 /*
  * The const T_RF_BAND rf_{900,1800,850,1900} structures that follow
- * are the versions that appear in the .const section of l1_cust.obj
- * in the l1_custom_int.lib Leonardo blob, used successfully in leo2moko.
- * As revealed with objgrep, this .const section with these uncalibrated
- * defaults in it also appears in the moko11 binary - I'm guessing that
- * Openmoko probably had no source for this part either, and used TI's
- * standard Leonardo binary lib.  The pretty C formatting presented here
- * is courtesy of the calextract utility.
+ * provide compiled-in defaults for each frequency band.  The present
+ * FreeCalypso versions of these structs began life as verbatim extracts
+ * from Openmoko's l1_cust.obj blob made with our calextract utility,
+ * providing undisrupted continuity from previous built-from-blobs
+ * firmwares, but have since been modified as follows:
+ *
+ * - The uncalibrated default g_magic values for all bands have been
+ * set to 200, which is the approximately correct number on FC/OM hw.
+ * The numbers in TI's l1_cust.obj blob delivery were quite obviously
+ * unchanged from Clara RF, and probably weren't even correct for the
+ * original Leonardo, let alone OM.
  *
- * Late 2017 addition: when building the fw for Compal targets, we use the
- * ramps tables extracted from C139 firmware, so we run with Tx ramp
- * templates that are supposed to be correct for the hw we are running on.
+ * - The uncalibrated default Rx and Tx channel calibration tables
+ * have been cleaned up.  The only sensible default is to set all
+ * channel corrections to neutral (0 for Rx and 128 for Tx), which the
+ * original blob versions already did, but many of those copy-n-pasted
+ * tables had ARFCNs that are invalid for the band they are supposed
+ * to apply to.  The latter bug has been fixed.
+ *
+ * - For the Tx ramps tables we now select between two different versions
+ * at compile time: for Mot C1xx targets (CONFIG_TARGET_COMPAL) we use
+ * the version extracted from Mot's official C139 fw, whereas for all
+ * other targets (principally FreeCalypso hw) we continue to use the
+ * version extracted from OM's l1_cust.obj blob.
+ *
+ * NONE of these compiled-in tables matter if you are running the fw
+ * on an Openmoko, Pirelli or FreeCalypso device that has already been
+ * fully calibrated at the respective factory: in all of these cases
+ * all of these compiled-in tables are fully overridden by the factory-
+ * calibrated ones read from FFS, or in the Pirelli DP-L10 case,
+ * read from Pirelli's factory data block and written into FreeCalypso FFS
+ * by the pirelli-magnetite-init command you are supposed to issue
+ * in fc-fsio when you set up FC on this target.  Instead these
+ * compiled-in tables matter in the following use cases:
  *
- * When we build the fw for FreeCalypso targets (not Compal), we use the
- * original ramps tables from TI which are presumed to be correct for
- * Openmoko's RF3166 PA: these compiled-in ramps tables end up
- * in the FFS of our shipping products when our production calibration
- * station (or more precisely, fc-rfcal-txband) issues the me 104 command.
+ * - When FC fw is run on a Mot C1xx phone, our c1xx-calextr tool
+ * generates Rx agcparams, Rx channel calibration and Tx levels tables
+ * from Motorola's factory bits, but for the Tx ramp templates the tables
+ * compiled into our fw are used - hence these tables need to be correct
+ * for the target in question, which is why we have extracted and included
+ * the tables from Mot C139 official fw.  We also weren't able to grok
+ * Mot's way of doing Tx channel corrections, hence we run without those
+ * - thus we rely on the compiled-in channel calibration tables providing
+ * a neutral set of correction values.
+ *
+ * - Firmware images that are programmed into newly made FreeCalypso hw
+ * devices in the factory production environment prior to RF calibration
+ * need to have correct Tx ramp template tables in them, as well as
+ * indices in the Tx levels tables pointing to these ramps, plus the
+ * other 3 values in the T_RX_CAL_PARAMS structure besides g_magic:
+ * while all other table bits are generated from scratch by our
+ * fc-rfcal-rxband and fc-rfcal-txband programs without regard to
+ * any previous compiled-in values, the just-listed tables and fields
+ * are unchanged by the calibration procedure and must already be
+ * correct prior to it.
  *
- * For the Pirelli target the compiled-in ramps tables do not matter
- * as we use the ramps tables from Pirelli's factory data block on this
- * target, courtesy of the fc-fsio pirelli-magnetite-init command.
+ * The compiled-in default Tx levels tables have been kept unchanged
+ * from the original extracts from OM's l1_cust.obj blob.  There is
+ * no point in changing these tables because they are nothing but dummy
+ * placeholders in reality: these tables absolutely MUST be calibrated
+ * for the individual device unit before that device can be used safely
+ * on public land mobile networks (if you are not doing your own RF
+ * calibration, you need to extract and apply the original manufacturer's
+ * calibration records, like our c1xx-calextr and pirelli-magnetite-init
+ * tools do), and if the compiled-in tables are nothing but placeholders,
+ * it would be rather moot to argue whether set of numbers A or set of
+ * numbers B would make a better placeholder.
+ *
+ * For the Tx ramp templates on our newly made FreeCalypso hw we currently
+ * use the ramps tables extracted from OM's l1_cust.obj blob: they were
+ * used by OM, and our current RF hw is unchanged from OM GTA02.  However,
+ * these Tx ramp templates are currently only *assumed* to be correct,
+ * and no actual testing has been done yet - these Tx power ramps will
+ * need to be revisited and tested empirically before we apply for type
+ * approval certification.
