Hi,
I have with me a bunch of "raw" Micro SD Cards (which I got
from a friend of my friend). Their capacity as reported by
Linux/Windows is around 30 MB. Further, most of the fields in
their CID and CSD register are empty. For example, the
following values are set, Manufacturer ID: 0x00 ;

Hi Jaehoon,

The Versatile Express IOFPGA as shipped on VECD 5.0 (bitfiles v108/208
and v116/216) contains a modified version of the PL180 MMCI, with
PeriphID Configuration value changed to 0x2.
This version adds an optional "hardware flow control" feature. When
enabled MMC card clock will be automatically dis

There are currently two instances of the ios_handler being used.
Both of which mearly toy with some regulator settings. Now there
is a GPIO regulator API, we can use that instead, and lessen the
per platform burden. By doing this, we also become more Device
Tree compatible.

From: Ulf Hansson
By using the mmc_regulator_get_supply API we are able to do some
cleanups of the regulator code. Additionally let the regulator
API handle the error printing.

From: Ulf Hansson
In this patchset the mmci driver is converted to use the new
mmc_regulator_get_supply API for handling regulators and OCR
mask.
On top of that we are taking the first step of moving away
from using the platform callback, ios_handler, to be more
DT compliant.

Hi Kevin,

The protocal related code is moved to core stack. So update the host

Cycle power the card is a MUST step when voltage switch sequence failed.
So move this operation to function mmc_set_signal_voltage.
