486942184a sysreset: syscon: add support for power off
The new type sysreset 'POWER_OFF', introduced by
commit 751fed426f87 ("sysreset: Add a way to find the last reset")
is only supported for "syscon-poweroff" compatible.

For details see Linux binding:
./Documentation/devicetree/bindings/power/reset/syscon-poweroff.txt

This patch removes the support of POWER_OFF for "syscon-reboot"
and keeps only the COLD reset (for command reset support)
and it introduces the compatible "syscon-poweroff"
for the POWER_OFF case.

ca2abb75a0 spi: Avoid using malloc() in a critical function
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
is very small, perhaps less than 8.

First set of u-boot-atmel features and fixes for 2019.10 cycle

This includes the Atmel QSPI driver and support for the at91 boards.
This is the port of the driver from Linux, mostly done by Tudor Ambarus.

ef6c26d338 rtc: pcf2127: Fixed bug with rtc settings and getting error time
The previous pcf2127 RTC chip could not read and set the correct time.
When reading the data of internal registers, the read address was the
value of register plus 1. This is because this chip requires the host
to send a stop signal after setting the register address and before
reading the register data.

This patch sets the register address using dm_i2c_write and reads
the register data using the original dm_i2c_xfer in order to generate
a stop signal after the register address is set, and fixes the bug of
the original read and write time.

Prior to starting a new transfer, conditionally wait for bus to not
be busy.

Reinitialise controller as otherwise operation is not stable.

5324e8ef6c xilinx_xiic: Fix fill tx fifo loop
Comparison should be against the actual message length, not loop index.

len is used for stopping while loop, pos is position in message.
stop should be sent when entire message is sent, not when
len and pos meet.

e3b93dcee8 i2c: designware_i2c: Restore enable state after set speed
Before calling __dw_i2c_set_bus_speed(),
the I2C could already be set as ether enable or disable,
we should restore the original setting instead of enable i2c anyway.

This patch fix a bug happened in init function:
    __dw_i2c_init(){
            /* Disable i2c */
            ...
            __dw_i2c_set_bus_speed(i2c_base, NULL, speed);
            writel(slaveaddr, &i2c_base->ic_sar);
            /* Enable i2c */
    }
In this case, enable i2c inside __dw_i2c_set_bus_speed() function
will cause ic_sar write fail.

6ea31cce0b ubispl: add support for loading volumes by name
The motivation is to use the UBI atomic volume rename functionality to
allow double copy software updates on UBI. To that end the SPL is
configured to always load the same volume name (e.g. "u-boot"),
whereas a software updater always installs into the secondary volume
"u-boot_r". After successful installation, these two volume names are
switched.

This extension is protected by #ifdefs as it will somewhat slow down
loading of volumes by id. This is because the code needs to disable
the optimization of ignoring all volume ids which are not
to-be-loaded, since these can only be resolved after attaching.

This adds two vtbl related functions from Linux, which are taken from
the same kernel version as the current main U-Boot UBI code (Linux 4.2
64291f7db5bd8).
