arm64: renesas: Make R-Car board code 32-bit ARMv8-M compatible

2026-04-08T17:35:05+00:00

The 64-bit R-Car board code is currently unbuildable on 32-bit ARM
cores. Skip DRAM initialization bits to make the code compatible with
these cores, because those cores do not use the DRAM, they only use
SRAM.

arm: renesas: Use stock lowlevel_init function and remove s_init

2026-04-08T17:35:05+00:00

Replace s_init() early initialization at the end of lowlevel_init
by invoking the same code in mach_cpu_init(). The mach_cpu_init()
is called a bit later, but as the code initializes timer and no
code uses timer until mach_cpu_init(), this does not pose a problem.

treewide: Clean up DECLARE_GLOBAL_DATA_PTR usage

2026-02-17T19:50:22+00:00

Remove DECLARE_GLOBAL_DATA_PTR from files where gd is not used, and
drop the unnecessary inclusion of asm/global_data.h.

Headers should be included directly by the files that need them,
rather than indirectly via global_data.h.

renesas: common: Include asm-generic/u-boot.h

2026-02-17T19:50:22+00:00

struct bd_info is defined in asm-generic/u-boot.h. Include it to avoid
building error after asm/global_data.h are removed from this file.

arm64: dts: renesas: Add Renesas R-Car X5H R8A78000 Ironhide board code

2025-12-02T23:17:15+00:00

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.

arm64: renesas: Add Renesas R-Car Gen5 infrastructure

2025-12-02T23:17:15+00:00

Add initial changes to support Renesas R-Car Gen5 SoC.

Introduce Kconfig entries, architecture headers and PRR IDs for Renesas
R-Car Gen5 and R-Car X5H R8A78000 SoC. Add Makefile change to produce
u-boot-elf.srec with correct offset for installation tooling. Update
MAINTAINERS entry to cover both r8a77nnn and r8a78nnn .

spl: split spl_board_fixups to arch/board specific

2025-10-22T18:05:52+00:00

The current spl_board_fixups API allows for modification of spl_image
before the SPL jumps to it. This can be used to modify the DT for the
next boot stage, however the current API only allows either the machine
arch or the board to use it.

This limits the utility of the API as there might be certain fixups that
should be applied to all boards sharing the same machine architecture
with others being board specific.

For TI's K3 specifically, this prevents us from performing architecture
level fixups since a lot of TI boards are already making use of the
spl_board_fixups API.

Therefore this patch splits the API into two to allow both board and the
architecture specific fixups. The order is kept as arch then board to
give board specific fixups the precedence.

arm64: renesas: r8a779g3: Reset PCIe before next stage on Retronix R-Car V4H Sparrow Hawk

2025-10-17T19:53:52+00:00

Fully reset both PCIe controllers before booting the next stage on
Retronix R-Car V4H Sparrow Hawk board. This is necessary especially
in case U-Boot brought up the PCIe controllers, at which point the
next stage might be confused by the state of the PCIe controller.
The reset has to happen this late and not in the PCIe controller
driver, because the SRCR11 bits seem to affect both controllers.

board: rzg2l: Check the DTB pointer passed by the TF-A.

2025-09-25T21:18:34+00:00

On the RZG2L platform, the advised
TF-A (https://github.com/renesas-rz/rzg_trusted-firmware-a/tree/v2.5/rzg2l)
does not pass any DTB blob to U-Boot.

On the other hand, the RZG2L part of U-Boot expects a DTB to be passed.  It
means that if one flashes the latest TF-A as well as the mainline U-Boot,
it will crash trying to dereference the NULL DTB pointer before outputing
anything.

Check if the DTB pointer is NULL before trying to use it.
