so that FLASH can be reconfigured while the MCU executes out of
SRAM.

comment "Board Settings"
config BOARD_LOOPSPERMSEC
int "Delay loops per millisecond"
default 5000
---help---
Simple delay loops are used by some logic, especially during boot-up,
driver initialization. These delay loops must be calibrated for each
board in order to assure accurate timing by the delay loops.
config ARCH_CALIBRATION
bool "Calibrate delay loop"
default n
---help---
Enables some built in instrumentation that causes a 100 second delay
during boot-up. This 100 second delay serves no purpose other than it
allows you to calibratre BOARD_LOOPSPERMSEC. You simply use a stop
watch to measure the actual delay then adjust BOARD_LOOPSPERMSEC until
the actual delay is 100 seconds.
config DRAM_START

this may be SDRAM or SRAM or any other RAM technology that support
program execution.

this may be SDRAM or SRAM or any other RAM technology that support
program execution.

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"

Some configurations boot in FLASH but copy themselves entirely into
RAM for better performance.
