some problems on the SystemACE driver.

[Ming Liu]

Dear Ameet,
Sorry to bother you again but I am totally confused on the systemACE 
driver. First let me show you the problem.

1. I downloaded the linux kernel of 2.6.17.1, also the patch for SystemACE 
driver. Applied the patch to the kernel. Replaced the xparameters_ml403.h 
with the generated file xparameters_ml300.h from Xilinx EDK. Make 
menuconfig, make dep and make zImage. Then the error shows like this:

drivers/block/xilinx_sysace/xsysace.c:120:6: warning: 
"XPAR_XSYSACE_MEM_WIDTH" is not defined
drivers/block/xilinx_sysace/xsysace.c: In function `XSysAce_LookupConfig':
drivers/block/xilinx_sysace/xsysace.c:366: error: 
`XPAR_XSYSACE_NUM_INSTANCES' undeclared (first use in this function)
drivers/block/xilinx_sysace/xsysace.c:366: error: (Each undeclared 
identifier is reported only once
drivers/block/xilinx_sysace/xsysace.c:366: error: for each function it 
appears in.)
make[3]: *** [drivers/block/xilinx_sysace/xsysace.o] Error 1
make[2]: *** [drivers/block/xilinx_sysace] Error 2
make[1]: *** [drivers/block] Error 2
make: *** [drivers] Error 2

I think this is because of the no inclusion of the xparameters header file. 
So I change #include "xparameters.h" into  #include " 
/home/mingliu/linux-2.6.17.1/arch/ppc/platforms/4xx/xparameters/xparameters.h" 
in the files of xsysace.c and xsysace_g.c, using the full address to 
specify the header file. In fact, this is not a serious problem and it 
often happens. But, after the modification, another problem happened: 

  GEN     .version
  CHK     include/linux/compile.h
  UPD     include/linux/compile.h
  CC      init/version.o

: undefined reference to `XAssert'
drivers/built-in.o(.text+0x22cea): In function `XSysAce_Initialize':
: undefined reference to `XAssertStatus'

......( a long information to say that undefined reference to the XAssert 
things.)

Also, I tried this in the kernel 2.6.16-rc5. (In fact I prefer this version 
because the temac driver is for this version. ) The same problem happened. 
I checked the source code. The problem happened in the file 
driver/block/xilinx_sysace/adapter.c, etc. Also, the XAssert things are 
defined in the file arch/ppc/platforms/4xx/xilinx_ocp/xbasic_types.c. (In 
2.6.16 kernel, it is also defined in driver/xilinx_edk/xbasic_types.c. 
There are two copies of this file. ) I think the problem is, the systemACE 
files cannot link together with the xbasic_types.c file. 

I heard that you have tested this driver. Have you got this problem? Why 
there are so many strange problems for me while you have tested without 
problem? Without the CF card, I cannot try the Temac driver and my work is 
totally blocked. So I have to ask for your suggestion. Really anxious for 
your useful guidance. Thanks a lot!!!!!!

Regards
Ming
