Commit 5bb2c550b1 ("arm: mvebu: Move internal registers in
arch_very_early_init() function") moved code from file cpu.c to lowlevel.c,
which moves Marvell internal registers from address INTREG_BASE_ADDR_REG to
SOC_REGS_PHY_BASE.
But the steps describing how to do it correctly were documented only in
older U-Boot versions and commit cefd764222 ("arm: mvebu: Fix internal
register config on A38x") probably unintentionally removed important
details about MMU from code comments around.
Commit 5bb2c550b1 ("arm: mvebu: Move internal registers in
arch_very_early_init() function") implemented code movement according to
(now incomplete) comments which resulted in semi-broken code.
The result is that I-cache is currently disabled for all Armada 38x boards
and maybe there are some other (unreported / undetected) issues.
Reimplement it correctly. First flush all caches, then disable MMU and L2
cache and then move Marvell internal registers. There is no need to
explicitly disable I-cache.
After this change lzmadec command with lzma image of 0x7000000 bytes is
doing decompression just 5 seconds. Before this change it was 30 seconds.
To make lowlevel.S code more readable, extend asm/pl310.h header file to be
compatible with assembler and use macros from this file.

LTO (Link-Time Optimisation) is an very useful feature which can
significantly reduce the size of U-Boot binaries. So far it has been
made available for selected ARM boards and sandbox.
However, incremental builds are much slower when LTO is used. For example,
an incremental build of sandbox takes 2.1 seconds on my machine, but 6.7
seconds with LTO enabled.
Add a NO_LTO parameter to the build, similar to NO_SDL, so it can be
disabled during development if needed, for faster builds.
Add some documentation about LTO while we are here.

There is currently a problem that U-Boot can not work on ARMv4
because assembly imlementations of memcpy() and some other functions
use "bx lr" instruction that is not available on ARMv4 ("mov pc, lr"
should be used instead).
A working preprocessor-based solution to this problem is found in
arch/arm/lib/relocate.S. Move it to the "ret" macro in
arch/arm/include/asm/assembler.h and change all "bx lr" code
to "ret lr" in functions that may run on ARMv4. Linux source code
deals with this problem in the same manner.

The ROM API is thoroughly undocumented, but apparently passing the xor
of the real arguments as an extra argument is required [1]. Also, we
need to do the "save gd/restore gd" dance. These are both error-prone,
and lead to a lot of code duplication.
Since both imx8m[np] and imx8ulp SOCs have this, add a separate
translation unit which is included precisely when the new
CONFIG_IMX8_ROMAPI symbol is set, which provide convenience wrappers
that take care of computing the xor value as well as doing the gd
dance, and that thus have a more intuitive API. Subsequent patches
will make use of these to reduce boilerplate.
[1] One wonders, for example, if the check is only applied to the
lower 32 bits, or if we're implicitly relying on all 64-bit pointer
values we're passing effectively have 0 in the upper 32 bits.

The NVMe firmware in the macOS 13 beta blocks or crashes with u-boot's
current minimal RTKit implementation. It does not provide buffers for
the firmware's buffer requests. The ANS2 firmware included in macOS 11
and 12 tolerates this. The firmware included in the first macOS 13 beta
requires buffers for the crashlog and ioreport endpoints to function.
In the case of the NVMe the buffers are physical memory. Access to
physical memory is guarded by what Apple calls SART.
Import m1n1's SART driver (exclusively used for the NVMe controller).
Implement buffer management helpers for RTKit. These are generic since
other devices (none in u-boot so far) require different handling.

Currently get_tcr() takes an "el" parameter, to select the proper
version of the TCR_ELx system register.
This is problematic in case of the Apple M1, since it runs with
HCR_EL2.E2H fixed to 1, so TCR_EL2 is actually using the TCR_EL1 layout,
and we get the wrong version.
For U-Boot's purposes the only sensible choice here is the current
exception level, and indeed most callers treat it like that, so let's
remove that parameter and read the current EL inside the function.
This allows us to check for the E2H bit, and pretend it's EL1 in this
case.
There are two callers which don't care about the EL, and they pass 0,
which looks wrong, but is irrelevant in these two cases, since we don't
use the return value there. So the change cannot affect those two.

The AArch64 TCR_ELx register is a 64-bit register, and many newer
architecture features use bits in the upper half. So far U-Boot was
igorant of those bits, trying to leave them alone.
However, in an effort to set bit 31 to 1, it failed doing so, because
the compiler sign-extended "1 << 31", so that all bits[63:31] got set.
Older ARMv8.0 cores don't define anything dangerous up there, but newer
architecture revisions do, and setting all those bits will end badly:
=================
$ qemu-system-aarch64 -cpu max ....
U-Boot 2022.07-rc1 (May 09 2022 - 15:21:00 +0100)
DRAM: 1.5 GiB
================= (hangs here)
Defining TCR_ELx_RSVD to "1U << 31" avoids the sign-extension, so all
upper bits stay at a safe 0 value. This means no more surprises when
U-Boot runs on a more capable CPU core.

type. However, the version in drivers/ddr/imx/imx8m/ddrphy_utils.c
differs from the private one used by that board in how it extracts the
byte value, and I was only getting zeroes. Adding a bit of debug
printf'ing gives me
tmp = 0x00ffff00
tmp = 0x00070700
tmp = 0x00000000
tmp = 0x00101000
and indeed I was expecting a (combined) value of 0xff070010 (0xff
being Manufacturer ID for Micron). I can't find any documentation that
says how the values are supposed to be read, but clearly the iot-gate
definition is the right one, both for its use case as well as my
imx8mp-based board.
So lift the private definition of lpddr4_mr_read() from the
imx8mm-cl-iot-gate board code to ddrphy_utils.c, and add a declaration
in the ddr.h header where e.g. get_trained_CDD() is already declared.
This has only been compile-tested for the imx8mm-cl-iot-gate
board (since I don't have the hardware), but since I've merely moved
its definition of lpddr4_mr_read(), I'd be surprised if it changed
anything for that board.

Note that the ge_bx50v3 board uses CONFIG_PCIE_IMX_POWER_GPIO and does

Add the clock driver for the rk3066 platform.
Derived from the rk3288 and rk3188 driver it
supports only a bare minimum to bring up the system
to reduce the TPL size for:
SDRAM clock configuration.
The boot devices NAND, EMMC, SDMMC, SPI.
A UART for the debug messages (fixed) at 115200n8.
A SARADC for the recovery button.
A TIMER for the delays (fixed).
There's support for two possible frequencies,
the safe 600MHz which will work with default pmic settings and
will be set to get away from the 24MHz default and
the maximum of 1.416Ghz, which boards can set if they
were able to get pmic support for it.
After the clock tree is set during the TPL probe
there's no parent update support.
In OF_REAL mode the drivers ns16550.c and dw-apb-timer.c
obtain the (fixed) clk_get_rate from the clock driver
instead of platdata.
The rk3066 cru node has a number of assigned-clocks properties
that call the .set_rate() function. Add them to the list so that
they return a 0 instead of -ENOENT.

This adds a boot method for loading the next stage from the host. It is
mostly modeled off of spl_load_image_ext. I am not really sure why/how
spl_load_image_fat uses three different methods to load the image, but
the simple case seems to work OK for now.
To control the presence of this boot method, we add a config symbol.
While we're at it, we update the original semihosting config symbol.
I think semihosting has some advantages of other forms of JTAG boot.
Common other ways to boot from JTAG include:
- Implementing DDR initialization through JTAG (typically with dozens of
lines of TCL) and then loading U-Boot. The DDR initialization
typically uses hard-coded register writes, and is not easily adapted
to different boards. BOOT_DEVICE_SMH allows booting with SPL,
leveraging U-Boot's existing DDR initialization code. This is the
method used by NXP's CodeWarrior IDE on Layerscape processors (see
AN12270).
- Loading a bootloader into SDRAM, waiting for it to initialize DDR, and
then loading U-Boot. This is tricky, because the debugger must stop the
boot after the bootloader has completed its work. Trying to load
U-Boot too early can cause failure to boot. This is the method used by
Xilinx with its Zynq(MP) processors.
- Loading SPL with BOOT_DEVICE_RAM and breaking before SPL loads the
image to load U-Boot at the appropriate place. This can be a bit
tricky, because the load address is dependent on the header size. An
elf with symbols must also be used in order to stop at the appropriate
point. BOOT_DEVICE_SMH can be viewed as an extension of this process,
where SPL automatically stops and tells the host where to place the
image.

In contrast to other Allwinner SoCs the F1C100s BROM does not store a
boot source indicator in the eGON header in SRAM. This leaves the SPL
guessing where we were exactly booted from, and for instance trying
the SD card first, even though we booted from SPI flash.
By inspecting the BROM code and by experimentation, Samuel found that the
top of the BROM stack contains unique pointers for each of the boot
sources, which we can use as a boot source indicator.
This patch removes the existing board_boot_order bodge and replace it
with a proper boot source indication function.
The only caveat is that this only works in the SPL, as the SPL header
gets overwritten with the exception vectors, once U-Boot proper takes
over. Always return MMC0 as the boot source, when called from U-Boot
proper, as a placeholder for now, until we find another way.

The branch_if_master macro jumps to a label if the CPU is the "master"
core, which we define as having all affinity levels set to 0. To check
for this condition, we need to mask off some bits from the MPIDR
register, then compare the remaining register value against zero.
The implementation of this was slighly broken (it preserved the upper
RES0 bits), overly complicated and hard to understand, especially since
it lacked comments. The same was true for the very similar
branch_if_slave macro.
Use a much shorter assembly sequence for those checks, use the same
masking for both macros (just negate the final branch), and put some
comments on them, to make it clear what the code does.
This allows to drop the second temporary register for branch_if_master,
so we adjust all call sites as well.
Also use the opportunity to remove a misleading comment: the macro
works fine on SoCs with multiple clusters. Judging by the commit
message, the original problem with the Juno SoC stems from the fact that
the master CPU *can* be configured to be from cluster 1, so the
assumption that the master CPU has all affinity values set to 0 does not
hold there. But this is already mentioned above in a comment, so remove
the extra comment.

The ARMv8 architecture describes the "SError interrupt" as the fourth
kind of exception, next to synchronous exceptions, IRQs, and FIQs.
Those SErrors signal exceptional conditions from which the system might
not easily recover, and are normally generated by the interconnect as a
response to some bus error. A typical situation is access to a
non-existing memory address or device, but it might be deliberately
triggered by a device as well.
The SError interrupt replaces the Armv7 asynchronous abort.
Trusted Firmware enters U-Boot (BL33) typically with SErrors masked,
and we never enable them. However any SError condition still triggers
the SError interrupt, and this condition stays pending, it just won't be
handled. If now later on the Linux kernel unmasks the "A" bit in PState,
it will immediately take the exception, leading to a kernel crash.
This leaves many people scratching their head about the reason for
this, and leads to long debug sessions, possibly looking at the wrong
places (the kernel, but not U-Boot).
To avoid the situation, just unmask SErrors early in the ARMv8 boot
process, so that the U-Boot exception handlers reports them in a timely
manner. As SErrors are typically asynchronous, the register dump does
not need to point at the actual culprit, but it should happen very
shortly after the condition.
For those exceptions to be taken, we also need to route them to EL2,
if U-Boot is running in this exception level.
This removes the respective code snippet from the Freescale lowlevel
routine, as this is now handled in generic ARMv8 code.

We do this by consolidating the SYS_IMMR options we have and providing

The bulk of it is Samuel's DM_I2C rework, which removes the nasty I2C
deprecation warnings for most 32-bit boards. It also includes some
smaller refactorings that pave the way for more changes, mostly driven
by needing to support the Allwinner RISC-V SoC later on.
Board wise we gain support for the FriendlyARM NanoPi R1S H5 router
board and official Pinetab support.
Build-tested for all 160 sunxi boards, and boot tested on a A64, A20,
H3, H6, and H616 board. USB, SD card, eMMC, and Ethernet all work there
(where applicable).
The patch enables spread spectrum clocking (SSC) for MPU and LCD PLLs.
As reported by the TI spruh73x/spruhl7x RM, SSC is only supported for
the DISP/LCD and MPU PLLs on am33xx/am43xx. SSC is not supported for
DDR, PER, and CORE PLLs.
Calculating the required values and setting the registers accordingly
was taken from the set_mpu_spreadspectrum routine contained in the
arch/arm/mach-omap2/am33xx/clock_am33xx.c file of the u-boot project.
In locked condition, DPLL output clock = CLKINP *[M/N]. In case of
SSC enabled, the reference manual explains that there is a restriction
of range of M values. Since the clk_ti_am3_dpll_round_rate() attempts
to select the minimum possible N, the value of M obtained is not
guaranteed to be within the range required. With the new "ti,min-div"
parameter it is possible to increase N and consequently M to satisfy the
constraint imposed by SSC.

Only one board, Yones Toptech BD1078, actually uses a non-default MMC
pinmux. All other uses of these symbols select the default value or an
invalid value. To simplify things, remove support for the unused pinmux
options, and convert the remaining option to a Boolean.
This allows the pinmux to be chosen by the preprocessor, instead of
having the code parse a string at runtime (for a build-time option!).
Not only does this reduce code size, but it also allows this Kconfig
option to be used in a table-driven DM pinctrl driver.

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

Provide a default (blank) MPU memory map, which can be overridden by

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.
