Memory barriers are proven to be a requirement for both compiler and

For example if CPU or data bus it uses may do reordering of data

hard to debug data corruptions.
This implementation was heavily borrowed from up to date Linux kernel.

board: axs10x: Flush entire cache after programming reset vector
Now when we have support of IOC (IO-Coherency block) cahce operations
on regions are tuned to not be dummy stubs if IOC was found and enabled
in the core. That makes flush_dcache_range() useless for our purposes
here. And since we do need to flush modified reset vector to at least L2
cache (AKA SLC) so other cores will see it via its L1 instruction cache
we're using always functional flush_dcache_all() here.

tools: fix define2mk.sed to not add quotes around negative integers
The sed script, tools/scripts/define2mk.sed, converts config defines
from C headers into include/autoconf.mk for the use in Makefiles.
I found the tool adds quotes around negative integer values.
For example, at the point of the v2016.07-rc1 tag,
include/configs/microblaze-generic.h defines
#define CONFIG_BOOTDELAY -1 /* -1 disables auto-boot */
Because it is an integer option, it should be converted to:
CONFIG_BOOTDELAY=-1
But, the script actually converts it to:
CONFIG_BOOTDELAY="-1"
This is a fatal problem for the tools/moveconfig.py because it parses
include/autoconf.mk for the config defines from the board headers.
CONFIG_BOOTDELAY="-1" is considered as a string type option and it
is dropped due to the type mismatch from the entry in Kconfig.
This commit fixes the script so that the tools/moveconfig.py can
correctly convert integer options with a negative value.

tools: moveconfig: do not rely on type and default value given by users
Commit 96464badc794 ("moveconfig: Always run savedefconfig on the
moved config") changed the work flow of this tool a lot from the
original intention when this tool was designed first.
Since then, before running this tool, users must edit the Kconfig to
add the menu entries for the configs they are moving. It means users
had already specified the type and the default value for each CONFIG
via its Kconfig entry. Nevertheless, users are still required to
dictate the same type and the default value in the input file. This
is tedious to use. So, my idea here is to deprecate the latter.
Before moving forward with it, there is one issue worth mentioning;
since the savedefconfig re-sync was introduced, this tool has not
been able to move bool options with "default y". Joe sent a patch
to solve this problem about a year ago, but it was not applied for
some reasons. Now, he came back with an updated patch, so this
problem will be fixed soon.
For other use cases, I see no reason to require redundant dictation
in the input file. Instead, the tool can know the types and default
values by parsing the .config file.
This commit changes the tool to use the CONFIG names, but ignore the
types and default values given by the input file.
This commit also fixes one bug. Prior to this commit, it could not
move an integer-typed CONFIG with value 1.
For example, assume we are moving CONFIG_CONS_INDEX. Please note
this is an integer type option.
Many board headers define this CONFIG as 1.
#define CONFIG_CONS_INDEX 1
It will be converted to
CONFIG_CONS_INDEX=y
and moved to include/autoconf.mk, by the tools/scripts/define2mk.sed.
It will cause "make savedefconfig" to fail due to the type conflict.
This commit takes care of it by detecting the type and converting the
CONFIG value correctly.

armv8: ls2080aqds: Enable QSPI boot support
This patch adds QSPI boot support for LS2080AQDS board.
The QSPI boot image need to be programmed into the QSPI flash
first. Then we can switch to booting from QSPI memory space.

deployment from the location where it is stored (NOR, NAND, SD, SATA,

MC_BOOT_ENV_VAR will be null and MC will not be booted and DPL will
not be applied during U-boot booting.

sunxi: Move the SPL stack top to 0x1A000 on Allwinner A64/A80
Since the SRAM C corruption issue is now resolved on Allwinner
A64, it is possible to move the stack top to the address 0x1A000
on both A64 and A80. The boot ROM can load SPL binaries with
up to 32 KiB size on A64 (the 24 KiB SPL size limitation only
affects A10/A20), and this patch also ensures the availability
of 8 KiB stack.

Currently the AHB1 clock speed is configured as 200MHz by
the SPL, but this causes a subtle and hard to reproduce data
corruption in SRAM C (for example, this can't be easily
detected with a trivial memset/memcmp test).
For what it's worth, the Allwinner's BSP configures AHB1
as 200MHz, as can be verified by running the devmem2 tool
in the system running the Allwinner's kernel 3.10.x:
It is yet to be confirmed whether faster AHB1/AHB2 clock settings
can be used safely if we initialize the AXP803 PMIC instead of
using reset defaults. But in order to resolve the data corruption
problem right now, it's best to downclock AHB1 to a safe level.
Note that this issue only affects the SPL, which is not fully
supported on Allwinner A64 yet and it should not affect the boot0
usage (unless somebody can confirm SRAM C corruption with the
boot0 too).

spi: pic32_spi: add SPI master driver for PIC32 SoC.
This driver implements SPI protocol in master mode to communicate
with the SPI device connected on SPI bus. It handles /CS explicitly
by controlling respective pin as gpio ('cs-gpios' property in dt node)
and uses PIO mode for SPI transaction. It is configurable based
on driver-model only.
