As no '.type' was set for save_boot_params_ret in start.S, binutils
did not track whether it was emitted as A32 or T32. By properly
marking save_boot_params_ret as a potential function entry, we can
make sure that the compiler will insert the appropriate instructions
for branching to save_boot_params_ret both for call-sites emitted as
A32 and T32.

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)/' \

- 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

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 are gated by conditionals for the

are usable on at least i.MX6SDL and i.MX6SL variants with DDR3.
Also, since only the Novena board currently uses the dynamic

Signed-off-by: Eric Nelson <eric@nelint.com>
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.
