+ CONFIG_PSC3_USB
+ for USB on PSC3
CONFIG_USB_CONFIG
for differential drivers: 0x00001000

CONFIG_SYS_USB_EVENT_POLL
May be defined to allow interrupt polling
instead of using asynchronous interrupts
Defines a default value for the IP address of a TFTP
server to contact when using the "tftboot" command.
+ CONFIG_KEEP_SERVERADDR
+
+ Keeps the server's MAC address, in the env 'serveraddr'
+ for passing to bootargs (like Linux's netconsole option)

- Multicast TFTP Mode:
CONFIG_MCAST_TFTP
therefore be cleared to 0 (See, eg, MPC823e User's Manual
p.16-473). So, set CONFIG_SYS_I2C_SLAVE to 0.
+ CONFIG_SYS_I2C_INIT_MPC5XXX
+
+ When a board is reset during an i2c bus transfer
+ chips might think that the current transfer is still
+ in progress. Reset the slave devices by sending start
+ commands until the slave device responds.

That's all that's required for CONFIG_HARD_I2C.
If you use the software i2c interface (CONFIG_SOFT_I2C)
average for all boards 752 bytes for the whole U-Boot image,
624 text + 127 data).
