Each imx image is created by a separate sub-make and during this process
the mkimage config file is run though cpp.

The cpp output is to the same file no matter what imx image is being
created.

This means if two imx images are generated in parallel they will attempt
to independently produce the same pre-processed mkimage config file at
the same time.

Avoid the problem by making the pre-processed config file name unique
based on the imx image it will be used in.  This way each image will
create a unique config file and they won't clobber each other when run
in parallel.

This should fixed the build bug referenced in b5b0e4e3 ("imximage:
Remove failure when no IVT offset is found").

Working with HAB on the i.MX7 we've encountered a case where a board that
successfully authenticates u-boot when booting Linux via OPTEE subsequently
fails to properly bring up the RTC.

The RTC registers live in the low-power block of the Secure Non-Volatile
Storage (SNVS) block.

The root cause of the error has been traced to the HAB handing off the
SNVS-RTC in a state where HPCOMR::NPSWA_EN = 0 in other words where the
Non-Privileged Software Access Enable bit is zero. In ordinary
circumstances this is OK since we typically do not run in TZ mode, however
when we boot via HAB and enablng TrustZone, it is required to set
HPCOMR::NPSWA_EN = 1 in order for the upstream Linux driver to have
sufficient permissions to manipulate the SNVS-LP block.

On our reference board it is the difference between Linux doing this:

root@imx7s-warp-mbl:~# dmesg | grep rtc
snvs_rtc_enable read 0x00000000 from SNVS_LPLR @ 0x00000034
snvs_rtc_enable read 0x00000021 from SNVS_LPCR @ 0x00000038
snvs_rtc_enable read 0x00000000 from SNVS_HPLR @ 0x00000000

snvs_rtc 30370000.snvs:snvs-rtc-lp: setting system clock to2018-04-01 00:51:04 UTC (1522543864)

and doing this:

root@imx7s-warp-mbl:~# dmesg | grep rtc
snvs_rtc_enable read 0x00000000 from SNVS_LPLR @ 0x00000034

snvs_rtc: probe of 30370000.snvs:snvs-rtc-lp failed with error -110
hctosys: unable to open rtc device (rtc0)

Note bit 1 of LPCR is not set in the second case and is set in the first
case and that bit 31 of HPCOMR is set in the second case but not in the
first.

Setting NPSWA_EN in HPCOMR allows us to boot through enabling TrustZone
and continue onto the kernel. The kernel then has the necessary permissions
to set LPCR::SRTC_ENV (RTC enable in the LP command register) whereas in
contrast - in the failing case the non-privileged kernel cannot do so.

This patch adds a simple init_snvs() call which sets the permission-bit
called from soc.c for the i.MX7. It may be possible, safe and desirable to
perform this on other i.MX processors but for now this is only tested on
i.MX7 as working.

This patch adds hab_auth_img_or_fail() a command line function that
encapsulates a common usage of authenticate and failover, namely if

For secure-boot systems, this type of locked down behavior is important to

It's possible to script this logic but, when done over and over again the
environment starts get very complex and repetitive, reducing that script
repetition down to a command line function makes sense.

u-boot has a standard "serial#" environment variable that is suitable
for storing the iSerial number we will supply via the USB device
descriptor. serial# is automatically picked up by the disk subsystem in
u-boot - thus providing a handy unique identifier in /dev/disk/by-id as
detailed below.

Storing the hardware serial identifier in serial# means we can change the
serial# if we want before USB enumeration - thus making iSerial automatic
via OTP but overridable if necessary.

This patch reads the defined OTP fuse and sets environment variable
"serial#" to the value read.

With this patch in place the USB mass storage device will appear in
/dev/disk/by-id with a unique name based on the OTP value. For example

When the DDR calibration is enabled, a situation may happen that it
will fail on a few select boards out of a whole production lot. In
particular, after the first write leveling stage, the MPWLDECTRLx
registers will contain a value 0x1nn , for nn usually being 0x7f or
slightly lower.

What this means is that the HW write leveling detected that the DQS
rising edge on one or more bundles arrives slightly _after_ CLK and
therefore when the DDR DRAM samples CLK on the DQS rising edge, the
CLK signal is already high (cfr. AN4467 rev2 Figure 7 on page 18).

The HW write leveling then ends up adding almost an entire cycle (thus
the 0x17f) to the DQS delay, which indeed aligns it, but also triggers
subsequent calibration failure in DQS gating due to this massive offset.

There are two observations here:
- If the MPWLDECTRLx value is corrected from 0x17f to 0x0 , then the
  DQS gating passes, the entire calibration passes as well and the
  DRAM is perfectly stable even under massive load.
- When using the NXP DRAM calibrator for iMX6/7, the value 0x17f or so
  in MPWLDECTRx register is not there, but it is replaced by 0x0 as one
  would expect.

Someone from NXP finally explains why, quoting [1]:

    "
    Having said all that, the DDR Stress Test does something that we
    do not advertise to the users. The Stress Test iself looks at the
    values of the MPWLDECTRL0/1 fields before reporting results, and
    if it sees any filed with a value greater than 200/256 delay
    (reported as half-cycle = 0x1 and ABS_OFFSET > 0x48), the DDR
    Stress test will reset the Write Leveling delay for this lane
    to 0x000 and not report it in the log.

    The reason that the DDR Stress test does this is because a delay
    of more than 78% a clock cycle means that the DQS edge is arriving
    within the JEDEC tolerence of 25% of the clock edge. In most cases,
    DQS is arriving < 5% tCK of the SDCLK edge in the early case, and
    it does not make sense to delay the DQS strobe almost a full clock
    cycle and add extra latency to each Write burst just to make the
    two edges align exactly. In this case, we are guilty of making a
    decision for the customer without telling them we are doing it so
    that we don't have to provide the above explanation to every customer.
    They don't need to know it.
    "

This patch adds the correction described above, that is if the MPWLDECTRx
value is over 0x148, the value is corrected back to 0x0.

The current makefile logic disables creation of the
SPL.log/u-boot-ivt.img.log etc. files when V=1 is given on the command
line, the rationale presumably being that the user wants and gets the
information on the console.

However, from general principles, I don't think a higher V= level
should affect which build artifacts get generated (and certainly
shouldn't produce fewer). Concretely, it's also a problem that when
doing a V=1 build in a terminal, the relevant HAB blocks lines easily
drown in all the other V=1 output.

Moreover, build systems such as Yocto by default pass V=1, so in that
case the information gets hidden away in the do_compile log file, making
it nigh impossible to create a recipe for creating signed U-boot images
- I don't want to disable V=1, because having verbose output in the log
file is valuable when things go wrong, but OTOH trying to go digging in
the do_compile log file (and getting exactly the right lines) is not
pleasant to even think about.

So change the logic so that for V=0, the mkimage output is redirected
to MKIMAGEOUTPUT (which is also the current behaviour), while for any
other value of V, we _additionally_ write the information to make's
stdout, whatever that might be.
