spl: nand: sunxi: use PIO instead of DMA
SPL support was first written to support only the earlier generations of
Allwinner SoCs, and was only really enabled on the A13 / GR8. However,
those old SoCs had a DMA engine that has been replaced since the A31 by
another DMA controller that is no longer compatible.
Since the code directly uses that DMA controller, it cannot operate
properly on the later SoCs, while the NAND controller has not changed.
There's two paths forward, the first one would have been to add support
for that DMA controller too, the second to just remove the DMA usage
entirely and rely on PIO.
The later has been chosen because CPU overload at this stage is not an
issue and it makes the driver more generic, and easier to understand.

spl: fix binman_sym output check
A previous commit introduced the use of binman in the SPL.
After the binman_sym call over the 'pos' symbol, the output value is
checked against BINMAN_SYM_MISSING (-1UL). According to the
documentation (tools/binman/README), when it comes to the 'pos'
attribute:
pos:
This sets the position of an entry within the image. The first
byte of the image is normally at position 0. If 'pos' is not
provided, binman sets it to the end of the previous region, or
the start of the image's entry area (normally 0) if there is no
previous region.
So instead of checking if the return value is BINMAN_SYM_MISSING, we
should also check if the value is not null.
The failure happens when using both the SPL file and the U-Boot file
independently instead of the concatenated file (SPL + padding + U-Boot).
This is because the U-Boot binary file alone does not have the U-Boot
header while it is present in the concatenation file. Not having the
header forces the SPL to discover where it should load U-Boot. The
binman_sym call is supposed to do that but fails. Because of the wrong
check, the destination address was set to 0 while it should have been
somewhere in RAM. This, obviously, stalls the board.

sunxi: move CONFIG_SYS_TEXT_BASE out of defconfigs
Commit
278b90ce786f ("configs: Migrate CONFIG_SYS_TEXT_BASE") made
CONFIG_SYS_TEXT_BASE a proper Kconfig variable, with the consequence
of moving the common definition shared by almost every sunxi board
into 123 individual defconfig files. But the U-Boot start address
for Allwinner boards is a platform decision which has been around for
ages, so defining it in each *board* config file seems a bit over the

Define the standard values (160MB into DRAM for most SoCs, with two

mmc: stm32: sdmmc2: add support for st, pin-ckinsdmmc_ckin
This patch adds "st,pin-ckin" support to activate sdmmc_ckin feature.
When using an external driver (a voltage switch transceiver),
it's advised to select SDMMC_CKIN feedback clock input to sample
the received data.

mmc: stm32: sdmmc2: add hardware flow control support
The hardware flow control functionality is used to avoid
FIFO underrun (TX mode) and overrun (RX mode) errors.
The behavior is to stop SDMMC_CK during data transfer and
freeze the SDMMC state machines.
