.SH NAME
efi_crc32 \- EFI version of crc32 function
.SH SYNOPSIS
"SYNOPSIS"

\fB
.sp
u32 efi_crc32  (const void * \fIbuf\fB, unsigned long \fIlen\fB);
\fR
.SH "ARGUMENTS"
.TP
\fB\fIbuf\fB\fR
buffer to calculate crc32 of
\fIlen\fR - length of buf
.TP
\fB\fIlen\fB\fR
-- undescribed --
.SH "DESCRIPTION"
.PP
Returns EFI-style CRC32 value for \fIbuf\fR
.PP
This function uses the little endian Ethernet polynomial
but seeds the function with ~0, and xor's with ~0 at the end.
Note, the EFI Specification, v1.02, has a reference to
Dr. Dobbs Journal, May 1994 (actually it's in May 1992).
