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
