b56b9a0884 ARM: AM43xx: Change DDR3 Reset Value
The bit DDR3_RST_DEF_VAL inside CTRL_DDR_IO represents the default value
of the ddr reset value for DDR3 before the EMIF takes over. We must have
this bit set high so that on exit from DeepSleep0 within the kernel the
reset line has the proper value.

f84880f0f3 ARM: AM43xx: Write sdram_config to secure_emif_sdram_config
The register secure_emif_sdram_config in control module is copied to

order to ensure that the EMIF comes up for the correct type of DDR.

4800be4a0c ARM: AM43xx: EMIF: configure self-refresh entry delay
Per a suggestion from the hardware team, program the emif_pwr_mgmt_ctrl
and emif_pwr_mgmt_ctrl_shdw registers within the EMIF to hold the
desired delay in cycles that the EMIF waits without an access to enter
self-refresh, in this case 8192 cycles. With this, code desiring to
enter self refresh only has to toggle one bit to enable it.

1551df35f2 arm: Switch to -mno-unaligned-access when supported by the compiler
When we tell the compiler to optimize for ARMv7 (and ARMv6 for that
matter) it assumes a default of SCTRL.A being cleared and unaligned
accesses being allowed and fast at the hardware level.  We set this bit
and must pass along -mno-unaligned-access so that the compiler will
still breakdown accesses and not trigger a data abort.

To better help understand the requirements of the project with respect
to unaligned memory access, the
Documentation/unaligned-memory-access.txt file has been added as
doc/README.unaligned-memory-access.txt and is taken from the v3.14-rc1
tag of the kernel.

9e4140329e kbuild: change out-of-tree build
This commit changes the working directory
where the build process occurs.

Before this commit, build process occurred under the source
tree for both in-tree and out-of-tree build.

That's why we needed to add $(obj) prefix to all generated
files in makefiles like follows:
  $(obj)u-boot.bin:  $(obj)u-boot

Here, $(obj) is empty for in-tree build, whereas it points
to the output directory for out-of-tree build.

And our old build system changes the current working directory
with "make -C <sub-dir>" syntax when descending into the
sub-directories.

On the other hand, Kbuild uses a different idea
to handle out-of-tree build and directory descending.

The build process of Kbuild always occurs under the output tree.
When "O=dir/to/store/output/files" is given, the build system
changes the current working directory to that directory and
restarts the make.

Kbuild uses "make -f $(srctree)/scripts/Makefile.build obj=<sub-dir>"
syntax for descending into sub-directories.
(We can write it like "make $(obj)=<sub-dir>" with a shorthand.)
This means the current working directory is always the top
of the output directory.

7981449280 ARM: mx6: Add PCI express clock configuration
Split the SATA clock enabling function and add PCI express clock
enabling function. The SATA clock enabling function starts up the
100MHz SATA reference PLL in ENET_PLL register, but the code can
be re-used to enable the 125MHz PCIe reference in ENET_PLL, so pull
this code into separate function. Moreover, add the PCIe clock
enabling code.

Before this commit, all arch/arm/cpu/${CPU}/config.mk except ARMv8
had the same option:
$(call cc-option,-mshort-load-bytes,$(call cc-option,-malignment-traps,))

This commit moves it into arch/arm/config.mk.

If the compiler does not support the option,
it is ignored by $(call cc-option,...).

OPP50	300MHz
OPP100	600MHz
OPP120	720MHz
OPPTB	800MHz
OPPNT	1000MHz
According to the latest DM following is the OPP table dependencies:

	OPP50		OPP50
	OPP50 		OPP100
	OPP100		OPP50
	OPP100		OPP100
	OPP100		OPP120
So at different OPPs of MPU it is safest to lock CORE at OPP_NOM.
Following are the DPLL locking frequencies at OPP NOM:
Core locks at 1000MHz
Per locks at 960MHz
LPDDR2 locks at 266MHz
DDR3 locks at 400MHz

Touching AM33xx files also to get DPLL values specific to board but no

f33b9bd398 arm: omap3: Enable clocks for peripherals only if they are used
This patch change the per_clocks_enable() function used in OMAP3
code to enable peripherals clocks. Only required clock should be
activated. So if the board use the uart(x) as a console we need
to activate it. The Board's config should include define to enable
every subsystem that the board use. For a complete list
of affected peripherals, registers CM_FCLKEN_PER and CM_ICLKEN_PER
should be checked.
Right now the bootloader can enable and disable clocks for:
uart(x) using CONFIG_SYS_NS16550
gpio bank (x) using CONFIG_OMAP3_GPIO_X with X = { 2, 3, 4, 5, 6 }
i2c bus using CONFIG_DRIVER_OMAP34XX_I2C.

Not required gptimer(x) and mcbsp(x) for booting are disabled by default and
are not supported by any define.
Their activation need to included in the per_clocks_enable if the
peripheral is included. Not booting board should enable the peripheral
clock connected to their driver

54d022e76c ARM: DRA7/OMAP5: EMIF: Add workaround for bug 0039
When core power domain hits oswr, then DDR3 memories does not come back
while resuming. This is because when EMIF registers are lost, then the
controller takes care of copying the values from the shadow registers.
If the shadow registers are not updated with the right values, then this
results in incorrect settings while resuming. So updating the shadow registers
with the corresponding status registers here during the boot.

2c17e6d1d9 am335x: fix GPMC config for NAND and NOR SPL boot
GPMC controller is common IP to interface with both NAND and NOR flash devices.
Also, it supports max 8 chip-selects, which can be independently connected to
any of the devices.
But ROM code expects the boot-device to be connected to only chip-select[0].
Thus to resolve conflict between NOR and NAND boot. This patch:
- combines NOR and NAND configs spread in board files to common gpmc_init()
- configures GPMC based on boot-mode selected for SPL boot.

	board/ppcag/bg0900/Makefile
	drivers/bootcount/Makefile
	include/configs/omap4_common.h
	include/configs/pdnb3.h

Makefile conflicts are due to additions/removals of
object files on the ARM branch vs KBuild introduction
on the main branch. Resolution consists in adjusting
the list of object files in the main branch version.
This also applies to two files which are not listed
as conflicting but had to be modified:

	board/compulab/common/Makefile
	board/udoo/Makefile

include/configs/omap4_common.h conflicts are due to
the OMAP4 conversion to ti_armv7_common.h on the ARM
side, and CONFIG_SYS_HZ removal on the main side.
Resolution is to convert as this icludes removal of
CONFIG_SYS_HZ.

include/configs/pdnb3.h is due to a removal on ARM side.
Trivial resolution is to remove the file.

Note: 'git show' will also list two files just because
they are new:

62d206dc31 armv7: hw_data: change clock divider setting.
Clock requirement for qspi clk is 192 Mhz.
According to the below formulae,

f dpll = f ref * 2 * m /(n + 1)
clockoutx2_Hmn = f dpll / (hmn+ 1)

fref = 20 Mhz, m = 96, n = 4 gives f dpll = 768 Mhz
For clockoutx2_Hmn to be 768, hmn + 1 should be 4.

d429688754 ARM: extend non-secure switch to also go into HYP mode
For the KVM and XEN hypervisors to be usable, we need to enter the
kernel in HYP mode. Now that we already are in non-secure state,
HYP mode switching is within short reach.

While doing the non-secure switch, we have to enable the HVC
instruction and setup the HYP mode HVBAR (while still secure).

The actual switch is done by dropping back from a HYP mode handler
without actually leaving HYP mode, so we introduce a new handler
routine in our new secure exception vector table.

In the assembly switching routine we save and restore the banked LR
and SP registers around the hypercall to do the actual HYP mode
switch.

The C routine first checks whether we are in HYP mode already and
also whether the virtualization extensions are available. It also
checks whether the HYP mode switch was finally successful.
The bootm command part only calls the new function after the
non-secure switch.

ba6a169811 ARM: add SMP support for non-secure switch
Currently the non-secure switch is only done for the boot processor.
To enable full SMP support, we have to switch all secondary cores
into non-secure state also.

So we add an entry point for secondary CPUs coming out of low-power
state and make sure we put them into WFI again after having switched
to non-secure state.
For this we acknowledge and EOI the wake-up IPI, then go into WFI.
Once being kicked out of it later, we sanity check that the start
address has actually been changed (since another attempt to switch
to non-secure would block the core) and jump to the new address.

The actual CPU kick is done by sending an inter-processor interrupt
via the GIC to all CPU interfaces except the requesting processor.
The secondary cores will then setup their respective GIC CPU
interface.
While this approach is pretty universal across several ARMv7 boards,
we make this function weak in case someone needs to tweak this for
a specific board.

The way of setting the secondary's start address is board specific,
but mostly different only in the actual SMP pen address, so we also
provide a weak default implementation and just depend on the proper
address to be set in the config file.

1ef923851a ARM: add C function to switch to non-secure state
The core specific part of the work is done in the assembly routine
in nonsec_virt.S, introduced with the previous patch, but for the full
glory we need to setup the GIC distributor interface once for the
whole system, which is done in C here.
The routine is placed in arch/arm/cpu/armv7 to allow easy access from
other ARMv7 boards.

We check the availability of the security extensions first.

Since we need a safe way to access the GIC, we use the PERIPHBASE
registers on Cortex-A15 and A7 CPUs and do some sanity checks.
Boards not implementing the CBAR can override this value via a
configuration file variable.

Then we actually do the GIC enablement:
a) enable the GIC distributor, both for non-secure and secure state
   (GICD_CTLR[1:0] = 11b)
b) allow all interrupts to be handled from non-secure state
   (GICD_IGROUPRn = 0xFFFFFFFF)

The core specific GIC setup is then done in the assembly routine.

16212b594f ARM: add assembly routine to switch to non-secure state
While actually switching to non-secure state is one thing, another
part of this process is to make sure that we still have full access
to the interrupt controller (GIC).
The GIC is fully aware of secure vs. non-secure state, some
registers are banked, others may be configured to be accessible from
secure state only.
To be as generic as possible, we get the GIC memory mapped address
based on the PERIPHBASE value in the CBAR register. Since this
register is not architecturally defined, we check the MIDR before to
be from an A15 or A7.
For CPUs not having the CBAR or boards with wrong information herein
we allow providing the base address as a configuration variable.

Now that we know the GIC address, we:
a) allow private interrupts to be delivered to the core
   (GICD_IGROUPR0 = 0xFFFFFFFF)
b) enable the CPU interface (GICC_CTLR[0] = 1)
c) set the priority filter to allow non-secure interrupts
   (GICC_PMR = 0xFF)

Also we allow access to all coprocessor interfaces from non-secure
state by writing the appropriate bits in the NSACR register.

The generic timer base frequency register is only accessible from
secure state, so we have to program it now. Actually this should be
done from primary firmware before, but some boards seems to omit
this, so if needed we do this here with a board specific value.
The Versatile Express board does not need this, so we remove the
frequency from the configuration file here.

After having switched to non-secure state, we also enable the
non-secure GIC CPU interface, since this register is banked.

Since we need to call this routine also directly from the smp_pen
later (where we don't have any stack), we can only use caller saved
registers r0-r3 and r12 to not mess with the compiler.

45b940d6f9 ARM: add secure monitor handler to switch to non-secure state
A prerequisite for using virtualization is to be in HYP mode, which
requires the CPU to be in non-secure state first.
Add a new file in arch/arm/cpu/armv7 to hold a monitor handler routine
which switches the CPU to non-secure state by setting the NS and
associated bits.
According to the ARM architecture reference manual this should not be
done in SVC mode, so we have to setup a SMC handler for this.
We create a new vector table to avoid interference with other boards.
The MVBAR register will be programmed later just before the smc call.

Add a am33xx_spl_board_init (and enable the PMICs) that we may see,

case of Beaglebone White, we need to make sure we are on AC power, and
are on later than rev A1, and then we can ramp up to the PG1.0 maximum
of 720Mhz.  In the case of Beaglebone Black, we are either on PG2.0 that
supports 1GHz or PG2.1.  As PG2.0 may or may not have efuse_sma set, we
cannot rely on this probe.  In the case of the GP EVM, EVM SK and IDK we
need to rely on the efuse_sma if we are on PG2.1, and the defaults for
PG1.0/2.0.
