Updates the SPL build so that when CONFIG_TI_SECURE_DEVICE
is in use (which it should be when building for secure parts),
the TI secure development package is used to create a valid
secure boot image. The u-boot SPL build processes is NOT aware
of the details of creating the boot image - all of that information
is encapsulated in the TI secure development package, which is
available from TI. More info can be found in README.ti-secure
Right now, two image types are generated, MLO and X-LOADER. The types
are important, as certain boot modes implemented by the device's ROM
boot loader require one or the other (they are not equivalent). The
output filenames are u-boot-spl_HS_MLO and u-boot-spl_HS_X-LOADER. The
u-boot-spl_HS_MLO image is also copied to a file named MLO, which is
the name that the device ROM bootloader requires for loading from the
FAT partition of an SD card (same as on non-secure devices).

as appropriate for the different boot modes. The same u-boot

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.

Due to incorrect placement of the clock gate cell in the ldb_di[x]_clk tree,

ldb_di_ipu_div divider. If the divider gets locked up, no ldb_di[x]_clk is

To fix the problem, both the new and current parent of the ldb_di_clk should

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.

Commit (20fae0a - ARM: DRA7: DDR: Enable SR in Power Management Control)
enables Self refresh mode by default and during warm reset the EMIF
contents are preserved. After warm reset EMIF sees that it is idle and
puts DDR in self-refresh. When in SR, leveling operations cannot be done
as DDR can only accept SR exit command, so its hanging during warm reset.
In order to fix this reset the power management control register before
EMIF initialization if it is a warm reset.

Current AM57xx evm supports both BeagleBoard-X15
(http://beagleboard.org/x15) and AM57xx EVM
(http://www.ti.com/tool/tmdxevm5728).
The AM572x EValuation Module(EVM) provides an affordable platform to
quickly start evaluation of Sitara. ARM Cortex-A15 AM57x Processors
(AM5728, AM5726, AM5718, AM5716) and accelerate development for HMI,
machine vision, networking, medical imaging and many other industrial
applications. This EVM is based on the same BeagleBoard-X15 Chassis
and adds mPCIe, mSATA, LCD, touchscreen, Camera, push button and TI's
wlink8 offering.
Since the EEPROM contents are compatible between the BeagleBoard-X15 and
the AM57xx-evm, we add support for the detection logic to enable
support for various user programmable scripting capability.
NOTE: U-boot configuration is currently a superset of AM57xx evm and
BeagleBoard-X15 and no additional configuration tweaking is needed.
This change also sets up the stage for future support of TI AM57xx EVMs
to the same base bootloader build.

Early clock initialization is currently done in two stages for OMAP4/5
SoCs. The first stage is the initialization of console clocks and
then we initialize basic clocks for functionality necessary for SoC
initialization and basic board functionality.
By splitting up prcm_init and centralizing this clock initialization,
we setup the code for follow on patches that can do board specific
initialization such as board detection which will depend on these
basic clocks.
As part of this change, since the early clock initialization
is centralized, we no longer need to expose the console clock
initialization.
NOTE: we change the sequence slightly by initializing console clocks
timer after the io settings are complete, but this is not expected
to have any functioanlity impact since we setup the basic IO drive
strength initialization as part of do_io_settings.

In current design, if any peripheral was assigned to both A7 and M4,
it will receive ipg_stop or ipg_wait when any of the 2 platforms
enter low power mode. We will have a risk that, if A7 enter wait,
M4 enter stop, peripheral will have chance to get ipg_stop and ipg_wait
asserted same time. Also if M4 enters stop mode, A7 will have no
chance to access the peripheral.
There are 26 peripherals affected by this IC issue:
SIM2(sim2/emvsim2)
SIM1(sim1/emvsim1)
UART1/UART2/UART3/UART4/UART5/UART6/UART7
SAI1/SAI2/SAI3
WDOG1/WDOG2/WDOG3/WDOG4
GPT1/GPT2/GPT3/GPT4
PWM1/PWM2/PWM3/PWM4
ENET1/ENET2
Software Workaround:
The solution is to set the peripherals to Domain0 by A core, since A core
in Domain0. The peripherals which will be used by M4, will be set to Domain1
by M4.
For example, A core set WDOG4 to domain0, but when M4 boots up, M4 will
set WDOG4 to domain1, because M4 will use WDOG4.
So the peripherals are not shared by them. This way requires
the uboot implemented the RDC driver and set the 26 IPs above
to domain 0 only. M4 image will set the M4 to domain 1 and
set peripheral which it will use to domain 1.
This patch enables the CONFIG_IMX_RDC and CONFIG_IMX_BOOTAUX for
i.MX7D SABRESD board, and setup the 26 IP resources to domain 0.

In that posting a LS1021 based system was locking up at about 5 minutes
after boot,but the problem was mysteriously related to the toolchain
used for building u-boot.Debugging the problem reveals a stuck

It appears Freescale's LS1021 support in u-boot erroneously sets the
64-bit ARM generic PL1 physical time CompareValue register to all-ones
with a 32-bit value.This causes the timer compare to fire 344 seconds
after u-boot configures it.Depending on how fast u-boot gets the
kernel booted,this amounts to about 5-minutes of Linux uptime before

Apparently the bug is masked by some toolchains. Perhaps this is
explained by default compiler options, word sizes, or binutils versions.
To fix the above issue, the generic physical timer is disabled
