Subject: [PATCH 0/2] firmware: google: Expose coreboot tables and CBMEM

From: Patrick Rudolph <[email protected]>

As user land tools currently use /dev/mem to access coreboot tables and
CBMEM, provide a better way by using read-only sysfs attributes.

Unconditionally expose all tables and buffers making future changes in
coreboot possible without modifying a kernel driver.

Changes in v2:
- Add ABI documentation
- Add 0x prefix on hex values
- Remove wrong ioremap hint as found by CI

I think you forgot to put "v2" in the [PATCH] area of the subject lines
:(
