+# This phone has 3 memory chip selects:
+#
+# nCS0: flash chip select 1
+# nCS1: RAM chip select
+# nCS3: flash chip select 2
+#
+# All 3 chip select lines go to the same physical IC, a RAM/flash MCP.
+# We set WS=4 for all 3 here, copying what OsmocomBB does.  The access
+# time listed in the datasheet is 70 ns for both RAM and flash, and per
+# my math setting WS=3 *might* work, but it could be marginal, so let's
+# play it safe for now.
