The TI AM43xx HS boards have been using CFG_PRAM to hide the top 64MB
firewalled DRAM memory from U-Boot. However, CFG_PRAM only prevents
U-Boot from relocating into that memory, but it is still open for access
for any other usage.
Therefore, migrate into using CONFIG_SYS_MEM_TOP_HIDE which reduces the
ram size itself ensuring that memory is not visible to U-Boot at all
(either for reloc, or general usage).

Add initial support for Renesas R-Car X5H R8A78000 Ironhide board.
This consists mainly of DTs, Makefile and Kconfig entries and board
specific configuration files.
The DTs will be gradually switched over to Linux DTs via OF_UPSTREAM
once Linux DTs become available upstream, as upstreaming progresses.

Add support for a generic platform which intends to support multiple
boards powered by ARMv8 Samsung Exynos SoCs. Some important features
include:
* Fastboot: This is present to provide an open alternative to Samsung's
proprietary Odin protocol. The board file configures certain features
for fastboot, such as a dynamically allocated fastboot buffer, and
standardized (lowercase) partition aliases.
* EFI: Kernel image can be loaded from an EFI partition. This
adopts a standard booting process, which multiple OS distributions
can rely on.

Mikhail Kshevetskiy <mikhail.kshevetskiy@iopsys.eu> says:
This patch series adds basic support for the boards based on Airoha
EN7523/EN7529/EN7562 SoCs. Due to ATF restrictions these boards are
able to run 32-bit OS only.
This patch series adds support for the following hardware:
* console UART
* ethernet controller/switch
* spinand flash (in non-dma mode)
The following issues may be expected:
* Extra slow UBI attaching in U-Boot (up to 20 sec with fastmap enabled).
This is caused by the lack of DMA support in the U-Boot airoha-snfi driver.
* Linux airoha-snfi driver in some cases might damage you flash data
(see: https://lore.kernel.org/lkml/20251012121707.2296160-15-mikhail.kshevetskiy@iopsys.eu/)
* Latest linux kernel is recommended to properly support flashes
with more than one plane per lun
(see: https://lore.kernel.org/lkml/20251012121707.2296160-7-mikhail.kshevetskiy@iopsys.eu/)
* It's NOT recommended to use flashes working in continuous mode because
U-Boot airoha-snfi driver does not support such flashes properly.
The patches was tested on the board:
- SoC: Airoha EN7562
- RAM: 512 MB
- SPI NAND: 4 Gbit, made by Toshiba
- Linux boot: was NOT tested
The U-Boot was chain-loaded from the running U-Boot. Airoha ATF-2.3 does
not allow easily chain-loading of U-Boot from U-Boot, so a special FIT
image (mimic linux kernel) was created
1) Create u-boot.its file with the following contents:
=== cut here ===
/dts-v1/;

description = "ARM OpenWrt FIT (Flattened Image Tree)";
#address-cells = <1>;

To install new bootloader into the SPI NOR using DFU, it is necessary
to pad the u-boot-with-spl.imx to 0x400 Bytes offset first and then
send it to the board as follows:
"

SPL checks for a magic word in the system manager's scratch
register to determine if an L2 reset has occurred. If detected,
SPL places all slave CPUs (CPU1–3) into WFI mode. The master
CPU (CPU0) then initiates a warm reset by writing to the RMR_EL3
system register and also enters WFI mode.
This warm reset flow is handled entirely within the HPS. The
function `socfpga_sysreset_request()` triggers the warm
reset, and upon SPL re-entry, the updated `lowlevel_init_soc64.S`
handles the necessary initialization.

Make it possible to update E850-96 firmware binaries using EFI Capsule
Update mechanism. For example, to update the U-Boot binary, the capsule
file can be generated like this:
$ ./tools/mkeficapsule --index 4 \
--guid 629578c3-ffb3-4a89-ac0c-611840727779 \
u-boot.bin capsule4.bin
The resulting 'capsule4.bin' should be copied to ESP partition (in
/boot/efi/EFI/UpdateCapsule/ directory). Then after reboot U-Boot will
update the 'bootloader' area in eMMC Boot Partition A (boot0) and remove
the capsule file, by EFI boot manager executed as a part of Standard
Boot:
Applying capsule capsule4.bin succeeded.
Reboot after firmware update.
