[U-Boot-Users] porting kernel driver to u-boot
Good Evening, I am looking for some pointers on how to port Linux kernel drivers to u-Boot. Specifically, Diskonchip from Sandisk/m-systems. I can not find any instructions nor tips on where to start. I started looking at drivers for the same devices but this is very slow process.
Any suggestions will be greatly appreciated. Thanks, Mark

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

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

mtd/doc2000.h should probably be changed to use sync() (assuming that's a safe eieio replacement for your platform).
