| 1 # This feature is specific to Compal and Pirelli targets. When we put our own | |
| 2 # FreeCalypso firmware on these phones, we are using them in a way that is very | |
| 3 # different from how they were intended to be used by their respective | |
| 4 # manufacturers. Hence the term "aftermarket". Although the original firmwares | |
| 5 # of these phones are TI-based and feature TI-based flash file systems, neither | |
| 6 # Pirelli's FFS nor that of any Compal variant is suitable for direct reuse by | |
| 7 # FreeCalypso GSM fw. | |
| 8 # | |
| 9 # Therefore, if we are putting our own fw on one of these aftermarket devices | |
| 10 # and we need to use a real non-volatile FFS in flash, rather than fake FFS | |
| 11 # in RAM, we need to define our own aftermarket FFS, and we can put it in any | |
| 12 # part of the flash that suits our needs, without much regard for Compal's or | |
| 13 # Foxconn's originally intended flash layout - what we are doing with their | |
| 14 # hardware goes totally against their intentions anyway. | |
| 15 # | |
| 16 # Because our aftermarket FFS configuration inherently involves our own choice | |
| 17 # of flash location for this FFS, the present feature aftermarket-ffs takes two | |
| 18 # required arguments: the starting flash sector number and the total number of | |
| 19 # flash sectors to be used for the aftermarket FFS. It is the user's | |
| 20 # responsibility to ensure that these numbers are sensible. | |
