Hello All,

As per Wolfgang's suggestion I am trying first to use existing DoC driver.

This is for a custom board based on ADI's Blackfin BF537 CPU.

I am having problem with undefined EIEIO, which is specific to PPC arch. The blackfin asm/io.h has nothing about EIEIO

common/libcommon.a(cmd_doc.o): In function `DoC_WriteBuf':/home/mark/development/u-boot/common/cmd_doc.c:598: undefined reference to `eieio'

/home/mark/development/u-boot/common/cmd_doc.c:601: undefined reference to `eieio'

common/libcommon.a(cmd_doc.o): In function `DoC_SelectFloor':/home/mark/development/u-boot/common/cmd_doc.c:637: undefined reference to `eieio'

common/libcommon.a(cmd_doc.o): In function `DoC_SelectChip':/home/mark/development/u-boot/common/cmd_doc.c:614: undefined reference to `eieio'

/home/mark/development/u-boot/common/cmd_doc.c:618: undefined reference to `eieio'

common/libcommon.a(cmd_doc.o):/home/mark/development/u-boot/common/cmd_doc.c:622: more undefined references to `eieio'

followmake: *** [u-boot] Error 1

I am wondering if anyone has DoC working on platform other than PPC?

Any suggestions?

Regards,

Mark

Hm... why don't you simply use the existing DoC support in U-Boot?
