/*
 *  XDM registers can be accessed using APB, ERI, or JTAG (via NAR).
 *  Address offsets for APB and ERI are the same, and for JTAG
 *  is different (due to the limited 7-bit NAR addressing).
 *
 *  Here, we first provide the constants as APB / ERI address offsets.
 *  This is necessary for assembler code (which accesses XDM via ERI),
 *  because complex conversion macros between the two address maps
 *  don't work in the assembler.
 *  Conversion macros are used to convert these to/from JTAG (NAR),
 *  addresses, for software using JTAG.
