− * Our loadagent will always be loaded into Calypso targets by the on-chip
+
− * boot ROM operating in the UART download mode.  The lowest IRAM address
+
− * at which we can load our code is 0x800750; somewhat lower at 0x800518
+
− * the boot ROM downloader has a few variables which may have been intended
+
− * to be private to the boot ROM, but which are useful to us.  For example,
+
− * by looking at these variables, we can see which of the two UARTs was
+
− * used to feed our code to the boot ROM, and use the same UART for
+
− * subsequent communication - without building multiple versions of our
+
− * loadagent or resorting to other ugliness.
+
− *
+
− * This header file defines the layout of the IRAM structure in question,
+
− * based on the disassembly of the boot ROM.
