20 * File: baseband.c
21 *
22 * Purpose: Implement functions to access baseband
23 *
24 * Author: Kyle Hsu
25 *
26 * Date: Aug.22, 2002
27 *
28 * Functions:
29 * BBuGetFrameTime - Calculate data frame transmitting time
30 * BBvCaculateParameter - Caculate PhyLength, PhyService and Phy Signal
31 * parameter for baseband Tx
32 * BBbReadEmbedded - Embedded read baseband register via MAC
33 * BBbWriteEmbedded - Embedded write baseband register via MAC
34 * BBbVT3253Init - VIA VT3253 baseband chip init code
35 *
36 * Revision History:
37 * 06-10-2003 Bryan YC Fan: Re-write codes to support VT3253 spec.
38 * 08-07-2003 Bryan YC Fan: Add MAXIM2827/2825 and RFMD2959 support.
39 * 08-26-2003 Kyle Hsu : Modify BBuGetFrameTime() and BBvCalculateParameter().
40 * cancel the setting of MAC_REG_SOFTPWRCTL on BBbVT3253Init().
41 * Add the comments.
42 * 09-01-2003 Bryan YC Fan: RF & BB tables updated.
43 * Modified BBvLoopbackOn & BBvLoopbackOff().
