      drivers/char/tpm: Add new device driver to support IBM vTPM · 132f7629
      Ashley Lai 提交于
      This patch adds a new device driver to support IBM virtual TPM
      (vTPM) for PPC64.  IBM vTPM is supported through the adjunct
      partition with firmware release 740 or higher.  With vTPM
      support, each lpar is able to have its own vTPM without the
      physical TPM hardware.
      
      This driver provides TPM functionalities by communicating with
      the vTPM adjunct partition through Hypervisor calls (Hcalls)
      and Command/Response Queue (CRQ) commands.
