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

624 comment "RAM configuration"
627 hex "Address of the base of RAM"
630 Define the address that RAM starts at. On many platforms this is
631 0, the base of the address space. And this is the default. Some
632 platforms choose to setup their RAM at other addresses within the
633 processor address space.
636 hex "Size of RAM (in bytes), or 0 for automatic"
639 Define the size of the system RAM. If you select 0 then the
640 kernel will try to probe the RAM size at runtime. This is not
641 supported on all CPU types.
644 hex "Address of the base of system vectors"
647 Define the address of the system vectors. Commonly this is
648 put at the start of RAM, but it doesn't have to be. On ColdFire
649 platforms this address is programmed into the VBR register, thus
650 actually setting the address to use.
653 hex "Address of the base of kernel code"
656 Typically on m68k systems the kernel will not start at the base
657 of RAM, but usually some small offset from it. Define the start
658 address of the kernel here. The most common setup will have the
659 processor vectors at the base of RAM and then the start of the
660 kernel. On some platforms some RAM is reserved for boot loaders
661 and the kernel starts after that. The 0x400 default was based on
662 a system with the RAM based at address 0, and leaving enough room
663 for the theoretical maximum number of 256 vectors.
666 prompt "RAM bus width"
672 Select the physical RAM data bus size. Not needed on most platforms,
673 so you can generally choose AUTO.
678 Configure RAM bus to be 8 bits wide.
683 Configure RAM bus to be 16 bits wide.
688 Configure RAM bus to be 32 bits wide.
692 comment "ROM configuration"
695 bool "Specify ROM linker regions"
698 Define a ROM region for the linker script. This creates a kernel
699 that can be stored in flash, with possibly the text, and data
700 regions being copied out to RAM at startup.
703 hex "Address of the base of ROM device"
707 Define the address that the ROM region starts at. Some platforms
708 use this to set their chip select region accordingly for the boot
712 hex "Address of the base of the ROM vectors"
716 This is almost always the same as the base of the ROM. Since on all
717 68000 type variants the vectors are at the base of the boot device
721 hex "Size of ROM vector region (in bytes)"
725 Define the size of the vector region in ROM. For most 68000
726 variants this would be 0x400 bytes in size. Set to 0 if you do
727 not want a vector region at the start of the ROM.
730 hex "Address of the base of system image in ROM"
734 Define the start address of the system image in ROM. Commonly this
735 is strait after the ROM vectors.
738 hex "Size of the ROM device"
742 Size of the ROM device. On some platforms this is used to setup
743 the chip select that controls the boot ROM device.
746 prompt "Kernel executes from"
748 Choose the memory type that the kernel will be running in.
753 The kernel will be resident in RAM when running.
758 The kernel will be resident in FLASH/ROM when running. This is
759 often referred to as Execute-in-Place (XIP), since the kernel
760 code executes from the position it is stored in the FLASH/ROM.
