[coreboot] Building AMD Persimmon in MinGW

[Wim Vervoorn]

Hello,

This is the fragment where it fails:

It seems that the call to regcomp is causing the issue.

I don't think this has anything to do with direct access to the
hardware. It seems to be some kind of pointer issue, the call seems to
access data it can't reach.


/***********************************************************************
*****
 * compile_reg_expr
 *
 * Compile a regular expression.
 
************************************************************************
****/
void compile_reg_expr(int cflags, const char *expr, regex_t *reg)
{
	static const size_t ERROR_BUF_SIZE = 256;
	char error_msg[ERROR_BUF_SIZE];
	int result;

-->>>>	if ((result = regcomp(reg, expr, cflags)) != 0) {  <<---------

		regerror(result, reg, error_msg, ERROR_BUF_SIZE);
		fprintf(stderr, "%s: %s\n", prog_name, error_msg);
		exit(1);
	}

	printf( "compile_reg_expr 3\n");

}


Regards,

Wim

During the handling of cmos.layout and cmos.settings (if present and
used).

We don't need any special hardware access for that and should not use
any such code while building coreboot.
One place to look at is the win32mmap implementation, which _is_ used.
