This patch removes the duplicted implementations of the pci_target_init() function by introducing a weak default function for it. This weak default has a different implementation for 440EP(x)/GR(x) PPC's. It can be overridden by a board specific version (e.g. PMC440, korat).
Signed-off-by: Stefan Roese sr@denx.de --- Changes in v2: - Fix comments (Matthias) - Used CONFIG_SYS_PCI_SUBSYS_ID_MONARCH instead of hardcoded number in PMC440 header (Matthias)
