Whenever the SD Card would be removed and then re-inserted while in the
U-Boot command line, the `SDBPWR` bit of the `SDMMC_PCR` register would
remain unset afterwards. In order for the bit to be set again after
re-insertion, register an additional `deferred_probe` method that the
DM would then transparently call. This method will call the generic
`sdhci_probe` which will, during its execution flow, set this bit to 1.

When fixed offset via CONFIG_SYS_MMC_U_BOOT_OFFS is not specified then
expects that U-Boot proper is placed immediately after SPL without any
additional padding.
This allows to generate smaller SPL+U-Boot final binary as it is not
required to specify fixed offset to U-Boot proper at SPL compile time.
In this case offset to U-Boot proper is calculated at SPL compile time in

This option is fact really related to SPL. For U-Boot proper we always use
driver model for block devices, so CONFIG_BLK is enabled if block devices
are in use.
It is only for SPL that we have two cases:
- SPL_BLK is enabled, in which case we use driver model and blk-uclass.c
- SPL_BLK is not enabled, in which case (if we need block devices) we must
use blk_legacy.c
Rename the symbol to SPL_LEGACY_BLOCK to make this clear. This is
different enough from BLK and SPL_BLK that there should be no confusion.

Commit 44645f87de ("mmc: Fix mmc_switch excessive timeout") introduced
a side effect where CMD13 SEND_STATUS is issued in case mmc_wait_dat0()
does not return -ENOSYS and $send_status is not set. This happens on all
hardware which does implement .mmc_wait_dat0 callback, e.g. i.MX8M .
This leads to lengthy timeout before booting OS in case of eMMC in one
of the HS200/HS400 modes, since the card cannot respond to CMD13 while
downgrading from HS200/HS400 to regular HS mode.
Fix this by adding the missing conditional.

The Aspeed SDHCI controller is arranged with some shared control
registers, followed by one or two sets of actual SDHCI registers.
Adjust the driver to probe this controller device first. The driver then
wants to iterate over the child nodes to probe the SDHCI proper:
ofnode node;
dev_for_each_subnode(node, parent) {
struct udevice *dev;
int ret;
ret = device_bind_driver_to_node(parent, "aspeed_sdhci",
ofnode_get_name(node),
node, &dev);
if (ret)
return ret;
}
However if we did this the sdhci driver would probe twice; once
"naturally" from the device tree and a second time due to this code.
Instead of doing this we can rely on the probe order, where the
controller will be set up before the sdhci devices. A better solution is
preferred.
Select MISC as the controller driver is implemented as a misc device.

The bulk of it is (finally!) some DT sync from the kernel. We refrained
from syncing one incompatible change, as this would spoil booting Linux
kernels before v5.13 with U-Boot's DT (via UEFI, for instance).
I test booted Linux v5.18 and v5.4 with that new DT on some boards, and
the headless peripherals (MMC, USB, Ethernet) seemed to work.
The rest are fixes:
- silencing missing clock warnings due to the new pinctrl driver
- fixing "UART0 on PortF", allowing UART access through the SD card pins
- add an F1C100s clock driver, to enable MMC support (SPI comes later)
- some cleanups for CONS_INDEX_n in Kconfig
Tested on BananaPi-M1, Pine64-LTS, Pine-H64, X96-Mate (H616) and
OrangePi-Zero.
Now that the pinmux conflict is handled in the board code (by skipping
setup for the one conflicting MMC controller), the driver does not need
to be entirely disabled based on the UART pinmux.

On RK3568, a register bit must be set to enable Enhanced Strobe.
However, it appears that the address of this register may differ from
vendor to vendor and should be read from the underlying MMC IP. Let the
Rockchip SDHCI driver read this address and set the relevant bit when
Enhanced Strobe configuration is requested.
The IP uses a custom mode select value (0x7) for HS400, use that instead
of the common but non-standard SDHCI_CTRL_HS400 value (0x5). Also add
some necessary DLL_STRBIN and DLL_TXCLK configuration for HS400.
Additionally, a bit signifying that the connected hardware is an eMMC
chip must be set to enable Data Strobe for HS400 and HS400ES modes. Also
make the driver set this bit as appropriate.
This is partly ported from Linux's Synopsys DWC MSHC driver which
happens to be the underlying IP. (drivers/mmc/host/sdhci-of-dwcmshc.c in
Linux tree).

On RK3399, a register bit must be set to enable Enhanced Strobe.
Let the Rockchip SDHCI driver set it when Enhanced Strobe configuration
is requested. However, having it set makes the lower-speed modes stop
working and makes reinitialization fail, so let it be unset as needed in
set_control_reg().
This is mostly ported from Linux's Arasan SDHCI driver which happens

Generic SDHCI driver received support for checking the busy status by
polling the DAT[0] level instead of waiting for the worst MMC switch time.
Unfortunately, it appears that this does not work for Xenon controllers
despite being a part of the standard SDHCI registers and the Armada 3720
datasheet itself telling that BIT(20) is useful for detecting the DAT[0]
busy signal.
I have tried increasing the timeout value, but I have newer managed to
catch DAT_LEVEL bits change from 0 at all.
This issue appears to hit most if not all SoC-s supported by Xenon driver,
at least A3720, A8040 and CN9130 have non working eMMC currently.
So, until a better solution is found drop the wait_dat0 OP for Xenon.
I was able to only test it on A3720, but it should work for others as well.

After commit f132aab403 ("Revert "mmc: fsl_esdhc_imx: use
VENDORSPEC_FRC_SDCLK_ON to control card clock output""), it
involve issue in mmc_switch_voltage(), because of the special
design of usdhc.
For FSL_USDHC, it do not implement VENDORSPEC_CKEN/PEREN/HCKEN/IPGEN,
these are reserved bits(Though RM contain the definition of these bits,
but actually internal IC logic do not implement, already confirm with
IC team). Instead, use VENDORSPEC_FRC_SDCLK_ON to gate on/off the card
clock output. Here is the definition of this bit in RM:
[8] FRC_SDCLK_ON
Force CLK output active
Do not set this bit to 1 unless it is necessary. Also, make sure that
this bit is cleared when uSDHC’s clock is about to be changed (frequency
change, clock source change, or delay chain tuning).
0b - CLK active or inactive is fully controlled by the hardware.
1b - Force CLK active
In default, the FRC_SDCLK_ON is 0. This means, when there is no command
or data transfer on bus, hardware will gate off the card clock. But in
some case, we need the card clock keep on. Take IO voltage 1.8v switch
as example, after IO voltage change to 1.8v, spec require gate off the
card clock for 5ms, and gate on the clock back, once detect the card
clock on, then the card will draw the dat0 to high immediately. If there
is not clock gate off/on behavior, some card will keep the dat0 to low
level. This is the reason we fail in mmc_switch_voltage().
To fix this issue, and concern that this is only the fsl usdhc hardware
design limitation, set the bit FRC_SDCLK_ON in the beginning of the
wait_dat0() and clear it in the end. To make sure the 1.8v IO voltage
switch process align with SD specification.
For standard tuning process, usdhc specification also require the card
clock keep on, so also add these behavior in fsl_esdhc_execute_tuning().

The Rockchip RK3399 eMMC PHY has to be power-cycled while changing its
clock speed to some higher speeds. This is dependent on the desired
SDHCI clock speed, and it looks like the PHY should be powered off while
setting the SDHCI clock in these cases.
Commit ac804143cf ("mmc: rockchip_sdhci: add phy and clock config for
rk3399") attempts to do this in the set_ios_post() hook by setting the
SDHCI clock once more while the PHY is turned off/on as necessary, as
the SDHCI framework does not provide a way to override how it sets its
clock. However, the commit breaks reinitializing the eMMC on a few
boards including chromebook_kevin and reportedly ROCKPro64.
This patch reworks the power cycling to utilize the SDHCI framework
slightly better (using the set_control_reg() hook to power off the PHY
and set_ios_post() hook to power it back on) which happens to fix the
issue, at least on a chromebook_kevin.

Add support for dynamic configuration which will takes care of

- Put the SD Controller in reset.
- Configure SD Fixed configurations.
- Configure the SD Slot Type.
- Configure the BASE_CLOCK.

translator is optional, as the translator can be auto-detected by the

The translator test sets CMD high to avoid interfering with a card, and
then verifies whether signal set on CK is detected on CKIN. If the signal
