SDIO stack in RTEM

[faizan khan]

I dont get it, RTEMs has a port of sdmmc stack https://git.rtems.org/rtems-l
ibbsd but not all the drivers are using it. For example I saw, stmf32
implement its own command sending mechanism. Shouldnt that be generic, the
sending of commands. Only the lower controller level detail should change.

Also I don't get the connection with freebsd code, do we use that code
directly in RTEMs, is all of that ported???

Just want to understand the structure of RTEMs...

cheers,
Faizan
