4b0496fe79 stm32mp1: ram: fix address issue in 2 tests
If user choose to test memory size is 1GByte (0x40000000),
memory address would overflow in test "Random" and
test "FrequencySelectivePattern".
Thus the system would hangs up when running DDR test.

132518f36b serial: stm32: add Framing error support
Add management of Bit 1 of USART_ISR = FE: Framing error
This bit is set by hardware when a de-synchronization, excessive noise
or a break character is detected. It is cleared by software, writing 1
to the FECF bit in the USART_ICR register (for stm32 after f4).

abee80d789 pinctrl: stmfx: update pinconf settings
Alignment with kernel driver.

According to the following tab (coming from STMFX datasheet), updates
have to done in stmfx_pinctrl_conf_set function:

-"type" has to be set when "bias" is configured as "pull-up or pull-down"
-PIN_CONFIG_DRIVE_PUSH_PULL should only be used when gpio is configured as
 output. There is so no need to check direction.

d7d864017d i2c: mxc_i2c: Remove i2c_idle_bus from probe
i2c_idle_bus is already used in i2c_init_transfer. So before each transfer
if the bus is not ready, the i2c_idle_bus will be used to force idle.
It is unnecessary to call it again in probe.

We found a issue when enabling i2c mux with the mxc_i2c. The mxc_i2c is probed
after mux probing. However, at this moment the mux is still in idle state not
select any port. So if we call i2c_idle_bus in probe, it will fail and cause
mxc_i2c probe failed.

a074667d52 Kconfig: Varios: Fix more SPL, TPL dependencies
Several options are presenting themselves on a various boards
where the options are clearly not used.  (ie, SPL/TPL options
when SPL or TPL are not defined)

This patch is not attempting to be a complete list of items, but
more like low hanging fruit.  In some instances, I wasn't sure
of DM was required, so I simply made them SPL or TPL.

This patch attempts to reduce some of the menuconfig noise
by defining dependencies so they don't appear when not used.

b21dcebfa6 nvme: Fix PRP Offset Invalid
When large writes take place I saw a Samsung EVO 970+ return a status
value of 0x13, PRP Offset Invalid.  I tracked this down to the
improper handling of PRP entries.  The blocks the PRP entries are
placed in cannot cross a page boundary and thus should be allocated
on page boundaries.  This is how the Linux kernel driver works.

With this patch, the PRP pool is allocated on a page boundary and
other than the very first allocation, the pool size is a multiple of
the page size.  Each page can hold (4096 / 8) - 1 entries since the
last entry must point to the next page in the pool.

there is an enable_count in clk_core_disable/enable. Introduce
enable_count to track the clk enable/disable count when
clk_enable/disable for CCF. And Initialize enable_count to 0 when
register the clk.

And clk tree dump with enable_count will be supported, it will
be easy for us to check the clk status with enable_count

This is a generic implementation. Add CONFIG_SYSRESET_CMD_POWEROFF

The config flag is transitionary, that is it can be removed after all
poweroff implementations use sysreset, and just have CMD_POWEROFF depend
on sysreset.

It seems that SYSRESET_POWER_OFF was added recently, and all previous code
used SYSRESET_POWER for poweroff. SYSRESET_POWER is supposed to be a
PMIC-level power cycle, not a poweroff.

(Comment by Simon Glass)
SYSRESET_POWER means to do a power reset (removing and reinstating all power)
SYSRESET_POWER_OFF means to turn the device off and leave it off

888e1caeae phy: add support for AM654x SERDES
Add a new SERDES driver for TI's AM654x SoC which configures
the SERDES only for PCIe. Support fo USB3 can be added later.

SERDES in am654x has three input clocks (left input, external
reference clock and right input) and two output clocks (left
output and right output) in addition to a PLL mux clock which
the SERDES uses for Clock Multiplier Unit (CMU refclock).

The PLL mux clock can select from one of the three input
clocks. The right output can select between left input and
external reference clock while the left output can select
between the right input and external reference clock.

The driver has support to select PLL mux and left/right output
mux as specified in device tree.

6912f2a8ae watchdog: omap_wdt: Disable DM watchdog support in SPL
This patch disables DM watchdog support for SPL builds and uses
the legacy omap watchdog driver on TI AM335x chipsets.

The following build error is reported if DM watchdog support was
enabled in SPL:

  CC      spl/drivers/usb/gadget/rndis.o
  LD      spl/drivers/usb/gadget/built-in.o
  LD      spl/drivers/usb/musb-new/built-in.o

  LD      spl/u-boot-spl
arm-linux-ld.bfd: u-boot-spl section .u_boot_list will not fit in region .sram
arm-linux-ld.bfd: region .sram overflowed by 440 bytes
make[1]: *** [spl/u-boot-spl] Error 1
make: *** [spl/u-boot-spl] Error 2

Adjusted WATCHDOG_RESET macro accordingly. Earlier it was pointing
to hw_watchdog_reset. Since CONFIG_WATCHDOG replaces CONFIG_HW_WATCHDOG,
now WATCHDOG_RESET macro points to watchdog_reset. This watchdog_reset
is not defined anywhere for am33xx/omap2 and needs to be defined. Fixed
this by simply calling hw_watchdog_reset in watchdog_reset.

Built and tested on AM335x device (BeagleboneBlack), compile tested for
all other AM33xx/omap2 based boards.

7659ea32a6 watchdog: omap_wdt: Convert watchdog driver to use DT and DM
This patch adds device tree and driver model watchdog support,
converts the legacy omap watchdog driver to driver model for
TI AM335x chipsets. The following compile warning is removed:

===================== WARNING ======================
This board does not use CONFIG_WDT (DM watchdog support).
Please update the board to use CONFIG_WDT before the
v2019.10 release.
Failure to update by the deadline may result in board removal.
See doc/driver-model/MIGRATION.txt for more info.
====================================================

CONFIG_HW_WATCHDOG is no more a default option for AM33XX devices
after DT/DM conversion, adjusted kconfig accordingly.

DM watchdog support is enabled by default in SPL. The SPL image
doesn't fit into SRAM because of size constraints and build breaks
with an overflow. For this reason DM watchdog support should be
disabled in SPL, driver code should be adjusted accordingly to serve
this purpose.
Built and tested on AM335x device (BeagleboneBlack), compile tested
for all other AM33xx based boards.

The only minimal functional change is that the timeout parameter is now
passed in (u64) instead of (unsigned int) from mtk_wdt_start() to
mtk_wdt_set_timeout(), preserving the original value.

b283d6ba67 fpga: altera: cyclon2: Check function pointer before calling
As already done for the 'pre' function, a check is added to not follow a
NULL pointer, if somebody has not assigned a 'post' function.

175dccd710 fpga: virtex2: Add slave serial programming support
This adds support for slave serial programming, in addition to the
previously supported slave SelectMAP mode. There are two ways that this
can be used:

-Using the clk and wdata callbacks in order to write image data one bit
at a time using pure bit-banging. This works, but is rather painfully
slow with typical image sizes.

-By specifying the wbulkdata callback instead, the image loading process
can be offloaded to SPI hardware. In this mode the clk and wdata
callbacks do not need to be specified. This allows the image to be
loaded much faster, taking only a few seconds with even relatively large
images.

Slave serial programming has been tested on the Kintex-7 series of
FPGAs.

a0549f7390 fpga: virtex2: Add additional clock cycles after DONE assertion
Some Xilinx FPGA configuration options can result in the startup
sequence extending past the end of the FPGA bitstream. Continue applying
CCLK clock cycles for 8 cycles after DONE is asserted in order to ensure
the startup sequence is complete, as recommended by Xilinx.
