640abba507 dm: spi: Do not assume first SPI bus
When CONFIG_OF_PRIOR_STAGE is enabled, this workaround was needed
before device_bind_common assigned request numbers sequentially in the
absence of aliases.

b47f4891e5 spi: bcm63xx_hsspi: Continue init when using no reset and fixed-clock.
The Broadcom ARM implementations do not yet have a clock framework so
one can use a fixed clock as the root clock of the hsspi block. The
fixed clock does not have an "enable" routine, since it's always
enabled. So when we hit this issue, getting an ENOSYS return, do not
bail but continue initialization.

Similarly the block might already have been out of reset, say, when
we are booting from a SPI device. So if the reset signal is not configured
in the device tree, do not bail out and instead skip deasserting the reset.

7949576664 spi: fsl_qspi: Fix DDR mode setting for latest iMX platforms
On latest iMX platforms like iMX7D/iMX6UL/iMX8MQ, the QSPI controller
is updated to have TDH field in FLSHCR register. According to reference
manual, this TDH must be set to 1 when DDR_EN is set. Otherwise, the TX
DDR delay logic won't be enabled.

Another issue in DDR mode is the MCR register will be overwritten in
every read/write/erase operation. This causes DDR_EN been cleared while
TDH=1, then no clk2x output for TX data shift and all operations will
fail.

c2050e10e1 spi: fix: Call mxs_reset_block() during DM/DTS probe
Without this change the DM/DTS version of mxs_spi driver doesn't reset the
SPI IP block in probe.
As a result this driver (when used solely on U-Boot proper) relies on reset
performed by mxs spi driver in SPL.

In the use case where eMMC is used in SPL as a boot primary device, the
mxs_reset_block() is not called at all and DM/DTS aware SPI driver in
U-Boot proper is malfunctioning.

In general we should avoid calling malloc() and free() repeatedly in
U-Boot lest we turn it into tianocore. In SPL this can make SPI flash
unusable since free() is often a nop and allocation space is limited.

In any case, these seems no need for malloc() since the number of bytes

67adbaef5a spi: mpc8xxx: Use get_timer
The comment before the transmission loop in conjunction with the
definition of SPI_TIMEOUT as 1000 implies that the loop is supposed to
have a timeout value of 1000 ms. But since there is no mdelay(1) or
similar in the loop body, the loop just runs 1000 times, without regard
for the time elapsed.

To correct this, use the standard get_timer functionality to properly
time out the loop after 1000 ms.

f6fcad5f2a spi: mpc8xxx: Fix if check
Decreasing the bit length and increasing the write data pointer should
be done when there are more than 32 bit of data, not 16 bit.

This did not produce incorrect behavior, because the only time where the
two checks produce different outcomes is the case of 16 < bitlen < 32,
and in this case the subsequent transmission is the last one regardless,
hence the additional bit length decrease and write data pointer increase
has no effect anyway.

Still, the correct check is the check for "bitlen > 32", so correct this
behavior.
