Basic support for Hawkboard OMAPL138 just UART cominication is included
Signed-off-by: Victor Rodriguez <[email protected]>
Notes: This patch deletes empty lines and typo mistakes from previous version
This patch is checked with 0a50e05b20f3c6af67656303bdb3661a2541ce03 from
Kernel development tree for TI DaVinci family of processors
This patch works with basic da8xx_omapl_defconfig, it just have basic
support
for UART console
This patch just works with UART 2 for argo file system
