On STMicroelectronics boards, the UART can reliably go up to
2000000 bauds when connected to the on-board ST-LINK-V2 for STM32MP15
Unfortunately U-Boot will fall back to 115200 unless higher rates are
declared via CONFIG_SYS_BAUDRATE_TABLE.
This patch add the support of higher baudrates on STMicroelectronics
boards with ST-LINK.

Currently we don't support sha384/512 for the X.509 certificate

Rework the code a bit and fix it by adding an array of structs with the

of hardcoding the GUID types.

Currently, in case of arm64 bootloader and U-Boot the stack pointer is
initialized at an offset of NON_SECURE_MSRAM_SIZE from arm64 SPL's text
base address. After jumping to arm64, execution is done out of DDR.
Therefore, having an offset corresponding to the size of MSRAM does not
have any significance.
Instead, initialize the stack pointer after an offset of 4MB from the SPL
text base address. This helps in allocating larger memory for stack.

Under the current implementation, booting from removable media using
a architecture-specific default image name, say BOOTAA64.EFI, is
supported only in distro_bootcmd script. See the commit 74522c898b
("efi_loader: Add distro boot script for removable media").
This is, however, half-baked implementation because
1) UEFI specification requires this feature to be implemented as part
of Boot Manager's responsibility:
3 - Boot Manager
3.5.1 Boot via the Simple File Protocol
When booting via the EFI_SIMPLE_FILE_SYSTEM_PROTOCOL, the FilePath will
start with a device path that points to the device that implements the
EFI_SIMPLE_FILE_SYSTEM_PROTOCOL or the EFI_BLOCK_IO_PROTOCOL. The next
part of the FilePath may point to the file name, including
subdirectories, which contain the bootable image. If the file name is
a null device path, the file name must be generated from the rules
defined below.
...
3.5.1.1 Removable Media Boot Behavior
To generate a file name when none is present in the FilePath, the
firmware must append a default file name in the form
\EFI\BOOT\BOOT{machine type short-name}.EFI ...
2) So (1) entails the hehavior that the user's preference of boot media
order should be determined by Boot#### and BootOrder variables.
With this patch, the semantics mentioned above is fully implemented.
For example, if you want to boot the system from USB and SCSI in this
order,
* define Boot0001 which contains only a device path to the USB device
(without any file path/name)
* define Boot0002 which contains only a device path to the SCSI device,
and
* set BootOrder to Boot0001:Boot0002
To avoid build error for sandbox, default file name "BOOTSANDBOX.efi"
is defined even if it is out of scope of UEFI specification.

U-Boot provides a verified-boot feature based around FIT, but there is
no standard way of implementing it for a board. At present the various
required pieces must be built up separately, to produce a working
implementation. In particular, there is no built-in support for selecting
A/B boot or recovery mode.
This series introduces VPL, a verified program loader phase for U-Boot.
Its purpose is to run the verified-boot process and decide which SPL
binary should be run. It is critical that this decision happens before
SPL runs, since SPL sets up SDRAM and we need to be able to update the
SDRAM-init code in the field.
Adding VPL into the boot flow provides a standard place to implement
verified boot. This series includes the phase itself, some useful Kconfig
options and a sandbox_vpl build for sandbox. No verfied-boot support is
provided in this series.
Most of the patches in this series are fixes and improvements to docs and
various Kconfig conditions for SPL.
Add support for VPL, a new phase of U-Boot. This runs after TPL. It is
responsible for selecting which SPL binary to run, based on a

The bootflow feature provide a built-in way for U-Boot to automatically
boot an Operating System without custom scripting and other customisation.
This is called 'standard boot' since it provides a standard way for
U-Boot to boot a distro, without scripting.
It introduces the following concepts:
- bootdev - a device which can hold a distro
- bootmeth - a method to scan a bootdev to find bootflows (owned by
U-Boot)
- bootflow - a description of how to boot (owned by the distro)
This series provides an implementation of these, enabled to scan for
bootflows from MMC, USB and Ethernet. It supports the existing distro
boot as well as the EFI loader flow (bootefi/bootmgr). It works
similiarly to the existing script-based approach, but is native to
U-Boot.
With this we can boot on a Raspberry Pi 3 with just one command:
bootflow scan -lb
which means to scan, listing (-l) each bootflow and trying to boot each
one (-b). The final patch shows this.
With a standard way to identify boot devices, booting become easier. It
also should be possible to support U-Boot scripts, for backwards
compatibility only.
...
The design is described in these two documents:

Merge tag 'efi-2022-07-rc1-3' of https://source.denx.de/u-boot/custodians/u-boot-efi
Pull request for efi-2022-07-rc1-3
Documentation:
* Document image size parameter of bootefi command
UEFI:
* avoid building partition support in SPL/TPL where not required
* improve integration of EFI subsystem and driver model
* restore ability to boot arbitrary blob
In include/blk.h, Simon suggested:
===>
/*
* These functions should take struct udevice instead of struct blk_desc,
* but this is convenient for migration to driver model. Add a 'd' prefix
* to the function operations, so that blk_read(), etc. can be reserved for
* functions with the correct arguments.
*/
unsigned long blk_dread(struct blk_desc *block_dev, lbaint_t start,
lbaint_t blkcnt, void *buffer);
unsigned long blk_dwrite(struct blk_desc *block_dev, lbaint_t start,
lbaint_t blkcnt, const void *buffer);
unsigned long blk_derase(struct blk_desc *block_dev, lbaint_t start,
lbaint_t blkcnt);
<===
So new interfaces are provided with this patch.
They are expected to be used everywhere in U-Boot at the end.
The exceptions are block device drivers, partition drivers and efi_disk
which should know details of blk_desc structure.

Add efi_disk_probe() function.
This function creates an efi_disk object for a raw disk device (UCLASS_BLK)
and additional objects for related partitions (UCLASS_PARTITION).
So this function is expected to be called through driver model's "probe"
interface every time one raw disk device is detected and activated.
We assume that partition devices (UCLASS_PARTITION) have been created
when this function is invoked.
Signed-off-by: AKASHI Takahiro <takahiro.akashi@linaro.org>
In the next commit, CONFIG_EFI_SETUP_EARLY will become mandated
in order to support dynamic enumeration of efi_disk objects.
This can, however, be problematic particularly in case of file-based
variable storage (efi_variable.c, default).
Non-volatile variables are to be restored from EFI system partition
by efi_init_variables() in efi_init_obj_list(). When efi_init_obj_list()
is called in board_init_r(), we don't know yet what disk devices
we have since none of device probing commands (say, scsi rescan) has not
been executed at that stage.
So in this commit, a preparatory change is made; efi_init_obj_list() is
broken into the two functions;
* efi_init_early(), and
* new efi_init_obj_list()
Only efi_init_early() will be called in board_init_r(), which allows
us to execute any of device probing commands, either though "preboot"
variable or normal command line, before calling efi_init_obj_list() which
is to be invoked at the first execution of an efi-related command
(or at efi_launch_capsules()) as used to be.

Some defconfig enables CMD_PART even if none of any partition table
types (CONFIG_*_PARTITION) are enabled.
This will lead to the size growth in SPL/TPL code since disk/part.c
will be compiled in any way.
We will change disk/Kconfig later so that CONFIG_PARTITIONS is only
enabled when, at least, one of CONFIG_*_PARTITION is enabled.
To make the build work (in particular, "part" command) correctly,
a few functions should be defined as void functions in case of
!CONFIG_PARTITIONS.

Since CONFIG_[SPL|TPL]_PARTITIONS were introduced, part.h has not been
updated. Due to this, while the build won't fail, some functionality may
possibly break as some partition-related functions are nullified even
though some partition table types are enabled for SPL/TPL.

and fall back on $fdtcontroladdr if not set/invalid:
if fdt addr ${fdt_addr_r}; then

If the `fdt addr` test fails, it prints the following message on the
console, suggesting there is an error when there is not:
libfdt fdt_check_header(): FDT_ERR_BADMAGIC

Currently there is only one way to override desired environment location,
by implementing env_get_location(). This is increasingly being conflated
both on board level and architecture level, which leads to a problem on
boards where this function is already implemented on architecture level,
since those boards have no way to override this environment location on
board level anymore.
Implement arch_env_get_location() function which is architecture specific
and should only ever be implemented in architecture code. This function
has lower priority than env_get_location(), which should only ever be
implemented in board code, and which overrides the arch_env_get_location()
architecture environment selection.
This way, architecture can define its default environment chooser, while
board can now override it as needed at all times.
There is no functional change, since env_get_location() simply returns
arch_env_get_location(), and arch_env_get_location() implements the
current env_get_location() default content.

When every member of a linker list is aligned by the compiler, we can no
longer rely on the sizeof of the struct to determine the number of
entries.
For example, if the struct size is 0x90 but every entry is aligned to 0xa0
by the compiler, the linker list entries takes more space in memory and
the calculation of the number of entries is incorrect. For example, we may
see 0x12 entries when there are only 0x11.
This is a real problem. There may be a general solution, although I cannot
currently think of one. So far it only bites with OF_PLATDATA_RT which
creates a pointer to each entry of the 'struct udevice' linker_list. This
does not happen without that option, so it only affects SPL.
Work around it by manually calculating the aligned size of struct udevice,
then using that for the n_ent calculation.

Signed-off-by: Tom Rini <trini@konsulko.com>
Currently, add_mtd_partitions_of() can be used only if dev field of
mtd_info struct is populated. It's the case, for example, for a spi nor
flash, which has a DT compatible "jedec,spi-nor" and an associated
device. mtd->dev is populated in spi_nor_scan().
But in case of a raw nand node, mtd_info's dev field can't be populated
as flash node has no compatible, so no associated device.
add_mtd_partitions_of() can't be used to parse "partitions" subnode.
To remove this constraint, add an ofnode field in mtd_info struct
which reference the DT flash node. This new field is populated by
nand_scan_tail(). This new field will be used by add_mtd_partitions_of()
to parse the flash node for "partitions" defined in DT.

This annotates malloc and friends so that valgrind can track the heap. To
do this, we need to follow a few rules:
* Call VALGRIND_MALLOCLIKE_BLOCK whenever we malloc something
* Call VALGRIND_FREELIKE_BLOCK whenever we free something (generally after
we have done our bookkeeping)
* Call VALGRIND_RESIZEINPLACE_BLOCK whenever we change the size of an
allocation. We don't record the original request size of a block, and
neither does valgrind. For this reason, we pretend that the old size of
the allocation was for 0 bytes. This marks the whole allocaton as
undefined, so in order to mark all bits correctly, we must make the whole
new allocation defined with VALGRIND_MAKE_MEM_DEFINED. This may cause us
to miss some invalid reads, but there is no way to detect these without
recording the original size of the allocation.
In addition to the above, dlmalloc itself tends to make a lot of accesses
which we know are safe, but which would be unsafe outside of dlmalloc. For
this reason, we provide a suppression file which ignores errors ocurring in
dlmalloc.c

Valgrind uses magic code sequences to define an ABI that the client may use
to request behavior from the host. In particular, this may be used to
inform valgrind about custom allocators, such as the one used in U-Boot.
This adds headers defining these sequences to U-Boot. It also adds a config
option to disable emission of these sequences entirely, in the (likely)
event that the user does not wish to use valgrind. Note that this option is
called NVALGRIND upstream, but was renamed (and inverted) to
CONFIG_VALGRIND. Aside from this and the conversion of a few instances of
VALGRIND_DO_CLIENT_REQUEST_EXPR to STMT, these headers are unmodified.
These headers were copied from valgrind 3.16.1-4 as distributed in Arch
Linux. They are licensed with the bzip2 1.16 license. This appears to be a
BSD license with some clauses from Zlib.

Currently we require PHY interface mode to be known when
finding/creating the PHY - the functions
* phy_connect_phy_id()
* phy_device_create()
* create_phy_by_mask()
* search_for_existing_phy()
* get_phy_device_by_mask()
* phy_find_by_mask()
all require the interface parameter, but the only thing done with it is
that it is assigned to phydev->interface.
This makes it impossible to find a PHY device without overwriting the
set mode.
Since the interface mode is not used during .probe() and should be used
at first in .config(), drop the interface parameter from these
functions. Make the default value of phydev->interface (in
phy_device_create()) to be PHY_INTERFACE_MODE_NA. Move the interface
parameter to phy_connect_dev(), where it should be.
Change all occurrences treewide. In occurrences where we don't call
phy_connect_dev() for some reason (they only configure the PHY without
connecting it to an ethernet controller), set
phydev->interface = value from phy_find_by_mask call.

A big part is the DM pinctrl driver, which allows us to get rid of quite
some custom pinmux code and make the whole port much more robust. Many
thanks to Samuel for that nice contribution! There are some more or less
cosmetic warnings about missing clocks right now, I will send the trivial

Another big chunk is the mkimage upgrade, which adds RISC-V and TOC0
(secure images) support. Both features are unused at the moment, but I
have an always-secure board that will use that once the DT lands in the
kernel.
On top of those big things we have some smaller fixes, improving the
I2C DM support, fixing some H6/H616 early clock setup and improving the
eMMC boot partition support.
The gitlab CI completed successfully, including the build test for all
161 sunxi boards. I also boot tested on a A64, A20, H3, H6, and F1C100
board. USB, SD card, eMMC, and Ethernet all work there (where applicable).

* Introduce a "ti,ecc-enable" flag which allows a memorycontroller
instance to enable ecc.
* Introduce functionality to properly program the DDRSS registers to

U-boot is intended to replace linux kernel in android boot image(ABL), and
it's FIT payload to replace initramfs file. The boot process is similar to
boot image with linux:
- android bootloader (ABL) unpacks android boot image
- ABL sets `linux,initrd-start property` in chosen node in unpacked FDT
- ABL sets x0 register to FDT address, and passes control to u-boot
- u-boot reads x0 register, and stores it in `prevbl_fdt_addr` env variable
- u-boot reads `linux,initrd-start` property,
and stores it in `prevbl_initrd_start_addr`
In this way, u-boot bootcmd relies on `prevbl_initrd_start_addr` env
variable, and boils down to `bootm $prevbl_initrd_start_addr`.
If more control on boot process is desired, pack a boot script in
FIT image, and put it to default configuration
What done:
- Rearrange defconfig option order
- Add CONFIG_SAVE_PREV_BL_* options
- Doc updates:
- remove wrong SBOOT memory corruption note, because
memory is changed during u-boot bringup process,
not by SBOOT
- put payload on ramdisk place in abl boot image

For most of them this is a trivial decision based on Kconfig variables,

Most Allwinner sunxi SoCs have separate boot ROMs in non-secure and
secure mode. The "non-secure" or "normal" boot ROM (NBROM) uses the
existing sunxi_egon image type. The secure boot ROM (SBROM) uses a
completely different image type, known as TOC0.
A TOC0 image is composed of a header and two or more items. One item
is the firmware binary. The others form a chain linking the firmware
signature to the root-of-trust public key (ROTPK), which has its hash
burned in the SoC's eFuses. Signatures are made using RSA-2048 + SHA256.
The pseudo-ASN.1 structure is manually assembled; this is done to work
around bugs/quirks in the boot ROM, which vary between SoCs. This TOC0

U-boot is intended to replace linux kernel in android boot image(ABL), and
it's FIT payload to replace initramfs file. The boot process is similar to
boot image with linux:
- android bootloader (ABL) unpacks android boot image
- ABL sets `linux,initrd-start property` in chosen node in unpacked FDT
- ABL sets x0 register to FDT address, and passes control to u-boot
- u-boot reads x0 register, and stores it in `prevbl_fdt_addr` env variable
- u-boot reads `linux,initrd-start` property,
and stores it in `prevbl_initrd_start_addr`
In this way, u-boot bootcmd relies on `prevbl_initrd_start_addr` env
variable, and boils down to `bootm $prevbl_initrd_start_addr`.
If more control on boot process is desired, pack a boot script in
FIT image, and put it to default configuration
What done:
- strip unneeded config options
- add FIT image support
- add framebuffer node, u-boot logo and video console
- increase LMB_MAX_REGIONS, to store all linux dtb reserved memory regions
- add linux kernel image header
Uart driver causes hang, when u-boot is used in android boot image instead
of linux. Temporary disable console driver, until investigated and fixed.

When u-boot is used as a chain-loaded bootloader (replacing OS kernel),
previous bootloader leaves data in RAM, that can be reused.
For example, on recent arm linux system, when chainloading u-boot,
there are initramfs and fdt in RAM prepared for OS booting. Initramfs
may be modified to store u-boot's payload, thus providing the ability to
use chainloaded u-boot to boot OS without any storage support.
Two config options added:
- SAVE_PREV_BL_INITRAMFS_START_ADDR
saves initramfs start address to 'prevbl_initrd_start_addr' environment
variable
- SAVE_PREV_BL_FDT_ADDR
saves fdt address to 'prevbl_fdt_addr' environment variable

Some serial drivers can be vastly more efficient when printing multiple
characters at once. Non-DM serial has had a puts option for these sorts
of drivers; implement it for DM serial as well.
Because we have to add carriage returns, we can't just pass the whole
string directly to the serial driver. Instead, we print up to the
newline, then print a carriage return, and then continue on. This is
less efficient, but it is better than printing each character
individually. It also avoids having to allocate memory just to add a few
characters.
Drivers may perform short writes (such as filling a FIFO) and return the
number of characters written in len. We loop over them in the same way
that _serial_putc loops over putc.
This results in around sizeof(void *) growth for all boards with
DM_SERIAL. The full implementation takes around 140 bytes.

If a debugger is not attached to U-Boot, semihosting calls will raise a
synchronous abort exception. Try to catch this and disable semihosting
so we can e.g. use another uart if one is available. In the immediate
case, we return an error, since it is not always possible to check for
semihosting beforehand (debug uart, user-initiated load command, etc.)
We handle all possible semihosting instructions, which is probably
overkill. However, we do need to keep track of what instruction set
we're using so that we don't suppress an actual error.
A future enhancement could try to determine semihosting capability by
inspecting the processor state. There's an example of this at [1] for
RISC-V. The equivalent for ARM would inspect the monitor modei
enable/select bits of the DSCR. However, as the article notes, an
exception handler is still helpful in order to catch disconnected
debuggers.

These functions are intended to support detecting semihosting and
falling back gracefully to alternative implementations. The test starts
by making semihosting call. SYS_ERRNO is chosen because it should not
mutate any state. If this semihosting call results in an exception
(rather than being caught by the debugger), then the exception handler
should call disable_semihosting() and resume execution after the call.
Ideally, this would just be part of semihosting by default, and not a
separate config. However, to reduce space ARM SPL doesn't include
exception vectors by default. This means we can't detect if a
semihosting call failed unless we enable them. To avoid forcing them to
be enabled, we use a separate config option. It might also be possible
to try and detect whether a debugger has enabled (by reading HDE from
DSCR), but I wasn't able to figure out a way to do this from all ELs.
This patch just introduces the generic code to handle detection. The
next patch will implement it for arm64 (but not arm32).

This adds support for booting entirely from JTAG while using a
hard-coded RCW. With these steps, it is not necessary to program a
"good" RCW using CodeWarrior. The method here can be performed with any
JTAG adapter supported by OpenOCD, including the on-board CMSIS-DAP
(albeit very slowly).
These steps require LS1046A support in OpenOCD, which was added in [1].

This adds a serial driver which uses semihosting calls to read and write
to the host's console. For convenience, if CONFIG_DM_SERIAL is enabled,
we will instantiate a serial driver. This allows users to enable this
driver (which has no physical device) without modifying their device
trees or board files. We also implement a non-DM driver for SPL, or for
much faster output in U-Boot proper.
There are three ways to print to the console:
Method Baud
================== =====
smh_putc in a loop 170
smh_puts 1600
smh_write with :tt 20000
================== =====
These speeds were measured using a 175 character message with a J-Link
adapter. For reference, U-Boot typically prints around 2700 characters
during boot on this board. There are two major factors affecting the
speed of these functions. First, each breakpoint incurs a delay. Second,
each debugger memory transaction incurs a delay. smh_putc has a
breakpoint and memory transaction for every character. smh_puts has one
breakpoint, but still has to use a transaction for every character. This
is because we don't know the length up front, so OpenOCD has to check if
each character is nul. smh_write has only one breakpoint and one memory
transfer.
DM serial drivers can only implement a putc interface, so we are stuck
with the slowest API. Non-DM drivers can implement puts, which is vastly
more efficient. When the driver starts up, we try to open :tt. Since
this is an extension, this may fail. If it does, we fall back to
smh_puts. We don't check :semihosting-features, since there are
nonconforming implementations (OpenOCD) which don't implement it (but
*do* implement :tt).
Some semihosting implementations (QEMU) don't handle READC properly. To
work around this, we try to use open/read (much like for stdin) if
possible.
There is no non-blocking I/O available, so we don't implement pending.
This will cause __serial_tstc to always return true. If
CONFIG_SERIAL_RX_BUFFER is enabled, _serial_tstc will try and read
characters forever. To avoid this, we depend on this config being
disabled.

This adds a filesystem which is backed by the host's filesystem. It is
modeled off of sandboxfs, which has very similar aims. Semihosting
doesn't support listing directories (except with SYS_SYSTEM), so neither

whole file by omitting a call to smh_seek, but this is left as a future

The ARMv8-R64 architecture introduces optional VMSA (paging based MMU)
support in the EL1/0 translation regime, which makes that part mostly
compatible to ARMv8-A.
Add a new board variant to describe the "BASE-R64" FVP model, which
inherits a lot from the existing v8-A FVP support. One major difference
is that the memory map in "inverted": DRAM starts at 0x0, MMIO is at
2GB [1].
* Create new TARGET_VEXPRESS64_BASER_FVP target, sharing most of the
exising configuration.
* Implement inverted memory map in vexpress_aemv8.h
* Create vexpress_aemv8r defconfig
* Provide an MMU memory map for the BASER_FVP
* Update vexpress64 documentation
At the moment the boot-wrapper is the only supported secure firmware. As
there is no official DT for the board yet, we rely on it being supplied
by the boot-wrapper into U-Boot, so use OF_HAS_PRIOR_STAGE, and go with
a dummy DT for now.

In preparation for the ARMv8-R64 FVP support, which has DRAM mapped at
0x0, generalise the page table generation, by using symbolic names for
the address ranges instead of fixed numbers.
We already define the base of the DRAM and MMIO regions, so just use
those symbols in the page table description. Rename V2M_BASE to the more
speaking V2M_DRAM_BASE on the way.
On the VExpress memory map, the address space right after 4GB is of no
particular interest to software, as the whole of DRAM is mapped at 32GB
instead. The first 2 GB alias to the lower 2GB of DRAM mapped below 4GB,
so we skip this part and map some more of the high DRAM, should anyone
need it.

So far the FVP model just supports booting through semihosting, so by
loading files from the host the model is running on. This allows for
quick booting of new kernels (or replacing DTBs), but prevents more
featureful boots like using UEFI.
Enable the distro_boot feature, and provide a list of possible boot
sources that U-Boot should check:
- For backwards compatibility we start with semihosting, which gets its
commands migrated from CONFIG_BOOTCOMMAND into the distro_boot
infrastructure. This is also slightly tweaked to fail graceful in case
the required files could not be found.
- Next we try to use a user provided script, that could be easily
placed into memory using the model command line.
- Since we gained virtio support with the enablement of OF_CONTROL,
let's check virtio block devices next. This is where UEFI boot can
be easily used, for instance by providing a distro installer .iso
file through virtio-blk.
- Networking is now provided by virtio as well, so enable the default
PXE and DHCP boot flows, mostly because we can.

The definition of the standard environment variables (kernel_addr_r and
friends) has been improved lately for the FVP model, but the Juno board
is still using some custom scheme.
Since we need to extend this to a third board soon, let's unify the
definition:
- Define the Juno addresses in the same generic way we do for the FVP
model, and move the actual variable setting out of the board #ifdef's.
- Add the missing addresses for a PXE file and a boot script.
- Cleanup some stale comments on the way.
As the FVP model doesn't have support for distro_boot quite yet, add
a dummy definition for now, to be replaced with the real thing later.
