+         This option provides a means to manipulate Isolated Memory Regions.
+         IMRs are a set of registers that define read and write access masks
+         to prohibit certain system agents from accessing memory with 1 KiB
+         granularity.
+
+         IMRs make it possible to control read/write access to an address
+         by hardware agents inside the SoC. Read and write masks can be
+         defined for:
+               - eSRAM flush
+               - Dirty CPU snoop (write only)
+               - RMU access
+               - PCI Virtual Channel 0/Virtual Channel 1
+               - SMM mode
+               - Non SMM mode
+
+         Quark contains a set of eight IMR registers and makes use of those
+         registers during its bootup process.

+         If you are running on a Galileo/Quark say Y here.
