[PATCH v3 0/7] firmware: coreboot: Fix probe and simplify code

[Stephen Boyd]

This series reworks the coreboot firmware driver a bit to fix some bugs
and then simplify the code by changing the design to get rid of the
different platform drivers, remap memory with memremap(), and use devm
to simplify error paths. There's some risk in changing to memremap() but
I think that should work out alright. It will either return memory
directly, or fallback to ioremap_cache() as has been done before.

Changes from v2:
 * A bunch more patches
 * Fix iounmap missing on error path
 * Fix bus getting unregistered on driver unbind and never registered
   again
 * Request exclusive access to table region
 * Pull out table signature check to driver probe

Changes from v1:
 * Split out fixlet for DT based driver from platform driver change
