The Allwinner A64 SoCs suffers from an arch timer implementation erratum,
where sometimes the lower 11 bits of the counter value erroneously
become all 0's or all 1's [1]. This leads to sudden jumps, both forwards and
backwards, with the latter one often showing weird behaviour.
Port the workaround proposed for Linux to U-Boot and activate it for all

This fixes crashes when accessing MMC devices (SD cards), caused by a
recent change to actually use the counter value for timeout checks.

net: Prefer command line arguments
We can call commands like dhcp and bootp without arguments or with
explicit command line arguments that really should tell the code where
to look for files instead.
Unfortunately, the current code simply overwrites command line arguments
in the dhcp case with dhcp values.
This patch allows the code to preserve the command line values if they
were set on the command line. That way the semantics are slightly more
intuitive.
The reason this patch does that by introducing a new variable is that we
can not rely on net_boot_file_name[0] being unset, as today it's
completely legal to call "dhcp" and afterwards run "tftp" and expect the
latter to repeat the same query as before. I would prefer not to break
that behavior in case anyone relies on it.

net: Add new wol command - Wake on LAN
Add a new command 'wol': Wait for an incoming Wake-on-LAN packet or
time out if no WoL packed is received.
If the WoL packet contains a password, it is saved in the environment
variable 'wolpassword' using the etherwake format (dot or colon
separated decimals).
Intended use case: a networked device should boot an alternate image.
It's attached to a network on a client site, modifying the DHCP server
configuration or setup of a tftp server is not allowed.
After power on the device waits a few seconds for a WoL packet. If a
packet is received, the device boots the alternate image. Otherwise
it boots the default image.
This method is a simple way to interact with a system via network even
if only the MAC address is known. Tools to send WoL packets are
available on all common platforms.
Some Ethernet drivers seem to pad the incoming packet. The additional
padding bytes might be recognized as Wake-on-LAN password bytes.

ARM: Introduce ability to enable invalidate of BTB with ICIALLU on Cortex-A15 for CVE-2017-5715
As recommended by Arm in [1], ACTLR[0] (Enable invalidates of BTB)
needs to be set[2] for BTB to be invalidated on ICIALLU. This needs to
be done unconditionally for Cortex-A15 processors. Provide a config
option for platforms to enable this option based on impact analysis
for products.
NOTE: This patch in itself is NOT the final solution, this requires:
a) Implementation of v7_arch_cp15_set_acr on SoCs which may not
provide direct access to ACR register.
b) Operating Systems such as Linux to provide adequate workaround in the
right locations.
c) This workaround applies to only the boot processor. It is important
to apply workaround as necessary (context-save-restore) around low
power context loss OR additional processors as necessary in either
firmware support OR elsewhere in OS.

usb: sunxi: Use proper reg_mask for clock gate, reset
Masking clock gate, reset register bits based on the
probed controller is proper only due to the assumption
that masking should start with 0 even thought the controller
has separate PHY or shared between OTG.
unfortunately these are fixed due to lack of separate

Say for example EHCI1 - EHCI3 in the datasheet (EHCI0 is for the OTG)

This patch calculated the mask, based on the register base

spi: omap3: fix claim/release bus within DM
The claim/release bus function must not reset the whole SPI core because

a non-functional SPI.
Without DM the failure didn't came up since after the spi_reset within
claim bus all the setup (wordlen, mode, ...) was called, in DM they are
called by the spi uclass.
We change now the things as following for having a working SPI instance
in DM:
- move the spi_reset(...) to the probe call in DM for having a known
hardware state after probe. Without DM we don't have a probe call, so we
issue the reset as before during the claim_bus call.
- in release bus we just reset the modulctrl to the reset-value (spi-
