8cfac237b9 Merge branch '2022-04-25-initial-implementation-of-stdboot'
To quote the author:
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:

a57ad20d07 efi_loader: split efi_init_obj_list() into two stages
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.

bdaeea1b68 malloc: Annotate allocator for valgrind
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

4de720e98d Merge branch 'master' of https://source.denx.de/u-boot/custodians/u-boot-sunxi
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
fixes for that later.
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).

12a3e1ada0 arm: init: save previous bootloader data
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

8e1c9fe243 spl: Add semihosting boot method
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.

96991e652f console: usb: kbd: Limit poll frequency to improve performance
Using the XHCI driver, the function `usb_kbd_poll_for_event` takes
30-40ms to run. The exact time is dependent on the polling interval the
keyboard requests in its descriptor, and likely cannot be significantly
reduced without major rework to the XHCI driver.

The U-Boot EFI console service sets a timer to poll the keyboard every 5
microseconds, and this timer is checked every time a block is read off
disk. The net effect is that, on my system, loading a ~40MiB kernel and
initrd takes about 62 seconds with a slower keyboard and 53 seconds
with a faster one, with the vast majority of the time spent polling the
keyboard.

To solve this problem, this patch adds a 20ms delay between consecutive
calls to `usb_kbd_poll_for_event`. This is sufficient to reduce the
total loading time to under half a second for both keyboards, and does

ce3e75dc59 bloblist: Update to use conditional value
Use the new IF_ENABLED_INT() feature to avoid needing our own inline
function to handle this case. Tidy up the logic to ensure that the value
is only used when present. Update the 'expected' comment also.

c1335e2ca5 spl: ymodem: Fix buffer overflow during Image copy
ymodem_read_fit() driver will end copying up to BUF_SIZE boundary even
when requested size of copy operation is less than that.
For example, if offset = 0, size = 1440B, ymodem_read_fit() ends up
copying 2KB from offset = 0, to destination buffer addr

This causes data corruption when malloc'd buffer is passed during UART
boot since commit 03f1f78a9b ("spl: fit: Prefer a malloc()'d buffer
for loading images")

With this, UART boot works again on K3 (AM654, J7, AM64) family of
devices.

Fixes: 03f1f78a9b ("spl: fit: Prefer a malloc()'d buffer for loading images")

c592292385 spl: add support for custom boot method names
Currently the names MMC1, MMC2 and MMC2_2 are output in the SPL. To
achieve more userbility here the name of the boot source can be returned.
E.g. for "MMC1" -> "eMMC" or "MMC2" -> "SD card".

fc2b399ac0 usb: gadget: Add CDC ACM function
Add support for CDC ACM using the new UDC and gadget API. This protocol
can be used for serial over USB data transfer and is widely supported
by various OS (GNU/Linux, MS-Windows, OSX...). The usual purpose of
such link is to access device debug console and can be useful for
products not exposing regular UART to the user.

A default stdio device named 'usbacm' is created, and can be used
to redirect console to USB link over CDC ACM:

> setenv stdin usbacm; setenv stdout usbacm

99f844ba3a tools: Pass the key blob around
At present we rely on the key blob being in the global_data fdt_blob
pointer. This is true in U-Boot but not with tools. For clarity, pass the
parameter around.
