This can go into bootblock, not ramstage. We don't have any devices out in the field yet with locked R/O firmware.
make sense. may be finalize.c ?
Wouldn't it want to do this as soon as we come out of reset i.e. before any GPIOs are configured?
Something like bootblock_soc_early_init ?
We need to ensure that the early BARs are set up correctly before accessing these registers. I believe it gets set in bootblock_soc_early_init().

I believe it's p2sb_enable_bar()
