What is the reason why CONFIG_PCIE3 setups up the pci node called "pci0"? Is it because CONFIG_SYS_PCIE3_ADDR is the address of the pci0 node in the p2020ds device tree?

If so, why can't we do this is P2020DS.h:

#define CONFIG_SYS_PCIE1_ADDR (CONFIG_SYS_CCSRBAR+0x8000) /* pci0 */ #define CONFIG_SYS_PCIE2_ADDR (CONFIG_SYS_CCSRBAR+0x9000) /* pci1 */ #define CONFIG_SYS_PCIE3_ADDR (CONFIG_SYS_CCSRBAR+0xa000) /* pci2 */
