Trying to get the schematics released, and been stuck on USB all day.

There are so many app notes, hints, errata that it's been hard going.
I think I'm about to kill off HSUSB2, since it's useless without a hub.
This would leave us with USB0 (HS, OTG) and USB1 (HS, Host only, routed
into a 4-port hub chip with a 10/100 ethernet port on the side.)

Did anyone have ambitions for a second HS-only USB port?
(Killing it will give us

mcspi3_simo
mcspi3_somi
mcspi3_cs0
mcspi3_clk
mcspi3_cs1

mcbsp5_dr
mcbsp5_fsx
mcbsp5_dx
mcbsp5_clkx

- so that's a very handy extra SPI port and another MCBSP
and also some DRM stuff

sys_drm_msecure
sys_secure_indicator

that looks more appealing re-tasked as
gpio_22
gpio_23

)

Comments?
