Good catch, I wonder if I missed these in last year's board removal
or if they were already broken back then. Some of these

I don't know if Steve still cares, but the board is still there
in arch/arm/mach-pxa/{gumstix,am200epd.c,am300epd.c}

Same here, the code is still there and used by pxa3xx:

arch/arm/mach-ep93xx/ts72xx.c is about to be obsoleted by the ongoing
DT conversion.

drivers/mmc/host/pxamci.c and drivers/rtc/rtc-pxa.c
are still in use.

This is still supported and it's x86 rather than arm.

There is a good chance that we /should/ remove it for being obsolete,
but that has to be a separate series and remove the drivers and
architecture support if we decide to go that way.

I'm fairly sure this platform was originally added for use with
OpenWRT but not everything was merged and OpenWRT stopped
carrying the required patches in 2016:

https://git.openwrt.org/?p=openwrt/openwrt.git;a=commitdiff;h=fed29fa36bf9ff387ff6e96522b1b5423fed3581

Some of the drivers might still be in use on the related
vortex86 cores, so maybe we keep the support and add
