The configuration CONFIG_OPTEE is defined 2 times:
1- in lib/optee/Kconfig for support of OPTEE images loaded by bootm command
2- in drivers/tee/optee/Kconfig for support of OP-TEE driver.
It is abnormal to have the same CONFIG define for 2 purpose;
and it is difficult to managed correctly their dependencies.
Moreover CONFIG_SPL_OPTEE is defined in common/spl/Kconfig
to manage OPTEE image load in SPL.
This definition causes an issue with the macro CONFIG_IS_ENABLED(OPTEE)
to test the availability of the OP-TEE driver.
This patch cleans the configuration dependency with:
- CONFIG_OPTEE_IMAGE (renamed) => support of OP-TEE image in U-Boot
- CONFIG_SPL_OPTEE_IMAGE (renamed) => support of OP-TEE image in SPL
- CONFIG_OPTEE (same) => support of OP-TEE driver in U-Boot
- CONFIG_OPTEE_LIB (new) => support of OP-TEE library
After this patch, the macro have the correct behavior:
- CONFIG_IS_ENABLED(OPTEE_IMAGE) => Load of OP-TEE image is supported
- CONFIG_IS_ENABLED(OPTEE) => OP-TEE driver is supported

During the migration to a single DTSI for the CP110-s specific pinctrl
compatibles were moved to the SoC DTSI as CP0 and CP1 have some specifics.
Namely, CP0 eMMC/SDIO support depends on the mvebu-pinctrl driver setting
the BIT(0) in eMMC PHY IO Control 0 Register to 0 in order for the connect
the eMMC/SDIO PHY to the controller and not use it as a MPP pin multiplexor.
So, the mvebu-pinctrl driver check specifically for the
"marvell,armada-8k-cpm-pinctrl" compatible to clear the that bit.
Issue is that compatibles in the 8040 DTSI were set to "marvell,8k-cpm-pinctrl"
for CP0 and "marvell,8k-cps-pinctrl" for the CP1.
This is obviously incorrect as the pinctrl driver does not know about these.
So fix the regression by applying correct compatibles to the DTSI.

Commit 0d52bab46 (mx7dsabre: Enable DM_ETH) changed these flags from 0
(aka GPIO_ACTIVE_HIGH) to GPIO_ACTIVE_LOW. It claimed to "Also sync
device tree with v5.5-rc1", but in the linux tree, these gpios have
always been GPIO_ACTIVE_HIGH ever since this node was introduced
around v4.13 (linux commit 184f39b5).
I'm guessing that the reason for the GPIO_ACTIVE_LOW was to work
around the behaviour of the soft-spi driver back then, which
effectively defaulted to spi-mode 3 and not 0. That was arguably a bug
in the soft-spi driver, which then got fixed in 0e146993bb (spi: add
support for all spi modes with soft spi), but that commit then broke
ethernet on this board.
Fix it by setting the gpios as active high, which as a bonus actually
brings us in sync with the .dts in the linux source tree.
Without this, one gets
Net: Could not get PHY for FEC0: addr 0
No ethernet found.
With this, ethernet (at least ping and tftp) works as expected from

strncpy() simply bails out when copying a source string whose size
exceeds the destination string size, potentially leaving the destination
string unterminated.
One possible way to address is to pass MDIO_NAME_LEN - 1 and a
previously zero-initialized destination string, but this is more
difficult to maintain.
The chosen alternative is to use strlcpy(), which properly limits the
copy len in the (srclen >= size) case to "size - 1", and which is also
more efficient than the strncpy() byte-by-byte implementation by using
memcpy. The destination string returned by strlcpy() is always NULL

it became apparent that nobody really knows what "SGMII 2500" is.
Certainly, Freescale/NXP hardware engineers name this protocol
"SGMII 2500" in the reference manuals, but the PCS devices do not
support any "SGMII" specific features when operating at the speed of
2500 Mbps, no in-band autoneg and no speed change via symbol replication
. So that leaves a fixed speed of 2500 Mbps using a coding of 8b/10b
with a SERDES lane frequency of 3.125 GHz. In fact, "SGMII 2500 without
in-band autoneg and at a fixed speed" is indistinguishable from
"2500base-x without in-band autoneg", which is precisely what these NXP
devices support.
So it just appears that "SGMII 2500" is an unclear name with no clear
definition that stuck.
As such, in the Linux kernel, the drivers which use this SERDES protocol
use the 2500base-x phy-mode.
This patch converts U-Boot to use 2500base-x too, or at least, as much
as it can.
Note that I would have really liked to delete PHY_INTERFACE_MODE_SGMII_2500
completely, but the mvpp2 driver seems to even distinguish between SGMII
2500 and 2500base-X. Namely, it enables in-band autoneg for one but not
the other, and forces flow control for one but not the other. This goes
back to the idea that maybe 2500base-X is a fiber protocol and SGMII-2500
is an MII protocol (connects a MAC to a PHY such as Aquantia), but the
two are practically indistinguishable through everything except use case.
NXP devices can support both use cases through an identical configuration,
for example RX flow control can be unconditionally enabled in order to
support rate adaptation performed by an Aquantia PHY. At least I can
find no indication in online documents published by Cisco which would
point towards "SGMII-2500" being an actual standard with an actual
definition, so I cannot say "yes, NXP devices support it".

vexpress_ca9x4 is seemingly the only board except for qemu_arm which
is able to run U-Boot correctly, using the `-M vexpress-a9` option to
QEMU. Building for qemu_arm and running qemu-system-arm with the `-M
virt` argument has a number of downsides, most importantly that it
only supports virtio storage drivers. This significantly reduces its
usefulness in testing memory card and Flash solutions, especially when
the tested images are from a third party source.
So therefore we reintroduce the vexpress_ca9x4 board in this commit,
with the explicit goal of using it with QEMU.
A number of differences to note from the original:
* Since the board was apparently unmaintained, I have now set myself
as the maintainer.
* The board has been converted to use the driver model, which was the
reason it was removed in the first place.
* The vexpress_ca15_tc2 and vexpress_ca5x2 boards, which were removed
in the same commit, are not necessary for the QEMU use case, and
have been omitted.
* An `mmc0` alias was introduced in the dts file. The mmc is not
detected correctly without this, now that it's based on the device
tree instead of the board's init function.
* A couple of other nodes were removed because they were problematic
when trying to run the UEFI bootmgr. Once again, the primary use
case here is QEMU, and these nodes are not needed for that to work.
* Unnecessary board init code has been removed, thanks to driver model
and device tree.
* `CONFIG_OF_EMBED` has been enabled. I know this goes against
recommended practice, but there doesn't seem to be any other way to
pass the dtb to U-Boot in the QEMU scenario. Using the -dtb argument
does not work, I suppose because U-Boot doesn't use the same
mechanics as the kernel when it's booting.
* Load addresses have been changed to fit QEMU use case.
People wanting to get a more detailed, yet somewhat isolated, diff
between this and the original, can run this command:

Note that memmove is also handled by the memcpy function.
Please note that when adding these optimized functions as default memset
memcpy functions in U-Boot, U-Boot fails to boot on the LX2160ARDB.
After the initial ATF output, no U-Boot output is shown on the serial
console. Some exception is triggered here in the very early boot process
as some of the assembler opcodes need the caches to be enabled.
Because of this, a follow-up patch will add a check to use a simple

This function is clearly architecture specific code, not board specific
code. The only difference from the previous arm arch_lmb_reserve() is the
extra reservation of 16k of memory below the stack bottom, rather than
the 4k. The common code now also uses 16k alignment. Remove this custom
implementation, as it now behaves exactly as the common code.

According to input NXP, the 4k alignment is not always sufficient.
Currently iMX works around this problem by implementing board specific
LMB reservation, however it is likely this could also occur on other
systems. Increase the LMB reservation alignment to 16k by default.

The arch_lmb_reserve() is called by lib/lmb.c lmb_reserve_common() even
if CMD_BOOTM is not enabled. However, the arc variant of arch_lmb_reserve()
is only compiled in if CMD_BOOTM is enabled.
This currently does not trigger build error, because there is an empty

With Device Manager firmware in an elf file form, we cannot load the FIT
image to the exact same address as any of the executable sections of the
elf file itself is located.
However, the device tree descriptions for the ARMV8 bootloader/OS
includes DDR regions only the final sections in DDR where the Device
Manager firmware is actually executing out of.
As the R5 uC is usually operating at a slower rate than an ARMv8 MPU,
by starting the Armv8 ahead of parsing the elf and copying the correct
sections to the required memories creates a race condition where the
ARMv8 could overwrite the elf image loaded from the FIT image prior to
the R5 completing parsing and putting the correct sections of elf in
the required memory locations. OR create rather obscure debug conditions
where data in the section is being modified by ARMV8 OS while the elf
copy is in progress.
To prevent all these conditions, lets make sure that the elf parse and
copy operations are completed ahead of ARMv8 being released to execute.
We will pay a penalty of elf copy time, but that is a valid tradeoff in
comparison to debug of alternate scenarios.

NB0 is bridge to SRAM and NB1 is bridge to DDR.
To ensure that SRAM transfers are not stalled due to delays during DDR
refreshes, SRAM traffic should be higher priority (threadmap=2) than
DDR traffic (threadmap=0).
This fixup is critical to provide deterministic access latency to
MSMC from ICSSG, it applies to all AM65 silicon revisions and is due
to incorrect reset values (has no erratum id) and statically setting
things up should be done independent of usecases and board.
This specific style of Northbridge configuration is specific only to
AM65x devices, follow-on K3 devices have different data prioritization
schemes (ASEL and the like) and hence the fixup applies purely to
AM65x.
Without this fix, ICSSG TX lock-ups due to delays in MSMC transfers in
case of SR1 devices, on SR2 devices, lockups were not observed so far
but high retry rates of ICSSG Ethernet (icssg-eth) and, thus, lower
throughput.

As explained by Wolfgang, historically PowerPC would do a number of
things to hand-optimize placement of the binary on NOR flash in order to
maximize utilization of very scarce resources. These days, we simply
aren't optimizing our binary layout for NOR flash placement and it's
quite likely this wasn't working as intended. Furthermore, this level
of optimization makes it difficult to have version_string be a global,
instead of a weak and overridden value, and so make more progress on
reproducible builds, which is a current concern.
Move to having PowerPC no longer store version_string in the early part
of text so that it might be part of the first page of NOR and instead
use the same declaration everyone else does.

some platforms are old enough to support both, but are well supported by

because some of the ATAGs related functions have been re-used to provide
the same kind of information, but for devicetree or just generally to
inform the user. When needed still, rename these functions to
get_board_revision() instead, to avoid conflicts. In other cases, these

When booting in EFI, lib/efi_loader/efi_memory.c calls
board_get_usable_ram_top(0) which returns by default
gd->ram_base + gd->ram_size which is the top of DDR.
In case of OPTEE boot, the top of DDR is currently reserved by OPTEE,
board_get_usable_ram_top(0) must return an address outside OPTEE
reserved memory.
gd->ram_top matches this constraint as it has already been initialized
by substracting all DT reserved-memory (included OPTEE memory area).

For ARMv8-A, NEON is standard, so the compiler can use it even when no
special target flags are provided. For example, it can use stores from
NEON registers to zero-initialize large structures. GCC 11 decides to
do this inside the DRAM init code for the Allwinner H6.
However, GCC 11 has a bug where it generates misaligned NEON register
stores even with -mstrict-align. Since the MMU is not enabled this early
in SPL, the misaligned store causes an exception and breaks booting.
Work around this issue by restricting the compiler to using GPRs only,
not vector registers. This prevents any future surprises relating to
NEON use as well.

Use the environment variable armv8_switch_to_el1 to determine whether
to switch to EL1 at runtime. This is an alternative to the
CONFIG_ARMV8_SWITCH_TO_EL1 compile-time option.
The environment variable will be ineffective if the ARMV8_MULTIENTRY
config is used.
This is required by the Armv8r64 architecture, which must be able to
boot at S-EL1 for Linux but may need to boot at other ELs for other
systems.

The BASER_FVP board variant is implemented on top of the BASE_FVP board
config (which, in turn, is based on the Juno Versatile Express board
config). They all share a similar memory map - for BASER_FVP the map is
inverted from the BASE_FVP
(https://developer.arm.com/documentation/100964/1114/Base-Platform/Base---memory/BaseR-Platform-memory-map)
* Create new TARGET_VEXPRESS64_BASER_FVP target, which uses the same
board config as BASE_FVP and JUNO
* Adapt vexpress_aemv8a.h header file to support BASER_FVP (and rename
to vexpress_aemv8.h)
* Enable config to switch to EL1 for the BASER_FVP
* Create vexpress_aemv8r defconfig
* Provide an MPU memory map for the BASER_FVP
For now, only single core boot is supported.

Armv8r64 is the first Armv8 platform that only has a PMSA at the
current exception level. The architecture supplement for Armv8r64
describes new fields in ID_AA64MMFR0_EL1 which can be used to detect
whether a VMSA or PMSA is present. These fields are RES0 on Armv8a.
Add logic to read these fields and, for the protection of the memory
used by U-Boot, initialize the MPU instead of the MMU during init, then
clear the MPU regions before transition to the next stage.
Provide a default (blank) MPU memory map, which can be overridden by
board configurations.

On Armv8-R, the EL1&0 memory system architecture is configurable as a
VMSA or PMSA, and resets to an "architecturally unknown" value.
Add code to armv8_switch_to_el1_m which detects whether the MSA at
EL1&0 is configurable using the id_aa64mmfr0_el1 register MSA fields.
If it is we must ensure the VMSA is enabled so that a rich OS can boot.
The MSA and MSA_FRAC fields are described in the Armv8-R architecture
profile supplement (section G1.3.7):

The use of ARMv8.3 pointer authentication (PAuth) is governed by fields
in HCR_EL2, which trigger a 'trap to EL2' if not enabled. The reset
value of these fields is 'architecturally unknown' so we must ensure
that the fields are enabled (to disable the traps) if we are entering
the kernel at EL1.
The APK field disables PAuth instruction traps and the API field
disables PAuth register traps
Add code to disable the traps in armv8_switch_to_el1_m. Prior to doing
so, it checks fields in the ID_AA64ISAR1_EL1 register to ensure pointer
authentication is supported by the hardware.
The runtime checks require a second temporary register, so add this to
the EL1 transition macro signature and update 2 call sites.

The logic in msm_generate_mac_addr() was originally taken from the LK
bootloader where the serial number is a string and must be parsed first.
However, in U-Boot msm_board_serial() returns an u32 and
msm_generate_mac_addr() has quite complicated code that will first
print it as a hex string and then immediately parse it again.
What this function actually does at the end is to put the serial number
encoded as big endian (the order used for the hex string) into the u8 *mac.
Use put_unaligned_be32() to do that with bit shifts instead of going
through the string format.
This should be slightly more efficient and cleaner but does not result
in any functional difference.

At the moment U-Boot produces an empty MAC address (02:00:00:00:00:00)
if the eMMC is not used by anything in U-Boot (e.g. with
CONFIG_ENV_IS_NOWHERE=y instead of having the environment on eMMC).
This happens because then there is nothing that actually initializes
the eMMC and reads the "cid" that is later accessed.
To fix this, call mmc_init() to ensure the eMMC is initialized.
There is no functional difference if the eMMC is already initialized
since then mmc_init() will just return without doing anything.

A U-Boot image could be loaded and executed at a different
location than it was linked at.
For example, Aspeed takes a stable release version of U-Boot image
as the golden one for recovery purposes. When the primary storage
such as flash is corrupted, the golden image would be loaded to any
SRAM/DRAM address on demands through ethernet/UART/etc and run for
rescue.
To deal with this condition, the PIE is needed as there is only one
signed, golden image, which could be however executed at different
places.
This patch adds the PIE support for ARMv7 platform.

Over the time, the "stemmy" U-Boot board was tested on several other
Samsung smartphones based on ST-Ericsson NovaThor Ux500. Convert the
documentation to reStructuredText at doc/board/ste/stemmy.rst and
make the device list complete. Also note that the board now boots
into USB Fastboot instead of just ending up at the U-Boot prompt.
The device table is mostly taken from the postmarketOS wiki article
(https://wiki.postmarketos.org/wiki/ST-Ericsson_NovaThor_U8500).
All the newly added devices were tested by Linus Walleij.

Make use of the new drivers for ARM U8500 introduced in the U-Boot
2021.10 merge window by adding basic support for USB Fastboot with
the "stemmy" board. As a first step this will always boot directly
into USB Fastboot for now with the console displayed on the screen
to make that obvious.
Samsung uses quite strange GPT partition labels on these boards,
so also add a bunch of fastboot_partition_alias_* to make this more
easy to use.

So far there is no need for a clock driver in U-Boot because the
previous boot stage leaves all the necessary clocks on. However,
some drivers in U-Boot (e.g. arm_pl180_mmci) depend on having a clock
driver to obtain the clock frequency.
Setting up the clock drivers properly is a bit tricky on U8500,
so for now add a simple fixed-clock for the eMMC that allows obtaining
the clock frequency. This should be replaced eventually if some board
actually requires enabling some of the clocks.

Update ste-dbx5x0.dtsi, ste-ab8500.dtsi and ste-ab8505.dtsi with

https://git.kernel.org/pub/scm/linux/kernel/git/linusw/linux-nomadik.git/
branch "ux500-dts-for-v5.15" (pending merge for Linux 5.15).
The only relevant change for U-Boot here is
"ARM: dts: ux500: ab8500: Link USB PHY to USB controller node" [1]
which links the USB PHY to the USB controller. This is necessary on
U-Boot because the PHY driver is implemented as part of the generic
PHY subsystem that makes use of these bindings.
