73e88a9010 board: Move beagleplay under beagle vendor folder
Move beagleplay support away from ti/am62x to it's own beagle vendor
folder.

This forms the starting point for new beagle platforms added under it's
own board vendor folder.

As part of this create all the associated files with a bare minimum
beagleplay.c file.

c36377d09e arm: mach-k3: j721e: Improve support for UDA FS
Commit 5019170970 ("arch: arm: mach-k3: j721e: add support for UDA
FS") introduced basic UDA FS support, however, we can Take approach
similar to commit 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.

Currently each set of board targets from a vendor is selected inside

For instance you can select both TARGET_AM654_A53_EVM and

5fecea171d treewide: use dev_read_addr_*_ptr() where appropriate
A follow-up to commit 842fb5de42
("drivers: use devfdt_get_addr_size_index_ptr when cast to pointer")
and commit 320a1938b6
("drivers: use devfdt_get_addr_index_ptr when cast to pointer").

In addition to using the *_ptr variants of these functions where the
address is cast to a pointer, this also changes devfdt_get_addr_*() to
dev_read_addr_*() in a few places. Some variable and field types are
changed from fdt_addr_t or phys_addr_t to void* where the cast was
happening later.

This patch fixes a number of compile warnings when building a 32bit
U-Boot with CONFIG_PHYS_64BIT=y. In some places, it also fixes error
handling where the return value of dev_read_addr() etc. was checked for
NULL instead of FDT_ADDR_T_NONE.

When setting boot media to load the TIFS binary in legacy boot flow

dm_timer_init() to grab the tick-timer, which is mcu_timer0. Since we

6ab77bb14f Convert CFG_SYS_UBOOT_START to Kconfig
Commit 65cc0e2a65 ("global: Move remaining CONFIG_SYS_* to CFG_SYS_*")
renamed CONFIG_SYS_UBOOT_START to CFG_SYS_UBOOT_START. Unfortunately,
this meant that the value was no longer available to the Makefile. This
caused imxrt to fail to boot. All the other boards that used this
variable were unaffected because they were using the default value
which is CONFIG_TEXT_BASE.

This commit converts CFG_SYS_UBOOT_START to Kconfig and sets the default
value to CONFIG_TEXT_BASE.

dd5d1c5dcc arch: arm: mach-k3: common: Return a pointer after setting page table
In spl_dcache_enable after setting up page table, set gd->relocaddr
pointer to tlb_addr, to get next location to reserve memory. Align
tlb_addr with 64KB address.

efda93c6b5 arm: mach-k3: am62a7: change some prints to debug prints
There is little need to print the devstat information or when we exit a
function during a typical boot. Remove them to reduce the noise during
typical operation

70aa5a94d4 arm: mach-k3: am62: Fixup CPU core, gpu and pru nodes in fdt
AM62x SoC is available in multiple variant:
- CPU cores (Cortex-A) AM62x1 (1 core), AM62x2 (2 cores), AM62x4 (4 cores)
- GPU AM625x with GPU, AM623x without GPU
- PRU (Programmable RT unit) can be present or not on AM62x2/AM62x4

Remove the relevant FDT nodes by reading the actual configuration
from the SoC registers, with that change is possible to have a single
dts/dtb file handling the different variant at runtime.
While removing GPU node and CPU nodes also the watchdog node
in the same Module Domain is removed.

A similar approach is implemented for example on i.MX8 and STM32MP1 SoC.

7b7288df34 arm: k3: Fix ft_system_setup so it can be enabled on any SoC
ft_system_setup cannot be enabled on SoC without msmc sram otherwise
fdt_fixup_msmc_ram function fails causing system reset.

Fix by moving fdt_fixup_msmc_ram to common_fdt.c file and creating
SoC (AM654, J721E and J721S2) specific files for fdt fixups.

This change was verified to not change anything on any existing board
(all the J721S2, AM654 and J721E boards requires it,
none of the remaining k3 boards require it).

is present in above 64bit region. Open this up in bootloader to allow
Linux to access OSPI flashes in mmap mode.

Without this kernel will crash when accessing this region due to
