Dear Kumar Gala,

This doesn't seem to be the case in U-Boot; here we see:

#define CONFIG_SYS_PCIE3_ADDR           (CONFIG_SYS_CCSRBAR+0x8000)
#define CONFIG_SYS_PCIE2_ADDR           (CONFIG_SYS_CCSRBAR+0x9000)
#define CONFIG_SYS_PCIE1_ADDR           (CONFIG_SYS_CCSRBAR+0xa000)

i. e. the highest number is at the lowest address??



Best regards,

Wolfgang Denk
