Dear Macpaul Lin,

Although most IDE controller is designed to be connected to PCI bridge, there are still some IDE controller support AHB interface for SoC design.
The driver implementation of these IDE-AHB controllers differ from other IDE-PCI controller, some additional registers and commands access is required during CMD/DATA I/O. Hence a configuration "CONFIG_IDE_AHB" in cmd_ide.c is required to be defined to support these kinds of SoC controllers. Such as Faraday's FTIDE020 series and Global Unichip's UINF-0301.
...
extern void ide_write_register(int, unsigned int, unsigned char);
...
- extern unsigned char ide_read_register(int, unsigned int);
Etc. Please move all such prototype decarations to an appropriate header file and get rid of these "extern"s here.
Thanks.
Best regards,
