Note that the debug version of the FSP is bigger in size. If this version
is used, CONFIG_FSP_ADDR needs to be configured to 0xfffb0000 instead of
the default value 0xfffc0000.
+
+If you want to change CONFIG_TEXT_BASE from the current value of ffe00000
+you need to check a few other things. CONFIG_SYS_MONITOR_BASE should
+automatically update to be the same as CONFIG_TEXT_BASE but
+CONFIG_SYS_MONITOR_LEN may need to be adjusted too. It must cover the space
+from the start of U-Boot to the end of the RAM, since the 16-bit boot needs to
+be able to jump to U-Boot. See the end of arch/x86/lib/fsp1/fsp_car.S which
+has these values.
+
+Also check the MRC cache address in the devicetree ("rw-mrc-cache"). It must
+not overlap with U-Boot.
