[Ovmsdev] External Wifi antenna

[Michael Balzer]

Craig,

congratulations to a successful heart transplantation :-)

Regarding RAM, I think you need to enable bank switching 
(CONFIG_SPIRAM_BANKSWITCH_ENABLE).

Please also disable the PSRAM bug workaround and maybe do some 
performance comparison. SPIRAM operations should run much faster without 
the workaround.

Regards,
Michael
