] fix monitor protection for CONFIG_MONITOR_IS_IN_RAM
For platforms with flash below ram addresses, the current check to activate monitor protection is wrong/insufficient. This patch fixes CONFIG_MONITOR_IS_IN_RAM for these systems by adding a check for this configuration. Signed-off-by: Wolfgang Wegner <w.wegner@astro-kom.de> Signed-off-by: Stefan Roese <sr@denx.de>
