212 bool "Enable setting the CPU clock frequency"
215 On some CPU's you do not need to know what the core CPU clock
216 frequency is. On these you can disable clock setting. On some
217 traditional 68K parts, and on all ColdFire parts you need to set
218 the appropriate CPU clock frequency. On these devices many of the
219 onboard peripherals derive their timing from the master CPU clock
223 int "Set the core clock frequency"
227 Define the CPU clock frequency in use. This is the core clock
228 frequency, it may or may not be the same as the external clock
229 crystal fitted to your board. Some processors have an internal
230 PLL and can have their frequency programmed at run time, others
231 use internal dividers. In general the kernel won't setup a PLL
232 if it is fitted (there are some exceptions). This value will be
233 specific to the exact CPU that you are using.
236 int "Set the core/bus clock divide ratio"
240 On many SoC style CPUs the master CPU clock is also used to drive
241 on-chip peripherals. The clock that is distributed to these
242 peripherals is sometimes a fixed ratio of the master clock
243 frequency. If so then set this to the divider ratio of the
244 master clock to the peripheral clock. If not sure then select 1.

575 comment "RAM configuration"
578 hex "Address of the base of RAM"
581 Define the address that RAM starts at. On many platforms this is
582 0, the base of the address space. And this is the default. Some
583 platforms choose to setup their RAM at other addresses within the
584 processor address space.
587 hex "Size of RAM (in bytes), or 0 for automatic"
590 Define the size of the system RAM. If you select 0 then the
591 kernel will try to probe the RAM size at runtime. This is not
592 supported on all CPU types.
595 hex "Address of the base of system vectors"
598 Define the address of the system vectors. Commonly this is
599 put at the start of RAM, but it doesn't have to be. On ColdFire
600 platforms this address is programmed into the VBR register, thus
601 actually setting the address to use.
604 hex "Address of the base of kernel code"
607 Typically on m68k systems the kernel will not start at the base
608 of RAM, but usually some small offset from it. Define the start
609 address of the kernel here. The most common setup will have the
610 processor vectors at the base of RAM and then the start of the
611 kernel. On some platforms some RAM is reserved for boot loaders
612 and the kernel starts after that. The 0x400 default was based on
613 a system with the RAM based at address 0, and leaving enough room
614 for the theoretical maximum number of 256 vectors.
617 prompt "RAM bus width"
623 Select the physical RAM data bus size. Not needed on most platforms,
624 so you can generally choose AUTO.
629 Configure RAM bus to be 8 bits wide.
634 Configure RAM bus to be 16 bits wide.
639 Configure RAM bus to be 32 bits wide.
643 comment "ROM configuration"
646 bool "Specify ROM linker regions"
649 Define a ROM region for the linker script. This creates a kernel
650 that can be stored in flash, with possibly the text, and data
651 regions being copied out to RAM at startup.
654 hex "Address of the base of ROM device"
658 Define the address that the ROM region starts at. Some platforms
659 use this to set their chip select region accordingly for the boot
663 hex "Address of the base of the ROM vectors"
667 This is almost always the same as the base of the ROM. Since on all
668 68000 type variants the vectors are at the base of the boot device
672 hex "Size of ROM vector region (in bytes)"
676 Define the size of the vector region in ROM. For most 68000
677 variants this would be 0x400 bytes in size. Set to 0 if you do
678 not want a vector region at the start of the ROM.
681 hex "Address of the base of system image in ROM"
685 Define the start address of the system image in ROM. Commonly this
686 is strait after the ROM vectors.
689 hex "Size of the ROM device"
693 Size of the ROM device. On some platforms this is used to setup
694 the chip select that controls the boot ROM device.
697 prompt "Kernel executes from"
699 Choose the memory type that the kernel will be running in.
704 The kernel will be resident in RAM when running.
709 The kernel will be resident in FLASH/ROM when running. This is
710 often referred to as Execute-in-Place (XIP), since the kernel
711 code executes from the position it is stored in the FLASH/ROM.
