The RCW source is set by appropriate DIP-switches: - 16-bit NOR Flash / PROMJet - QIXIS 8-bit NOR Flash Emulator - 8-bit NAND Flash - 24-bit SPI Flash - Long address I2C EEPROM - Available debug interfaces are: - On-board eCWTAP controller with ETH and USB I/F - JTAG/COP 16-pin header for any external TAP controller - External JTAG source over AMC to support B2B configuration - 70-pin Aurora debug connector - QIXIS (FPGA) logic: - 2 KB internal memory space including - IDT840NT4 clock synthesizer provides B4860 essential clocks : SYSCLK, DDRCLK1, 2 and RTCCLK. - Two 8T49N222A SerDes ref clock devices support two SerDes port clocks - total four refclk, including CPRI clock scheme Signed-off-by: York Sun <yorksun@freescale.com> Signed-off-by: Prabhakar Kushwaha <prabhakar@freescale.com> Signed-off-by: Shaveta Leekha <shaveta@freescale.com> Signed-off-by: Priyanka Jain <Priyanka.Jain@freescale.com> Signed-off-by: Poonam Aggrwal <poonam.aggrwal@freescale.com> Signed-off-by: Roy Zang <tie-fei.zang@freescale.com> Signed-off-by: Sandeep Singh <Sandeep@freescale.com> Signed-off-by: Andy Fleming <afleming@freescale.com>
