Details:

As documented in

http://www.nongnu.org/avr-libc/user-manual/group__avr__io.html

XRAMEND is supposed to be the same as RAMEND for devices without
XRAM (except for devices that do not have RAM at all), since it
is supposed to be the last possible RAM location.  Other files
and users might rely on this.

The following recent header files erroneously set XRAMEND to 0:

io90pwm216.h    #define XRAMEND        0
io90pwm2b.h     #define XRAMEND        0x00
io90pwm316.h    #define XRAMEND        0
io90pwm3b.h     #define XRAMEND        0x00
iom1284p.h      #define XRAMEND      0
iom168p.h       #define XRAMEND      0
iom328p.h       #define XRAMEND      0
iom32hvb.h      #define XRAMEND      0
iom48p.h        #define XRAMEND      0
iom88p.h        #define XRAMEND      0
iotn48.h        #define XRAMEND               0x00
iotn88.h        #define XRAMEND               0x00
