This file is a quick list of the things that are being considered
47+
for future development in CFE as it matures.
48+
49+
Customers: I welcome your comments (good and bad).
50+
51+
52+
------------------------------------------------------------------------------
53+
FEATURES YET TO BE IMPLEMENTED
54+
------------------------------------------------------------------------------
55+
56+
* No user interface
57+
58+
One way we envision CFE being used is with no user interface whatsoever;
59+
it will be used to initialize the BCM12500 and launch a program,
60+
and that's all. This configuration might be popular in systems
61+
with many BCM12500s, where the slave BCM12500s do not need
62+
console interfaces of their own.
63+
64+
* Simple scripts
65+
66+
CFE needs some simple script mechanism (it could be as simple as a set
67+
of commands stored in an environment variable), and a way to invoke
68+
the script on startup. For example, such a script could configure
69+
the network interface and start a netboot from that interface.
70+
71+
* Power-on Diagnostics
72+
73+
Once we have a reasonable set of power-on diagnostics, they
74+
will be incorporated into the firmware.
75+
76+
* Set/configure serial port baud rate, store rate in flash
77+
78+
* Better "test" commands for tinkering with SOC peripherals
79+
80+
81+
------------------------------------------------------------------------------
82+
FEATURES IN PROGRESS, NOT COMPLETED
83+
------------------------------------------------------------------------------
84+
85+
* User's Manual improvements
86+
87+
The user's manual needs to be improved to fill in the missing
88+
sections, add additional sections, and convert the style to
89+
Broadcom's documentation standards. You'll be able to get
90+
the latest manuals from DocSafe when this happens.
91+
92+
* Some API functions not implemented
93+
94+
Several of the API functions available via CFE's external API are not
95+
implemented, or are missing features.
96+
97+
98+
------------------------------------------------------------------------------
99+
IDEAS THAT WON'T NECESSARILY BE DONE
100+
------------------------------------------------------------------------------
101+
102+
* Write access to file systems
103+
104+
Write access to file systems is specifically *not* included in CFE for
105+
simplicity.
106+
107+
* Direct support for reading boot files via NFS
108+
109+
This is outside the design goals for CFE, but given enough requests
110+
it can be done easily.
111+
