 On many SoC style CPUs the master CPU clock is also used to drive
212 on-chip peripherals. The clock that is distributed to these
213 peripherals is sometimes a fixed ratio of the master clock
214 frequency. If so then set this to the divider ratio of the
215 master clock to the peripheral clock. If not sure then select 1.

536 If you say Y here the kernel will use a 4Kb stacksize for the
537 kernel stack attached to each process/thread. This facilitates
538 running more threads on a system and also reduces the pressure
539 on the VM subsystem for higher order allocations.

546 comment "RAM configuration"
549 hex "Address of the base of RAM"
552 Define the address that RAM starts at. On many platforms this is
553 0, the base of the address space. And this is the default. Some
554 platforms choose to setup their RAM at other addresses within the
555 processor address space.
558 hex "Size of RAM (in bytes), or 0 for automatic"
561 Define the size of the system RAM. If you select 0 then the
562 kernel will try to probe the RAM size at runtime. This is not
563 supported on all CPU types.
566 hex "Address of the base of system vectors"
569 Define the address of the system vectors. Commonly this is
570 put at the start of RAM, but it doesn't have to be. On ColdFire
571 platforms this address is programmed into the VBR register, thus
572 actually setting the address to use.
575 hex "Address of the base of kernel code"
578 Typically on m68k systems the kernel will not start at the base
579 of RAM, but usually some small offset from it. Define the start
580 address of the kernel here. The most common setup will have the
581 processor vectors at the base of RAM and then the start of the
582 kernel. On some platforms some RAM is reserved for boot loaders
583 and the kernel starts after that. The 0x400 default was based on
584 a system with the RAM based at address 0, and leaving enough room
585 for the theoretical maximum number of 256 vectors.
588 prompt "RAM bus width"
594 Select the physical RAM data bus size. Not needed on most platforms,
595 so you can generally choose AUTO.
600 Configure RAM bus to be 8 bits wide.
605 Configure RAM bus to be 16 bits wide.
610 Configure RAM bus to be 32 bits wide.
614 comment "ROM configuration"
617 bool "Specify ROM linker regions"
620 Define a ROM region for the linker script. This creates a kernel
621 that can be stored in flash, with possibly the text, and data
622 regions being copied out to RAM at startup.
625 hex "Address of the base of ROM device"
629 Define the address that the ROM region starts at. Some platforms
630 use this to set their chip select region accordingly for the boot
634 hex "Address of the base of the ROM vectors"
638 This is almost always the same as the base of the ROM. Since on all
639 68000 type variants the vectors are at the base of the boot device
643 hex "Size of ROM vector region (in bytes)"
647 Define the size of the vector region in ROM. For most 68000
648 variants this would be 0x400 bytes in size. Set to 0 if you do
649 not want a vector region at the start of the ROM.
652 hex "Address of the base of system image in ROM"
656 Define the start address of the system image in ROM. Commonly this
657 is strait after the ROM vectors.
660 hex "Size of the ROM device"
664 Size of the ROM device. On some platforms this is used to setup
665 the chip select that controls the boot ROM device.
668 prompt "Kernel executes from"
670 Choose the memory type that the kernel will be running in.
675 The kernel will be resident in RAM when running.
680 The kernel will be resident in FLASH/ROM when running. This is
681 often referred to as Execute-in-Place (XIP), since the kernel
682 code executes from the position it is stored in the FLASH/ROM.
