NAME: u241mon.c
DESC: u241mon 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.
