/****************************************************************
 NAME: u2440mon.c
 DESC: u2440mon entry point,menu,download
 HISTORY:
 Mar.25.2002:purnnamu: S3C2400X profile.c is ported for S3C2410X.
 Mar.27.2002:purnnamu: DMA is enabled.
 Apr.01.2002:purnnamu: isDownloadReady flag is added.
 Apr.10.2002:purnnamu: - Selecting menu is available in the waiting loop. 
                         So, isDownloadReady flag gets not needed
                       - UART ch.1 can be selected for the console.
 Aug.20.2002:purnnamu: revision number change 0.2 -> R1.1       
 Sep.03.2002:purnnamu: To remove the power noise in the USB signal, the unused CLKOUT0,1 is disabled.
