-WHAT ARE THESE FILES:
-
-These files contain MPC8240 (Kahlua) DMA controller
-driver routines. The driver routines are not
-written for any specific operating system.
-They serves the purpose of code sample, and
-jump-start for using the MPC8240 DMA controller.
-
-For the reason of correctness of C language
-syntax, these files are compiled by Metaware
-C compiler and assembler.
-
-ENDIAN NOTATION:
-
-The algorithm is designed for big-endian mode,
-software is responsible for byte swapping.
-
-USAGE:
-
-1. The host system that is running on MPC8240
-   or using MPC8240 as I/O device shall link
-   the files listed here. The memory location
-   of driver routines shall take into account of
-   that driver routines need to run in supervisor
-   mode and they process DMA controller interrupt.
-
-2. The host system is responsible for configuring
-   the MPC8240 including Embedded Utilities Memory
-   Block. Since the DMA controller on MPC8240 can
-   be accessed by either local 603e core or the host
-   that MPC8240 serves as I/O processor through host
-   PCI configuration, it is important that the local
-   processor uses EUMBBAR to access its local DMA
-   controller while the PCI master uses I/O
-   processor's PCSRBAR to access the DMA controller
-   on I/O device.
-
-   To qualify whether is EUMBBAR or PCSRBAR, one
-   additional parameter is requied from the host
-   system, LOCAL or REMOTE so that the base value
-   can be correctly interpreted.
-
-3. If the host system is also using the EPIC unit
-   on MPC8240, the system can register the
-   DMA_ISR with the EPIC including other
-   desired resources.
-
-   If the host system does not using the EPIC unit
-   on MPC8240, DMA_ISR function can be called for
-   each desired time interval.
-
-   In both cases, the host system is free to
-   provide its own interrupt service routine.
-
-4. To start a direct mode DMA transaction,
-   use DMA_Bld_Curr with the start parameter
-   set to 1.
-
-   To start a chaining mode DMA transaction,
-   the application shall build descriptors
-   in memory first, next, use DMA_Bld_Desp
-   with the start parameter set to 1.
-
-5. DMA_Start function clears, then sets the CS
-   bit of DMA mode register.
-
-   DMA_Halt function clears the CS bit of DMA
-   mode register.
-
-   These functions can be used to start and
-   halt the DMA transaction.
-
-   If the chaining descriptors has been
-   modified since the last time a DMA
-   transaction started, use DMA_Chn_Cnt
-   function to let DMA controller process
-   the modified descriptor chain without
-   stopping or disturbing the current DMA
-   transaction.
-
-   It is the host system's responsibility of
-   setting up the correct DMA transfer mode
-   and pass the correct memory address parameters.
-
-6. It is the host system's responsibility of
-   queueing the DMA I/O request. The host
-   system can call the DMA_ISR with its own
-   desired interrupt service subroutines to
-   handle each individual interrupt and queued
-   DMA I/O requests.
-
-7. The DMA driver routines contains a set
-   of utilities, Set and Get, for host system
-   to query and modify the desired DMA registers.

+ *  Please rememeber that unless there is a endpoint plugged in to root port it

+ *
+ *  In this release of software all the PCI-E ports are configured as either
+ *  endpoint or rootpoint.In future we will have support for selective ports
+ *  setup as endpoint and root point in single board.
+ *
+ *  Once your board came up as root point , you can verify by reading
+ *  /proc/bus/pci/devices. Where you can see the configuration registers
+ *  of end point device attached to the port.
+ *
+ *  Enpoint cofiguration can be verified by connecting Yucca board to any
+ *  host or another yucca board. Then try to scan the device. In case of
+ *  linux use "lspci" or appripriate os command.
+ *
+ *  How do I verify the inbound and out bound windows ?(yucca to yucca)
+ *  in this configuration inbound and outbound windows are setup to access
+ *  sram memroy area. SRAM is at 0x4 0000 0000 , on PLB bus. This address
+ *  is mapped at 0x90000000. From u-boot prompt write data 0xb000 0000,
+ *  This is waere your POM(PLB out bound memory window) mapped. then
+ *  read the data from other yucca board's u-boot prompt at address
+ *  0x9000 0000(SRAM). Data should match.
+ *  In case of inbound , write data to u-boot command prompt at 0xb000 0000
+ *  which is mapped to 0x4 0000 0000. Now on rootpoint yucca u-boot prompt check
