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

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.

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.

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).

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).

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.

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

Import old unfinished FT232R bit-banging code for sim sniffing

This code never really worked due to large sample clock jitter, lost
USB messages and the lack of CLK sniffing ability
