We have to build correct images suitable for QSPI, thus have to call
lspbl_spi_image instead of lspbl_image. In lowlevel code call the
xload function which detects the bootsource rather than hardcoding
SD/MMC.

This unifies the two different pbi files. With our approach for QSPI
booting differences in the pbi files are not necessary:
- We do not do execute in place for QSPI, so we do not need different
image execution addresses
- Setting up the QSPI clock doesn't hurt even for SD boot

Do the UART initialization after the SoC specific lowlevel setup and
print the usual '>' when early debuging is enabled. To let this go out
properly it seems we have to wait a small amount of time beforehand.

use bbu_register_std_file_update() for updating to MMC and QSPI.

Booting Layerscape from QSPI is a bit tricky and the approach we take is
different from the one U-Boot has taken, so it's worth writing and
reading the following explanation.
The QSPI controller can map the Flash contents into the memory space (On
LS1046a at 0x40000000). The PBL unit uses this to read the RCW from this
memory window. The Layerscape SoCs have a PowerPC history, so it seemed
appropriate for the designers to let the QSPI controller operate in
big endian mode by default. To let the SoC see the correct RCW we have
to write the RCW and PBI data with be64 endianess. Our PBL image tool
pokes the initial binary into the SoC internal SRAM using PBI data as
done with SD/MMC boot aswell. barebox then changes the QSPI controller
endianess to le64 to properly read the barebox binary (placed at an
flash offset of 128KiB, so found in memory at 0x40020000) into SDRAM and
jumps to it.
U-Boot has another approach. Here the initial binary is executed in
place directly at 0x40100000. This means the QSPI controller endianess
must be swapped inside the PBI data. This has the effect that the whole
RCW/PBI data must be 64bit endianess swapped *except* the very last word
of the PBI data which contains the CRC command and is read already with
changed endianess. As a conclusion when porting QSPI PBI files from U-Boot
to barebox skip commands changing the endianess in the QSPI controller
and make sure the image is executed in internal SRAM and not in the
Flash memory window.
Lines like this should be removed:
09550000 000f400c
This sets the binary execution address:
09570604 40100000
For barebox it should be changed to 0x10000000.
As a result the PBI files can probably be unified between SD and QSPI
boot.

The optimized find bit functions are only implemented for 32 bit and are
not built on aarch64 systems. Therefore, for example bootchooser cannot
be build for aarch64.
Select the generic find_bit implementations on aarch64.
As the decision, if lib64 or lib32 is build or not, directly depends on
CPU_V8, the generic implementation also should be used if CPU_V8 is
selected.

The condition was introduced in 4e6e8f73e9 ("ARM: imx6: don't
execute IPU QoS setup on MX6 SX/SL"), but instead it bails at
the Solo, not the SX and SL.
The original intent was most probably to add an exception for
the i.MX6 Solo as well, so everything else is skipped, including
the SX, SL and now the UL and ULL. Fix the code to reflect this.
On the SX, SL, UL, ULL, this now avoids writes to memory, which
isn't described in the datasheets. On the S, it now configures
the QoS settings.

In the device tree, the clock controller is a subnode of the firmware
node. Devices refer to the clocks by an id that is shared between the
ATF and the driver.
While the bindings for the clock controller are already upstream, the
device in mainline Linux does not use them, yet. Add them in the Barebox
device tree for now.

barebox_arm_reset_vector() is a global function but we never provided a

Since __imx_cpu_type won't be initialized until
imx_init()@postcore_initcall is executed cpu_is_mx8mq() will only work
correctly at core_initcall level so long as imx_cpu_type does not
resolve into __imx_cpu_type. This is currently the case and
imx8mq_init_syscnt_frequency() works as expected, but it probably
won't be in the future.
To avoid this problem introduce imx8mq_cpu_lowlevel_init() and do
system counter frequency initialization there. Also convert all of the
i.MX8MQ boards to use this new function.

We need to make sure that CNTFRQ is initialized before corresponding
clocksource driver tries to use it, otherwise we'll end up crashing
due to division by zero.
We can't convert imx7_timer_init() to be an initcall since it is an
i.MX7 specific task, but CPU type information won't be availible until
after imx_init() gets executed at postcore_initcall() level. To solve
this move all of the necessary code to be a part of
imx7_cpu_lowlevel_init().
Note, that original code both hardcoded frequency value to 8MHz as
well as tried to write it to the first element of the frequency mode
table which appears to be read-only on i.MX7. So while we are at it,
simplify the code by adding set_cntfrq() implementation for ARMv7 and
copy the code we already using for i.MX8MQ.
