528915c717 imx: Fix potential lmb memory overwritten by stack
At default, u-boot reserves the memory from SP - 4KB to DRAM end for
lmb in arch_lmb_reserve. So lmb won't allocate any memory from it.
But we found the 4K gap for SP is not enough now, because some FDT
updating operations are added in our u-boot before jumping to kernel,
which needs larger stack. This causes the lmb allocated memory is overwritten
by stack.

Fix the issue by implementing the board_lmb_reserve to reserve from
SP - 16KB to memory end for lmb.

b2ca8907d9 imx: hab: Convert non-NULL IVT DCD pointer warning to an error
The following NXP application notes and manual recommend to ensure the
IVT DCD pointer is Null prior to calling HAB API authenticate_image()
function:

- AN12263: HABv4 RVT Guidelines and Recommendations
- AN4581: Secure Boot on i.MX50, i.MX53, i.MX 6 and i.MX7 Series using
  HABv4
- CST docs: High Assurance Boot Version 4 Application Programming
  Interface Reference Manual

Commit ca89df7dd4 ("imx: hab: Convert DCD non-NULL error to warning")
converted DCD non-NULL error to warning due to the lack of documentation
at the time of first patch submission. We have warned U-Boot users since
v2018.03, and it makes sense now to follow the NXP recommendation to
ensure the IVT DCD pointer is Null.

DCD commands should only be present in the initial boot image loaded by
the SoC ROM. Starting in HAB v4.3.7 the HAB code  will generate an error
if a DCD pointer is present in an image being authenticated by calling the
HAB RVT API. Older versions of HAB will process and run DCD if it is
present, and this could lead to an incorrect authentication boot flow.

ea91031b22 imx: hab: extend hab_auth_img to calculate ivt_offset
Current implementation of hab_auth_img command needs ivt_offset to
authenticate the image. But ivt header is placed at the end of image
date after padding.

This leaves the usage of hab_auth_img command to fixed size or static
offset for ivt header. New function "get_image_ivt_offset" is introduced
to find the ivt offset during runtime. The case conditional check in this
function is same as boot_get_kernel in common/bootm.c

With this variable length image e.g. FIT image with any random size can
have IVT at the end and ivt_offset option can be left optional

Can be used as "hab_auth_img $loadaddr $filesize" from u-boot script

e246bfcfe2 SPL: Add HAB image authentication to FIT
Introduce two board level callback functions to FIT image loading process, and
a SPL_FIT_FOUND flag to differentiate FIT image or RAW image.

Implement functions in imx common SPL codes to call HAB funtion
to authenticate the FIT image. Generally, we have to sign multiple regions
in FIT image:
1. Sign FIT FDT data (configuration)
2. Sign FIT external data (Sub-images)

Because the CSF supports to sign multiple memory blocks, so that we can use one
signature to cover all regions in FIT image and only authenticate once.
The authentication should be done after the entire FIT image is loaded into
memory including all sub-images.
We use "-p" option to generate FIT image to reserve a space for FIT IVT
and FIT CSF, also this help to fix the offset of the external data (u-boot-nodtb.bin,
ATF, u-boot DTB).

68e7410fa2 imx: bootaux: fix stack and pc assignment on 64-bit platforms
Using ulong is wrong as its size depends on the Host CPU architecture
(32-bit vs. 64-bit) although the Cortex-M4 is always 32-bit.

Without this patch, the stack and PC are obviously wrong and it
generates an abort when used on 64-bit processors such as the i.MX8MQ.

We can have the case where u-boot is launched after some other low level
enabler, like for example when u-boot runs after arm-trusted-firmware

some IP blocks even because we may no longer have the permission for that.

So, if the config option to skip low level init is set disable also timer,

This patch adds system suspend/resume support,
when linux kernel enters deep sleep mode, SoC will go
into below mode:

 - CA7 platform goes into STOP mode;
 - SoC goes into DSM mode;
 - DDR goes into self-refresh mode;
 - CPU0/SCU will be powered down.

When wake up event arrives:

 - SoC DSM mdoe exits;
 - CA7 platform exit STOP mode, SCU/CPU0 power up;
 - Invalidate L1 cache;
 - DDR exit self-refresh mode;
 - Do secure monitor mode related initialization;
 - Jump to linux kernel resume entry.

Belwo is the log of 1 iteration of system suspend/resume:

[  338.824862] PM: suspend entry (deep)

The resume entry function has to initialize stack pointer before calling

invalidate L1 cache must be done in secure section as well, so this
patch also adds assembly code back and keep it as simple as possible.

c5d548a9f8 env: common: accept flags on reset to default env
The function set_default_env() sets the hashtable flags for import_r().
Formally set_default_env() doesn't accept flags from its callers. In
practice the caller can (un)set the H_INTERACTIVE flag, but it has to be
done using the first character of the function's string argument. Other
flags like H_FORCE can't be set by the caller.

Change the function to accept flags argument. The benefits are:
1. The caller will have to explicitly set the H_INTERACTIVE flag,
   instead of un-setting it using a special char in a string.
2. Add the ability to propagate flags from the caller to himport(),
   especially the H_FORCE flag from do_env_default() in nvedit.c that
   currently gets ignored for "env default -a -f" commands.
3. Flags and messages will not be coupled together. A caller will be
   able to set flags without passing a string and vice versa.

Please note:
The propagation of H_FORCE from do_env_default() does not introduce any
functional changes, because currently himport_r() is set to destroy the
old environment regardless if H_FORCE flag is set or not. More changes
are needed to utilize the propagation of H_FORCE.

83d290c56f SPDX: Convert all of our single license tags to Linux Kernel style
When U-Boot started using SPDX tags we were among the early adopters and
there weren't a lot of other examples to borrow from.  So we picked the
area of the file that usually had a full license text and replaced it
with an appropriate SPDX-License-Identifier: entry.  Since then, the
Linux Kernel has adopted SPDX tags and they place it as the very first
line in a file (except where shebangs are used, then it's second line)
and with slightly different comment styles than us.

In part due to community overlap, in part due to better tag visibility
and in part for other minor reasons, switch over to that style.

This commit changes all instances where we have a single declared
license in the tag as both the before and after are identical in tag
contents.  There's also a few places where I found we did not have a tag
and have introduced one.

f916757300 imx: Create distinct pre-processed mkimage config files
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").

723f8359c1 imx: mx7: snvs: Add an SNVS init routine
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_enable read 0x80002100 from SNVS_HPCOMR @ 0x00000004

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_enable read 0x00000001 from SNVS_HPLR @ 0x00000000
snvs_rtc_enable read 0x00002020 from SNVS_HPCOMR @ 0x00000004
snvs_rtc 30370000.snvs:snvs-rtc-lp: failed to enable rtc -110
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.

49e6242673 imx: hab: Provide hab_auth_img_or_fail command
This patch adds hab_auth_img_or_fail() a command line function that
encapsulates a common usage of authenticate and failover, namely if
authenticate image fails, then drop to BootROM USB recovery mode.

For secure-boot systems, this type of locked down behavior is important to
ensure no unsigned images can be run.

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.

14eeb683a8 ARM: mx6: ddr: Add write leveling correction code
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.

Similarly to imx6, before reading the boot device, first check
bmode to see if the serial downloader has been selected
explicitly, then check whether the serial downloader has been
activated due to unbootable primary boot devices (e.g. empty eMMC).

If the serial downloader is activated, return BOOT_DEVICE_BOARD.
This allows SPL with SDP support to wait for the U-Boot image
to be loaded via the serial download protocol using imx_usb_loader.

ca89df7dd4 imx: hab: Convert DCD non-NULL error to warning
commit 8c4037a09a ("imx: hab: Ensure the IVT DCD pointer is Null prior
to calling HAB authenticate function.") makes the DCD field being NULL a
dependency.

This change though will break loading and executing of existing pre-signed
binaries on a u-boot update i.e. if this change is deployed on a board you
will be forced to redo all images on that board to NULL out the DCD.

There is no prior guidance from NXP that the DCD must be NULL similarly
public guidance on usage of the HAB doesn't call out this NULL dependency
(see boundary devices link).

Since later SoCs will reject a non-NULL DCD there's no reason to make a
NULL DCD a requirement, however if there is an actual dependency for later
SoCs the appropriate fix would be to do SoC version checking.

Earlier SoCs are capable (and happy) to authenticate images with non-NULL
DCDs, we should not be forcing this change on downstream users -
particularly if it means those users now must rewrite their build systems
and/or redeploy signed images in the field.

Fixes: 8c4037a09a ("imx: hab: Ensure the IVT DCD pointer is Null prior
to calling HAB authenticate function.")

314d9f7e3e imx: syscounter: make sure asm is volatile
Without the volatile attribute, compilers are entitled to optimize out
the same asm().  In the case of __udelay() in syscounter.c, it calls
`get_ticks()` twice, one for the starting time and the second in the
loop to check the current time.  When compilers inline `get_ticks()`
they see the same `mrrc` instructions and optimize out the second one.
This leads to infinite loop since we don't get updated value from the
system counter.

Here is a portion of the disassembly of __udelay:

  88:	428b      	cmp	r3, r1
  8a:	f8ce 20a4 	str.w	r2, [lr, #164]	; 0xa4
  8e:	bf08      	it	eq
  90:	4282      	cmpeq	r2, r0
  92:	f8ce 30a0 	str.w	r3, [lr, #160]	; 0xa0
  96:	d3f7      	bcc.n	88 <__udelay+0x88>
  98:	e8bd 8cf0 	ldmia.w	sp!, {r4, r5, r6, r7, sl, fp, pc}

Note that final jump / loop at 96 to 88, we don't have any `mrrc`.

With a volatile attribute, the above changes to this:

  8a:	ec53 2f0e 	mrrc	15, 0, r2, r3, cr14
  8e:	42ab      	cmp	r3, r5
  90:	f8c1 20a4 	str.w	r2, [r1, #164]	; 0xa4
  94:	bf08      	it	eq
  96:	42a2      	cmpeq	r2, r4
  98:	f8c1 30a0 	str.w	r3, [r1, #160]	; 0xa0
  9c:	d3f5      	bcc.n	8a <__udelay+0x8a>
  9e:	e8bd 8cf0 	ldmia.w	sp!, {r4, r5, r6, r7, sl, fp, pc}
  a2:	bf00      	nop

I'm advised[1] to put volatile on all asm(), so this commit also adds it
to the asm() in timer_init().

will generate an error if a DCD pointer is present in an image being

d1ceb0c488 imx: mx7: run sec_init for CAAM RNG
This patch adds a sec_init call into arch_misc_init(). Doing so in
conjunction with the patch "drivers/crypto/fsl: assign job-rings to
non-TrustZone" enables use of the CAAM in Linux when OPTEE/TrustZone is
active.

u-boot will initialise the RNG and assign ownership of the job-ring
registers to a non-TrustZone context. With recent changes by Lukas Auer to
fully initialize the RNG in sec_init() this means that u-boot will hand-off
the CAAM in a state that Linux then can use the CAAM without touching the
reserved DECO registers.

This change is safe both for the OPTEE/TrustZone boot path and the regular
non-OPTEE/TrustZone boot path.
