It is sometimes useful to process all children, making sure they are
probed first. Add functions to help with this and a macro to make it more
convenient.

When generating ACPI tables we need to make sure that all devices have
read their platform data, so that they can generate the tables correctly.
Rather than adding this code in ACPI, create a core function to handle it.

Add a new function to read a property that supports reading the length as
well.
Reimplement ofnode_read_string() using it and fix its comment.

This function is actually intended to read a string rather than a
property. All of its current callers use it that way. Also there is no way
to return the length of the property from this function.
Rename it to better indicate its purpose, using ofnode_read as the prefix
since this matches most other functions.
Also add some tests which are missing for these functions.

The current comment is a big vague and misleading. Rewrite it to state
precisely what the function does.

If a test happens to use the same variable as the macro parameter the
macro does not work as intended. Add an underscore to guard against this.

These functions do not modify the device so should use a const pointer to

Changes:
- use boot.img instead of boot_fit.img
- use .dtb from boot.img v2
- implement recovery boot
- always boot ramdisk from boot.img, we can't mount system as root
now, as system is a logical partition inside of super partition
- don't add "skip_initramfs" to cmdline anymore
- to boot into recovery, use boot image from recovery partition
- prepare partition table:
- A/B scheme
- use 'super' partition instead of 'system' and 'vendor'
- add dtbo partitions
- introduce metadata partition
Not implemented: reading and applying dtbo blobs from dtbo partition.

Android Boot Image v1 adds "Recovery DTB" field in image header and
associate payload in boot image itself [1]. Payload should be in
Android DTB/DTBO format [2]. That "Recovery DTB" area should be only
populated for non-A/B devices, and only in recovery image.
Add function to get an address and size of that payload. That function
can be further used e.g. in 'abootimg' command to provide the user a way
to get the address of recovery dtbo from U-Boot shell, which can be
further parsed using 'adtimg' command.

Android Boot Image v2 adds "DTB" payload (and corresponding field in the
image header). Provide functions for its handling:
- android_image_get_dtb_by_index(): Obtain DTB blob from "DTB" part of
boot image, by blob's index
- android_image_print_dtb_contents(): Iterate over all DTB blobs in
"DTB" part of boot image and print those blobs info
"DTB" payload might be in one of the following formats:
1. concatenated DTB blobs
2. Android DTBO format
The latter requires "android-image-dt.c" functionality, so this commit
selects that file for building for CONFIG_ANDROID_BOOT_IMAGE option.
Right now this new functionality isn't used, but it can be used further.
As it's required to apply some specific dtbo blob(s) from "dtbo"
partition, we can't automate this process inside of "bootm" command. But
we can do next:
- come up with some new command like "abootimg" to extract dtb blob
from boot image (using functions from this patch)
- extract desired dtbo blobs from "dtbo" partition using "adtimg"
command
- merge dtbo blobs into dtb blob using "fdt apply" command
- pass resulting dtb blob into bootm command in order to boot the
Android kernel with Android ramdisk from boot image

or SYS_NS16550_PORT_MAPPED in U-Boot.

Slim Bootloader serial driver leverages NS16550_DYNAMIC.

At present this driver uses an assortment of CONFIG options to control
how it accesses the hardware. This is painful for platforms that are
supposed to be controlled by a device tree or a previous-stage bootloader.
Add a new CONFIG option to enable fully dynamic configuration. This
controls register spacing, size, offset and endianness.

UniPhier SoC updates for v2020.04 (2nd)
Denali NAND driver changes:
- Set up more registers in denali-spl for SOCFPGA
- Make clocks optional
- Do not assert reset signals in the remove hook
- associate SPARE_AREA_SKIP_BYTES with DT compatible
- switch to UCLASS_MTD
UniPhier platform changes:
- fix a bug in dram_init()
- specify loadaddr for "source" command
|
|
If the "source" command is not given the address, it uses
CONFIG_SYS_LOAD_ADDR, which is compile-time determined.
Using the "loadaddr" environment variable is handier because it is
relocated according to the memory base when CONFIG_POSITION_INDEPENDENT
is enabled.

All rockchip platforms support TPL or SPL-based bootloader
in mainline with U-Boot proper as final stage. For each
stage we need to burn the image on to flash with respective
offsets.
This patch creates a single boot image component using
- binman, for arm32 rockchip platforms
- pad_cat, for arm64 rockchip platforms.
This would help users to get rid of burning different
boot stage images.
The new image called 'u-boot-rockchip.bin'
which can burn into flash like:
₹ sudo dd if=u-boot-rockchip.bin of=/dev/sda seek=64
This would support all rockchip platforms, except rk3128
since it doesn't support for SPL yet.

this would help to support redundent boot.
Once the redundant boot triggers, the altboot command

bootable partition which supposed to be a recovery
partition where redundant boot required.
