<title>DESCRIPTION</title>
<para>This manual page documents briefly the
<command>&dhpackage;</command> command.</para>
<para><command>&dhpackage;</command> is used to convert the contents
of a boot config table (BCT) used in NVIDIA Tegra devices, ready
to be further proceeded by <command>cbootimage</command> (1).
The BCT is usually placed in the first bytes of the storage device
and can be extracted using <command>tegrarcm</command>(1).</para>
<para>
The BCT is a data structure that provides basic initialization
parameters, and defines the bootloader to execute.</para>
<para>The BCT contains: <itemizedlist>
<listitem><para>Header information, such as cryptographic validation
hashes and size information.</para></listitem>
<listitem><para>Boot memory configuration. This allows the boot memory controller
to be programmed optimally, in order to read the bootloader.</para></listitem>
<listitem><para>SDRAM controller configuration. This allows the SDRAM controller
to be programmed, and hence external SDRAM accessed.</para></listitem>
<listitem><para>A bad block table.</para></listitem>
<listitem><para>Information about the bootloader to execute.</para></listitem>
<listitem><para>A "customer data" area, which may be used to store arbitrary customer- or
device-software-specific data. This area includes the ODMDATA.</para></listitem>
</itemizedlist></para>
