+compal_e88
+==========
+
+This directory contains the board support for compal e88 phones.
+
+This port is based on patches contributed by Denis Carikli for both the
+compal e99 and e88. At the time of initial check-in, the following phones
+were tested:
+
+* motorolla c155 (compal e99) with the compalram and highram configuration
+* motorolla W220 (compal e88)
+* The openmoko freerunner baseband(compal e88)
+
+The patches were made by Alan Carvalho de Assis and Denis Carikli using
+the Stefan Richter's patches that can be found here:
+
+http://cgit.osmocom.org/cgit/nuttx-bb/log/?h=lputt%2Ftesting
+
+http://bb.osmocom.org/trac/wiki/nuttx-bb/run detail the usage of nuttx with
+sercomm(the transport used by osmocom-bb that runs on top of serial).
+
+The way of loading nuttx(which is also documented in osmocom-bb wiki) depend
+on the configuration(highram/compalram) and phone:
+
+compalram is for the ramloader(for phone having a bootloader on flash)
+highram is for phones having the romloader(if the phone has a bootrom) or for
+loading in the ram trough a special loader(loaded first on ram by talking to
+the ramloader) when having a ramloader(which can only load 64k).
