=================================================

Hardware/Software Environment
-----------------------------------------------------------
A) Sometimes, if you use s3c2440_camif.o as a moduels
"consistent_alloc" of memory allocation will be failed.
	you can try as the followings.
	1. put s3c2440_camif.o into zImage (using built-in)
    2. remove the unnecessary modules 

B) make sure that your board support 24Mhz Camera clock (using a internal clock)
C) make sure that S3C2440 Evalution Board is above Rev 0.17
D) make sure that you jummper setting (J12 --5 voltage )
E) make sure that your CAMERA modules C3188A  (using a internel clock , do not use extenal clock 12MHz)
                have no OSC and JP1 connected.

How to install
------------------------------------------------------------
1. make sure that
  target_B'd SHELL> free 
           total    used   free   shared    buffers
    mem:   62804    42296   20508     0       8748 
   Swap:       0        0       0
  Total:   62804    42296   20508
 
 --> " Free memory " must be above the 10Mbyte at least and  
    if there were not enough for S3C2440_camif.o, it is recommended that you
    use built-in kernel including camera modules.

2. Supposed that 
		you must do the followings
		 A) make menuconfig
		 B) make dep
		 B) make zImage

3. open "Makefile"

4. set KERNEL_DIR= "your kernel path" 

5. type "make"
	in order to make camera D/D module

6. to install kernel modules

  SHELL> insmod videodevX.o
  SHELL> insmod s3c2440_camif.o
  SHELL> insmod smdk2440_ov7620.o

7.  In order to execute camera test application
   cd v4l2_testsuite
