Need more IO #32

Would be nice to have UART2 RX/TX pined out on new C Rev.

More I/O expansion is needed. How about the keypad and extra GPIO on 4030.

If there is no room for actual connector how about just some feedthrough 
vias to solder to.

UART2TX/RX are on the BeagleBoard already and are available on the expansion 
connector.

The expansion connector is full so there is no room for adding TWL4030 I/O to 
the 
board. In addition, adding any additional I/O will result in more layers being 
added 
to the board and the cost of the board will increase siginificantly. As adding 
feedthrus would result in the layers being added, that is not a viable soultion 
for 
us at this time. We spent a lot of time in the begining taking things off to 
get the 
cost down. While I understand that these changes may seem simple, where does it 
take 
us? 25 simple changes ends up to one BIG change. This is not a ptah we can 
afford to 
go down on Beagle.

I have no plans to make these changes.
