Support for ADSP-BF60x silicon revision 0.1

The CCES 1.0.2.0 toolchain provides support for silicon revision 0.1 of the ADSP-BF60x

part family. This support includes a change to the startup code that is necessary to

avoid parity error exceptions seen when running on revision 0.1 hardware. This change

is incorporated automatically when the generated startup code is regenerated and is in

the various pre-built default basiccrt crt.doj files. If you are using a custom startup

source or have disabled regeneration of the generated files you will need to add the

following BITSET instruction before accessing the ITEST_COMMAND or

DTEST_COMMAND registers:

#include <sys/platform.h>

BITSET(R7, BITP_ITEST_COMMAND_PARCTL);

For example:

// Zero the ITEST_COMMAND and DTEST_COMMAND registers

// (in case they have unintialized values in them that

// cause a write somewhere when we enable cache).

BITSET(R7, BITP_ITEST_COMMAND_PARCTL);

I0.L = LO(ITEST_COMMAND);

I0.H = HI(ITEST_COMMAND);

I1.L = LO(DTEST_COMMAND);

I1.H = HI(DTEST_COMMAND);

[I0] = R7;

[I1] = R7;

CSYNC;

Note that any executable built with CCES 1.0.0.x or 1.0.1.x will need to be re-linked with

an updated crt object before being used with 0.1 hardware.
