## Configuration
-To use `phosphor-ipmi-flash` a platform must provide a configuration. A
-platform can configure multiple interfaces, such as both lpc and pci. However,
-a platform should only configure either static layout updates, or ubi. If
-enabling lpc, the platform must specify either aspeed or nuvoton.
-
-The following are the two primary configuration options, which control how the
-update is treated.
-
-Option | Meaning
------------------------- | -------
-`--enable-static-layout` | Enable treating the update as a static layout update.
-`--enable-tarball-ubi` | Enable treating the update as a tarball for UBI update.
-
-The following are configuration options for how the host and BMC are meant to
-transfer the data. By default, the data-in-IPMI mechanism is enabled.
-
-There are two configurable data transport mechanisms, either staging the bytes
-via the LPC memory region, or the PCI-to-AHB memory region. Because there is
-only one `MAPPED_ADDRESS` variable at present, a platform should only configure
-one. The platform's device-tree may have the region locked to a specific
-driver (lpc-aspeed-ctrl), preventing the region from other use.
-
-***NOTE:*** It will likely be possible to configure both in the near future.
-
-Variable | Default | Meaning
---------------------- | ------- | -------
-`MAPPED_ADDRESS` | 0 | The address used for mapping P2A or LPC into the BMC's memory-space.
-
-Option | Meaning
---------------------- | -------
-`--enable-pci-bridge` | Enable the PCI-to-AHB transport option.
-`--enable-lpc-bridge` | Enable the LPC-to-AHB transport option.
-
-If a platform enables lpc as the transport mechanism, a specific vendor must be
-selected via the following configuration option. Currently, only two are
-supported.
-
-Option | Meaning
----------------------- | -------
-`--enable-aspeed-lpc` | Use with ASPEED parts.
-`--enable-nuvoton-lpc` | Use with Nuvoton parts.
-
-### Internal Configuration Details
-
-The following variables can be set to whatever you wish, however they have
-usable default values.
-
-Variable | Default | Meaning
----------------------------- | -------------------------- | -------------------------------------------------------------------------
-`STATIC_HANDLER_STAGED_NAME` | `/run/initramfs/bmc-image` | The filename where to write the staged firmware image for static updates.
-`TARBALL_STAGED_NAME` | `/tmp/image-update.tar` | The filename where to write the UBI update tarball.
-`HASH_FILENAME` | `/tmp/bmc.sig` | The file to use for the hash provided.
