comment "Board Settings"
config BOARD_LOOPSPERMSEC
int "Loops per millisecond"
help
Must be calibrated for correct operation of delay loops.
You simply use a stop watch to measure the 100 second delay
then adjust CONFIG_BOARD_LOOPSPERMSEC until it is actually
is 100 seconds.
config DRAM_START
hex "DRAM start physical address"
help
The physical start address of installed RAM. Despite the naming,
this may be SDRAM or SRAM or any other RAM technology that support
program execution.
config DRAM_VSTART
hex "DRAM start virtual address"
depends on ARCH_HAVE_MMU
help
The virtual start address of installed RAM. Despite the naming,
this may be SDRAM or SRAM or any other RAM technology that support
program execution.
config DRAM_SIZE
int "DRAM size"
help
The size in bytes of the installed RAM. Despite the naming,
this may be SDRAM or SRAM or any other RAM technology that support
program execution.
config ARCH_HAVE_INTERRUPTSTACK
bool
config ARCH_INTERRUPTSTACK
int "Interrupt Stack Size"
depends on ARCH_HAVE_INTERRUPTSTACK
default 0
---help---
This architecture supports an interrupt stack. If defined, this symbol
will be the size of the interrupt stack in bytes. If not defined (or
defined to be zero), the user task stacks will be used during interrupt
handling.

bool "Run from external SRAM"
---help---
Some configuration support booting and running from external SRAM.
config BOOT_RUNFROMFLASH
bool "Boot and run from flash"
---help---
Most configurations support XIP operation from FLASH but must copy
initialized .data sections to RAM. (This is the default).
config BOOT_RUNFROMISRAM
bool "Boot and run from internal SRAM"
---help---
Some configuration support booting and running from internal SRAM.
config BOOT_RUNFROMSDRAM
bool "Boot and run from external SDRAM"
---help---
Some configuration support booting and running from external SDRAM.
config BOOT_COPYTORAM
bool "Boot from FLASH but copy to ram"
---help---
Some configurations boot in FLASH but copy themselves entirely into
RAM for better performance.
