35c547c2bc ARM: keystone2: keystone_nav: make it dependent on keystone driver
This driver is needed in case if keystone driver is used.
Currently only keystone_net driver uses it. So to avoid
redundant code compilation make the keystone_nav dependent
on keystone net driver. It also leads to compilation errors
for boards that does't use it.

fb2fcb798a ARM: omap: Fix GPMC init for OMAP3 platforms
Commit a0a37183 (ARM: omap: merge GPMC initialization code for all
platform) broke NAND on OMAP3 based platforms. I noticed this while
testing the latest 2014.07-rc version on the TAO3530 board. NAND
detection did not work with this error message:

NAND:  nand: error: Unable to find NAND settings in GPMC Configuration - quitting

As OMAP3 configs don't set CONFIG_NAND but CONFIG_NAND_CMD. the GPMC
was not initialized for NAND at all. This patch now fixes this issue.

Tested on TAO3530 board.

Deasserting the reset bit of MC GCR register releases core 0 to run.
Core 1 will be released by MC firmware. Stop bits are not touched for

the timeout setting the reset to a valid value,
the old reset value with zero is still valid
for the first access. In fact, the timeout block
loads the reset counter after a successful access.

Found on a am335x board with a FPGA connected
to the GPMC bus together with the NAND.
When the FPGA driver in kernel activates
the timeout, the system hangs at the first access

ed32522fe0 Exynos5420: DMC: Add software read leveling
Sometimes Read DQ and DQS are not in phase. Since, this
phase shift differs from board to board, we need to
calibrate it at DRAM init phase, that's read DQ calibration.
This patch adds SW Read DQ calibration routine to compensate
this skew.

c9334fcda9 DMC: exynos5420: Gate CLKM to when reading PHY_CON13
when CLKM is running.  If we stop CLKM when sampling it the glitches
all go away, so we'll do that as per Samsung suggestion.

We also check the "is it locked" bits of PHY_CON13 and loop until they
show the the value sampled actually represents a locked value.  It
doesn't appear that the glitching and "is it locked" are related, but
it seems wise to wait until the PHY tells us the value is good before
we use it.  In practice we will not loop more than a couple times (and
usually won't loop at all).

aacdd79095 Exynos5420: Remove code for enabling read leveling
This patch intends to remove all code which enables hardware read
leveling. All characterization environments may not cope up with
h/w read leveling enabled, so we must disable this.
Also, disabling h/w read leveling improves the MIF LVcc value
(LVcc value is the value at which DDR will fail to work properly).
Improving LVcc means we have enough voltage margin for MIF.
When h/w leveling is enabled, we have almost zero volatge margin.

b924d586d7 arm64: zero cntvoff_el2
Currently cntvoff_el2 is initialised with an arbitrary bag of bits
derived from the initial value of cnthctl_el2 on the current CPU. This is
somewhat odd and problematic as some of these bits are UNKNOWN at reset
and may differ across CPUs (which may cause an OS at EL1 to observe time
going backwards across CPUs).

This patch instead initialises cntvoff_el2 with xzr, giving the register
a consistent value of zero on all CPUs.

196311dc72 arm:am33xx: Rework s_init and add board_early_init_f
With the changes to the i2c framework (and adopting the omap24xx_i2c
driver to them) we can no longer call i2c functions prior to gd having
been set and cleared.  When SPL booting, this is handled by setting gd
to point to SRAM in s_init.  However in the cases where we are loaded
directly by ROM (memory mapped NOR or QSPI) we need to make use of the
normal hooks to slightly delay these calls.

87acf194a2 arm:am33xx: Make dram_init call sdram_init() in some contexts
We have two contexts for booting these platforms.  One is SPL which is
roughly: reset, cpu_init_crit, lowlevel_init, s_init, sdram_init, _main,
board_init_f from SPL, ... then U-Boot loads.  The other is a
memory-mapped XIP case (NOR or QSPI) where we do not run an SPL.  In
this case we go, roughly: reset, cpu_init_crit, lowlevel_init, s_init,
_main, regular board_init_f.

In the first case s_init will set a valid gd and then be able to call
sdram_init which in many cases will need i2c (which needs a valid gd for
gd->cur_i2c_bus).  In this second case we must (and are able to and
should) defer sdram_init() into dram_init() called by board_init_f as gd
will have been set in _main and cleared in board_init_f.

9f2ec3f543 spl: consolidate arch/arm/include/asm/arch-*/spl.h
arch/arm/include/asm/spl.h requires all SoCs to have
arch/arm/include/asm/arch-*/spl.h.

But many of them just define BOOT_DEVICE_* macros.

Those macros are used in the "switch (boot_device) { ... }"
statement in common/spl/spl.c.

So they should not be archtecture specific, but be described as
a simpile enumeration.

This commit merges most of arch/arm/include/asm/arch-*/spl.h
into arch/arm/include/asm/spl.h.

With a little more effort, arch-zynq/spl.h and arch-socfpga/spl.h
will be merged, while I am not sure about OMAP and Exynos.

a0a37183bd ARM: omap: merge GPMC initialization code for all platform
GPMC controller on TI's OMAP SoC is general purpose controller to interface
with different types of external devices like;
 - parallel NOR flash
 - parallel NAND flash
 - OneNand flash
 - SDR RAM
 - Ethernet Devices like LAN9220

Though GPMC configurations may be different for each platform depending on
clock-frequency and external device interfacing with controller. But
initialization sequence remains common across all platfoms.

Thus this patch merges gpmc_init() scattered in different arch-xx/mem.c
files into single omap-common/mem-common.c

However, actual platforms specific register config values are still sourced
from corresponding platform specific headers like;
 AM33xx: arch/arm/include/asm/arch-am33xx/mem.h
 OMAP3:  arch/arm/include/asm/arch-omap3/mem.h
 OMAP4:  arch/arm/include/asm/arch-omap4/mem.h
 OMAP4:  arch/arm/include/asm/arch-omap5/mem.h

Also, CONFIG_xx passed by board-profile decide config for which set of macros
need to be used for initialization
 CONFIG_NAND:    initialize GPMC for NAND device
 CONFIG_NOR:     initialize GPMC for NOR device
 CONFIG_ONENAND: initialize GPMC for ONENAND device

We want them to be ignored by git.
So what we should do is to always treat them as external files
rather than replacing ps7_init.c

This commit does:

 - Move a weak function ps7_init() to arch/arm/cpu/armv7/zynq/spl.c
   and delete board/xilinx/zynq/ps7_init.c

 - Compile board/xilinx/zynq/ps7_init.c only when it exists

2364e151e4 ARM: tegra: use a CPU freq that all SKUs can support
U-Boot on Tegra30 currently selects a main CPU frequency that cannot be
supported at all on some SKUs, and needs higher VDD_CPU/VDD_CORE values
on some others. This can result in unreliable operation of the main CPUs.

Resolve this by switching to a CPU frequency that can be supported by any
SKU. According to the following link, the maximum supported CPU frequency
of the slowest Tegra30 SKU is 600MHz:

repo http://nv-tegra.nvidia.com/gitweb/?p=linux-2.6.git;a=summary
branch l4t/l4t-r16-r2
path arch/arm/mach-tegra/tegra3_dvfs.c
table cpu_dvfs_table[]

According to that same table, the minimum VDD_CPU required to operate at
that frequency across all SKUs is 1.007V. Given the adjustment resolution
of the TPS65911 PMIC that's used on all Tegra30-based boards we support,
we'll end up using 1.0125V instead.

At that VDD_CPU, tegra3_get_core_floor_mv() in that same file dictates
that VDD_CORE must be at least 1.2V on all SKUs. According to
tegra_core_speedo_mv() (in tegra3_speedo.c in the same source tree),
that voltage is safe for all SKUs.

An alternative would be to port much of the code from tegra3_dvfs.c and
tegra3_speedo.c in the kernel tree mentioned above. That's more work
than I want to take on right now.

While all the currently supported boards use the same regulator chip for
VDD_CPU, different types of regulators are used for VDD_CORE. Hence, we
add some small conditional code to select how VDD_CORE is programmed. If
this becomes more complex in the future as new boards are added, or we
end up adding code to detect the SoC SKU and dynamically determine the
allowed frequency and required voltages, we should probably make this a
runtime call into a function provided by the board file and/or relevant
PMIC driver.

f6ae1ca058 S5P: Exynos: Add GPIO pin numbering and rename definitions
This patch includes following changes :
* Adds gpio pin numbering support for EXYNOS SOCs.
  To have consistent 0..n-1 GPIO numbering the banks are divided
  into different parts where ever they have holes in them.

* Rename GPIO definitions from GPIO_... to S5P_GPIO_...
  These changes were done to enable cmd_gpio for EXYNOS and
  cmd_gpio has GPIO_INPUT same as s5p_gpio driver and hence
  getting a error during compilation.

* Adds support for name to gpio conversion in s5p_gpio to enable
  gpio command EXYNOS SoCs. Function has been added to asm/gpio.h
  to decode the input gpio name to gpio number.
  Example: SMDK5420 # gpio set gpa00

79b079f35c dra7xx_evm: Add QSPI_4 support, qspiboot build target
We previously only supported QSPI_1 (single) support.  Add QSPI_4 (quad)
read support as well.  This means we can be given one of two boot device
values, but don't care which it is, so perform a fixup on the QSPI_4
value.  We add a qspiboot build target to better show how you would use
QSPI as a boot device in deployment.  When we boot from QSPI, we can
check the environment for 'boot_os' to control Falcon Mode.

8a0c6d6fa9 OMAP: common: consolidate fake USB ethernet MAC address creation
TI platforms such as OMAP5uevm, PandaBoard, use equivalent
logic to generate fake USB MAC address from device unique DIE ID.

Consolidate this to a generic location such that other TI platforms such
as BeagleBoard-XM can also use the same.

NOTE: at this point in time, I dont yet see a need for a generic dummy
ethernet MAC address creation function, but if there is a need in the

a88e55c4c6 ARM: OMAP: replace custom sr32() by standard I/O accessors
Replace the custom bit manipulation function sr32() by standard I/O
accessors.  A major motivation for this cleanup was the fact, that a
number of calls of that function resulted in 32 bit wide shift
operations on u32 data, which according to the C-ISO/IEC-9899-Standard
provokes undefined behaviour:

	6.5.7 Bitwise shift operators
	...
        If the value of the right operand is negative or is greater
        than or equal to the width of the promoted left operand, the
        behavior is undefined.

d381294aef ARM: tegra: pack pinmux data tables tighter
Use smaller fields in the Tegra pinmux structures in order to pack the
data tables into a smaller space. This saves around 1-3KB for the SPL
and around 3-8KB for the main build of U-Boot, depending on the board,
which SoC it uses, and how many pinmux table entries there are.

In order to pack PMUX_FUNC_* into a smaller space, don't hard-code the
values of PMUX_FUNC_RSVD* to values which require 16 bits to store them,
but instead let their values be assigned automatically, so they end up
fitting into 8 bits.

e296995767 ARM: tegra: pinctrl: remove duplication
Much of arch/arm/cpu/tegra*-common/pinmux.c is identical. Remove the
duplication by creating pinmux-common.c for all the identical code.

This leaves:
* arch/arm/include/asm/arch-tegra*/pinmux.h defining only the names of
  the various pins/pin groups, drive groups, and mux functions.
* arch/arm/cpu/tegra*-common/pinmux.c containing only the lookup table
  stating which pin groups support which mux functions.

The code in pinmux-common.c is semantically identical to that in the
various original pinmux.c, but had some consistency and cleanup fixes
applied during migration.

I removed the definition of struct pmux_tri_ctlr, since this is different
between SoCs (especially Tegra20 vs all others), and it's much simpler to
deal with this via the new REG/MUX_REG/... defines. spl.c, warmboot.c,
and warmboot_avp.c needed updates due to this, since they previously
hijacked this struct to encode the location of some non-pinmux registers.
Now, that code simply calculates these register addresses directly using
simple and obvious math. I like this method better irrespective of the
pinmux code cleanup anyway.

19ed7b4ecf ARM: tegra: use apb_misc.h in more places
Tegra's "APB misc" register region contains various miscellaneous
registers and the Tegra pinmux registers. Some code that touches the
misc registers currently uses struct pmux_tri_ctlr, which is intended to
be a definition of pinmux registers, rather than struct apb_misc_pp_ctrl,
which is intended to be a definition of the miscellaneous registers.
Convert all such code to use struct apb_misc_pp_ctrl, since struct
pmux_tri_ctlr goes away in the next patch.

This requires adding a missing field definition to struct
apb_misc_pp_ctrl, and moving the header into a more common location.

* Use the same PMUX_FUNC_RSVD[1-4] values, and ensure (RSVD1 & 3)==0;
  this will be assumed by pinmux_set_func() in a future patch.

Unfortunately, PMUX_FUNC_RSVD is still used in the pin macros. Use a
private define inside the driver to prevent this from causing compilaton
errors. This will be cleaned up when the pin tables are re-written in a
later patch in this series.

1a9df13d5b arm: mxs: Add support for generating signed BootStream
This patch adds the groundwork for generating signed BootStream, which

u-boot-signed.sb , since the process for generating regular non-signed
BootStream is much easier. Moreover, the signed bootstream depends on

To make things even uglier, the CST or HAB mandates a kind-of circular
dependency. The problem is, unlike the regular IVT, which is generated
by mxsimage, the IVT for signed boot must be generated by hand here due
to special demands of the CST. The U-Boot binary (or SPL binary) and IVT
are then signed by the CST as a one block. But here is the problem. The
size of the entire image (U-Boot, IVT, CST blocks) must be appended at
the end of IVT. But the size of the entire image is not known until the
CST has finished signing the U-Boot and IVT. We solve this by expecting
the CST block to be always 3904B (which it is in case two files, U-Boot
and the hand-made IVT, are signed in the CST block).

Add support for serial console into the i.MX23/i.MX28 SPL. A full,
uncrippled serial console support comes very helpful when debugging
various spectacular hardware bringup issues early in the process.
Because we do not use SPL framework, but have our own minimalistic
SPL, which is compatible with the i.MX23/i.MX28 BootROM, we do not
use preloader_console_init(), but instead use a similar function to
start the console. Nonetheless, to avoid blowing up the size of the
SPL binary, this support is enabled only if CONFIG_SPL_SERIAL_SUPPORT
is defined, which is disabled by default.

9c2c8a3129 arm: mxs: Adjust the load address of U-Boot and SPL for HAB
When using HAB, there are additional special requirements on the placement of
U-Boot and the U-Boot SPL in memory. To fullfill these, this patch moves the
U-Boot binary a little further from the begining of the DRAM, so the HAB CST
and IVT can be placed in front of the U-Boot binary. This is necessary, since
both the U-Boot and the IVT must be contained in single CST signature. To
make things worse, the IVT must be concatenated with one more entry at it's
end, that is the length of the entire CST signature, IVT and U-Boot binary
in memory. By placing the blocks in this order -- CST, IVT, U-Boot, we can
easily align them all and then produce the length field as needed.

As for the SPL, on i.MX23/i.MX28, the SPL size is limited to 32 KiB, thus
we place the IVT at 0x8000 offset, CST right past IVT and claim the size
is correct. The HAB library accepts this setup.

Finally, to make sure the vectoring in SPL still works even after moving
the SPL from 0x0 to 0x1000, we add a small function which copies the
vectoring code and tables to 0x0. This is fine, since the vectoring code
is position independent.

254d68b601 kbuild: move asm-offsets.c from SoC directory to arch/$(ARCH)/lib
U-Boot has supported two kinds of asm-offsets.h.

One is generic for all architectures and its source is located at
./lib/asm-offsets.c.

The other is SoC specific and its source is under SoC directory.
The problem here is that only boards with SoC directory can use
the asm-offsets infrastructure.
Putting asm-offsets.c right under CPU directory does not work.

Now a new demand is coming. PowerPC folks want to use asm-offsets.
But no PowerPC boards have SoC directory.

It seems inconsistent that some boards add asm-offsets.c to SoC
directoreis and some to CPU directories.
It looks more reasonable to put asm-offsets.c under arch/$(ARCH)/lib.

This commit merges asm-offsets.c under SoC directories into
arch/$(ARCH)/lib/asm-offsets.c.

By the way, I doubt the necessity of some entries in asm-offsets.c.

b97241b312 kbuild: Rename UIMAGE to MKIMAGE
U-Boot uses the 'mkimage' tool to produce various image types,
not only uImage image type. Rename the invocation name from
UIMAGE to MKIMAGE.

The following command was used to do the replacement:
git grep 'quiet_cmd_mkimage.* = UIMAGE' | cut -d : -f 1 | \
 xargs -i sed -i "s@\(quiet_cmd_mkimage\)\(.*\) = UIMAGE @\1\2 = MKIMAGE@" {}

Move the AES-128-CBC encryption function implemented in

Note that the warning is bogus, the function can never be called with invalid
'peripheral' argument. GCC just cannot analyze this.

d73f38f7ba am33xx: Rework #ifdef's around s_init for clarity
The s_init function is only called on SPL or XIP cases, so lets only
build it for them.  This makes the #if logic within the function a bit
clearer as to when we are or are not calling things, and makes it easier
to see that for example preloader_console_init isn't ever called in the
non-XIP full U-Boot case.

81724e09a0 at91sam9263ek: add mmc support
Add support for using the Atmel MCI driver on at91sam9263ek.
This change is modeled after the existing at91sam9260ek support.

Please note that this hooks up slot1 (MCI1) for SD. Not both.

Tested with at91bootstrap and u-boot on dataflash in slot 0
and fat-formatted 8GB SDHC in slot 1 on first revision
at91sam9263ek (which must use dataflash in slot0 to boot).

CONFIG_ATMEL_MCI_PORTB not tested.

cd2e46cb38 kbuild: add CONFIG_ prefix to USE_PRIVATE_LIBGCC
Before this commit, USE_PRIVATE_LIBGCC was defined in
arch-specific config.mk and referenced in
arch/$(ARCH)/lib/Makefile.

We are not happy about parsing config.mk again and again.
We have to keep the same behavior with a different way.

By adding "CONFIG_" prefix, this macro appears
in include/autoconf.mk, include/spl-autoconf.mk.
(And treating USE_PRIVATE_LIBGCC as CONFIG macro
is reasonable enough.)

Tegra SoC family defined USE_PRIVATE_LIBGCC as "yes"
in arch/arm/cpu/arm720t/tegra*/config.mk,
whereas did not define it in arch/arm/cpu/armv7/tegra*/config.mk.

It means Tegra enables PRIVATE_LIBGCC only for SPL.
We can describe the same behavior by adding

  #ifdef CONFIG_SPL_BUILD
  # define CONFIG_USE_PRIVATE_LIBGCC
  #endif

to include/configs/tegra-common.h.

716ff5ce1d ARM: tegra: simplify halt_avp()
In order to completely halt the AVP processor, we should simply write
FLOW_MODE_STOP without any extra options that allow wakeup. Amend the
code to do this.

I believe that enabling FIQ_1 and IRQ_1 allow the CPU to be awoken by
interrupts. We don't want this; if later SW wishes to use the AVP, it
should be reset and booted from scratch.

Related, the bits that were previously IRQ_1 and FIQ_1 have a slightly
different definition starting with Tegra114, so the values we're
writing don't entirely make sense there anyway.

f3026c1683 ARM: tegra: fix pmc_pwrgate_timer_mult register definition
Register pmc_pwrgate_timer_mult has a different layout on Tegra114 and
Tegra124. Reflect this in pmc.h.

Also, simply write the whole of the register in start_cpu() rather than
doing a read-modify-write; the register is simple enough that the code
can easily construct the entire desired value.
