[flashrom] ft2232_spi JTAGkey OE disabled for CS high

[Ulrich Holeschak]

Hello,

when de-asserting CS:
    msg_pspew("De-assert CS#\n");
    buf[i++] = SET_BITS_LOW;
    buf[i++] = cs_bits;
    buf[i++] = pindir;



Filtering the OE bit fixes this issue:
    msg_pspew("De-assert CS#\n");
    buf[i++] = SET_BITS_LOW;
    buf[i++] = cs_bits & 0x0F;    // keep OE active
    buf[i++] = pindir;

Regards,
Ulrich

when using the ft2232_spi driver with Amontec JTAGkey, the OE signal (bit 4) is disabled This means that the CS high signal is floating and the voltage level is unstable.
