The loop implemented in the code is supposed to check whether the
PL310 operation register has any bit from the mask set. Currently,
the code checks whether the PL310 operation register has any bit
set AND whether the mask is non-zero, which is incorrect. Fix the
conditional.Signed-off-by: Marek Vasut

_omap3_spi_set_wordlen() indexed the regs->channel[] array with the
old wordlen (instead of the chipselect number) when reading the current
CHCONF register value. This meant it read from the wrong memory location,
modified that value, and then wrote it back to the correct CHCONF
register. The end result is that most slave configuration settings would
be lost, such as clock divisor, clock/chipselect polarities, etc.Fixes: 77b8d04854f4 ("spi: omap3: Convert to driver model")

This patch enables CONFIG_SYS_BOOT_RAMDISK_HIGH for RISC-V
because bootm will update initrd location in DTB only if
CONFIG_SYS_BOOT_RAMDISK_HIGH is enabled. If we don't enable
this option then bootm assumes DTB already has initrd details
which is not the case most of the time.Signed-off-by: Atish Patra

This patch adds SiFive FU540 board support. For now, only
SiFive serial, SiFive PRCI, and Cadance MACB drivers are

U-Boot for S-Mode because U-Boot on SiFive FU540 will run
in S-Mode as payload of BBL or OpenSBI.Signed-off-by: Atish Patra

Currently, timer driver is bound only for hart0.
There is no mandatory requirement that hart0 should always
come up. In fact, HiFive Unleashed SoC hart0 doesn't boot
in S-mode because it only has M-mode.The timer driver should be bound for boot hart.

On 64bit systems, the DRAM top can be easily beyond 4GB and U-Boot
DMA mapping APIs will generate DMA addresses beyond 4GB. This
breaks DMA programming in 32bit DMA capable devices (such as
Cadence MACB ethernet). For example, If DRAM is more then 2GB
on QEMU sifive_u machine then Cadence MACB ethernet stops working
for U-Boot because it is a 32bit DMA capable device.To handle 32bit DMA capable devices on 64bit systems, we provide
custom implementation of board_get_usable_ram_top() which ensures
that usable ram top is not more then 4GB. This in-turn ensures
that U-Boot always runs within 4GB hence DMA addresses generated
by DMA mapping APIs will be within 4GB too.Signed-off-by: Atish Patra

The QEMU CPU support under arch/riscv is pretty much generic
and works fine for SiFive Unleashed as well. In fact, there
will be quite a few RISC-V SOCs for which QEMU CPU support
will work fine.This patch renames cpu/qemu to cpu/generic to indicate the
above fact. If there are SOC specific errata workarounds
required in cpu/generic then those can be done at runtime
in cpu/generic based on CPU vendor specific DT compatible

Pull request for the UEFI sub-system for v2019.04-rc3
A new option -e is added to the env command which allows to display and
change UEFI variables in a user friendly way.A new command efidebug is introduced to edit the UEFI boot sequence and to
display different aspects of the state of the UEFI sub-system: memory map,
loaded images, handles, drivers and devices.A bug in the UEFI boot manager is fixed.

Currently, there is no easy way to add or modify UEFI variables.
In particular, bootmgr supports BootOrder/BootXXXX variables, it is
quite hard to define them as u-boot variables because they are represented
in a complicated and encoded format.The new command, efidebug, helps address these issues and give us
more friendly interfaces:
* efidebug boot add: add BootXXXX variable
* efidebug boot rm: remove BootXXXX variable
* efidebug boot dump: display all BootXXXX variables
* efidebug boot next: set BootNext variable
* efidebug boot order: set/display a boot order (BootOrder)Signed-off-by: AKASHI Takahiro
