SD host driver documentation?

I would like to know if there is some documentation about the
development of a SD host driver.
I found the code of the PXA driver and the comments inside sdhcd.h but
no documentation of SD host to SDBUS driver APIs.
I did my first googlewacking* searching for SDHCDRegisterHostController
and this is not a good thing...
I know I can implement the driver using the existing one as sample
etc., but having some docs detailing the expected behaviour of the
functions that I'm going to implement would be better.

* getting one and only one result from a google search

Ths source code of SDBUS could be found at
$(_WINCEROOT)\PUBLIC\COMMON\OAK\DRIVERS\SDCARD\SDBUSDRIVER\ folder, you may
want to take a look at it.

I foud this one also, but I hoped that there was something more than
code...
I'm not saying that code is not useful, the availability of a lot of
source code is one of the best features of CE, IMHO, but I hoped to
find some description of the interface between the hardware-specific
host controller driver and the SDBUS layer, like there is for many
other driver architectures in CE...
I found some BSQUARE copyright references in the includes and I suppose
that the SD drivers part was not developed directly by microsoft, and
this could explain the lack of resources in PB documentation.

Valter,
could you please contact me? (I don't want to be off topic here)
Delete the underscores in my email address...
Or at least can you provide a valid email address?
I have some questions about your training courses.
Ciao,
UF

There is some generic info on the MSDN, but it's not specific to CE:
- SD Bus Design Guide:
http://msdn2.microsoft.com/en-us/library/ms789949.aspx
- SD Bus Reference:
http://msdn2.microsoft.com/en-us/library/ms789954.aspx

Not sure if that helps or not, but it helped me get a better
understanding of SD under Win32 in general. The CE5 and CE6beta docs
that I have are really sparse, more like nicely formatted headers.
