Hi, guys,
I need to support multiple systems with and without eMMC flash, using single
software.
I used to check /sys/block/mmcblk0/device/cid file to decide whether eMMC
flash exists or not on the system.
But it seems that the sysfs file might be brought up slowly (though it's very
unusual,

According to the eMMC/SD/SDIO specs the VDD voltage level must not be changed
during the initialization, without a complete power cycle of the card.
Before this patchset, some host drivers were trying to change voltage level
at MMC_POWER_ON state, which is also what the protocol layer advised

This is yet another step of restructure code to be able to fixup the
setup of the negotiated ocr mask.

As a step to fixup the setup of the negotiated ocr mask, we need the
mmc_power_up|cycle functions to take the ocr as a parameter.

At several places in mmc_sdio_init_card function the cached mask in
host-ocr were being updated. To simplify code, we make use of an
local ocr parameter instead.

The negotiated ocr mask is directly related to the card. Once a card
gets removed, the mask shall be dropped. By moving the cache of the ocr
mask from the host struct to the card struct we have accomplished this.

The retry and fallback mechanism when failing to switch to 1.8V
signaling voltage is handled by the SDIO card init function. Thus we
can remove the duplicated old code from the attach function.

Since mmc_select_voltage now only gets called from the attach sequence,
it makes sense to move the out of spec validations of the card ocr into
this function.

According to eMMC/SD/SDIO specs, the VDD (VCC) voltage level must be
maintained during the initialization sequence. If we want/need to tune
the voltage level, a complete power cycle of the card must be executed.
Most host drivers conforms to the specifications by only allowing to
change VDD
