Subject: [PATCH v3 0/2] firmware: google: Expose coreboot tables and CBMEM
Date: Thu, 28 Nov 2019 13:50:49 +0100	[thread overview]
Message-ID: <20191128125100.14291-1-patrick.rudolph@9elements.com> (raw)

From: Patrick Rudolph <patrick.rudolph@9elements.com>

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

Changes in v3:
 - Use BIN_ATTR_RO
