This prevents the following boot-time message on any board where only the
first DC is in use, yet the DC's DT node is enabled:
stdio_add_devices: Video device failed (ret=-22)
(This happens on at least Harmony, Ventana, and likely any other Tegra20
board with display enabled other than Seaboard).
The Tegra DC's DT node represents a display controller. It may itself
drive an integrated RGB display output, or be used by some other display
controller such as HDMI. For this reason the DC node itself is not
enabled/disabled in DT; the DC itself is considered a shared resource, not
the final (board-specific) display output. The node should instantiate a
display output driver only if the rgb subnode is enabled. Other output
drivers are free to use the DC if they are enabled and their DT node
references the DC's DT node. Adapt the Tegra display drivers' bind()
routine to only bind to the DC's DT node if the RGB subnode is enabled.
Now that the display driver does the right thing, remove the workaround
for this issue from Seaboard's DT file.

The current delays in the DDR initialization routines for am33xx
architectures are sometimes not running long enough leading to DDR
init errors. On am437x, this shows up as an L3 NOC error after the
kernel boots. This is due to the timer not being initialized
properly, but instead still containing the timer init values from
the boot ROM which cause timers to expire in 1/4th the time
required.
timer_init is typically not called until board_init_r, however on
am33xx/am43xx udelay is required in sdram_init which is called
from board_init_f, so a call to timer_init is required earlier.
Note that this issue introduced in v2015.01 by:
b352dde "am33xx: Drop timer_init call from s_init".
Although this could instead fixed by reverting said commit, it
would cause timer_init to be called twice in both SPL and non-SPL

matches what is being done on omap-command and fsl-layerscape.

Commit 724219a65f "ARM: always perform per-CPU GIC init" removed some
ifdefs to unify the MULTIENTRY-vs-non-MULTIENTRY paths. However, the
wrong endif was removed. This patch adds back that missing endif, and
adds a new ifdef to match the endif the now-correctly-terminated block
used to match against. Use "git show -U25 724219a65f55" to see enough
context to make the original issue clear.
In practical terms, this makes no difference to runtime behaviour. The
code that was incorrectly compiled into the binary when ifndef MULTIENTRY
is a no-op for other cases, since branch_if_master evaluates to a hard-
coded jump. The only issues were:
- A few extra instructions were added to the binary.
- The comment on the endif at the very end of the function, indicating
which ifdef it matched, were wrong.
An alternative might be to simply fix the comment on that trailing ifdef,
but that only addresses the second point above, not the first.

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

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.

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

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".

During secure boot, Linux image along with other images are validated
using bootscript. This bootscript also needs to be validated before
it executes. This requires a header for bootscript.
When secure boot is enabled, default bootcmd is changed to first
validate bootscript using the header and then execute the script.
For ls2080, NOR memory map is different from other ARM SoCs. So a new
address on NOR is used for this bootscript header (0x583920000). The
Bootscript address is mentioned in this header along with addresses of

Implement i2c_idle_bus in driver, then setup_i2c can
be dropped for boards which enable DM_I2C/DM_GPIO/PINCTRL.
The i2c_idle_bus force bus idle flow follows setup_i2c in
arch/arm/imx-common/i2c-mxv7.c
This patch is an implementation following linux kernel patch:
"
commit 1c4b6c3bcf30d0804db0d0647d8ebeb862c6f7e5
Author: Gao Pan <b54642@freescale.com>
Date: Fri Oct 23 20:28:54 2015 +0800
i2c: imx: implement bus recovery
Implement bus recovery methods for i2c-imx so we can recover from
situations where SCL/SDA are stuck low.
Once i2c bus SCL/SDA are stuck low during transfer, config the i2c
pinctrl to gpio mode by calling pinctrl sleep set function, and then
use GPIO to emulate the i2c protocol to send nine dummy clock to recover
i2c device. After recovery, set i2c pinctrl to default group setting.
"
See Documentation/devicetree/bindings/i2c/i2c-imx.txt for detailed
description.
1. Introuduce scl_gpio/sda_gpio/bus in mxc_i2c_bus.
2. Discard the __weak attribute for i2c_idle_bus and implement it,
since we have pinctrl driver/driver model gpio driver. We can
use device tree, but not let board code to do this.
3. gpio state for mxc_i2c is not a must, but it is recommended. If
there is no gpio state, driver will give tips, but not fail.
4. The i2c controller was first probed, default pinctrl state will
be used, so when need to use gpio function, need to do
"pinctrl_select_state(dev, "gpio")" and after force bus idle,
need to switch back "pinctrl_select_state(dev, "default")".
This is example about how to use the gpio force bus
idle function:
"
&i2c1 {
clock-frequency = <100000>;
pinctrl-names = "default", "gpio";
pinctrl-0 = <&pinctrl_i2c1>;
pinctrl-1 = <&pinctrl_i2c1_gpio>;
scl-gpios = <&gpio1 28 GPIO_ACTIVE_HIGH>;
sda-gpios = <&gpio1 29 GPIO_ACTIVE_HIGH>;
status = "okay";
[....]
};
[.....]
pinctrl_i2c1_gpio: i2c1grp_gpio {
fsl,pins = <
MX6UL_PAD_UART4_TX_DATA__GPIO1_IO28 0x1b8b0
MX6UL_PAD_UART4_RX_DATA__GPIO1_IO29 0x1b8b0
>;
};

dma_addr_t holds any valid DMA address. If the DMA API only uses 32-bit
addresses, dma_addr_t need only be 32 bits wide. Bus addresses, e.g., PCI BARs,
may be wider than 32 bits, but drivers do memory-mapped I/O to ioremapped
kernel virtual addresses, so they don't care about the size of the actual
bus addresses.
Also 32 bit ARM systems with LPAE enabled can use 64bit address space, but
DMA still use 32bit address like in case of DRA7 and Keystone platforms.
This is inspired from the Linux kernel types implementation[1]

Since many platforms may need different pad configuration required
depending on variation of the platform with minor deltas, it is
easier to maintain a sub step based approach to allow for pin mux

and need to be done in IO isolation.
While we retain the older __recalibrate_iodelay function which provides
a ready sequencing, __recalibrate_iodelay_start and
__recalibrate_iodelay_end may be alternatively used now and the callers
will be responsible for the correct sequencing of operations.
