When using CMD6 to switch eMMC card timing from HS200/HS400 to HS/legacy,
do not poll for the completion status using CMD13, but rather wait 50mS.
Once the card receives the CMD6 and starts executing it, the bus is in
undefined state until both the card finishes executing the command and
until the controller switches the bus to matching timing configuration.
During this time, it is not possible to transport any commands or data
across the bus, which includes the CMD13.

The mmc_select_mode_and_width() function can be called while the card
is in HS200/HS400 mode and can be used to downgrade the card to lower
mode, e.g. HS. This is used for example by mmc_boot_part_access_chk()
which cannot access the card in HS200/HS400 mode and which is in turn
called by saveenv if env is in the MMC.
In such case, forcing the card clock to legacy frequency cannot work.
Instead, the card must be switched to HS mode first, from which it can
then be reprogrammed as needed.
However, this procedure needs additional code changes, since the current
implementation checks whether the card correctly switched to HS mode in
mmc_set_card_speed(). The check only expects that the card will be going
to HS mode from lower modes, not from higher modes, hence add a parameter
which indicates that the HS200/HS400 to HS downgrade is happening. This
makes the code send the switch command first, reconfigure the controller
next and finally perform the EXT_CSD readback check. The last two steps
cannot be done in reverse order as the card is already in HS mode when
the clock are being switched on the controller side.

We are currently using SC_R_LAST as a marker for imx8 power domain tree
nodes without a resource attached. This value is compiled into dtb as
part of the linux build and used by uboot.
The SC_R_LAST constant changes frequently as SCFW resources are added
(by design) and every time we need to update linux and uboot headers
together or boot can fail.
Fix this by replacing SC_R_LAST usage with a new constant SC_R_NONE
defined to be 0xFFF0.

Currenlty U1 and U2 low power modes are allowed in device mode.
Allowing U1 and U2 low power modes during data transfers in
device mode is causing U1 exit failure on some USB3 host: which
will transite to SS.inactive instead of U0, then host will send
warm reset and ultimately result in reenumeration. This is observed
on UUU tool with some PC host. Hence disable U1 and U2 low power
modes for now.
USB3 spec 7.5.10.4.2 Exit from Recovery.Configuration
The port shall transition to eSS.Inactive when the following
conditions are met:
1. Either the Ux_EXIT_TIMER or the 6-ms timer
(tRecoveryConfigurationTimeout) times out.
2. For a downstream port, the transition to Recovery is not to
attempt a Hot Reset.

Add a new private flag I2C_M_SRTM_STOP(0x0200) to indicate if STOP
is needed for current message.
When reading/writing registers for slave devices, generally we have two messages,
the first message writes the register address, second message reads/writes the value.
Only the last message needs STOP. But previously M4 sends STOP for each message,
this causes some slave devices treat it as end of transfer. Then, second message won't
have any effect. To solve the problem, we introduce this private STOP flag, so M4 can
STOP according to the flag.

When using the SDPV, the uuu will continue to send out data after first
level boot loader used by ROM. This means uuu won't skip to the offset
of the second boot loader, and the padding data before second boot loader
will be sent out. So we have to search the FIT header or container header
