+/*
+Currently, ROM code reserves the first 8KB of RAM for its data/bss.
+The next 12KB or RAM is used for RAM software's literals and read-only data.
+After that comes 64KB reserved for RAM software's data and bss.
+Then 92KB of RAM is reserved for text (code).
+The last 8KB of RAM is reserved for ROM patches, customer DataSets,
+and RAM software expansion. (There is also some additional RAM between
+segments that can be used, if needed.)
+ ROM reserved: 0x00500000..0x00501fff
+ Literals: 0x00502000..0x00504fff
+ Data: 0x00505000..0x00514fff
+ Text: 0x00915000..0x0092bfff
+TBD: May want to use a 2-pass link approach in order to
+eliminate fixed boundaries. Support for physical addressing
+in Tensilica tools would be helpful, but it's not coming
+any time soon.
