Could somebody tell me what's the reasoning behing this
Quote from the description of strataflash CDL option
CYGOPT_DEVS_FLASH_STRATA_NOT_IN_RAM
"Rarely, it is useful to disable the request that flash driver code be
copied to separate RAM for execution. This option lets you do that.It
should only be controlled by redboot_XXX.ecm config files, for building
different varieties of RedBoot.
NEVER disable this option for ROM startup code, which executes in place
from Flash: the build will not work."
is there any reason why strataflash cannot use the section (".2ram")
approach for some targets?
thanks
Jani

Only that it vastly predates the ".2ram" strategy and there was never
any time (or compunction) to change it. Feel free to make these changes
and submit a patch.
