- Subject: [PATCH 17/51] mb/dell: Add Latitude E6230 (Ivy Bridge)
- This was adapted from CB:22693 from Iru Cai, which was based on
- autoport. I do not physically have this system. Someone with physical
- access to an E6230 running version A11 of the vendor firmware sent me
- the VBT after running the command `intelvbttool --inlegacy --outvbt
- data.vbt`. This new version of the port has not yet been tested.
- The EC is the SMSC MEC5055, which seems to be compatible with the
- existing MEC5035 code. As with the other Dell systems with this EC, this
- board is assumed to be internally flashable using an EC command that
- tells it to pull the FDO pin low on the next boot, which also tells the
- vendor firmware to disable all write protections to the flash [1].
