0f1c1e8b36 arm: mach-k3: am625: Add support for UDA FS
While boot partition support with EMMC boot is useful, it is
constrained by the size of boot hardware partition itself.

In the case of K3 devices, tispl images can contain OP-TEE images that
can substantially vary in size and the u-boot image itself can vary over
time as we enable various features.

So use the CSD information in the case of EMMC_BOOT configuration being
enabled to pick boot partition or UDA FS mode operation to pick.

If EMMC_BOOT is disabled, then depend on filesystem configuration to
pick data from UDA.

While at this, drop the extraneous whitespace.

8b5c4cd78d arm: mach-k3: am625_init: Convert rtc_erratumi2327_init to static
The erratum is called locally, make it static, drop the #ifdeffery since
it will only be called in R5 build and mark it potentially unused to
stop compiler screaming at us.

While at this, drop the redundant return for a void function.

12fdacea5a board: ti: am62x: evm: Update function calls for splash screen
Use spl_dcache_enable, in place of setup_dram, arch_reserve_mmu to set
up pagetable, initialise DRAM and enable Dcache to avoid multiple
function calls.

Check for CONFIG_SPL_VIDEO in place of CONFIG_SPL_VIDEO_TIDSS to prevent
any build failure in case video config is not defined and video related
functions are called.

Check for CONFIG_SPL_SPLASH_SCREEN and CONFIG_SPL_BMP before calling
splash_display to avoid compilation failure.

fb3474bef0 arm: mach-k3: am625_init: Add Erratum WA for RTC startup
In the first silicon revision of the am62x family of SoCs, the hardware
wakeup event cannot be used if software is unable to unlock the RTC
device within one second after boot. To work around this limitation
unlock RTC as soon as possible in the boot flow to maximize our chance
of linux being able to use this device.

Add the erratum i2327 workaround to initialize the RTC.

f5e4944608 arm: mach-k3: Move sysfw-loader.h out of mach includes
This header is only used locally by K3 init files, no need to have it
up with the global mach includes. Move into local includes.

7c34b71a42 arm64:mach-k3 am625_init: Correct boot mode detection
The boot mode detection assumes that BOOT_DEVICE_MMC2 should always
result in MMCSD_MODE_FS, but MMCSD_MODE_RAW is also a valid option for
this port.

The current logic also avoids looking at the bootmode pin strapping,
which should be the primary means of determining whether a device is
being booted in MMCSD_MODE_EMMCBOOT mode.

Switch around the logic to check the boot mode to determine whether the
eMMC boot mode is expected or MMC/SD boot mode. From there we can look
at the boot mode config if in MMC/SD boot mode to determine whether to
attempt RAW or FS based booting.

This change allows U-Boot to also be successfully booted from RAW
offsets in addition to from a filesystem.

169582025a arm64: mach-k3: am625_init: Probe ESM nodes
On AM62x devices, main ESM error event outputs can be routed to
MCU ESM as inputs. So, two ESM device nodes are expected in the
device tree : one for main ESM and another one for MCU ESM.
MCU ESM error output can trigger the reset logic to reset
the device when CTRLMMR_MCU_RST_CTRL:MCU_ESM_ERROR_RESET_EN_Z is
set to '0'.

architecture platform, providing ultra-low-power modes, dual display,
multi-sensor edge compute, security and other BOM-saving integration.
The AM62 SoC targets broad market to enable applications such as
Industrial HMI, PLC/CNC/Robot control, Medical Equipment, Building
Automation, Appliances and more.

  in 3D graphic display case and Android.
* PRU(Programmable Realtime Unit) support for customized programmable
  interfaces/IOs.
* Integrated Giga-bit Ethernet switch supporting up to a total of two
  external ports (TSN capable).
