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

631 comment "RAM configuration"
634 hex "Address of the base of RAM"
637 Define the address that RAM starts at. On many platforms this is
638 0, the base of the address space. And this is the default. Some
639 platforms choose to setup their RAM at other addresses within the
640 processor address space.
643 hex "Size of RAM (in bytes), or 0 for automatic"
646 Define the size of the system RAM. If you select 0 then the
647 kernel will try to probe the RAM size at runtime. This is not
648 supported on all CPU types.
651 hex "Address of the base of system vectors"
654 Define the address of the system vectors. Commonly this is
655 put at the start of RAM, but it doesn't have to be. On ColdFire
656 platforms this address is programmed into the VBR register, thus
657 actually setting the address to use.
660 hex "Address of the base of kernel code"
663 Typically on m68k systems the kernel will not start at the base
664 of RAM, but usually some small offset from it. Define the start
665 address of the kernel here. The most common setup will have the
666 processor vectors at the base of RAM and then the start of the
667 kernel. On some platforms some RAM is reserved for boot loaders
668 and the kernel starts after that. The 0x400 default was based on
669 a system with the RAM based at address 0, and leaving enough room
670 for the theoretical maximum number of 256 vectors.
673 prompt "RAM bus width"
679 Select the physical RAM data bus size. Not needed on most platforms,
680 so you can generally choose AUTO.
685 Configure RAM bus to be 8 bits wide.
690 Configure RAM bus to be 16 bits wide.
695 Configure RAM bus to be 32 bits wide.
699 comment "ROM configuration"
702 bool "Specify ROM linker regions"
705 Define a ROM region for the linker script. This creates a kernel
706 that can be stored in flash, with possibly the text, and data
707 regions being copied out to RAM at startup.
710 hex "Address of the base of ROM device"
714 Define the address that the ROM region starts at. Some platforms
715 use this to set their chip select region accordingly for the boot
719 hex "Address of the base of the ROM vectors"
723 This is almost always the same as the base of the ROM. Since on all
724 68000 type variants the vectors are at the base of the boot device
728 hex "Size of ROM vector region (in bytes)"
732 Define the size of the vector region in ROM. For most 68000
733 variants this would be 0x400 bytes in size. Set to 0 if you do
734 not want a vector region at the start of the ROM.
737 hex "Address of the base of system image in ROM"
741 Define the start address of the system image in ROM. Commonly this
742 is strait after the ROM vectors.
745 hex "Size of the ROM device"
749 Size of the ROM device. On some platforms this is used to setup
750 the chip select that controls the boot ROM device.
753 prompt "Kernel executes from"
755 Choose the memory type that the kernel will be running in.
760 The kernel will be resident in RAM when running.
765 The kernel will be resident in FLASH/ROM when running. This is
766 often referred to as Execute-in-Place (XIP), since the kernel
767 code executes from the position it is stored in the FLASH/ROM.
