e0d1a1ea68 efi_loader: add return to efibootmgr event group
When the image loaded by efibootmgr returns, efibootmgr
needs to clean the resources. Adding the event of returning
to efibootmgr is useful to simplify the implementation.

e23c8e81eb efi_loader: add missing const classifier for event service
const classifier is missing in EventGroup parameter of
CreateEventEx(). Fix it to remove the compiler warning.

NotifyContext parameter of CreateEventEx() is also defined
with const in UEFI specification, but NotifyContext parameter
of CreateEvent() is defined without const.
Since current implementation calls the common efi_create_event()
function from both CreateEventEx() and CreateEvent() services,
NotifyContext parameter leaves as is.

550862bc12 efi_loader: Boot var automatic management
Changes for complying to EFI spec §3.5.1.1
'Removable Media Boot Behavior'.
Boot variables can be automatically generated during a removable
media is probed. At the same time, unused boot variables will be
detected and removed.

Please note that currently the function 'efi_disk_remove' has no
ability to distinguish below two scenarios
a) Unplugging of a removable media under U-Boot
b) U-Boot exiting and booting an OS
Thus currently the boot variables management is not added into
'efi_disk_remove' to avoid boot options being added/erased
repeatedly under scenario b) during power cycles
See TODO comments under function 'efi_disk_remove' for more details

The original efi_secboot tests expect that BootOrder EFI variable
is not defined. With this commit, the BootOrder EFI variable is
automatically added when the disk is detected. The original
efi_secboot tests end up with unexpected failure.
The efi_secboot tests need to be modified to explicitly set
the BootOrder EFI variable.

squashfs and erofs ls tests are also affected by this modification,
need to clear the previous state before squashfs ls test starts.

6d6ea52b62 fs: btrfs: fix reading when length specified
The btrfs read function limits the read length to ensure that it
and the read offset do not together exceed the size of the file.
However, this size was only being queried if the read length was
passed a value of zero (meaning "whole file"), and the size is
defaulted to 0 otherwise. This means the clamp will just zero out
the length if one is specified, preventing reading of the file.

Fix this by checking the file size unconditionally, and unifying
the default length and clamping logic as a single range check instead.

This bug was discovered when trying to boot Linux with initrd= via
'bootefi' from a btrfs partition. The EFI stub entered an infinite
loop of zero-length reads while trying to read the initrd, and the
boot process stalled indefinitely.

6c1608b1ff Merge patch series "spl: Use common function for loading/parsing images"
To quote the author:

This series adds support for loading all image types (Legacy (with and without
LZMA), FIT (with and without LOAD_FIT_FULL), and i.MX) to the MMC, SPI, NOR,
NET, FAT, EXT, NVMe, and semihosting load methods. It does this by introducing a
helper function which handles the minutiae of invoking the proper parsing
function, and reading the rest of the image.

Hopefully, this will make it easier for load methods to support all image types
that U-Boot supports, without having undocumented unsupported image types. I
applied this to several loaders which were invoking spl_load_simple_fit and/or
spl_parse_image_header, but I did not use it with others (e.g. DFU/RAM) which
had complications in the mix.

This series is organized roughly into two parts. Patches up to "spl: Add generic
spl_load function" are all setup or size-reduction oriented. Later patches
generally convert various load functions to spl_load.

bloat-o-meter results (for CONFIG_SPL only) at [1]. Size growth has been the
bigegst challenge to preparing this series. I have used every trick I can think
of to reduce bloat. Some SAMA boards no longer fit, but I have a plan to fix
them [2].

This is bar far the largest and most-difficult revision of this series to-date.
There are probably still things which can reduce the size, but I have been
working on this series for the better part of two months and I think it is a
good idea to get some feedback. Because of the SAMA bloat, this series will not
pass CI, so I expect to do a v7 before this is ready to apply. Feel free,
however, to apply patches in the first half (especially the fixes).

This version of the series is better-tested than ever before, thanks to some new
unit tests. However, things like the i.MX ROMAPI are untested. NAND should also
be tested more-widely, for reasons listed in the commit message. I encourage you
try this series out on your favorite board.

11f834614e spl: Convert nand to spl_load
This converts the nand load method to use spl_load. nand_page_size may not
be valid until after nand_spl_load_image is called (see e.g. fsl_ifc_spl),
so we set bl_len in spl_nand_read. Since spl_load reads the header for us,
we can remove that argument from spl_nand_load_element.

There are two possible regressions which could result from this commit.
First, we ask for a negative address from spl_get_load_buffer. That is,
instead of

	header = spl_get_load_buffer(0, sizeof(*header));

we do

	header = spl_get_load_buffer(-sizeof(*header), sizeof(*header));

this could cause a problem if spl_get_load_buffer does not return valid
memory for negative offsets. Second, we now set bl_len for legacy images.
This can cause memory up to a bl_len - 1 before the image load address to
be written, which might not have been the case before. If this turns out to
be a problem, we can add an option for a bounce buffer.

We can't load FITs with external data with SPL_LOAD_FIT_FULL, so disable the
test in that case. No boards enable SPL_NAND_SUPPORT and SPL_LOAD_FIT_FULL, so
this is not a regression.

a helper config SYS_MMCSD_RAW_MODE. This ensures we can inline spl_load

775074165d spl: Add generic spl_load function
Implementers of SPL_LOAD_IMAGE_METHOD have to correctly determine what
type of image is being loaded and then call the appropriate image load
function correctly. This is tricky, because some image load functions
expect the whole image to already be loaded (CONFIG_SPL_LOAD_FIT_FULL),
some will load the image automatically using spl_load_info.read()
(CONFIG_SPL_LOAD_FIT/CONFIG_SPL_LOAD_IMX_CONTAINER), and some just parse
the header and expect the caller to do the actual loading afterwards
(legacy/raw images). Load methods often only support a subset of the
above methods, meaning that not all image types can be used with all
load methods. Further, the code to invoke these functions is
duplicated between different load functions.

To address this problem, this commit introduces a "spl_load" function.
It aims to handle image detection and correct invocation of each of the
parse/load functions.

Although this function generally results in a size reduction with
several users, it tends to bloat boards with only a single user.
This is generally because programmers open-coding the contents of this
function can make optimizations based on the specific loader. For
example, NOR flash is memory-mapped, so it never bothers calling
load->read. The compiler can't really make these optimizations across
translation units. LTO solves this, but it is only available on some
arches. To address this, perform "pseudo-LTO" by inlining spl_load when
there are one or fewer users. At the moment, there are no users, so
define SPL_LOAD_USERS to be 0.

5271e359a4 spl: Only support bl_len when we have to
Aligning addresses and sizes causes overhead which is unnecessary when we
are not loading from block devices. Remove bl_len when it is not needed.

For example, on iot2050 we save 144 bytes with this patch (once the rest of
this series is applied):

add/remove: 0/0 grow/shrink: 0/3 up/down: 0/-144 (-144)
Function                                     old     new   delta
spl_load_simple_fit                          920     904     -16
load_simple_fit                              496     444     -52
spl_spi_load_image                           384     308     -76
Total: Before=87431, After=87287, chg -0.16%

We use panic() instead of BUILD_BUG_ON in spl_set_bl_len because we still
need to be able to compile it for things like mmc_load_image_raw_sector,
even if that function will not be used.

afdd2d98c2 spl: Remove filename from spl_load_info
For filesystems, filename serves the same purpose as priv. However,
spl_load_fit_image also uses it to determine whether to use a DMA-aligned
buffer. This is beneficial for FAT, which uses a bounce-buffer if the
destination is not DMA-aligned. However, this is unnecessary now that
filesystems set bl_len to ARCH_DMA_MINALIGN instead. With this done, we can
remove filename entirely.

b63664be6a spl: Set FAT bl_len to ARCH_DMA_MINALIGN
Instead of relying on the presence of filename to determine whether we are
dealing with a FAT filesystem (and should DMA-align the buffer), have FAT set
bl_len to ARCH_DMA_MINALIGN instead. With this done, we can remove the
special-case logic checking for the presence of filename.

Because filesystems are not block-based, we may read less than the size passed
to spl_load_info.read. This can happen if the file size is not DMA-aligned. This
is fine as long as we read the amount we originally wanted to. Modify the
conditions for callers of spl_load_info.read to check against the original,
unaligned size to avoid failing spuriously.

73c40fcb73 spl: Refactor spl_load_info->read to use units of bytes
Simplify things a bit for callers of spl_load_info->read by refactoring it
to use units of bytes instead of bl_len. This generally simplifies the
logic, as MMC is the only loader which actually works in sectors. It will
also allow further refactoring to remove the special-case handling of
filename.  spl_load_legacy_img already works in units of bytes (oops) so it
doesn't need to be changed.

similar tricks to avoid divisions.

5e6a112e11 Merge patch series "nand: Add sandbox tests"
To quote the author:

This series tests raw nand flash in sandbox and fixes various bugs discovered in
the process. I've tried to do things in a contemporary manner, avoiding the
(numerous) variations present on only a few boards. The test is pretty minimal.
Future work could test the rest of the nand API as well as the MTD API.

Bloat (for v1) at [1] (for boards with SPL_NAND_SUPPORT enabled). Almost
everything grows by a few bytes due to nand_page_size. A few boards grow more,
mostly those using nand_spl_loaders.c. CI at [2].

reference these fields. This can result in more efficient code. filename
must stay even if it is unused, since load_simple_fit uses it.

517e70856f spl: semihosting: Don't close fd before spl_load_simple_fit
On real hardware, semihosting calls tend to have a large constant
overhead (on the order of tens of milliseconds). Reduce the number of
calls by one by reusing the existing fd in smh_fit_read, and closing it
at the end of spl_smh_load_image.
