Christopher Bostic	ac0385d9f6	drivers/fsi: Add GPIO based FSI master ... Implement a FSI master using GPIO. Will generate FSI protocol for read and write commands to particular addresses. Sends master command and waits for and decodes a slave response. Includes changes from Edward A. James <eajames@us.ibm.com> and Jeremy Kerr <jk@ozlabs.org>. Signed-off-by: Edward A.
