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.

456ecd08ec lib/crc8: Add crc start value
To make the usage of this function more flexible, lets add the CRC start
value as parameter to this function. This way it can be used by other
functions requiring different start values than 0 as well.

For non-zero CRC start values to work, I've reworked the function a bit.
The new implementation is copied from the Linux version in
drivers/i2c/i2c-core.c / i2c_smbus_pec(). Which supports non-zero
CRC stating values.

I've double-checked that the results for zero starting values are
identical to the results from the original version of this function.

20adda4cf8 bootcounter_ram: Flush dcache after data is written into SDRAM
This patch adds a call to flush_dcache_range() to bootcount_store() to

fe84ebf021 rpi: remove redundant board files
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
