Public bug reported:
SRU Justification:
[Impact]
Support the I2C lock mechanism, otherwise there could be unexpected
behavior when the i2c driver is accessed by several entities like the
linux driver, ATF driver and UEFI driver.
[Fix]
* Support lock and unlock
* replace ioremap_nocache with ioremap
[Test Case]
* Make sure the i2c-mlxbf.c driver is loaded and /dev/i2c-1 is created
* check that ipmitool from the BF->BMC and from the BMC->BF work (this only
applies on boards with a BMC of course)
[Regression Potential]
Any of the test cases above could be impacted due to these changes.
