cb4e79b7ba imx8m: soc.c: demote some printfs to debug
Getting

  Found /vpu_g1@38300000 node
  Modify /vpu_g1@38300000:status disabled
  Found /vpu_g2@38310000 node
  Modify /vpu_g2@38310000:status disabled

etc. on the console on every boot is needlessly verbose. Demote the
"Found ..." lines to debug(), which is consistent with other instances
in soc.c.

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.

The DWMAC clock in i.MX8M Plus were so far configured via ad-hoc
architecture code. Replace that with DM clock instead. This way,
the driver claims all its required clock, enables and disables
them, and even gets the CSR clock rate and sets the TX clock rate,
without any need of architecture specific register fiddling. Drop
the architecture specific code while at it too.

The adjustment here is modeled after STM32MP15xx clock handling

This is because the weak empty array of structures "hostmap" is eventually

Fix this by avoiding weak variable size array, instead use a weak function
which returns single pointer to the array.

74f88b7221 ARM: imx: imx8m: Fix board_get_usable_ram_top()
The 4 GiB boundary is at 0xffffffff+1 , not at 0x80000000, fix this.

The PHYS_SDRAM of i.MX8M is at 0x40000000 , so to restrict ram_top
below 4 GiB, the ram_top has to be set to 0xffffffff as it is not
an offset from the start of PHYS_SDRAM, but rather a physical address
marking the topmost allowed DRAM address.

Fixes: e27bddff4b ("imx8m: Restrict usable memory to space below 4G boundary")

2395625209 board: gateworks: venice: add imx8mp-venice-gw740x support
The GW74xx is based on the i.MX 8M Plus SoC featuring:
 - LPDDR4 DRAM
 - eMMC FLASH
 - Gateworks System Controller
 - PCIe Gen 3.0 switch (build option)
 - USB 3.0 HUB
 - USB Type-C front panel connector
 - GPS
 - 3-axis accelerometer
 - CAN bus
 - 6x GbE RJ45 front-panel jacks
  - 1x IMX8M FEC RGMII GbE (with Passive PoE)
  - 5x IMX8M EQOS RGMII 6 port GbE Switch
    (1x with 802.3af class 5 Active PoE)
 - RS232/RS485/RS422 serial transceiver
 - MIPI header (DSI/CSI/GPIO/PWM/I2S)
 - DigI/O header (UART/GPIO/I2C/ADC)
 - 802.11ac WiFi
 - Bluetooth BLE
 - 3x MiniPCIe sockets with PCI/USB
 - 1x M.2 Socket with USB2.0, PCIe, and dual-SIM
 - PMIC
 - Wide range DC input supply (8V to 60V DC)

Do the following to add support for this and future imx8mp-venice boards:
 - add dts
 - add DRAM config
 - add PMIC config
 - add IMX8MP support in spl.c and venice.c

fb9ec33878 board: gateworks: venice: use common GSC driver
Use the common GSC driver.

This allows us to do some additional cleanup:
 - rename gsc{.c,.h} to eeprom{.c.h} for clarity
 - collapse eeprom_get_dev
 - remove unnecessary header files and alphabatize includes

cb61b2fb2b ARM: imx: Get rid of only i.MX8M SMCCC arch call
This is the only place where i.MX8M code does SMCCC call, remove it.
The output has little value as it prints some part of commit ID, and
worse, if there is no SMC handler installed, the code outright hangs
or crashes the system.

By removing this one instance of SMCCC call, U-Boot no longer depends
on SMC handlers and can boot without hanging in any case. If there is
a need to dump this commit ID, use CMD_SMC instead and do 'smc' call
from U-Boot shell or scripts instead of hard-coding SMCCC dependency
into architecture code. This particular code can be replaced by:
 => smc 0xc2000003 0 0 0 0 0 0
