2011-12-09firmware: google: fix gsmi.c build warningMaxin B. John
Use min_t() macro instead of min() to fix a build warning: CC drivers/firmware/google/gsmi.o drivers/firmware/google/gsmi.c: In function ‘gsmi_get_variable’: drivers/firmware/google/gsmi.c:348: warning: comparison of distinct pointer types lacks a cast Signed-off-by: Maxin B.

2011-10-31drivers/firmware: Add module.h to google/gsmi.cPaul Gortmaker
This file really needs the full module.h header file present, but was just getting it implicitly before. Fix it up in advance so we avoid build failures once the cleanup commit is present. Signed-off-by: Paul Gortmaker <paul.gortmaker@windriver.com>

Fixes a build warning: drivers/firmware/google/gsmi.c:473: warning: initialization from incompatible pointer type Signed-off-by: Randy Dunlap <rdunlap@xenotime.net> Cc: Mike Waychison <mikew@google.com> Signed-off-by: Greg Kroah-Hartman <gregkh@suse.de>
2011-07-01firmware: gsmi: remove sysfs entries when unload the moduleAxel Lin
This patch removes sysfs entries in gsmi_exit() and gsmi_init() error path. Also move the driver successfully loaded message to the end of gsmi_init() and return proper error if register_efivars() fails. Signed-off-by: Axel Lin <axel.lin@gmail.com> Signed-off-by: Greg Kroah-Hartman <gregkh@suse.de>
2011-04-29driver: Google EFI SMIMike Waychison
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().
