Do not over-expose the private dw_mmc API. The glue layer drivers at
this point shouldn't be aware and shouldn't use the generic
dwmci_send_cmd() and dwmci_set_ios() functions. Making those functions
public causes a "leaky abstraction" issue. It clutters the public
interface of generic dw_mmc driver and possibly leads to improper usage
of those functions, so it's a bad design.
If struct dm_dwmci_ops has to be extended, do so by copying it first
(like it's done for example in snps_dw_mmc driver). That also makes sure
the future changes to struct dm_dwmci_ops in dw_mmc driver will be
automatically reflected in all extended copies, and avoid code
duplication.
This effectively reverts commit ef3b16bb8e73 ("mmc: dw_mmc: export
dwmci_send_cmd() and dwmci_set_ios()").
No functional change.

OPTEE-OS on ARMv7a"
This series from Marek Vasut <[email protected]> brings some
enhancements to use cases using OPTEE-OS on ARMv7a platforms, some of
which already existed on ARMv8.

Add support for jumping to Linux kernel through OPTEE-OS on ARMv7a to SPL.
This is already supported on ARMv8a, this patch adds the ARMv7a support.
Extend the SPL fitImage loader to record OPTEE-OS load address and in case
the load address is non-zero, use the same bootm-optee.S code used by the
U-Boot fitImage jump code to start OPTEE-OS first and jump to Linux next.

Enable DFU SF on all i.MX6 DHSOM so the SPI NOR can be exposed via
DFU, and include dfu_alt_info which exposes the full SPI NOR via DFU.
To install new bootloader into the SPI NOR using DFU, it is necessary
to pad the u-boot-with-spl.imx to 0x400 Bytes offset first and then
send it to the board as follows:
"

The extension_overlay_cmd environment variable approach is specific to

bootstd) handle overlay loading differently.
Move the extension_overlay_cmd execution out of the core extension

A variety of Qualcomm features/fixes for this cycle, notably with a few
new platforms gaining support:
* Initial support for SDM670 (similar to SDM845), SM6350, and SM7150
platforms is added
* USB and UART issues on MSM8916 are addressed (improving stability/
reliability)
* Firmware loading is implemented for the GENI serial engine, this is
used on some platforms to load firmware for i2c/spi/uart to work
Some additional patches like binman support for building MBN files still
need some additional work.

Qualcomm peripherals like UART, SPI, I2C, etc are all exposed under a
common GENI Serial Engine wrapper device. Replace the stub driver we use
for this currently with a full-on misc device and implement support for
loading peripheral firmware.
Each of the peripherals has it's own protocol-specific firmware, this is
stored on the internal storage of the device with a well-known partition
type GUID.
To support this, GENI will bind peripherals in two stages. First the
ones that already have firmware loaded (such as the serial port) are
bound in the typical way. But devices that require firmware loading are
deferred until EVT_LAST_STAGE_INIT. At this point we can be sure that
the storage device is available, so we load the firmware and then bind
and probe the remaining children.
Child devices are expected to determine if firmware loading is necessary
and call qcom_geni_load_firmware().
Since Linux currently doesn't support loading firmware (and firmware may
not be available), we probe all GENI peripherals to ensure that they
always load firmware if necessary.

Some boards have SD card connectors where the power rail cannot be switched
off by the driver. However there are various circumstances when a card
might be re-initialized, such as after system resume, warm re-boot, or
error handling. However, a UHS card will continue to use 1.8V signaling
unless it is power cycled.
If the card has not been power cycled, it may still be using 1.8V
signaling. According to the SD spec., the Bus Speed Mode (function group 1)
bits 2 to 4 are zero if the card is initialized at 3.3V signal level. Thus
they can be used to determine if the card has already switched to 1.8V
signaling. Detect that situation and try to initialize a UHS-I (1.8V)
transfer mode.

In the Linux kernel driver, all information related to LDO and BUCK
regulators are stored in descriptive arrays. This also allows multiple
variants to be supported by the same driver.
Define a struct sec_regulator_desc which holds all values required by a
regulator. Create an array of said struct containing all regulators. The
descriptors are designed to follow a style similar to what's seen in the
Linux driver, so comparing one with the other is simple.
In functions such as s2mps11_{buck,ldo}_{val,mode} these values are to
be used, make necessary modifications to pull them from the descriptors.
Since multiple variants have varying descriptors, select them from
within a switch-case block.
Functions s2mps11_{buck,ldo}_{volt2hex,hex2volt} and arrays
s2mps11_buck_{ctrl,out} are phased out as the calculations are now
hardcoded in descriptors, thusly, it reduces clutter and enhances
readability.
Two macros in s2mps11.h, S2MPS11_LDO_NUM and S2MPS11_BUCK_NUM are
removed as they are no longer being used.

During a voltage switch command (CMD11, opcode: SD_CMD_SWITCH_UHS18V),
certain hosts tend to stop responding to subsequent commands. This is
addressed by introducing an additional command flag,
DWMCI_CMD_VOLT_SWITCH.
The associated interrupt bit is defined as DWMCI_INTMSK_VOLTSW. This is
set high when a voltage switch is issued, this needs to be waited for
and set to low. Implement the same in the timeout loop. Do note that
since DWMCI_INTMSK_VOLTSW shares the same bit as DWMCI_INTMSK_HTO (bit
10), the interrupt bit needs to be polled for only if the volt switch
command is issued.
DWMCI_CMD_VOLT_SWITCH also needs to be set for subsequent clken commands
after the volt switch. To ensure this, add a boolean member in the host
private struct (herein named volt_switching), which informs if the last
command issued was for volt switching or not.

The current 'doing_global' refers to being in the state of processing

bootstd interation, add a new 'have_global' flag which tracks whether
there are any global bootmeths in the method_order[] list. It is set up
when iteration starts. Unlike doing_global which resets back to false
after the global bootmeths have been handled, once have_global is set to
true, it remains true for the entire iteration process. This provides a
quick check as to whether global-bootmeth processing is needed.

The current spl_board_fixups API allows for modification of spl_image
before the SPL jumps to it. This can be used to modify the DT for the
next boot stage, however the current API only allows either the machine
arch or the board to use it.
This limits the utility of the API as there might be certain fixups that
should be applied to all boards sharing the same machine architecture
with others being board specific.
For TI's K3 specifically, this prevents us from performing architecture
level fixups since a lot of TI boards are already making use of the
spl_board_fixups API.
Therefore this patch splits the API into two to allow both board and the
architecture specific fixups. The order is kept as arch then board to
give board specific fixups the precedence.
