利用PC的并口做的JTAG接口

/********************************************************************************** 
 The SJF is written by analyzing ezTAG program, which was written by Jaewook Cheong,
 SEC S/W Centor. 
 Special thanks to Jaewook Cheong and Dale Roberts(the author of GIVEIO.sys)

 In SJF, the following feature is updated from ezTAG
 1. The structure of JTAG functions is changed for speed-up.
 2. The indexs of the pins become coherent with the BSDL file.
 3. SAMPLE/PRELOAD is used for initializing outCellValue[].
 4. The array size error is fixed(S3C2410_MAX_CELLS -> S3C2410_MAX_CELL_INDEX+2)
 5. The array was not followed by '\0', which is fixed.
 6. JTAG_ID reading error is fixed.
 7. Support K9S1208 SMD card for the SMDK2410 board.
 8. The programming speed is enhanced.
