firmware: google memconsole: Remove useless submenu in Kconfig This patch removes the "Google Firmware Drivers" menu containing a menuconfig entry with the exact same name. The menuconfig is now directly under the "Firmware Drivers" entry. Signed-off-by: Thierry Escande <thierry.escande@collabora.com> Signed-off-by: Greg Kroah-Hartman <gregkh@linuxfoundation.org>

help
These firmware drivers are used by Google's servers. They are
only useful if you are working directly on one of their
proprietary servers. If in doubt, say "N".

driver: Google EFI SMI The "gsmi" driver bridges userland with firmware specific routines for accessing hardware. Currently, this driver only supports NVRAM and eventlog information. Deprecated functions have been removed from the driver, though their op-codes are left in place so that they are not re-used. This driver works by trampolining into the firmware via the smi_command outlined in the FADT table. Three protocols are used due to various limitations over time, but all are included herein. This driver should only ever load on Google boards, identified by either a "Google, Inc." board vendor string in DMI, or "GOOGLE" in the OEM strings of the FADT ACPI table. This logic happens in gsmi_system_valid().

firmware/google: drop 'select EFI' to avoid recursive dependency The GOOGLE_SMI Kconfig symbol depends on DMI and selects EFI. This causes problems on other archs when introducing DMI support that depends on EFI, as it results in a recursive dependency: arch/arm/Kconfig:1845:error: recursive dependency detected! arch/arm/Kconfig:1845: symbol DMI depends on EFI Fix by changing the 'select EFI' to a 'depends on EFI'.

Say Y here if you want to enable SMI callbacks for Google
platforms. This provides an interface for writing to and
clearing the EFI event log and reading and writing NVRAM
variables.
driver: Google Memory Console This patch introduces the 'memconsole' driver. Our firmware gives us access to an in-memory log of the firmware's output. This gives us visibility in a data-center of headless machines as to what the firmware is doing. The memory console is found by the driver by finding a header block in the EBDA. The buffer is then copied out, and is exported to userland in the file /sys/firmware/log.

firmware: google memconsole: Move specific EBDA parts This patch splits memconsole.c in 2 parts. One containing the architecture-independent part and the other one containing the EBDA specific part. This prepares the integration of coreboot support for the memconsole. The memconsole driver is now named as memconsole-x86-legacy.

This option enables the kernel to search for a firmware log in
the EBDA on Google servers. If found, this log is exported to
userland in the file /sys/firmware/log.
