fae6c54d23 bootstd: make it possible to use tftp for netboot with standardboot
Add the option to load the bootscript with the tftp command (static IP)
instead of the dhcp command (dynamic IP). For this a new function
tftpb_run similar to dhcp_run, is needed. The selection of which command
to use can be done with the ip_dyn environment variable, which can be
set to yes or no. The ip_dyn variable was chosen as it is already in use
on the imx platforms.
Also edit the bootstd doc.

6a56d10fdc boot: Run the EFI bootmgr just before network devices
At present the EFI bootmgr scans all devices in the system before
deciding which one to boot. Ideally it would use the bootstd iterator
for this, but in the meantime, give it a lower priority, so it runs
just before the network devices.

Note that if there are no hunted network devices hunted, then it will
run at the end, after all bootdevs are exhausted. In other words, it
will always run.

060ce66b83 boot: Run global bootmeths after all bootdevs are exhausted
When there are no more bootdevs we should still go through the global
bootmeths, since some may not have yet been used, if their priority has
not yet come up.

Add a final check for this at the end of the iterator.

eff1dca963 boot: Don't change the method count after global bootmeths
At present before scanning global bootmeths, the iterator sets the

8e31093dbc boot: Support rescanning the global bootmeths

Use a new bootmeth_glob_allowed() function to check if a bootmeth is

For now this has no actual effect, since the global bootmeths are
unconditionally processed at the start, with iter->methods_done being

unprocessed global bootmeths will be found.

0fe6de0dc5 boot: Add a flag for whether there are global bootmeths
The current 'doing_global' refers to being in the state of processing
global bootmeths. Since global bootmeths are currently used once at the
start, it becomes false once the last global bootmeth has been used.

In preparation for allowing bootmeths to run at other points in the
bootstd interation, add a new 'have_global' flag which tracks whether
there are any global bootmeths in the method_order[] list. It is set up
when iteration starts. Unlike doing_global which resets back to false
after the global bootmeths have been handled, once have_global is set to
true, it remains true for the entire iteration process. This provides a
quick check as to whether global-bootmeth processing is needed.

d6277523e5 bootstd: rauc: no valid slot fallback: fix info msg to reflect real flow
If there is no more active slot found in find_active_slot(), like when
all slots in BOOT_ORDER have a count of 0, the counters are reset to their
default value CONFIG_BOOTMETH_RAUC_DEFAULT_TRIES. The BOOT_ORDER is _not_
changed, which is logically correct (especially for the case when there is
only one (active) slot set, e.g. BOOT_ORDER only contains 'B', probably due
to RAUC option prevent-late-fallback being set). Resetting the counters of
inactive slots also does not harm here, and is fine as a generic solution.

But the log_info statement in this scenario
  INFO: Resetting boot order and all slot tries
is incorrect. Change this to
  INFO: Resetting all slot tries to 3
with the 3 being inserted by CONFIG_BOOTMETH_RAUC_DEFAULT_TRIES.

072264c4b3 Revert "fdt: Make sure there is no stale initrd left"
This reverts commit 9fe2e4b464.

Commit 9fe2e4b464 ("fdt: Make sure there is no stale initrd left")
introduces a regression in case when U-Boot transfers control to an EFI
app which acts as a subsequent bootloading program. Such an app might
try to set "linux,initrd-start" and "linux,initrd-end" fdt properties,
but by that time those properties are already removed by the code added
in the mentioned commit.

Particularly, the issue was observed on the E850-96 board where GBL EFI
app [1] can't run Android successfully anymore. More specifically, the
kernel can't see the ramdisk and panics with next messages:

    /dev/root: Can't open blockdev
    VFS: Cannot open root device "" or unknown-block(0,0): error -6
    Please append a correct "root=" boot option; ...
    Kernel panic - not syncing: VFS: Unable to mount root fs on
    unknown-block(0,0)

fdt_initrd() function (where initrd dts properties are removed) is
called two times:

1. First it's called by EFI boot manager (e.g. as a part of U-Boot
Standard Boot mechanism) when it's installing FDT:

    fdt_initrd
    image_setup_libfdt
    efi_install_fdt
    efi_bootmgr_run
    efi_mgr_boot

It's already enough for EFI app to malfunction. But then it's also
called second time:

2. From the EFI app, via EFI DT fixup protocol:

    fdt_initrd
    image_setup_libfdt
    efi_dt_fixup
    struct efi_dt_fixup_protocol efi_dt_fixup_prot = {
        .fixup = efi_dt_fixup
    };

See [2] for specific GBL code which sets those fdt properties and then
runs DT fixup protocol callback.

This issue was discussed [3], but no action was taken since then. Revert
this patch for now, until a proper solution can be found.

5289b6e554 android: boot: fix wrong end of header in v3/v4 parsing
The android boot header is page aligned but the current code made the
assumption that the header was always smaller than the current header
format.

When the page_size is defined as 2048, as this is the case with the

middle of it as the v3 and v4 headers are respectively 2112 and 2128
bytes long.

Additionally, considering that Toradex Verdin-AM62P hardware lifetime

up to 125°C), this series implements necessary changes within TI K3 AM62P and

b40d7b8f72 Merge patch series "lmb: use a single API for all allocations"
Sughosh Ganu <sughosh.ganu@linaro.org> says:

The LMB module has a bunch for API's which are used for allocating
memory. There are a couple of API's for requesting memory, and two
more for reserving regions of memory. Replace these different API's
with a single one, lmb_alloc_mem(). The type of allocation to be made
is specified through one of the parameters to the function.

Additionally, the two API's for reserving regions of memory,
lmb_reserve() and lmb_alloc_addr() are the same with one
difference. One can reserve any memory region with lmb_reserve(),
while lmb_alloc_addr() actually checks that the memory region being
requested is part of the LMB memory map. Reserving memory that is not
part of the LMB memory map is pretty futile -- the allocation
functions do not allocate memory which has not been added to the LMB
memory map.

This series also removes the functionality allowing for reserving
memory regions outside the LMB memory map. Any request for reserving a
region of memory outside the LMB memory map now returns an -EINVAL
error.

Certain places in the common code using the LMB API's were not
checking the return value of the functions. Checks have been added for
them. There are some calls being made from the architecture/platform
specific code which too do not check the return value. Those have been
kept the same, as I do not have the platform with me to check if it
causes any issues on those platforms.

In addition, there is a patch which refactors code in
lmb_overlaps_region() and lmb_can_reserve_region() so that both
functionalities can be put in a single function, lmb_overlap_checks().

Finally, a new patch has been added which checks the return value of
the lmb allocation function before copying the device-tree to the
allocated address.

745f981f70 lmb: use a single function to free up memory
There is no need to have two separate API's for freeing up memory. Use
a single API lmb_free() to achieve this.

6e4675b8e5 lmb: replace the lmb_alloc() and lmb_alloc_base() API's
There currently are two API's for requesting memory from the LMB
module, lmb_alloc() and lmb_alloc_base(). The function which does the
actual allocation is the same. Use the earlier introduced API
lmb_alloc_mem() for both types of allocation requests.

9d37a3d6e8 lmb: replace lmb_reserve() and lmb_alloc_addr() API's
There currently are multiple allocation API's in the LMB module. There
are a couple of API's for allocating memory(lmb_alloc() and
lmb_alloc_base()), and then there are two for requesting a reservation
for a particular memory region (lmb_reserve() and
lmb_alloc_addr()). Introduce a single API lmb_alloc_mem() which will
cater to all types of allocation requests and replace lmb_reserve()
and lmb_alloc_addr() with the new API.

Moreover, the lmb_reserve() API is pretty similar to the
lmb_alloc_addr() API, with the one difference being that the
lmb_reserve() API allows for reserving any address passed to it --
the address need not be part of the LMB memory map. The
lmb_alloc_addr() does check that the address being requested is
actually part of the LMB memory map.

There is no need to support reserving memory regions which are outside
the LMB memory map. Remove the lmb_reserve() API functionality and use
the functionality provided by lmb_alloc_addr() instead. The
lmb_alloc_addr() will check if the requested address is part of the
LMB memory map and return an error if not.

e122850933 boot/image-android: Workaround kernel/ramdisk invalid addr
Some androidboot image have invalid kernel/ramdisk load addr,
force to ignore those value and use loadaddr instead.

There is a concern on exposing the whole memory to image loading is
dangerous. Also, since it's not always possible to change the load
addr by repacking the boot.img (mainly due to AVB signature mismatch),
we need a way to use kernel_addr_r and ramdisk_addr_r.
