3fc0e7da79 Update BOM for v1.4
* AT91SAM128D, not C, as old is EOL
* New ferrite bead / filter, as old is EOL.
* Flash S25FL032P0XMFI011, was already populated in v1.3

21f7718e2f v1.4: Connect PA0 to 3V3; pull-up for PA1/PA2 (R25,R26)
PA0, PA1 and PA2 must be high during reset to enter SAM-BA mode.

e24db8d2b4 Schematic: Make sure PA0 to PA2 are high on power-up
any other level is interfering with SAM-BA operation.  This fixes
the PA0=GND bug in the previous v1.3 version.

bea975a05d add datasheet of SPI flash component mounted on recent boards
At some point during v1.2p production, we switched from the S25FL016
to the S25FL032P SPI flash model.  v1.3 all have that flash (so far).

4f0bebb1f9 Mark IC5 as "do not place" (VCC_Forward) as it doesn't work anyway
If the LDO is switched off, then even if we try to forward power from
the phone to the SIM, the current will sink inside the LDO (no reverse
current protection).

2590ed2f5b Add R23 (pull-up for !SIM_RST signal)
While the SAM7 has an internal pull-up, this is of no use if the bus
switch input is left open and collects noise resulting in bogus nRST
interrupts.

2ebce55aa4 SIMtrace: Improve PCB routing of GND, 3V3 and VCC traces
We have to make sure the impedance of the supply lanes is not too high.
Particularly bad was passing GND in 0.2mm under several resistors before
even reaching the LDO from the USB socket.

This attempts to address the major issues.  Also, the input capacitor is
moved closer to the LDO once again
