If CONFIG_OF_CONTROL is enabled, lib/fdtdec.c is compiled.
It includes <asm/gpio.h> and then <asm/gpio.h> includes
<asm/arch/gpio.h>. Consequently, all the SoCs that enable
CONFIG_OF_CONTROL must have <asm/arch/gpio.h> even if they do not
support GPIO.
In the first place, GPIO has nothing to do with OF_CONTROL.
It is wrong that lib/fdtdec.c includes GPIO functions; it should
be split into two files, FDT-common things and GPIO things.
It is, however, a pretty big work to fix that correctly.
This is a compromised commit to add a dummy <asm/arch/gpio.h>
to support OF_CONTROL for UniPhier platform. This dummy header
will be removed after FDT-GPIO stuff is fixed correctly.

This adds a fixed mode hdmi driver for the sunxi platform. The fixed
mode is a relatively safe 1024x768, more complete EDID handling is
currently not provided. Only HDMI is supported today.
This code is enabled when HPD detects an attached monitor.
Current config is such that 8MB is shaved off at the top of the RAM.
This avoids several memory handling issues, most significant is the fact
that on linux on ARM you are not allowed to remap known RAM as IO. A
clued in display driver will be able to recycle this reserved RAM in
future though.
cfbconsole was chosen as it provides the most important functionality: a
working u-boot console, allowing for the debugging of certain issues

This patch includes the latest DT sources for socfpga from the current
Linux kernel. And enables CONFIG_OF_CONTROL for the new build target
"socfpga_socrates" (the EBV SoCrates board) to make use of this new DT
support.
Until this patch, the only SoCFPGA U-Boot target in mainline is
"socfpga_cyclone5". This build target is not (yet) changed to support
DT. So nothing changes for this target. Even though the long-term
goal should be to move all SoCFPGA targets over to DT.
One of the reasons to enable DT support in SoCFPGA is, that I need to
support multiple different SPI controllers for this platform. This is
the QSPI Cadence controller and the Designware SPI master controller.
Both are implemented in the SoCFPGA. And enabling both controllers is
only possible by using the new driver model (DM). The DM SPI code
only supports DT based probing. So it was easier to move SoCFPGA to
DT than to add the (deprecated) platform-data based probing to the
DM SPI suport.
Note that the image with the dtb embedded is u-boot-dtb.img. This needs
to be used now for those DT enabled boards instead of u-boot.img.

The A31 has a new module called PRCM, or Power, Reset Control Module.
This module controls clocks and resets for RTC block modules, and also
PLL biasing in the main clock module.
This patch adds the register definitions, and also enables the clocks

This commit converts UniPhier on-chip serial driver to driver model.
Since UniPhier SoCs do not have Device Tree support, some board files
should be added under arch/arm/cpu/armv7/uniphier/ph1-*/ directories.
(Device Tree support for UniPhier platform is still under way.)
Now the base address and master clock frequency are passed from
platform data, so CONFIG_SYS_UNIPHIER_SERIAL_BASE* and
CONFIG_SYS_UNIPHIER_UART_CLK should be removed.

This patch adds the DDR3 ECC support to enable ECC in the DDR3
EMIF controller for Keystone II devices.
By default, ECC will only be enabled if RMW is supported in the
DDR EMIF controller. The entire DDR memory will be scrubbed to
zero using an EDMA channel after ECC is enabled and before
u-boot is re-located to DDR memory.
An ecc_test environment variable is added for ECC testing.
If ecc_test is set to 0, a detection of 2-bit error will reset
the device, if ecc_test is set to 1, 2-bit error detection
will not reset the device, user can still boot the kernel to
check the ECC error handling in kernel.

The EDMA3 controller’s primary purpose is to service data transfers
that you program between two memory-mapped slave endpoints on the device.
Typical usage includes, but is not limited to the following:
- Servicing software-driven paging transfers (e.g., transfers from external
memory, such as SDRAM to internal device memory, such as DSP L2 SRAM)
- Servicing event-driven peripherals, such as a serial port
- Performing sorting or sub-frame extraction of various data structures
- Offloading data transfers from the main device DSP(s)
- See the device-specific data manual for specific peripherals that are
accessible via the EDMA3 controller

Currently the network driver is used only by k2hk evm board.
The k2hk SoC contains NETCP v1.0, but Keystone2 SoCs, like k2e
contain NETCP v1.5. So driver should be able to work with such kind
of NETCP. This commit adds this opportunity. The main difference in
masks and some registers, the logic is the same, so only definitions
should be changed. To differentiate between versions add KS2_NETCP_V1_0
and KS2_NETCP_V1_5. Also remove unused and no more needed defines.

The keystone_nav driver is general driver intended to be used for
working with queue manager and pktdma for different IPs like NETCP,
AIF, FFTC, etc. So the it's API shouldn't be named like it works only
with one of them, it should be general names. The names with prefix
like netcp_* rather do for drivers/net/keystone_net.c driver. So it's
good to generalize this driver to be used for different IP's and
delete confusion with real NETCP driver.
The current netcp_* functions of keystone navigator can be used for
other settings of pktdma, not only for NETCP. The API of this driver
is used by the keystone_net driver to work with NETCP, so net driver
also should be corrected. For convenience collect pkdma

i.MX6SX ROM implements unified table sections.
The HAB function table is at offset 0x100. Update
the HAB function pointers accordingly.

The mx6sl/mx6sx has 2 OTG and 1 host. So they have name
"USBO2H_USB_BASE_ADDR" in imx-regs.h. The driver hard codes
the USB base address name to "USBOH3", which causes the driver
failed to build for mx6sl/mx6sx.
This patch uniform the address name to "USB_BASE_ADDR" for all
mx6 series.

LS1021AQDS has a variant with DDR4 slot. This patch adds a new defconfig
for this variant to enable DDR4 support. RAW timing parameters are not
added for DDR4. The board timing parameters are only tuned for single-
rank 1600 and 1800MT/s with Micron DIMM 9ASF51272AZ-2G1A1 due to DIMM
availability.

Secondary cores need to be released from holdoff by boot release
registers. With GPP bootrom, they can boot from main memory
directly. Individual spin table is used for each core. Spin table
and the boot page is reserved in device tree so OS won't overwrite.

When CONFIG_SECURE_BOOT is enabled, the signed images
like kernel and dtb can be authenticated using iMX6 CAAM.
The added command hab_auth_img can be used for HAB
authentication of images. The command takes the image
DDR location, IVT (Image Vector Table) offset inside
image as parameters. Detailed info about signing images
can be found in Freescale AppNote AN4581.

This patch implements a workaround to fix DDR3 memory issue.
The code for workaround detects PGSR0 errors and then preps for
and executes a software-controlled hard reset.In board_early_init,
where logic has been added to identify whether or not the previous
reset was a PORz. PLL initialization is skipped in the case of a
software-controlled hard reset.

This patch moves mx35 to the common timer functions added in commit
8dfafdd - Introduce common timer functions <Rob Herring>
The (removed) mx35 timer code (specifically __udelay()) could deadlock at
the 32-bit boundary of get_ticks(). get_ticks() returned a 32-bit value
cast up to a 64-bit value. If get_ticks() + tmo in __udelay() crossed
the 32-bit boundary, the while condition became unconditionally true and
locks the processor. Rather than patch the specific mx35 issues, simply
move everything over to the common code.

This is an implementation of GPIOs for Tegra that uses driver model. It has
been tested on trimslice and also using the new iotrace feature.
The implementation uses a top-level GPIO device (which has no actual GPIOS).
Under this all the banks are created as separate GPIO devices.
The GPIOs are named as per the Tegra datasheet/header files: A0..A7, B0..B7,
..., Z0..Z7, AA0..AA7, etc.
Since driver model is not yet available before relocation, or in SPL, a
special function is provided for seaboard's SPL code.
