89576072cb arc: make sure _start is in the beginning of .text section
This is important to have entry point in the beginning of .text section
because it allows simple loading and execution of U-Boot.

For example pre-bootloader loads U-Boot in memory starting from offset
0x81000000 and then just jumps to the same address.

Otherwise pre-bootloader would need to find-out where entry-point is. In
its turn if it deals with binary image of U-Boot there's no way for
pre-bootloader to get required value.

e049b772ae am33xx/ddr.c: Fix regression on DDR2 platforms
Back in fc46bae a "clean up" was introduced that intended to reconcile
some of the AM335x codepaths based on how AM43xx operates.
Unfortunately this introduced a regression on the DDR2 platforms.  This
was un-noticed on DDR3 (everything except for Beaglebone White) as we
had already populated sdram_config correctly in sequence.  This change
brings us back to the older behavior and is fine on all platforms.

Tested on Beaglebone White, Beaglebone Black and AM335x GP EVM

6102560891 Exynos5: Fix rpll_sdiv to support both peach-pit and peach-pi panels
The existing setting for rpll_sdiv generates 70.5Mhz RPLL
video clock to drive 1366x768 panel on peach_pit.

This clock rate is not sufficient to drive 1920x1080 panel on peach-pi.
So, we adjust rpll_sdiv to 3 so that it generates 141Mhz pixel clock
which can drive peach-pi LCD.

This change doesn't break peach-pit LCD since 141/2=70.5Mhz, i.e FIMD
divider at IP level will get set to 1(the required divider setting
will be calculated and set by exynos_fimd_set_clock()) and hence
peach-pit LCD still works fine.

6eb15e50f4 arc: add support for SLC (System Level Cache, AKA L2-cache)
ARCv2 cores may have built-in SLC (System Level Cache, AKA L2-cache).
This change adds functions required for controlling SLC:
 * slc_enable/disable
 * slc_flush/invalidate

For now we just disable SLC to escape DMA coherency issues until either:
 * SLC flush/invalidate is supported in DMA APIin U-Boot
 * hardware DMA coherency is implemented (that might be board specific
   so probably we'll need to have a separate Kconfig option for
   controlling SLC explicitly)

3fb8016360 arc: clean-up init procedure
Intention behind this work was elimination of as much assembly-written
code as it is possible.

In case of ARC we already have relocation fix-up implemented in C so why
don't we use C for U-Boot copying, .bss zeroing etc.

It turned out x86 uses pretty similar approach so we re-used parts of
code in "board_f.c" initially implemented for x86.

Now assembly usage during init is limited to stack- and frame-pointer
setup before and after relocation.

ae4a351ad9 arc: cache - build invalidate_icache_all() and invalidate_dcache_all()
always

Make both invalidate_icache_all() and invalidate_dcache_all() available
even if U-Boot is configured with CONFIG_SYS_DCACHE_OFF and/or
CONFIG_SYS_ICACHE_OFF.

This is useful because configuration of U-Boot may not match actual
hardware features. Real board may have cache(s) but for some reason we
may want to run U-Boot with cache(s) disabled (for example if some
peripherals work improperly with existing drivers if data cache is
enabled). So board may start with cache(s) enabled (that's the case for
ARC cores with built-in caches) but early in U-Boot we disable cache(s)
and make sure all contents of data cache gets flushed in RAM.

79d75d7527 ARM: move -march=* and -mtune= options to arch/arm/Makefile
My main motivations for this commit are:

[1] Follow the arch/arm/Makefile style of Linux Kernel

[2] Maintain compiler options systematically
  Currently, we give -march=* and -mtune=* options inconsistently:
  Only some of the CPUs pass -march=* and -mtune=* options.
  By collecting such options into the single place arch/arm/Makefile
  we can tell which options are missing at a glance.

[3] Prepare for deprecating arch/*/cpu/*/config.mk

Note:
  This commit just moves the compiler options so as not to change
  the behavior at all.  It does not care about the correctness of
  the given options.  Fox example, "-march=armv5te" might be better
  than "-march=armv4" for ARM946EJS, but it is beyond the scope this
  commit.  Also, filling the missing -march=* and -tune=* is left
  to follow-up patches.

a509161a21 ARM: UniPhier: disable L2 cache by lowlevel_init of U-Boot proper
The L2 cache is used as a temporary SRAM on SPL.
Now the secondary CPUs store the necessary code for jumping to
Linux on their L1 I-caches.  So, the L2 cache can be disabled
much earlier, at the very entry of U-Boot proper (lowlevel_init).
This makes the boot sequence clearer.
Also, as the L1 cache has been disabled by the start.S,
enable_caches() does not need to do it again.

6d8abe6a8a ARM: OMAP: Change set_pl310_ctrl_reg to be generic
set_pl310_ctrl_reg does use the Secure Monitor Call (SMC) to setup
PL310 control register, however, that is something that is generic
enough to be used for OMAP5 generation of processors as well. The only
difference being the service being invoked for the function.

So, convert the service to a macro and use a generic name (same as
that used in Linux for some consistency). While at that, also add a
data barrier which is necessary as per recommendation.

While at this, smc #0 is maintained as handcoded assembly thanks to

23b5877c64 armv8/vexpress64: make multientry conditional
While the Freescale ARMv8 board LS2085A will enter U-Boot both
on a master and a secondary (slave) CPU, this is not the common
behaviour on ARMv8 platforms. The norm is that U-Boot is entered
from the master CPU only, while the other CPUs are kept in
WFI (wait for interrupt) state.

The code determining which CPU we are running on is using the
MPIDR register, but the definition of that register varies with
platform to some extent, and handling multi-cluster platforms
(such as the Juno) will become cumbersome. It is better to only
enable the multiple entry code on machines that actually need
it and disable it by default.

Make the single entry default and add a special
ARMV8_MULTIENTRY KConfig option to be used by the
platforms that need multientry and set it for the LS2085A.
Delete all use of the CPU_RELEASE_ADDR from the Vexpress64
boards as it is just totally unused and misleading, and
make it conditional in the generic start.S code.

This makes the Juno platform start U-Boot properly.

dd09f7e73c ARM: PSCI: Rework the DT handler slightly
The way the PSCI DT update happens currently means we pull in
<asm/armv7.h> everywhere, including on ARMv8 and that in turn brings in
<asm/io.h> for some non-PSCI related things that header needs to deal
with.

To fix this, we rework the hook slightly.  A good portion of
arch/arm/cpu/armv7/virt-dt.c is common looking and I hope that when PSCI
is needed on ARMv8 we can re-use this by and large.  So rename the
current hook to psci_update_dt(), move the prototype to <asm/psci.h> and
add an #ifdef that will make re-use later easier.

114c86d826 arm: relocation: clear .bss section with arch memset if defined
For ARM architecture, enable the CONFIG_USE_ARCH_MEMSET/MEMCPY,
will highly increase the memset/memcpy performance. This is able
thanks to the ARM multiple register instructions.

Unfortunatelly the relocation is done without the cache enabled,
so it takes some time, but zeroing the BSS memory takes much more
longer, especially for the configs with big static buffers.

A quick test confirms, that the boot time improvement after using
the arch memcpy for relocation has no significant meaning.
The same test confirms that enable the memset for zeroing BSS,
reduces the boot time.

So this patch enables the arch memset for zeroing the BSS after
the relocation process. For ARM boards, this can be enabled
in board configs by defining: 'CONFIG_USE_ARCH_MEMSET'.

This was tested on Trats2.
A quick test with trace. Boot time from start to main_loop() entry:
- ~1384ms - before this change
-  ~888ms - after this change

 # nandecc sw <hamming|bch8>
where 'hamming' is still the default.

Note: we don't just use CONFIG_NAND_OMAP_ECCSCHEME as it might be set

and soon this will not be available prior to board_init_f().  Adjust the

stack be in DDR as we might have large stacks (due to Falcon Mode +
Environment).  In these cases switch to CONFIG_SPL_STACK_R.  In other
cases we had simply been setting CONFIG_SPL_STACK into SRAM.  In these
cases we no longer need to (CONFIG_SYS_INIT_SP_ADDR is used and is also

db910353a1 arm: spl: Allow board_init_r() to run with a larger stack
At present SPL uses a single stack, either CONFIG_SPL_STACK or
CONFIG_SYS_INIT_SP_ADDR. Since some SPL features (such as MMC and
environment) require a lot of stack, some boards set CONFIG_SPL_STACK to
point into SDRAM. They then set up SDRAM very early, before board_init_f(),
so that the larger stack can be used.

This is an abuse of lowlevel_init(). That function should only be used for
essential start-up code which cannot be delayed. An example of a valid use is
when only part of the SPL code is visible/executable, and the SoC must be set
up so that board_init_f() can be reached. It should not be used for SDRAM
init, console init, etc.

Add a CONFIG_SPL_STACK_R option, which allows the stack to be moved to a new
address before board_init_r() is called in SPL.

The expected SPL flow (for CONFIG_SPL_FRAMEWORK) is documented in the README.

72731118e2 apalis/colibri_t30: fix MMC/SD card detect GPIOs
This fixes the MMC/SD card detect GPIOs for Apalis T30 which got broken
by the following commit:

2b2b50bc87 "dm: tegra: dts: Use TEGRA_GPIO() macro for all GPIOs"

While at it also re-add the comments describing which particular
Apalis/Colibri pins those GPIOs are on.

cbaeceabed dm: tegra: dts: add aliases for spi on apalis_t30
All boards with a SPI interface have a suitable spi alias except Apalis
T30. Add these missing aliases just as the following commit did for the
others:

f4d7c9dd44 ARM: tegra: pinmux: support Tegra210's e_io_hv pin option
Tegra210 has a per-pin option named e_io_hv, which indicates that the
pin's input path should be configured to be 3.3v-tolerant. Add support
for this.

Note that this is very similar to previous chip's rcv_sel option.
However, since the Tegra TRM names this option differently for the
different chips, we support the new name so that the code exactly matches
the naming in the TRM, to avoid confusion.

This patch incorporates a few fixes from Tom Warren <twarren@nvidia.com>.

b2cd3d8103 ARM: tegra: pinmux: partially handle varying register layouts
Tegra210 moves some bits around in the pinmux registers. Update the code
to handle this.

This doesn't attempt to address the issues with the group-to-group varying
drive group register layout mentioned earlier. This patch handles the
SoC-to-SoC differences in the mux register layout.
