Reduce the PFC tables by ifdeffing out pinmux settings which are
unlikely to be used by U-Boot. This helps reduce the size of the
bootloader in the 10 kiB range. This includes conditional build
of these PFC additions:
- Audio
- CAN/CANFD
- INTC/INTC-EX
- MSIOF
- PWM
- SSI

By default the pin multiplexing tables used by U-Boot are reduced
to keep the size of the bootloader low. This option allows build of
full pin multiplexing tables the same way they are included in the
Linux kernel. This includes pin multiplexing options for Audio, CAN,
CANFD, DU, INTC, INTC-EX, MSIOF, PWM, SSI, for which there is no
U-Boot driver. This option is disabled by default.

When FEC network card works as the prime one in u-boot, and is in
active status, kernel might crash during booting up stage, especially
working with grub. Because the DMA of FEC is still in active status, and
copy data into memory if there is network data received. In this case, if
kernel allocated a part of memory that has overlay with the memory
used by DMA, kernel memory may be destroyed and cause kernel crashes.
Because before kernel boots up really, u-boot dm_remove_devices_flags()
can call the remove callback of FEC driver with DM_FLAG_ACTIVE_DMA
flag. In fecmxc_remove(), phy power is disabled, so there is no data
received. In this way, it makes sure that there is no DMA action, so
that avoid kernel crashing occurs.

The mxc_get_clock function is around for compatibility with older
drivers that are not clock aware. In this case asking for the clk for
MXC_CSPI_CLK does not take into account there are multiple SPI busses on
modern IMX SoC's and it will return the clock for the first bus which
may not be used or configured.
In the case you are not using the first bus you will not get the proper
clock. Fix this by obtaining the clock rate from the bus clock.
This resolves an invalid SPI clock frequency configuration for SPI2 on a
board where SPI1 is not used.

TFTP transfers of large files, for example 128 MiB, can sporadically
get stuck and the transfer slows down considerably.
This happens because the TX DMA descriptor in DRAM becomes out of sync
with the view of the TX DMA descriptor content from the CPU side, which
is viewed through the CPU caches. In order to guarantee these two views
are consistent, the cache over TX DMA descriptor that has possibly been
written by the rswitch hardware must first be invalidated, only then can
the descriptor be cleared and updated by the CPU, and finally the cache
over that area must be flushed back into DRAM to make sure the rswitch
hardware has consistent view of the updated descriptor content.
The very first invalidation operation was missing, which led to sporadic
corruption of the TX DMA descriptor. Fix it, add the missing invalidation
operation.

Early revisions of the R-Car V4M Series Hardware User’s Manual
contained an incorrect formula for the CPU core clocks:
ZCnφ = (PLL2VCO x 1/2) x mult/32
Dang-san fixed this by using CLK_PLL2_DIV2 instead of CLK_PLL2 as the
parent clock.
In Rev.0.70 of the documentation, the formula was corrected to:
ZCnφ = (PLL2VCO x 1/4) x mult/32
As the CPG Block Diagram now shows a separate 1/4 post-divider for PLL2,
the use of CLK_PLL2_DIV2 is a recurring source of confusion. Hence get
rid of CLK_PLL2_DIV2, and include the proper 1/4 post-divider in the
invocation of the DEF_GEN4_Z() macro, like is done on other R-Car Gen4
(and Gen3) SoCs.
Ported from Linux commit

On 64bit systems the timer value might be truncated to a 32bit value
causing malfunctions. For example on ARM the timer might start from 0
again only after a cold reset. The 32bit overflow occurs after a bit
more than 49 days (1000 Hz counter) so booting after that time may lead
to a surprise because the board might become stuck requiring a cold
reset.

Currently if a gigabit-capable PHY is connected to FEC via RMII or MII, it
will advertise 1000FULL and 1000HALF to a link partner.
Different problems may arise here:
- usually with (R)MII between MAC and PHY the PHY's connection to magnetics
would have only 2 pairs routed as well, otherwise a PHY can negotiate 1000
speed and there will be no traffic possible;
- but even if there is no way to negotiate 1000 speed in HW (only 2 signal
pairs routed), it may take a lot of time for PHY to figure this out; in
case of AD1300 it takes 17-20 seconds, which is waay longer than default
4s PHY_ANEG_TIMEOUT.
Use phy_set_supported() in such cases to disable gigabit advertised
options.

Hi All,
In u-boot, hbmc is broken and has been removed from j7200
configs. This series re-enables the hbmc driver and introduces a series
of hyperflash boot fixes. At present, in u-boot, the parent device (fss)
gets registered as a syscon device. This is done because the MMIO
mux driver in u-boot did not support the mux functionality when the
parent device is not a syscon. In this series, we make relevant changes
in the hbmc driver as well as dts' so that we can use the reg-mux driver for
selecting the appropriate state of the mux.

Gokul Praveen <g-praveen@ti.com> says:
The OMAP specific UART driver is changed from a generic implementation of
certain ops functions to an OMAP specific implementation of it to add
support for higher baudrates for OMAP devices.
Hence to support the above change, static functionality of ops functions
in generic ns16550 UART U-Boot driver is removed and also migrated certain
macros to its header file for usage in device-specific drivers.

higher baudrates
Move to OMAP specific implementation of certain ops functions as the UART
prints on the serial console fail for baudrates greater than 460800.
The MDR1 register is responsible for determining the speed mode at which
the UART should operate for OMAP specific devices. The baud divisor is used
to set the UART_DLL register which is used for generation of the baud
clock in the baud rate generator. The implementation logic is similar to
how it is implemented in omap_8250_get_divisor function of 8250_omap UART
linux driver.
