With SPL_LDSCRIPT moved to Kconfig (and this being a 'string' config
node), all the lingering definitions in header files will cause
warnings/errors due to the redefinition of the configuration item.
As we don't want to pollute the defconfig files (and values should
usually be identical for entire architectures), the defaults are moved
into Kconfig. Kconfig will always pick the first default that
matches, so please keep these values at the end of each file (to allow
any board-specific Kconfig, which will be included earlier) to
override with an unconditional default setting.

To fully support DM timer in SPL and TPL, we need a few things cleaned
up and normalised:
- inclusion of the uclass and drivers should be an all-or-nothing
decision for each stage and under control of $(SPL_TPL_)TIMER
instead of having the two-level configuration with TIMER and
$(SPL_TPL_)TIMER_SUPPORT
- when $(SPL_TPL_)TIMER is enabled, the ARMv8 generic timer code can
not be compiled in
This normalises configuration to $(SPL_TPL_)TIMER and moves the config
options to drivers/timer/Kconfig (and cleans up the collateral damage
to some defconfigs that had SPL_TIMER_SUPPORT enabled).

TPL builds today don't need to call into firmware or set up the MMU
(if this changes, it should be controlled through a config option
whether to include this or not), but include the needed support code
for this anyway. By moving these unused low-level functions into
seperate function-sections, the linker can garbage-collect the unused
sections.
Note that (if DM support is enabled), there will be a call to the
cache-flushing code from alloc_priv(...) in drivers/core/device.c.
This then add 52 bytes of binary size (an increase from 20589 to 20641
bytes) compared to completely removing this code.
Even for a feature-rich TPL (including DM support as for the RK3368),
this equates to a size difference of significantly more than 10% in
TPL binary size.

Using u-boot-2017.05 on i.MX6UL we ran into following problem:
Initially U-Boot could be started normally.
If we added one random command in configuration, the newly generated
image hung at startup (last output was DRAM: 256 MiB).
We tracked this down to a data abort within relocation (relocated_code).
relocated_code in arch/arm/lib/relocate.S copies 8 bytes per loop
iteration until the source pointer is equal to __image_copy_end.
In a good case __image_copy_end was aligned to 8 bytes, so the loop
stopped as suggested, but in an errornous case __image_copy_end was
not aligned to 8 bytes, so the loop ran out of bounds and caused a
data abort exception.
This patches solves the issue by aligning __image_copy_end to 8 byte
using the linker script related to arm.
I don't know if it's the correct way to solve this, so some review would
be very appreciated.
Currently we set the entry address in the psci_cpu_on function.
However R40 has a different register for this. This resulted in
an #ifdef / #else block in psci_cpu_on, which we avoided having
in the first place.
Move this part into a separate function, defined differently for
the R40 as opposed to the other single cluster platforms.

The LS1043A rev1.1 silicon supports two types of GIC offset: 4K
alignment and 64K alignment. The bit SCFG_GIC400_ALIGN[GIC_ADDR_BIT]
is used to choose which offset will be used.
The LS1043A rev1.0 silicon only supports the CIG offset with 4K
alignment.
If GIC_ADDR_BIT bit is set, 4K alignment is used, or else 64K alignment
is used. 64K alignment is the default setting.
Overriding the weak smp_kick_all_cpus, the new impletment is able to
detect GIC offset.
The default GIC offset in kernel device tree is using 4K alignment, it
need to be fixed if 64K alignment is detected.

Up to now, there are 3 kind of SoCs under Layerscape Chassis 2,
like LS1043A, LS1046A and LS1012A. But the clocks tree has a
lot of differences, for instance, the IP modules have different
dividers to derive its clock from Platform PLL. And the core
cluster PLL and platform PLL maybe have different reference
clocks, such as LS1012A. Another problem is which clock/PLL
should be described by sys_info->freq_systembus, it is confused
in Layerscape Chissis 2.
This patch is to bind the sys_info->freq_systembus to the Platform
PLL, and handle the different divider of IP modules separately
between different SoCs, and separate reference clocks of core
cluster PLL and platform PLL.

For prepending some board specific header area to U-Boot images we
were so far including a header file with a macro definition containing
the actual header specification.
This works fine if there are just a few statements and if there is only
one alternative.
However adding more complex code quickly gets messy with this approach,
so let's just drop that intermediate macro and let the #include actually
insert the code directly.
This converts the callers and the callees, but doesn't change anything

solve issue when bootstage is used with armV7 generic timer
first call of timer_get_boot_us() use the function get_timer()
before timer initialization (arch.timer_rate_hz = 0)
=> div by 0
Commit-notes
When I activate bootstage on ARMV7 architecture with platform
using the generic armv7 timer defined in file
./arch/arm/cpu/armv7m/timer.c
I have a issue because gd->arch.timer_rate_hz = 0
For me the get_timer() function should not used before timer_init
(which initialize gd->arch.timer_rate_hz) at least for the ARMV7
timer.
But in the init sequence, the first bootstage fucntion is called
before timer_init and this function use the timer function.
For me it is a error in the generic init sequence :
mark_bootstage is called before timer_init.
static init_fnc_t init_sequence_f[] = {
....
arch_cpu_init_dm,
mark_bootstage, /* need timer, go after init dm */
...
#if defined(CONFIG_ARM) || defined(CONFIG_MIPS) || \
defined(CONFIG_BLACKFIN) || defined(CONFIG_NDS32) || \
defined(CONFIG_SPARC)
timer_init, /* initialize timer */
#endif
.......
To solve the issue for all the paltform, we can move timer_init()
call just before mark_bootstage() in this array...
It should be ok for ARMV7 but I don't sure for other platform
impacted
- the other ARM platform or ARMV7 wich don't use generic timer
- MIPS BLACKFIN NDS32 or SPARC
and I don't sure of impact for other function called
(board_early_init_f for example....)
=> This patch solve issue only in timer armv7
get_boot_us() can be called everytime without div by 0 issue
(gd->arch.timer_rate_hz is not used)

The DDR calibration routines have scattered support for bus
widths other than 64-bits:
-- The mmdc_do_write_level_calibration() routine assumes the
presence of PHY1, and
-- The mmdc_do_dqs_calibration() routine tries to determine
whether one or two DDR PHYs are active by reading MDCTL.
Since a caller of these routines must have a valid struct mx6_ddr_sysinfo
for use in calling mx6_dram_cfg(), and the bus width is available in the
"dsize" field, use this structure to inform the calibration routines which
PHYs are active.
This allows the use of the DDR calibration routines on CPU variants
like i.MX6SL that only have a single MMDC port.
