0297bd1106 arm: mx5: Fix NAND image generation
The echo -ne "\xNN" does not work in certain bourne-compatible shells, like
dash. The recommended way of hex->char conversion is using printf(1), but
there is a pitfall here. The GNU printf does support "\xNN" format, but
according to the opengroup documentation, this is not part of POSIX. The
POSIX printf only defines "\NNN" where N is octal. Thus, for the sake of
compatibility, we use that.

724219a65f ARM: always perform per-CPU GIC init
The current code in ARMv8's lowlevel_init() skips the per-CPU GIC
initialization ifndef CONFIG_ARMV8_MULTIENTRY. However, the per-CPU init
should always occur; it's just the one-time init that should only happen
on the master.

Once this consideration is taken into account, the only difference between
the paths when CONFIG_ARMV8_MULTIENTRY is undefined/defined is the use of
branch_if_slave. Naively, any unified code would need to invoke this
conditionally upon ifdef CONFIG_ARMV8_MULTIENTRY. However, branch_if_slave
already checks CONFIG_ARMV8_MULTIENTRY and does nothing if it isn't
defined, so we don't even need that ifdef at the call site.

e361421430 ARM: dts: dra7xx: am57xx: fix cd-gpios definition as per hardware design and dt binding docs
As per mmc device tree binding documentation card detect gpio has
to be active low signal. When a hardware is designed with active
high card detect, gpio polarity has to be changed with
cd-inverted dt property.

In DRA72x and AM57xx EVMs the card detect gpio is designed as
active low gpio. So correcting the dt card detect gpio
definition.

c09d29057a arm: Replace v7_maint_dcache_all(ARMV7_DCACHE_CLEAN_INVAL_ALL) with asm code
v7_maint_dcache_all() does not work reliable when build with gcc6,
see: https://bugzilla.redhat.com/show_bug.cgi?id=1318788

While debugging this I learned that v7_maint_dcache_all() is unreliable
when build with gcc5 too when it is marked as noinline.

This commit fixes the reliability issues by replacing the C-code with
the ready to use asm implementation from the kernel.

Given that this code when written as C-code clearly is quite fragile
(also see the existing comments about the C-code being the way it is
 to get optimal assembly) and that we have a proven asm alternative,
I believe that this is the best solution.

Note that we actually already had a copy of the kernel's
v7_flush_dcache_all() before this commit in
arch/arm/mach-uniphier/arm32/lowlevel_init.S.

This commit moves that code arch/arm/cpu/armv7/cache_v7_asm.S, renames
it to __v7_flush_dcache_all(), and adds a v7_flush_dcache_all() wrapper
which saves / restores the clobbered registers for use from C-code.

Now that rpi_*defconfig and Kconfig (rather than the config header file)
provide the identity of the build, we don't need to separate config
headers and board directories for each RPi variant. Set CONFIG_SYS_BOARD
and CONFIG_SYS_CONFIG_NAME so that we can get rid of the duplication. This
requires a tiny number of extra ifdefs in the config header.

The only disadvantage of this approach is that the $board/$board_name
environment variables aren't as descriptive as they used to be. This isn't
really an issue because those only exist to allow scripts to create DTB
filenames at runtime. However, the RPi board code already sets $fdtfile to
something more accurate based on FW-reported board ID anyway.

While at it, unify some Kconfig select options, and add a MAINTAINERS
entry for bcm283x too.

d22a765755 ARM: add Raspberry Pi 3 64-bit config
On all Pis so far, the VC FW provides a short stub to set up the ARM CPU
before entering the kernel (a/k/a U-Boot for us). This feature is not
currently supported by the VC FW when booting in 64-bit mode. However,
this feature will likely appear in the near future, and this U-Boot port
assumes that such a feature is in place. Without that feature, or a
temporary workaround described below, U-Boot will not boot.

Once the VC FW does provide the ARM stub, u-boot.bin built for rpi_3 can
be used drectly as kernel7.img, in the same way as any other RPi port. The
following config.txt is required:

    # Fix mini UART input frequency, and setup/enable up the UART.
    # Without this option, U-Boot will not boot, even if you don't care
    # about the serial console. This option will always be required for
    # all RPi3 use-cases, unless the PL011 UART is used, which is not
    # yet supported by rpi_3* builds of U-Boot.
    enable_uart=1
    # Boot in AArch64 (64-bit) mode.
    # It is possible that a future VC FW will remove the need for this
    # option, instead auto-setting 32-/64-bit mode based on the "kernel"
    # filename present on the SD card.
    arm_control=0x200

Prior to the VC FW providing the ARM boot stub, you can use the following
steps to build an equivalent stub into the U-Boot binary:

git clone https://github.com/swarren/rpi-3-aarch64-demo.git \
    ../rpi-3-aarch64-demo
(cd ../rpi-3-aarch64-demo && ./build.sh)
Build U-Boot for rpi_3 in the usual way
cat ../rpi-3-aarch64-demo/armstub64.bin u-boot.bin > u-boot.bin.stubbed
Use u-boot.bin.stubbed as kernel7.img on the Pi SD card.

In this case, the following additional entries are required in config.txt:

    # Tell the FW to load the kernel image at address 0, the reset vector.
    kernel_old=1

f031f501ef rpi: BCM2837 and Raspberry Pi 3 32-bit support
The Raspberry Pi 3 contains a BCM2837 SoC. The BCM2837 is a BCM2836 with
the CPU complex swapped out for a quad-core ARMv8. This can operate in 32-
or 64-bit mode. 32-bit mode is the current default selected by the
VideoCore firmware on the Raspberry Pi 3. This patch adds a 32-bit port of
U-Boot for the Raspberry Pi 3.

>From U-Boot's perspective, the only delta between the RPi 2 and RPi 3 is a
change in usage of the SoC UARTs. On all previous Pis, the PL011 was the
only UART in use. The Raspberry Pi 3 adds a Bluetooth module which uses a
UART to connect to the SoC. By default, the PL011 is used for this purpose
since it has larger FIFOs than the other "mini" UART. However, this can
be configured via the VideoCore firmware's config.txt file. This patch
hard-codes use of the mini UART in the RPi 3 port. If your system uses the
PL011 UART for the console even on the RPi 3, please use the RPi 2 U-Boot
port instead. A future change might determine which UART to use at
run-time, thus allowing the RPi 2 and RPi 3 (32-bit) ports to be squashed
together.

The mini UART has some limitations. One externally visible issue in the
BCM2837 integration is that the UART divides the SoC's "core clock" to
generate the baud rate. The core clock is typically variable, and under
control of the VideoCore firmware for thermal management reasons. If the
VC FW does modify the core clock rate, UART communication will be
corrupted since the baud rate will vary from the expected value. This was
not an issue for the PL011 UART, since it is fed by a fixed 3MHz clock. To
work around this, the VideoCore firmware can be told not to modify the SoC
core clock. However, the only way this can happen and be thermally safe is
to limit the core clock to a low/minimum frequency. This leaves
performance on the table for use-cases that don't care about a UART
console. Consequently, use of the mini UART console must be explicitly
requested by entering the following line into config.txt:

    enable_uart=1

A recent version of the VC firmware is required to ensure that the mini
UART is fully and correctly initialized by the VC FW; at least
firmware.git 046effa13ebc "firmware: arm_loader: emmc clock depends on
core clock See: https://github.com/raspberrypi/firmware/issues/572".

NOTE: Few of these might have default configurations, however,
since most are software configurable, it is better to explicitly
configure the system to have a known default state.

Without programming these, we end up seeing lack of coherency on certain
peripherals resulting in inexplicable failures (such as USB peripheral's
DMA data not appearing on ARM etc and weird workarounds being done by
drivers including cache flushes which tend to have system wide
performance impact).

By marking these segments as shared, we also ensure SoC wide coherency
is enabled.
