eb1e370a9b thermal: imx_tmu: Move architecture code into driver
Stop polluting the architecture directory with driver specific code,
move it into driver where it should be. Split the code slightly so
the MX8MM/MX8MN fuse readout and programming and MX8MP fuse readout
and programming are in their separate functions, and called in case
of matching SoC.

b1d20ae5a6 ARM: imx: Fix parsing of ROM log event IDs on iMX8M
It seems like the ROM log events for the iMX8M are not fully covered by
AN12853 i.MX ROMs Log Events, Rev. 0, May 2020. On iMX8M the ROM event
ID 0x82 seems to use parameter0 which stops the parsing because the end
of list is detected too early.

This patch adds ROM event ID 0x82 and skips the next word if ID 0x82 is
parsed.

feb710b381 arm: imx8m: remove unused and obsolete board_fix_fdt() in SOC context
It doesn't seem appropriate for arch/SOC to use a board-level
functionality (CONFIG_OF_BOARD_FIXUP), because this prevents boards
that need to do FDT fixup from using that feature.

Also, this code is completely dead and useless (from comments by
Rasmus Villemoes on the mailing list):

  - No in-tree imx8m-based board seems to set CONFIG_OF_BOARD_FIXUP
  - The nodes which that function wants to disable don't even exist in
    the U-Boot copy of imx8mp.dtsi.

This code was introduced in commit 35bb60787b. It seems to be some
random import of code from downstream NXP U-Boot, with a commit
message that makes no sense in upstream context.

a5ee05cf71 ARM: imx: Pick correct eMMC boot partition from ROM log
In case the iMX8M boot from eMMC boot partition and the primary image
is corrupted, the BootROM is capable of starting a secondary image in
the other eMMC boot partition as a fallback.

However, the BootROM leaves the eMMC BOOT_PARTITION_ENABLE setting as
it was, i.e. pointing to the boot partition containing the corrupted
image, and the BootROM does not provide any indication that this sort
of fallback occured.

According to AN12853 i.MX ROMs Log Events, Rev. 0, May 2020, it is
possible to determine whether fallback event occurred by parsing the
ROM event log. In case ROM event ID 0x51 is present, fallback event
did occur.

This patch implements ROM event log parsing and search for event ID
0x51 for all iMX8M SoCs, and based on that corrects the eMMC boot
partition selection. This way, the SPL loads the remaining boot
components from the same eMMC boot partition from which it was
started, even in case of the fallback.

errors are very difficult to overcome.

Richard Biener says [1]:
  Note that global register vars shouldn't be used with LTO and if they
  are restricted to just a few compilation units the recommended fix is
  to build those CUs without -flto.

We cannot do this for U-Boot since all CUs use -ffixed-reg flag.

It seems that with LTO we could in fact store the gd pointer differently
and gain performance or size benefit by allowing the compiler to use
r9 / x18. But this would need more work.

So for now, when building with LTO, go the clang way, and instead of
declaring gd a global register variable, we make it a function call via
macro.

ea2b26fb12 iMX8MQ: Recognize the B2 revision
i.MX8MQ B2 is using same value in OCOTP_READ_FUSE_DATA like B1, so
we have to check the ROM verision to distinguish the revision.

As we have checked the B1 rev for sticky bits work around in
secure boot. So it won't apply on B2.

35b65dd8ef reset: Remove addr parameter from reset_cpu()
Historically, the reset_cpu() function had an `addr` parameter which was
meant to pass in an address of the reset vector location, where the CPU
should reset to.  This feature is no longer used anywhere in U-Boot as
all reset_cpu() implementations now ignore the passed value.  Generic
code has been added which always calls reset_cpu() with `0` which means
this feature can no longer be used easily anyway.

Over time, many implementations seem to have "misunderstood" the
existence of this parameter as a way to customize/parameterize the reset
(e.g.  COLD vs WARM resets).  As this is not properly supported, the
code will almost always not do what it is intended to (because all
call-sites just call reset_cpu() with 0).

To avoid confusion and to clean up the codebase from unused left-overs
of the past, remove the `addr` parameter entirely.  Code which intends
to support different kinds of resets should be rewritten as a sysreset
driver instead.

This transformation was done with the following coccinelle patch:

    @@
    expression argvalue;
    @@
    - reset_cpu(argvalue)
    + reset_cpu()

    @@
    identifier argname;
    type argtype;
    @@
    - reset_cpu(argtype argname)
    + reset_cpu(void)
    { ... }
