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.

7842b6a91e arm: move SYS_ARCH_TIMER to KConfig
SYS_ARCH_TIMER guards the usage of the ARM Generic Timer (aka arch
timer) in U-Boot.
At the moment it is mandatory for ARMv8 and used by a few ARMv7 boards.
Add a proper Kconfig symbol to express this dependency properly,
allowing certain board configuration to later disable arch timer in case
there are any problems with it.

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: rtc core: registered

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 0x00000020 from SNVS_LPCR @ 0x00000038
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.

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.

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().

For proper authentication the HAB code must check if the CSF is valid.
Users must call the csf_is_valid() function to parse the CSF prior to
authenticating any additional images. The function will return a failure
if any of the following invalid conditions are met:

- CSF pointer is NULL
- CSF Header does not exist
- CSF does not lie within the image bounds
- CSF command length zero

8c4037a09a imx: hab: Ensure the IVT DCD pointer is Null prior to calling HAB authenticate function.
DCD commands should only be present in the initial boot image loaded by
the SoC ROM. DCD should not be present in images that will be verified
by software using HAB RVT authentication APIs. Newer versions of HAB
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.

It is highly recommended this check is in place to ensure additional HAB
verified images do not include a DCD table.

669f2d189e imx: hab: Keep CAAM clock enabled after authenticating additional images
Currently it is not possible to run CMD_DEK on i.MX SPL targets:

=> dek_blob 0x12000000 0x12001000 128

The system hangs after running dek_blob because the CAAM clock is being
disabled by the HAB code. There is no need to disable CAAM clock after
authenticating additional boot images, thus keep CAAM clock enabled to
address this issue.

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.

the i.MX7. Code based on new BootROM callbacks will just have HAB_SUCCESS
as a result code. Adding support for the new BootROM callbacks is a TODO.

c5800b2541 arm: imx: hab: Fix authenticate_image input parameters
u-boot command "hab_auth_img" tells a user that it takes

- addr - image hex address
- offset - hex offset of IVT in the image

but in fact the callback hab_auth_img makes to authenticate_image treats
the second 'offset' parameter as an image length.

Furthermore existing code requires the IVT header to be appended to the end
of the image which is not actually a requirement of HABv4.

This patch fixes this situation by

1: Adding a new parameter to hab_auth_img
   - addr   : image hex address
   - length : total length of the image
   - offset : offset of IVT from addr

2: Updates the existing call into authenticate_image() in
   arch/arm/mach-imx/spl.c:jump_to_image_no_args() to pass
   addr, length and IVT offset respectively.

This allows then hab_auth_img to actually operate the way it was specified
in the help text and should still allow existing code to work.

It has the added advantage that the IVT header doesn't have to be appended
to an image given to HAB - it can be prepended for example.

Note prepending the IVT is what u-boot will do when making an IVT for the
BootROM. It should be possible for u-boot properly authenticate images
made by mkimage via HAB.

This patch is the first step in making that happen subsequent patches will
focus on removing hard-coded offsets to the IVT, which again is not
mandated to live at the end of a .imx image.

9535b3975f arm: imx: hab: Fix authenticate_image result code
authenticate_image returns 1 for success and 0 for failure. That result
code is mapped directly to the result code for the command line function
hab_auth_img - which means when hab_auth_img succeeds it is returning
CMD_RET_FAILURE (1) instead of CMD_RET_SUCCESS (0).

This patch fixes this behaviour by making authenticate_image() return 0 for
success and 1 for failure. Both users of authenticate_image() as a result
have some minimal churn. The upshot is once done when hab_auth_img is
called from the command line we set $? in the standard way for scripting
functions to act on.

adbb051f08 arm: imx: hab: Make authenticate_image return int
Both usages of authenticate_image treat the result code as a simple binary.
The command line usage of authenticate_image directly returns the result
code of authenticate_image as a success/failure code.

Right now when calling hab_auth_img and test the result code in a shell a
passing hab_auth_img will appear to the shell as a fail.

The first step in fixing this behaviour is to fix-up the result code return
by authenticate_image() itself, subsequent patches fix the interpretation
of authenticate_image so that zero will return CMD_RET_SUCCESS and non-zero
will return CMD_RET_FAILURE.

The first step is fixing the return type in authenticate_image() so do that
now.

dbeaa1d131 ARM: imx: cm_fx6: export board and soc info to env
Like many other i.MX6 based boards, there are multiple variants of
the cm-fx6 module featuring different SoC variants. Furthermore, the
module can be paired with multiple baseboards.

At the same time modern distribution like Fedora require U-Boot to
select a proper devicetree which depends on the SoC variant and the
baseboard.

Thus, export the SoC variant and the actual board to the environment
following the conventions of other i.MX6 devices (e.g. the NXP boards)
such that the environment can select a devicetree file to load.

For now, we only know for sure that the cm-fx6 module and the SB-fx6m
baseboard amount to a Utilite Computer variant (depending on the SoC).
Further combinations may be added in the future; e.g. CompuLab's
evaluation board once someone can verify the identification string
stored in its eeprom.

commit 20f1471416 ("imx: spl: Update NAND bootmode detection bit")
broke the NAND bootmode detection by checking if
BOOT_CFG1[7:4] == 0x8 for NAND boot mode.
This commit essentially reverts it, while using the IMX6_BMODE_*
macros that were introduced since.

Tables 8-7 & 8-10 from IMX6DQRM say the NAND boot mode selection
is done when BOOT_CFG1[7] is 1, but BOOT_CFG1[6:4] is not
necessarily 0x0 in this case.
Actually, NAND boot mode is when 0x8 <= BOOT_CFG1[7:4] <= 0xf,
like it was in the code before.

It generates an SPL image that can be loaded using imx_usb or
SB_LOADER.exe.

When run, it will generate a set of calibration constants for
use in either or both a DCD configuration file for boards that
use u-boot.imx or struct mx6_mmdc_calibration for boards that
boot via SPL.

In essence, it is a configurable, open-source variant of the
Freescale ddr-stress tool.

correct dtb is imx6sx-sdb-reva.dtb, so make this possible.

While at it, remove an extra 'mmc dev'.

4555c26142 imx: Add a common way for detecting NXP boards revision
NXP development boards based on i.MX6/i.MX7 contain the board
revision information stored in the fuses.

Introduce a common function that can be shared by different boards and
convert mx6sabreauto to use this new mechanism.

e2162d709f imx: Remove boolean parameter from wdog powerdown function
imx_set_wdog_powerdown() is always used to disable the power down
enable bit, so remove the boolean parameter of the function.

It is also a bit strange to write a boolean value into registers,
so this new version makes explicit that we are writing 0.

While at it, rename it to imx_wdog_disable_powerdown().
