The Renesas R9A07G044L (RZ/G2L) SoC includes two Gigabit Ethernet
interfaces which can be supported using the ravb driver. Some RZ/G2L
specific steps need to be taken during initialization due to differences
between this SoC and previously supported SoCs. We also need to ensure
that the module reset is de-asserted after the module clock is enabled
but before any Ethernet register reads/writes take place.

When SPL loading image to secure region, for example, ATF and tee to
DDR secure region. Because the USDHC controller is non-secure master,
it can't access this region and will cause loading issue.
So use a trampoline buffer in non-secure region, then use CPU to copy the

Just like TF-A and OP-TEE, the documentation states a custom path for DM
can be provided at build time by setting TI_DM. This should then set
ti-dm-path which updates ti-dm node filenames in binman.
Two issues prevent this from functioning for most K3 boards. One is when
then DM firmware name is inside a blob-ext node instead of a ti-dm node.
The second is when the filename in the ti-dm node is a pointer to a
blob-ext node. In this case even though the filename is updated, the
filename in the blob-ext is not, so build can fail if the default
file in the blob-ext cannot be found, even if the updated ti-dm file
does exist.
Fix both of these for all K3 by removing any indirect ti-dm nodes and
making sure all DM nodes are labeled with "ti-dm".

Caleb Connolly <caleb.connolly@linaro.org> says:
Introduce a new event to signal that the live tree has been built,
allowing boards to perform fixups on the tree before devices are bound.
Crucially this allows for devices to be enabled or disabled, but also
allows for properties that are parsed during the bind stage to be
modified (such as dr_mode for dwc3).
With this in place, mach-snapdragon is switched over to use the event
and some hacky U-Boot specific DT overrides (which had to be undone
prior to booting an image) are removed in favour of fixing up the
livetree (which is not passed on to further boot stages).
Finally, some minor fixes are made for the QCM2290 RB1 board, the sdcard
is enabled and it now uses USB host mode in U-Boot like it's bigger
sibling the RB2.
Link: https://lore.kernel.org/r/20250411-livetree-fixup-v2-0-1236823377bb@linaro.org
|

The RB1 and RB2 have a single USB controller which is manually muxed
between a type-c port and an internal USB hub via a DIP switch. OTG is
supported in Linux, but the DWC3 driver in U-Boot can only handle a
single mode, and defaults to peripheral mode.
We did hack around this on the RB2, but the RB1 got left out.
Now that we can fix up the live tree before devices are bound, drop the
DTS hacks and do the fixup at runtime instead.

We have improvements to the reliability of H6 and H616 DRAM
initialisation, hopefully avoiding those occasional size misdetections
many people reported before.
Also there is some modernisation of the USB PHY code, to use DT provided
regulators and GPIOs, instead of relying on this being badly duplicated
in Kconfig. This also happens to fix broken USB operations for older
boards (using the A20 SoCs, for instance), which were clashing over
grabbing some GPIOs, leading to a driver bailout. There is also some
rework of the H6/H616 SPL clock code, to prepare it for being reused by
the upcoming Allwinner A523 support. This drops the usage of C structs
to model MMIO register frames, and replaces them by using an addition of
the base address with a macro defined offset. Also in preparation for
A523 there is one fix and one addition for the FEL code, to prepare for
the GICv3 interrupt controller that the new SoC uses. And since this is
a simple fix, and was ready, there is also the watchdog driver for that
new SoC. Finally tossing in an easy fix to some H616 defconfig files to
enable eMMC.
I also use the opportunity to enable proper page table protection
(observing read-only and no-execute attributes), support for which the
arm64 port recently gained. I didn't spot any issues on my arm64 board
tests, but it can be easily disabled or backed out again in case any
issues arise.
Full support for the two new SoC series (A133 and A523) we are working
on is not quite ready yet, but might follow still a bit later if
progress permits.
CI passed, and boot-tested on at least one board with a H616, H6, A64,
H3, A20, T113s.

U-Boot drivers often revert to using C structures for modelling hardware
register frames. This creates some problems:
- A "struct" is a C language construct to group several variables
together. The details of the layout of this struct are partly subject
to the compiler's discretion (padding and alignment).
- The "packed" attribute would force a certain layout, but we are not
using it.
- The actual source of information from the data sheet is the register
offset. Here we create an artificial struct, carefully tuning the
layout (with a lot of reserved members) to match that offset. To help
with correctness, we put the desired information as a *comment*,
though this is purely for the human reader, and has no effect on the
generated layout. This sounds all very backwards.
- Using a struct suggests we can assign a pointer and then access the
register content via the members. But this is not the case, instead
every MMIO register access must go through specific accessor functions,
to meet the ordering and access size guarantees the hardware requires.
- We share those structs in code shared across multiple SoC families,
though most SoCs define their own version of the struct. Members must
match in their name, across every SoC, otherwise compilation will fail.
We work around this with even more #ifdefs in the shared code.
- Some SoCs have an *almost* identical layout, but differ in a few
registers. This requires hard to maintain #ifdef's in the struct
definition.
- Some of the register frames are huge: the H6 CCU device defines 127
registers. We use 15 of them. Still the whole frame would need to be
described, which is very tedious, but for no reason.
- Adding a new SoC often forces people to decide whether to share an
existing struct, or to create a new copy. For some cases (say like 80%
similarity) this works out badly either way.
The Linux kernel heavily frowns upon those register structs, and instead
uses a much simpler solution: #define REG_NAME <offset>
This easily maps to the actual information from the data sheet, and can
much simpler be shared across multiple SoCs, as it allows to have all
SoC versions visible, so we can use C "if" statements instead of #ifdef's.
Also it requires to just define the registers we need, and we can use
alternative locations for some registers much more easily.
Drop the usage of "struct sunxi_prcm_reg" in the H6 SPL clock code, by
defining the respective register names and their offsets, then adding
them to the base pointer.
We cannot drop the struct definition quite yet, as it's also used in

Thanks for Jernej's JTAG debugging effort, it turns out that the BROM
expects SP_IRQ to be saved and restored, when we want to enter back into
FEL after the SPL's AArch64 stint.
Save and restore SP_IRQ as part of the FEL state handling. The banked
MRS/MSR access to SP_IRQ, without actually being in IRQ mode, was
introduced with the ARMv7 virtualisation extensions. The Arm Cortex-A8
cores used in the A10/A13s or older F1C100s SoCs would not support that,
but this code here is purely in the ARMv8/AArch64 code path, so it's
safe to use unconditionally.

To be able to return to the BootROM FEL USB debug code, we must restore
the core's state as accurately as possible after the SPL has been run.
Since the BootROM runs in AArch32, but the SPL uses AArch64, this requires
a core reset, which clears the core's state.
So far we were saving and restoring the required registers like SCTLR
and VBAR, but could ignore the interrupt controller's state (GICC), since
that lives in MMIO registers, unaffected by a core reset.
Newer Allwinner SoCs now feature a GICv3 interrupt controller, which keeps
some GIC state in architected system registers, and those are cleared
when we switch back to AArch32.
To enable FEL operation on the Allwinner A523 SoC,
Add AArch32 assembly code to save and restore the ICC_PMR and ICC_IGRPEN1
system registers. The other GICv3 sysregs are either not relevant for the
BROM operation, or haven't been changed from their reset defaults by the
BROM anyway.
This enables FEL operation on the Allwinner A523 family of SoCs.
