The macro is already defined in TFA defconfig, also define in qspi defconfig.

ENV_ADDR value is QSPI_BASE + ENV_OFFSET.
In case of TFA boot(*_tfa_defconfig), ENV_ADDR is 0x40500000 i.e 0x40000000 + 0x500000
And in qspi (*qspi_defconfig), ENV_ADDR is 0x40300000 i.e 0x40000000 + 0x300000.
This helps in picking env from flash before DDR.

Please see above for more clarification.

I have already mentioned that changes are done in defconfigs. Could you please mention what more info needs to be added/changed?
