8dda2e2f9e ARM: Migrate errata to Kconfig
This moves all of the current ARM errata from various header files and in to
Kconfig.  This allows for a minor amount of cleanup as we had some instances
where both a general common header file was enabling errata as well as the
board config.  We now just select these once at the higher level in Kconfig

e856bdcfb4 flash: complete CONFIG_SYS_NO_FLASH move with renaming
We repeated partial moves for CONFIG_SYS_NO_FLASH, but this is
not completed. Finish this work by the tool.

During this move, let's rename it to CONFIG_MTD_NOR_FLASH.
Actually, we have more instances of "#ifndef CONFIG_SYS_NO_FLASH"
than those of "#ifdef CONFIG_SYS_NO_FLASH".  Flipping the logic will
make the code more readable.  Besides, negative meaning symbols do
not fit in obj-$(CONFIG_...) style Makefiles.

This commit was created as follows:

[1] Edit "default n" to "default y" in the config entry in
    common/Kconfig.

[2] Run "tools/moveconfig.py -y -r HEAD SYS_NO_FLASH"

[3] Rename the instances in defconfigs by the following:
  find . -path './configs/*_defconfig' | xargs sed -i \
  -e '/CONFIG_SYS_NO_FLASH=y/d' \
  -e 's/# CONFIG_SYS_NO_FLASH is not set/CONFIG_MTD_NOR_FLASH=y/'

[4] Change the conditionals by the following:
  find . -name '*.[ch]' | xargs sed -i \
  -e 's/ifndef CONFIG_SYS_NO_FLASH/ifdef CONFIG_MTD_NOR_FLASH/' \
  -e 's/ifdef CONFIG_SYS_NO_FLASH/ifndef CONFIG_MTD_NOR_FLASH/' \
  -e 's/!defined(CONFIG_SYS_NO_FLASH)/defined(CONFIG_MTD_NOR_FLASH)/' \
  -e 's/defined(CONFIG_SYS_NO_FLASH)/!defined(CONFIG_MTD_NOR_FLASH)/'

[5] Modify the following manually
  - Rename the rest of instances
  - Remove the description from README
  - Create the new Kconfig entry in drivers/mtd/Kconfig
  - Remove the old Kconfig entry from common/Kconfig
  - Remove the garbage comments from include/configs/*.h

8e63ed518d arch: arm: update the IFC IP input clock
IFC IP clock is always a constant divisor of platform clock
pre-defined per SoC. Clock control register (CCR) used in
current implementation governs IFC IP output clock.

Update sys_info->freq_localbus to represent IFC input clock with
value constant divisor of platform clock.

91558c8153 arm: armv7: add us timer for bootstage
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)

792f186846 mx6sx: Add initial support for UDOO Neo Board
UDOO Neo Board is a development board from Seco that has three models:
 - UDOO Neo Basic
 - UDOO Neo Basic Kick Starter
 - UDOO Neo Extended
 - UDOO Neo Full

All versions are based on the i.MX6 SoloX processor.

For more details about the UDOO Neo board, please refer to:
http://www.udoo.org/udoo-neo/

This work is based on a previous commit of Francesco Montefoschi
<francesco.monte@gmail.com>:
877b71184a

Only tested on the UDOO Neo Full board.

a425bf7281 ARM: mx6: ddr: use Kconfig for inclusion of DDR calibration routines
The DDR calibration routines are gated by conditionals for the
i.MX6DQ SOCs, but with the use of the sysinfo parameter, these
are usable on at least i.MX6SDL and i.MX6SL variants with DDR3.

Also, since only the Novena board currently uses the dynamic
DDR calibration routines, these routines waste space on other
boards using SPL.

Add a KConfig entry to allow boards to selectively include the
DDR calibration routines.

48c7d4379b mx6: ddr: add routine to return DDR calibration data
Add routine mmdc_read_calibration() to return the output of DDR
calibration. This can be used for debugging or to aid in construction
of static memory configuration.

This routine will be used in a subsequent patch set adding a virtual
"mx6memcal" board, but could also be useful when gathering statistics
during an initial production run.

7f17fb7400 mx6: ddr: pass mx6_ddr_sysinfo to calibration routines
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.

b33f74ead4 mx6: ddr: allow 32 cycles for DQS gating calibration
The DDR calibration code is only setting flag DG_CMP_CYC (DQS gating sample
cycle) for the first PHY.

Set the 32-cycle flag for both PHYs and clear when done so the MPDGCTRL0
output value isn't polluted with calibration artifacts.

fea7452c15 armv7: psci: cpu_off: flush D-Cache before disable D-Cache
Before disable cache, need to first flush cache.

There maybe dirty data in D-Cache before disable D-Cache.
After disable D-Cache, the first store instructions in
psci_v7_flush_dcache_all will directly store registers
{r4-r5, r7, r9-r11, lr} to memory.
If there is dirty data before disable D-Cache,
psci_v7_flush_dcache_all will flush data to memory,
and may overwrite the memory that hold the registers
{r4-r5, r7, r9-r11, lr}.

So before disable cache, first flush D-Cache.

983e37007d arm: Introduce arch/arm/mach-omap2 for OMAP2 derivative platforms
This moves what was in arch/arm/cpu/armv7/omap-common in to
arch/arm/mach-omap2 and moves
arch/arm/cpu/armv7/{am33xx,omap3,omap4,omap5} in to arch/arm/mach-omap2
as subdirectories.  All refernces to the former locations are updated to
the current locations.  For the logic to decide what our outputs are,
consolidate the tests into a single config.mk rather than including 4.
