Hi, we add a new feature for ixp25 , add PCI support for ixp425 ,
There is a problem with your patch. As is, it generates a couple of warnings like these:
-> MAKEALL ixdp425 Configuring for ixdp425 board... pci_indirect.c: In function `indirect_read_config_byte': pci_indirect.c:85: warning: implicit declaration of function `out_le32' pci_indirect.c:85: warning: implicit declaration of function `in_8' pci_indirect.c: In function `indirect_read_config_word': pci_indirect.c:86: warning: implicit declaration of function `in_le16' pci_indirect.c: In function `indirect_read_config_dword': pci_indirect.c:87: warning: implicit declaration of function `in_le32' pci_indirect.c: In function `indirect_write_config_byte': pci_indirect.c:93: warning: implicit declaration of function `out_8' pci_indirect.c: In function `indirect_write_config_word': pci_indirect.c:94: warning: implicit declaration of function `out_le16'
If I copy the prototypes of your implementation from cpu/ixp/pci.c I get different warnings:
-> MAKEALL ixdp425 Configuring for ixdp425 board... pci_indirect.c: In function `indirect_read_config_byte': pci_indirect.c:94: warning: passing arg 1 of `in_8' from incompatible pointer type pci_indirect.c: In function `indirect_read_config_word': pci_indirect.c:95: warning: passing arg 1 of `in_le16' from incompatible pointer type pci_indirect.c: In function `indirect_write_config_byte': pci_indirect.c:102: warning: passing arg 1 of `out_8' from incompatible pointer type pci_indirect.c: In function `indirect_write_config_word': pci_indirect.c:103: warning: passing arg 1 of `out_le16' from incompatible pointer type
Checking your code in cpu/ixp/pci.c I see:
void out_8 (volatile unsigned *addr, char val) ... *addr = val; ... void out_le16 (volatile unsigned *addr, unsigned short val) ... *addr = cpu_to_le16 (val);
etc.
Are you sure that all these "addr" pointers are really pointers to 32 bit objects?
Best regards,
