[PATCH v4 0/6] 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() to fix sparse
__iomem issue, and finally simplify code. 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 v3:
 * Dropped last patch for resource reservation 
 * Pick up review tags on patch#1
 * Always unmap memory for table instead of keep it around

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
