Please help me with compiling the kernel for ML403

[Mohammad Sadegh Sadri]

Hi

It is some thing more than 2 weeks that I'm trying to compile the kernel for ML403. 
Posted to questions here, but unfortunately, didn't get any answer from the experts here.
I have tested every thing I knew ( with my limited knowledge ) and now, I really need your help.

I'm using the following set of tools:
EDK 8.2.02,  ( Latest )
ELDK 4.1 ( Latest )

-I want to compile the 2.6.20 kernel, downloaded from kernel.org

-As the first step, in EDK, I choose linux 2.6 in software platform generation settings,

-I generate the BSP. 

-In the generated BSP , I convert all of the 40x strings to 403, also I change the name of xparameters_ml40x to xparameters_ml403

-I copy the 2.6.20 kernel /eldk/ppc_4xx/usr/src/linux , and set all of the needed env variables for cross compile, and set the needed changes in the linux Makefile. ( ARCH and 
CROSS_COMPILE )

-I copy the entire BSP into the root of the linux kernel.

-I edit the linux/arch/ppc/Kconfig file, and add these lines into it:
config XILINX_OCP
	bool "Xilinx OCP"
	default y

config XILINX_TEMAC
	bool "Xilinx TEMAC"
	default y

config XILINX_SYSACE
	bool "Xilinx System ACE"
	default y

config XILINX_EDK
	bool "Xilinx EDK Support"
	default y

-In the linux folder I execute the cow.tcl script provided with the BSP from EDK ( I execute tclsh cow.tcl ) 

-I make a symbolic link , for config.h file, ( I go to linux/include/linux and then ln -s autoconf.h config.h )

-I begin the menuconfig and set all of the needed parameters

-Now, I begin the make process by simply typing : make

- I encounter the following error:
arch/ppc/platforms/4xx/virtex.c:20: error: array type has incomplete element type
arch/ppc/platforms/4xx/virtex.c:60: error: field name not in record or union initializer
arch/ppc/platforms/4xx/virtex.c:60: error: (near initialization for 'core_ocp')
make[1]: *** [arch/ppc/platforms/4xx/virtex.o] Error 1
make: *** [arch/ppc/platforms/4xx] Error 2

- I can prevent this error by commenting these lines of /arch/ppc/platforms/4xx/virtex.c file:
/* Have OCP take care of the serial ports. */
struct ocp_def core_ocp[] = {
#ifdef XPAR_UARTNS550_0_BASEADDR
	{ .vendor	= OCP_VENDOR_XILINX,
	  .function	= OCP_FUNC_16550,
	  .index	= 0,
	  .paddr	= XPAR_UARTNS550_0_BASEADDR,
	  .irq		= XPAR_INTC_0_UARTNS550_0_VEC_ID,
	  .pm		= OCP_CPM_NA
	},
#ifdef XPAR_UARTNS550_1_BASEADDR
	{ .vendor	= OCP_VENDOR_XILINX,
	  .function	= OCP_FUNC_16550,
	  .index	= 1,
	  .paddr	= XPAR_UARTNS550_1_BASEADDR,
	  .irq		= XPAR_INTC_0_UARTNS550_1_VEC_ID,
	  .pm		= OCP_CPM_NA
	},
#ifdef XPAR_UARTNS550_2_BASEADDR
	{ .vendor	= OCP_VENDOR_XILINX,
	  .function	= OCP_FUNC_16550,
	  .index	= 2,
	  .paddr	= XPAR_UARTNS550_2_BASEADDR,
	  .irq		= XPAR_INTC_0_UARTNS550_2_VEC_ID,
	  .pm		= OCP_CPM_NA
	},
#ifdef XPAR_UARTNS550_3_BASEADDR
	{ .vendor	= OCP_VENDOR_XILINX,
	  .function	= OCP_FUNC_16550,
	  .index	= 3,
	  .paddr	= XPAR_UARTNS550_3_BASEADDR,
	  .irq		= XPAR_INTC_0_UARTNS550_3_VEC_ID,
	  .pm		= OCP_CPM_NA
	},
#ifdef XPAR_UARTNS550_4_BASEADDR
#error Edit this file to add more devices.
#endif			/* 4 */
#endif			/* 3 */
#endif			/* 2 */
#endif			/* 1 */
#endif			/* 0 */
	{ .vendor	= OCP_VENDOR_INVALID
	}
};

- Instead of the ebove lines, I just put one simple line: ( I use uart lite and not the 16550 so there should be no problem commenting these lines? )
struct ocp_def * core_ocp;

- now, I begin the make process again, The make process goes ahead but after a long time it generates another error:
  GEN     .version
  CHK     include/linux/compile.h
  UPD     include/linux/compile.h
  CC      init/version.o

  LD      .tmp_vmlinux1

arch/ppc/syslib/built-in.o:: more undefined references to `ppc_sys_platform_devices' follow
make: *** [.tmp_vmlinux1] Error 1

- If I do not add the BSP files from EDK to my kernel and compile the kernel for ML403, every thing will be completely OK. ( But I want TEMAC )

- when I look in the original virtex.c file, I see that it has defined ppc_sys_platform_devices but when I look at the virtex.c generated by Xilinx, I see that it has a completely different structure, it has no definition of this variable. It is completely different from the original virtex.c

- I have tested the same things above, with different versions of 2.6 kernel, such as, 2.6.17.1 and 26-xilinx-devel ( which I download from montavista using git near two weeks ago ) , I also changed the version of eldk to 4.0 and to 3.5 ( with 3.5 I could not compile the kernel at all ) 

Any idea, Any suggestion and any thing which can help even a litte, is welcome, 
I really do not know what to do more.

Thanks.
