[PATCH V4 0/7] Migrate IMX8, IMX8M and IMX9 to use imx8_cpu

[PATCH V4 0/7] Migrate IMX8, IMX8M and IMX9 to use imx8_cpu

[Adam Ford]

The imx8_cpu driver uses the driver model to represent the processor
cores in the dm tree as well as display the processor type and speed
on boot.  Currently, the imx8_cpu driver only displays the temperature
grade of the processor if the processor is IMX9, so in order to display
that info, the check in imx8_cpu is changed to check for IMX_TMU
and IMX_TMU is implied for IMX8, IMX8M and IMX9 SoC familes.  If
users want to fall back to the older method to display the SoC type
or remove the temperature grade information, they can.  Doing this
at the SoC family level reduces the number of duplicated config options
for each board, and was done at the request of the IMX U-Boot custodian.

V4:  Make IMX9 select CPU_IMX instead of imply since it appears to be
     required for all in the platform.
     Fixed some whitespace in imx8_cpu around the temperature grade message.
     Re-ordered some items in Kconfig to keep them alphabetical
     Added more CPU items to the list inside imx8_cpu to match what was done
     from arch/arm/mach-imx/cpu.c.
     
V3:  Added the imply IMX_TMU for the 8M family and added the imply for
     CPU and CPU_IMX to IMX8, IMX8M and IMX9 families.  CPU_IMX depends
     on CPU, so both have to be selected.

V2:  Changed the check in imx8_cpu to drop the IMX9 check and instead
     imply IMX_TMU in the IMX9 family

[PATCH V4 1/7] imx: imx9: Imply IMX_TMU

[Adam Ford]

If the CPU Information is displayed from imx8_cpu, it displays
the cpu temperature grade and operating temperature if
CONFIG_IMX9 is defined. This behavior is similar to what
happens arch/arm/mach-imx/cpu.c except that the latter
checks for CONFIG_IMX_THERMAL or CONFIG_IMX_TMU.
In preparation to make imx8_cpu act like the previous
implementation for any CPU, make IMX9 imply IMX_TMU, so
it will be always displayed unless a user decides to
disable it.

[PATCH V4 2/7] cpu: imx8_cpu: Expand get_imx_type_str list of supported CPUs

[Adam Ford]

The imx8_cpu is capable of running on IMX8, IMX8M, and IMX9
families, but the CPU list is limited on the 8M variants.  Expand
this list to show more variants and their respective names.

If the CPU Information is displayed from imx8_cpu, it displays the
cpu temperature grade and operating temperature if CONFIG_IMX9 is
defined. This behavior is similar to what happens mach-imx/cpu.c,
except that the latter checks for IMX_THERMAL or IMX_TMU.

for any CPU, make IMX8M imply IMX_TMU so it will be always displayed
unless a user decides to disable it.

[PATCH V4 4/7] cpu: imx8_cpu: Print Speed grade if IMX_TMU.

[Adam Ford]

Much of the data that is display by imx8_cpu.c is also displayed from
arch/arm/mach-imx/cpu.c, except the temperature grade and active
temperature are only displayed when SoC is an i.MX9. Since IMX9 now
implies IMX_TMU, change this to check for IMX_TMU in the same way
it's done in mach-imx/cpu.c to enable displaying this information
for any SoC with either of this config enabled.
Since additional text may appear due to this commit, remove
the extra space in the message displaying the temperature
grade.

Sorry about that...again.  Thanks.

Once this is complete, I'll have a smaller patch series which shrinks
my 8MP SPL code by around 4k by #ifdef'ing out dead code.  Hopefully
it's not too cluttered, but that smaller series depends on both the
UART clock and the CPU_IMX updates.

Don't thank me yet.  It's going to increase the ifdef-ery, and it gets
a bit ugly.  I'm tempted to throw in some To-Do's, because I can see
some more improvement possibilities as I dig into some of this code,
but I am not prepared to touch them yet.

Well, I am not sure if it's good news or bad, but after rebasing my
changes on top of U-Boot-Next,  the SPL size delta goes away, so I am
not sure if I even have anything to push, since it makes no difference
anymore.  :-(  Part of me wants to bisect it to see what made the
difference.
