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

560 comment "RAM configuration"
563 hex "Address of the base of RAM"
566 Define the address that RAM starts at. On many platforms this is
567 0, the base of the address space. And this is the default. Some
568 platforms choose to setup their RAM at other addresses within the
569 processor address space.
572 hex "Size of RAM (in bytes), or 0 for automatic"
575 Define the size of the system RAM. If you select 0 then the
576 kernel will try to probe the RAM size at runtime. This is not
577 supported on all CPU types.
580 hex "Address of the base of system vectors"
583 Define the address of the system vectors. Commonly this is
584 put at the start of RAM, but it doesn't have to be. On ColdFire
585 platforms this address is programmed into the VBR register, thus
586 actually setting the address to use.
589 hex "Address of the base of kernel code"
592 Typically on m68k systems the kernel will not start at the base
593 of RAM, but usually some small offset from it. Define the start
594 address of the kernel here. The most common setup will have the
595 processor vectors at the base of RAM and then the start of the
596 kernel. On some platforms some RAM is reserved for boot loaders
597 and the kernel starts after that. The 0x400 default was based on
598 a system with the RAM based at address 0, and leaving enough room
599 for the theoretical maximum number of 256 vectors.
602 prompt "RAM bus width"
608 Select the physical RAM data bus size. Not needed on most platforms,
609 so you can generally choose AUTO.
614 Configure RAM bus to be 8 bits wide.
619 Configure RAM bus to be 16 bits wide.
624 Configure RAM bus to be 32 bits wide.
628 comment "ROM configuration"
631 bool "Specify ROM linker regions"
634 Define a ROM region for the linker script. This creates a kernel
635 that can be stored in flash, with possibly the text, and data
636 regions being copied out to RAM at startup.
639 hex "Address of the base of ROM device"
643 Define the address that the ROM region starts at. Some platforms
644 use this to set their chip select region accordingly for the boot
648 hex "Address of the base of the ROM vectors"
652 This is almost always the same as the base of the ROM. Since on all
653 68000 type variants the vectors are at the base of the boot device
657 hex "Size of ROM vector region (in bytes)"
661 Define the size of the vector region in ROM. For most 68000
662 variants this would be 0x400 bytes in size. Set to 0 if you do
663 not want a vector region at the start of the ROM.
666 hex "Address of the base of system image in ROM"
670 Define the start address of the system image in ROM. Commonly this
671 is strait after the ROM vectors.
674 hex "Size of the ROM device"
678 Size of the ROM device. On some platforms this is used to setup
679 the chip select that controls the boot ROM device.
682 prompt "Kernel executes from"
684 Choose the memory type that the kernel will be running in.
689 The kernel will be resident in RAM when running.
694 The kernel will be resident in FLASH/ROM when running. This is
695 often referred to as Execute-in-Place (XIP), since the kernel
696 code executes from the position it is stored in the FLASH/ROM.
