SceSdif is a kernel module that is primary responsible for communicating with SD devices. This includes onboard eMMC, game card MMC, wi-fi/bluetooth SDIO devices.
To communicate with particular device SceSdif module uses device index (sd_ctx_index)

this function can execute all initialization commands just as initialize_sd_context_part (22c82e79) function.
these commands include: cmd0, cmd2, cmd3, cmd5_sdio, cmd6, cmd55, acmd41, cmd9, cmd7, cmd16, cmd8
there are couple of differences however:
- it can execute cmd42 lock/unlock command.
- it does not check sd_ctx_index argument.
- it uses array of 3 custom contexts instead of sd_context_part structures.
- it checks device type index after preinitialization (cmd0, cmd8, cmd5_sdio, cmd55, acmd41)
- it only initializes device with device type index 2.
