ffa6602905 arm:pdu001: Use pseudo partition UUID for LINUX kernel boot paramter root
As more and more LINUX drivers are modified to use asynchronous probing
instead of synchronous probing, relying on device names being equal in
U-Boot and LINUX is not possible anymore. This is also true for block
device names like mmc0, mmc1 ect.
With LINUX kernel commit a1a4891 the probing type for the sdhci-omap
driver has been set to asynchronous mode too (probe_type is now
PROBE_PREFER_ASYNCHRONOUS).
In the case of the PDU001 board this results in the devices mmc0 and
mmc1 being swapped between U-Boot and LINUX. Device mmc0 in U-Boot
becomes mmc1 in LINUX an vice versa. Hence using device name identifiers
with LINUX kernel parameter root does not work anymore.
This patch changes the LINUX kernel boot parameter root to use the
pseudo (since we use MBR not GPT) partition UUID to locate the partition
hosting the root file system.

ba90472769 configs: am65x_evm: Define the maximum file size for DFU
In include/dfu.h, if CONFIG_SYS_DFU_MAX_FILE_SIZE is not defined then it is
defined as CONFIG_SYS_DFU_DATA_BUF_SIZE. This is 128 KiB for a53 core and
20 KiB for r5 core. If a larger file is transferred using dfu then it
fails.

CONFIG_SYS_DFU_DATA_BUF_SIZE can not be increased as there is not enough
heap memory to be allocated for the buffer in case of R5 spl.

Fix this by defining CONFIG_SYS_DFU_MAX_FILE_SIZE as the default
CONFIG_SYS_DFU_DATA_BUF_SIZE value.

0e4d5db4e0 sunxi: Add arm64 FEL support
So far we did not support the BootROM based FEL USB debug mode on the
64-bit builds for Allwinner SoCs: The BootROM is using AArch32, but the
SPL runs in AArch64.
Returning back to AArch32 was not working as expected, since the RMR
reset into 32-bit mode always starts execution in the BootROM, but not
in the FEL routine.

After some debug and research and with help via IRC, the CPU hotplug
mechanism emerged as a solution: If a certain R_CPUCFG register contains
some magic, the BootROM will immediately branch to an address stored in
some other register. This works well for our purposes.

Enable the FEL feature by providing early AArch32 code to first save the
FEL state, *before* initially entering AArch64.
If we eventually determine that we should return to FEL, we reset back
into AArch32, and use the CPU hotplug mechanism to run some small
AArch32 code snippet that restores the initially saved FEL state.

That allows the normal AArch64 SPL build to be loaded via the sunxi-fel
tool, with it returning into FEL mode, so that other payloads can be
transferred via FEL as well.

Tested on A64, H5 and H6.

6d295099cc tools: mkimage: Add Allwinner eGON support
So far we used the separate mksunxiboot tool for generating a bootable
image for Allwinner SPLs, probably just for historical reasons.

Use the mkimage framework to generate a so called eGON image the
Allwinner BROM expects.
The new image type is called "sunxi_egon", to differentiate it
from the (still to be implemented) secure boot TOC0 image.

We could perhaps rename U_BOOT_DRIVER() to DM_DRIVER(), but this macro

20e442ab2d dm: Rename U_BOOT_DEVICE() to U_BOOT_DRVINFO()
The current macro is a misnomer since it does not declare a device
directly. Instead, it declares driver_info record which U-Boot uses at
runtime to create a device.

The distinction seems somewhat minor most of the time, but is becomes
quite confusing when we actually want to declare a device, with
of-platdata. We are left trying to distinguish between a device which
isn't actually device, and a device that is (perhaps an 'instance'?)

It seems better to rename this macro to describe what it actually is. The
macros is not widely used, since boards should use devicetree to declare
devices.

Rename it to U_BOOT_DRVINFO(), which indicates clearly that this is
declaring a new driver_info record, not a device.

04be98bd6b efi: capsule: Add support for uefi capsule authentication
Add support for authenticating uefi capsules. Most of the signature
verification functionality is shared with the uefi secure boot
feature.

The root certificate containing the public key used for the signature
verification is stored as part of the device tree blob. The root
certificate is stored as an efi signature list(esl) file -- this file
contains the x509 certificate which is the root certificate.

The efi_sigstore_parse_sigdb function reads the uefi authenticated
variable, stored in the signature database format and builds the
signature store structure. Factor out the code for building
the signature store. This can then be used by the capsule
authentication routine to build the signature store even when the
signature database is not stored as an uefi authenticated variable

A recent change to unify the flattree/livetree code introduced a small
size increase in SPL on some boards. For example SPL code size for
px30-core-ctouch2-px30 increased by 40 bytes.

To address this we can take advantage of the fact that some of the ofnode
functions are only called a few times in SPL, so it is worth inlining
them.

Add new Kconfig options to control this. These functions are not inlined
for U-Boot proper, since this increases code size.

cd53e5bf4b dm: core: Add a new sequence number for devices
At present each device has two sequence numbers, with 'req_seq' being
set up at bind time and 'seq' at probe time. The idea is that devices
can 'request' a sequence number and then the conflicts are resolved when
the device is probed.

This makes things complicated in a few cases, since we don't really know
what the sequence number will end up being. We want to honour the
bind-time requests if at all possible, but in fact the only source of
these at present is the devicetree aliases. Since we have the devicetree
available at bind time, we may as well just use it, in the hope that the
required processing will turn out to be useful later (i.e. the device
actually gets used).

Add a new 'sqq' member, the bind-time sequence number. It operates in
parallel to the old values for now. All devices get a valid sqq value,
i.e. it is never -1.

Drop an #ifdef while we are here.

0b2fa98aa5 linker_lists: Fix alignment issue
The linker script uses alphabetic sorting to group the different linker
lists together. Each group has its own struct and potentially its own
alignment. But when the linker packs the structs together it cannot ensure
that a linker list starts on the expected alignment boundary.

For example, if the first list has a struct size of 8 and we place 3 of
them in the image, that means that the next struct will start at offset
0x18 from the start of the linker_list section. If the next struct has
a size of 16 then it will start at an 8-byte aligned offset, but not a
16-byte aligned offset.

With sandbox on x86_64, a reference to a linker list item using
ll_entry_get() can force alignment of that particular linker_list item,
if it is in the same file as the linker_list item is declared.

Consider this example, where struct driver is 0x80 bytes:

	ll_entry_declare(struct driver, fred, driver)

...

	void *p = ll_entry_get(struct driver, fred, driver)

If these two lines of code are in the same file, then the entry is forced
to be aligned at the 'struct driver' alignment, which is 16 bytes. If the
second line of code is in a different file, then no action is taken, since
the compiler cannot update the alignment of the linker_list item.

In the first case, an 8-byte 'fill' region is added:

 .u_boot_list_2_driver_2_testbus_drv
                0x0000000000270018       0x80 test/built-in.o
                0x0000000000270018                _u_boot_list_2_driver_2_testbus_drv
 .u_boot_list_2_driver_2_testfdt1_drv
                0x0000000000270098       0x80 test/built-in.o
                0x0000000000270098                _u_boot_list_2_driver_2_testfdt1_drv
 *fill*         0x0000000000270118        0x8
 .u_boot_list_2_driver_2_testfdt_drv
                0x0000000000270120       0x80 test/built-in.o
                0x0000000000270120                _u_boot_list_2_driver_2_testfdt_drv
 .u_boot_list_2_driver_2_testprobe_drv
                0x00000000002701a0       0x80 test/built-in.o
                0x00000000002701a0                _u_boot_list_2_driver_2_testprobe_drv

With this, the linker_list no-longer works since items after testfdt1_drv
are not at the expected address.

Ideally we would have a way to tell gcc not to align structs in this way.
It is not clear how we could do this, and in any case it would require us
to adjust every struct used by the linker_list feature.

One possible fix is to force each separate linker_list to start on the
largest possible boundary that can be required by the compiler. However
that does not seem to work on x86_64, which uses 16-byte alignment in this
case but needs 32-byte alignment.

So add a Kconfig option to handle this. Set the default value to 4 so
as to avoid changing platforms that don't need it.

Update the ll_entry_start() accordingly.

41575d8e4c dm: treewide: Rename auto_alloc_size members to be shorter
This construct is quite long-winded. In earlier days it made some sense
since auto-allocation was a strange concept. But with driver model now
used pretty universally, we can shorten this to 'auto'. This reduces
verbosity and makes it easier to read.

Coincidentally it also ensures that every declaration is on one line,
thus making dtoc's job easier.
