If zynqmp_qspi_set_speed() is called multiple times with the same speed,
then on the second call it will skip recalculating the baud_rate_val as
it assumes the speed is already configured correctly. But it will still
write the baud_rate_val to the configuration register and call
zynqmp_gqspi_set_tapdelay(). Because it skipped recalculating the
baud_rate_val, it will use the initial value of 0 . This causes the
driver to run at maximum speed which for many spi flashes is too fast and
causes data corruption.
Instead only write out a new baud_rate_val if we have calculated the
correct baud_rate_val.
This opens up another issue with the "if (speed == 0)", we don't save
off the new plat->speed_hz value when setting the baud rate on the
speed=0 path. Instead mimic what the Linux zynqmp gqspi driver does, and
have speed==0 just use the same calculation as a normal speed. That will
cause the baud_rate_val to use the slowest speed possible, which is the
safest option.

i2c changes for v2021.04
new feature:
- Allow disabling driver model for I2C in SPL
fixes:
- i2c-gpio: Fix GPIO output
- at91: fix crash when using 'i2c probe'
Use CONFIG_IS_ENABLED() macro, which provides more convenient
way to check $(SPL)DM_I2C/$(SPL)DM_I2C_GPIO configs
for both SPL and U-Boot proper.
CONFIG_IS_ENABLED(DM_I2C) expands to:
- 1 if CONFIG_SPL_BUILD is undefined and CONFIG_DM_I2C is set to 'y',
- 1 if CONFIG_SPL_BUILD is defined and CONFIG_SPL_DM_I2C is set to 'y',
- 0 otherwise.
All occurences were replaced automatically using these bash cmds:
$ find . -type f -exec sed -i
's/ifndef CONFIG_DM_I2C/if !CONFIG_IS_ENABLED(DM_I2C)/g' {} +
$ find . -type f -exec sed -i

At present if U-Boot proper uses driver model for I2C, then SPL has to
also. While this is desirable, it places a significant barrier to moving
to driver model in some cases. For example, with a space-constrained SPL
it may be necessary to enable CONFIG_SPL_OF_PLATDATA which involves
adjusting some drivers.
This patch introduces a separate Kconfig symbols for enabling DM_I2C and
DM_I2C_GPIO support in SPL.
This will also help to get away from dirty workarounds to
achieve non-DM I2C support for SPL, which is currently used in some
board header files like:
ifdef CONFIG_SPL_BUILD
undef CONFIG_DM_I2C
endif

After command is sent and before card response shows up on the line,
there is a variable number of clock cycles in between called Ncr.
The spec [1] says the minimum is 1 byte and the maximum is 8 bytes.
Current logic in mmc_spi_sendcmd() has a flaw that it could only work
with certain SD cards with their Ncr being just 1 byte.
When resp_match is false, the codes try to receive only 1 byte from
the SD card. On the other hand when resp_match is true, the logic
happens to be no problem as it loops until timeout to receive as many
bytes as possible to see a match of the expected resp_match_value.
However not every call to mmc_spi_sendcmd() is made with resp_match
being true hence this exposes a potential issue with SD cards that
have a larger Ncr value.
Given no issue was reported as of today, we can reasonably conclude
that all cards being used on the supported boards happen to have a 1
byte Ncr timing requirement. But a broken case can be triggered by
utilizing QEMU to emulate a larger value of Ncr (by default 1 byte
Ncr is used on QEMU). This commit fixes such potential spec violation
to improve the card compatibility.
