   <b>Building from source:</b>
   At this moment, the kernel has to be in the FAT boot partition, not the
   root of the file system like other OpenBSD platforms, and this kernel
   must be in a format required by the U-Boot boot loader.
   So, after building your kernel, you must go through some special steps:
   
   <blockquote><pre>
   # <b>config GENERIC</b>
   # <b>cd ../compile/GENERIC</b>
   # <b>make clean; make</b>
   # <b>make bsd.OMAP.umg</b>
   # <b>mount /dev/sd0i /mnt</b>    <i># assuming your FAT partition is 'i'</i>
   # <b>cp bsd.OMAP.umg /mnt/bsd.umg</b>
   </pre></blockquote>
   
   <b>No real time clock:</b> Many of the armv7 devices do not have a
   battery backed real time clock.
   For this reason, using the "-s" option of
   <a href="faq/faq6.html#OpenNTPD">OpenNTPD</a> may be desirable.
   
   <p>
   <b>Distribution kernels must be converted before use:</b>
   The distribution kernels are standard kernels, which can be used
   for the <tt>-N</tt> option of
   <a href="http://man.openbsd.org/?query=ps">ps(1)</a>,
   <a href="http://man.openbsd.org/?query=vmstat">vmstat(8)</a>,
   <a href="http://man.openbsd.org/?query=dmesg">dmesg(8)</a>,
   <a href="http://man.openbsd.org/?query=iostat">iostat(8)</a>
   and similar applications, but cannot be booted directly by the U-Boot
   bootloader used on this platform.
   
   This can be done using
   <a href="http://man.openbsd.org/?query=mkuboot">mkuboot(8)</a>
   
   <p>
   Typical operation is something along these lines for OMAP/beagle:
   
   <blockquote><pre>
   # <b>mkuboot -a arm -o linux -e 0x80300000 -l 0x80300000 <i>bsd</i> bsd.umg</b>
   </pre></blockquote>
   
   for i.MX6:
   
   <blockquote><pre>
   # <b>mkuboot -a arm -o linux -e 0x10300000 -l 0x10300000 <i>bsd</i> bsd.umg</b>
   </pre></blockquote>
   
   where <i>bsd</i> is the name of the kernel you are converting.
   
   <p>
   <b>U-Boot tricks:</b>
   <ul>
   <li>Booting single user (OMAP/beagle):
   
   <blockquote><pre>
   U-Boot# mmc rescan
   U-Boot# setenv bootargs sd0 -s
   U-Boot# fatload mmc 0 0x82800000 bsd.umg
   U-Boot# bootm 0x82800000
   </pre></blockquote>
   
   <li>Booting single user (i.MX6, mmc storage):
   
   <blockquote><pre>
   U-Boot# mmc rescan
   U-Boot# setenv bootargs sd0 -s
   U-Boot# fatload mmc 0 0x12000000 bsd.umg
   U-Boot# bootm 0x12000000
   </pre></blockquote>
   
   <li>Booting single user (i.MX6, SATA storage):
   
   <blockquote><pre>
   U-Boot# sata init
   U-Boot# setenv bootargs sd0 -s
   U-Boot# fatload sata 0 0x12000000 bsd.umg
   U-Boot# bootm 0x12000000
   </pre></blockquote>
