This patch provides a basic fdt support for zynq u-boot.
zynq-7000.dtsi-> initial arch dts file
zynq-zed.dts -> initial zed board dts file
more devices should be added in subsequent patches.u-boot build: once configuring of a board done

There is a new binary called u-boot-dtb.bin which is a u-boot

Added support to find the bootmodes by reading
slcr bootmode register. this can be helpful to
autoboot the configurations w.r.t a specified bootmode.Added this functionality on board_late_init as it's not
needed for normal initializtion part.Signed-off-by: Jagannadha Sutradharudu Teki

The toolchain sets __aarch64__ for both LE and BE. In the case of
posix_types.h we cannot reliably use config.h as that will lead to
problems. In the case of byteorder.h it's clearer to check the EB flag
being set in either case instead.Cc: David Feng

actually remove the config.h include from the posix_types.h
files, with permission from Tom Rini.

SH2 and SH2A use a common header. Both checks are not necessary.
This removes CONFIG_SH2A definition from asm/processor.h.Signed-off-by: Nobuhiro Iwamatsu
-
SH4 and SH4A are compatible. But some instructions are different from these.
In Linux kernel, It is treated as a separate CPU, but for now, I think that
there is no need to divide especially in the U-Boot.This removes CONFIG_SH4A definition from source code, SH4A is treated as SH4.
And this fix white space.Signed-off-by: Nobuhiro Iwamatsu

It is often useful to be able to save out the state from a sandbox test
run, for analysis or to restore it later to continue a test. Add generic
infrastructure for doing this using a device tree binary file. This is
a flexible tagged file format which is already supported by U-Boot, and
it supports hierarchy if needed.Signed-off-by: Simon Glass

It is useful to be able to save and restore the RAM contents of sandbox
U-Boot either for setting up tests, for later analysys, or for chaining
together multiple tests which need to keep the same memory contents.Add a function to provide a memory file for U-Boot. This is read on
start-up and written when shutting down. If the file does not exist
on start-up, it will be created when shutting down.Signed-off-by: Simon Glass

Normally when U-Boot starts with a command (-c option) it quits when the
command completes. Normally this is what is requires, since the test is
likely complete.Provide an option to jump into the console instead, so that debugging or
other tasks may be performed before quitting.Signed-off-by: Simon Glass
Signed-off-by: Simon Glass -
With sandbox, errors and problems may be reported before console_init_f()
is executed. For example, an argument may not parse correctly or U-Boot may
panic(). At present this output is swallowed so there is no indication what
is going wrong.Adjust the console to deal with a very early sandbox setup, by detecting that
there is no global_data yet, and calling os functions in that case.Signed-off-by: Simon Glass

When sandbox does a 'bootm' to run a kernel we cannot actually execute it.
So just exit sandbox, which is essentially what U-Boot does on other archs.
Also, allow sandbox to use bootm on any kernel, so that it can be used
to test booting of kernels from any architecture.Signed-off-by: Simon Glass

The execution flow becomes easier if we can return from board_init_f()
as ARM does. We can control things from start.c instead of having to
call back into that file from other places.Signed-off-by: Simon Glass

CONFIG_SYS_HZ of SH2 is not used as frequency of base timer. This is the
correct clock of CMT.
This changes from CONFIG_SYS_HZ to CONFIG_SH_CMT_CLK_FREQ, in order to use
CONFIG_SYS_HZ as clock of CMT.Signed-off-by: Nobuhiro Iwamatsu

The enable_fec_anatop_clock method should be available for all MX6
variant as it is not MX6 SoloLite specific. This moves the code out of

The macro allows easy setting in per-pin, as for example:
,----
| imx_iomux_v3_setup_pad(MX6_PAD_NANDF_D1__GPIO_2_1 | MUX_MODE_SION);
`----The IOMUX_CONFIG_SION allows for reading PAD value from PSR register.
The following quote from the datasheet:
,----
| ...
| 28.4.2.2 GPIO Write Mode
| The programming sequence for driving output signals should be as follows:
| 1. Configure IOMUX to select GPIO mode (Via IOMUXC), also enable SION if need
| to read loopback pad value through PSR
| 2. Configure GPIO direction register to output (GPIO_GDIR[GDIR] set to 1b).
| 3. Write value to data register (GPIO_DR).
| ...
`----This fixes the gpio_get_value to properly work when a GPIO is set for
output and has no conflicts.Thanks for Benoît Thébaudeau , Fabio
Estevam and Eric Bénard
for helping to properly trace this down.Signed-off-by: Otavio Salvador

Single-source clocking is new feature introduced in T1040.
In this mode, a single differential clock is supplied to the
DIFF_SYSCLK_P/N inputs to the processor, which in turn is
used to supply clocks to the sysclock, ddrclock and usbclock.So, both ddrclock and syclock are driven by same differential
sysclock in single-source clocking mode whereas in normal clocking
mode, generally separate DDRCLK and SYSCLK pins provides
reference clock for sysclock and ddrclockDDR_REFCLK_SEL rcw bit is used to determine DDR clock source
-If DDR_REFCLK_SEL rcw bit is 0, then DDR PLLs are driven in
normal clocking mode by DDR_Reference clock-If DDR_REFCLK_SEL rcw bit is 1, then DDR PLLs are driven in
single source clocking mode by DIFF_SYSCLKAdd code to determine ddrclock based on DDR_REFCLK_SEL rcw bit.

When changing LDO voltages we need to wait for the required amount of time
for the voltage to settle.Also, as the timer is still not available when arch_cpu_init() is called, we

mx6 datasheet specifies that the minimum VDDSOC at 792 MHz is 1.15 V.
Add a 25 mV margin and set it to 1.175V.This also matches the VDDSOC voltages for 792MHz operation that the kernel configures:

Since ROM may modify the LDO ramp up time according to fuse setting,
it is safer to reset the ramp up field to its default value of 00:00: 64 cycles of 24MHz clock;

02: 256 cycles of 24MHz clock;
