ff9c4c535a fpga: altera: Add StratixV support
This patch adds support for programming of the StratixV FPGAs. Programming
is done in this case (board theadorable) via SPI. The board may provide
board specific code for bitstream programming.

This StratixV support will be used by the theadorable board.

704d9a645e gpio: Add DM GPIO driver for Marvell MVEBU
This patch adds a DM GPIO driver for the Marvell MVEBU SoCs. There are
other non-DM drivers that might be used on these platforms. But this
patch creates a new DM driver. Which will be used by all Armada XP/38x
boards. Other MVEBU SoC (Kirkwood / Orion) may follow once they
support DM as well.

371b9e9c39 ARM: sheevaplug: correct nand partition layout
Commit 1e3d640316 (ARM: sheevaplug: redefine MTDPARTS) changed the partition
layout (without any description why), but didn't change the offset/size to
load the kernel from or the root=/dev/mtdblockX in the bootargs.

The 3MB forseen for a kernel is furthermore too little. A 4.4 build of
mvebu_v5_defconfig is 3.6MB:

-rw-r--r-- 1 peko peko 3.6M Jan 16 20:24 uImage.kirkwood-sheevaplug

When device tree support for sheevaplug was added to the kernel in commit
ee514b381e (ARM: Kirkwood: Add dts files for Sheevaplug and eSATA
Sheevaplug) a default flash partition layout (used if mtdparts= isn't passed
on the command line / CONFIG_MTD_CMDLINE_PARTS isn't enabled) with 1MB for
u-boot / environment, 4MB for the kernel and the rest for the rootfs, so use
that layout here and adjust the kernel loading to match.

9fbb0c3aa4 sunxi: Turn satapwr on from board_init
There are 2 reasons for doing this:

1) The main reason for doing this is to move it outside of
   board/sunxi/ahci.c, so that it can be used on boards which use
   a usb<->sata chip too;
2) While doing this I realized that doing it from board_init also meant
   doing it much earlier. Some printf get_timer(0) calls show that the
   time between board_init() and scsi_init() is more then 600 ms,
   so we can drop the mdelay(500)

While at it also drop the printf("SUNXI SCSI INIT\n") AHCI init is
noisy enough by itself.

fc8991c61c sunxi: Fix gmac not working due to cpu_eth_init no longer being called
cpu_eth_init is no longer called for dm enabled eth drivers, this
was causing the sunxi gmac eth controller to no longer work in u-boot.

This commit fixes this by calling the clock, reset and pinmux setup
function from s_init() and enabling the phy power pin (if any) from
board_init().

The enabling of phy power cannot be done from s_init because it uses dm
and dm is not ready yet at this point.

Note that the mdelay is dropped as the phy gets enabled much earlier
now, so it is no longer needed.

cf6eca7ccd sunxi: Configure only LVDS pins instead of all LCD pins when LVDS interface selected
The behavior before this patch would attempt to configure the mux
setting for pins 0 to 27 on PORTD to all be setting 3 for LVDS.  The
LVDS interface actually only uses pins 18 to 27 and not pins 0 to 27
as in the parallel LCD interface.  This patch restricts the
configuration to only the relevant pins 18 to 27 on PORTD.

This was tested on a sun8i A33 tablet with an LVDS screen.  MMC1 has
the capability to use pins 2 to 7 on PORTD and the mux on those pins
was being inadvertently set to setting 3 for MMC functionality which
this patch corrects.

d085ecd61b ARM: uniphier: switch to raw U-Boot image
Now everything is done to load a raw U-Boot proper image instead of
an mkimage-processed one (as far as I tested on NAND, eMMC, NOR).

The SPL already knows the load address of the U-Boot proper without
parsing its uImage header because the load address is defined by
CONFIG_SYS_TEXT_BASE, assuming that the two images are generated from
the same build.

My main motivation of this switch is to use u-boot-with-spl.bin, a
concatenation of u-boot-spl.bin and u-boot.bin.  (I wish there were
a concatenation of u-boot-spl.bin and u-boot.img...)  Anyway, this
commit would be useful for one-shot image burn.

95a2d438c9 ARM: uniphier: fix README instruction for updating U-Boot via TFTP
Commit 3cb9abc9c5 ("ARM: uniphier: update U-Boot file names in
workflow") missed to update these two sentences.  Fix them now.

Replace u-boot-spl-dtb.bin and u-boot-dtb.img with u-boot-spl.bin
and u-boot.img, respectively.

d5cf32977f ARM: uniphier: support Debug UART
For ARM32 architecture, CONFIG_DEBUG_LL is available for early
low-level debugging (and actually UniPhier 32bit SoCs use it), but
ARM64 architecture does not support it.  Instead, CONFIG_DEBUG_UART
is available as an architecture-independent debug facility.

This commit supports it on all the UniPhier SoCs (including the new
ARMv8 SoCs), which is very useful for new SoC bringups.

650aedbfc0 ARM: uniphier: add System Control register macros for ARMv8 SoCs
The System Control block moved to a completely different register
map for ARMv8 SoCs, so it cannot be shared with the ARM 32-bit ones.
Define register macros in a new header file.

f6c65bc2fa ARM: uniphier: enable DDR PHY parameter dump commands by default
These commands are not necessarily needed for usual operations
(they are useful in case of DDR memory trouble), but enabling them
by default would be nice in terms of the compilation test coverage.
They are small enough, so limited impact on the memory footprint.

36223f5de8 ARM: uniphier: add work-around to support Micro Support Card v3.6.10
Due to some hardware guy's awful work, this version is not compatible
with v3.6: the logic of BIT(0) of the reset logic is inverted! (and
v3.6.10 is horribly wrong in multiple ways), but this is what we have
to solve now.

The v3.6 expects 0x0000 set to the register for reset de-assertion,
while v3.6 does 0x0001.

This commit (ab)uses another bug of v3.6.10 to work around the issue.
The UniPhier System Bus is a 16-bit bus, which this support card is
connected to.  A 32-bit write to the bus (writel() function call) is
divided into two 16-bit write transactions, with LSB the first.  What
is amazing for v3.6.10 is that access to address 4N + 2 goes to 4N
(Jesus Christ!).

For clarification, things are like this:

    writel(0x00010000, MICRO_SUPPORT_CARD_RESET);

is done with two bus transactions as follows

    [1] write 0x0000 to address MICRO_SUPPORT_CARD
    [2] write 0x0001 to address MICRO_SUPPORT_CARD + 2

For v3.6, [1] is written to the register and [2] is correctly ignored
because there is nothing at the address MICRO_SUPPORT_CARD + 2.  This
is what we expect.

For v3.6.10, [1] is written to the reset register and then [2] is
over-written to the same register due to the bus access bug.

For the latter, it produces a glitch signal to the BIT[0], so the
device state is lost due to the reset pulse.  This solution only
works for the start-up code.
