[PATCH] MAXQ port binutils-2_15


We at HCL Technologies Pvt. Ltd. Have ported binutils v1.5 for the MAXQ

MAXQ is a new high performance RISC architecture from Maxim Integrated
Products & Dallas Semiconductor.
The MAXQ RISC architecture has a new microcontroller core that combines
high performance and low power 
with a variety of complex analog functions.

The MAXQ can be seen as a MOVE driven architecture and the source and
destination operands for the
"MOVE" instruction are the basis for creating instructions and memory
accesses, and triggering hardware

	  0    Index Mod.  Immediate Data

Initially the MAXQ Arch. has two slightly different versions named
MAXQ10 and MAXQ20. The primary
difference between the MAXQ10 and MAXQ20 options is the standard width
of the working accumulators
 and supporting arithmetic logic unit (ALU).  The MAXQ10 supports 8-bit
(byte-wide) accumulators and 
ALU operations, while the MAXQ20 supports 16-bit (word-wide)
accumulators and ALU operations.

The MAXQ microcontroller uses Peripheral Registers to control and
monitor peripheral 
modules (like General Purpose I/O Module, UART, MAC etc.)

More Information about MAXQ

About MAXQ binutils v2.15 port

- The binutils contains support for both MAXQ10 and MAXQ20 versions of

- Apart from standard MAXQ Arch. binutils support the   MAXQ2000
variant. Which includes support for
  integrated, in-system-programmable flash memory and a   wide range of
peripherals including an LCD
 driver   supporting up  to x4 multiplexed displays. The MAXQ2000   is
ideally suited for battery-powered,
 portable applications such as blood glucose monitoring, medical
instrumentation, environmental data logging, and   industrial control.

Testing binutils for MAXQ

The testcases for the MAXQ arch. has been integrated into the DEJAGNU
which will be posted later on.

Configuring and Installing

While configuring the binutils source we need to specify the option
Go to the binutils sources and do:

 > configure --enable-bfd-assembler --target=maxq-coff
 > make
 > make install
