[coreboot-gerrit] Change in coreboot[master]: RFC: soc/amd/picasso: Enable paging for boot

[Raul Rangel (Code Review)]

Hello build bot (Jenkins), Patrick Georgi, Martin Roth, Furquan Shaikh,

I'd like you to reexamine a change. Please visit

https://review.coreboot.org/c/coreboot/+/42889

to look at the new patch set (#3).

Change subject: RFC: soc/amd/picasso: Enable paging for boot
......................................................................

RFC: soc/amd/picasso: Enable paging for boot

This is WIP because I think we should dynamically map the 0-4KiB page
when we need to write to that range. Otherwise dereferencing a null
pointer is valid.

BUG=b:159081993
TEST=Boot trembyle to the OS.
