fc8048a88e mmc: fsl_esdhc: make GPIO support optional
There would be compiling error as below when enable driver model for esdhc.
undefined reference to `dm_gpio_get_value'
undefined reference to `gpio_request_by_name_nodev'
This patch is to make GPIO support optional with CONFIG_DM_GPIO. Because
all boards of QorIQ platform don't need it and they just check register for
CD/WP status, only some boards of i.MX platform require this.

There are more than five kinds of Layerscape SoCs. unfortunately,

According to Section 11.15.4.9.1 Indirect Read Controller of K2G SoC
TRM SPRUHY8D[1], the external master is only permitted to issue 32-bit
data interface reads until the last word of an indirect transfer
So, make sure that QSPI indirect reads are 32 bit sized except for the
final read. If the rxbuf is unaligned then use bounce buffer, so that
readsl() can be used instead of readsb() to avoid non 32-bit accesses.

45a68fe267 mmc: move some SDHCI related options to Kconfig

[2] create the Kconfig entries in drivers/mmc/Kconfig

[3] Move the options by the following command

e298c46ac3 mmc: make MMC driver entries dependent on MMC
Currently, CONFIG_MMC is not related to any other options by
"depends on" or "select".  One of big advantages of using Kconfig
is automatic dependency tracking, but the current state is lacking
it.  As the first step, make the existing MMC driver entries depend
on MMC.

This commit was created by the following steps:

[1] Run the following script:

c27269953b mmc: complete unfinished move of CONFIG_MMC
Commit 7a777f6d6f ("mmc: Add generic Kconfig option") created
a Kconfig entry for this option without any actual moves, then
commit 44c798799f ("sunxi: Use Kconfig CONFIG_MMC") moved
instances only for SUNXI.

We generally do not like such partial moves.  This kind of work
is automated by tools/moveconfig.py, so it is pretty easy to
complete this move.

I am adding "default ARM || PPC || SANDBOX" (suggested by Tom).
This shortens the configs and will ease new board porting.

This commit was created as follows:

[1] Edit Kconfig (remove the "depends on", add the "default",
    copy the prompt and help message from Linux)

[2] Run 'tools/moveconfig.py -y -s -r HEAD MMC'

e8a016b537 dm: Add support for scsi/sata based devices
All sata based drivers are bind and corresponding block
device is created. Based on this find_scsi_device() is able
to get back block device based on scsi_curr_dev pointer.

intr_scsi() is commented now but it can be replaced by calling
find_scsi_device() and scsi_scan().

scsi_dev_desc[] is commented out but common/scsi.c heavily depends on
it. That's why CONFIG_SYS_SCSI_MAX_DEVICE is hardcoded to 1 and symbol
is reassigned to a block description allocated by uclass.
There is only one block description by device now but it doesn't need to
be correct when more devices are present.

scsi_bind() ensures corresponding block device creation.
uclass post_probe (scsi_post_probe()) is doing low level init.

SCSI/SATA DM based drivers requires to have 64bit base address as
the first entry in platform data structure to setup mmio_base.

0b060eefd9 serial: 16550: Add Ingenic JZ4780 support
Add compatibility string for the Ingenic JZ4780 SoC, the necessary
UART enable bit into FCR and register shift. Neither are encoded
in the DTS coming from Linux, so we need to support it this way.

79fd928188 serial: 16550: Add port type as driver data
Add driver data to each compatible string to identify the type of
the port. Since all the ports in the driver are entirely compatible
with 16550 for now, all are marked with PORT_NS16550. But, there
are ports which have specific quirks, like the JZ4780 UART, which
do not have any DT property to denote the quirks. Instead, Linux
uses the compatible string to discern such ports and enable the
necessary quirks.

from platform data for DM , while retaining old behavior for non-DM
by returning UART_FCRVAL.
