[PATCH v3 00/21] Universal Payload initial series

Universal Payload (UPL) is an Industry Standard for firmware components[1]. UPL is designed to improve interoperability within the firmware industry, allowing mixing and matching of projects with less friction and fewer project-specific implementations. UPL is cross-platform, supporting ARM, x86 and RISC-V initially. This series provides some initial support for this, targeting 0.9.1 and sandbox only. Features still to come include: - Support for architectures - FIT validation - Handoff validation - Interoperability tests This series is available at dm/uplb-working and requires the alist series at dm/alist-working[2] [1] https://universalpayload.github.io/spec/ [2] https://patchwork.ozlabs.org/project/uboot/list/?series=414642 Changes in v3: - Use longer error messages - Use -errno instead of inventing a new error - Use sizeof(*header) instead of 512 - Use a block size of 1 if !CONFIG_SPL_LOAD_BLOCK - Fix 'handed' typo - Rebase on earlier change - Allow up.h to be built by the host build - Split out into its own commit Changes in v2: - Put the upl tests under their own subcommand to avoid bootstd init - Add a function to init the UPL process in SPL - Hang when something goes wrong, to avoid a broken boot - Add a runtime flag to enable UPL - Put upl_image() calls in a common place - Add a link to the spec - Add a link to the command - Support CI testing - Rework to use alist instead of fixed-length arrays Simon Glass (21): sandbox: Use const in os_jump_to_file() sandbox: Fix a comment in os_find_u_boot() test: Move some SPL-loading test-code into sandbox common fdt: Don't overwrite bloblist devicetree sandbox: fdt: Avoid overwriting an existing fdt sandbox: Return error code from read/write/seek sandbox: Add ELF file to VPL u-boot.img sandbox: Set up global_data earlier upl: Add support for reading a upl handoff upl: Add support for writing a upl handoff upl: Add basic tests upl: Add a command upl: Add support for Universal Payload in SPL spl: Set SPL_FIT_FOUND for full FIT also spl: Plumb in the Universal Payload handoff upl: Plumb in universal payload to the init process sandbox_vpl: Enable Universal Payload upl: Add initial documentation sandbox: Add a flag to enable UPL sandbox: Add an SPL loader for UPL upl: Add an end-to-end test MAINTAINERS | 13 + Makefile | 4 +- arch/sandbox/cpu/cpu.c | 2 + arch/sandbox/cpu/os.c | 30 +- arch/sandbox/cpu/spl.c | 120 +++++- arch/sandbox/cpu/start.c | 18 +- arch/sandbox/include/asm/spl.h | 15 + arch/sandbox/include/asm/state.h | 1 + boot/Kconfig | 70 ++++ boot/Makefile | 4 + boot/image-fit.c | 4 + boot/upl_common.c | 60 +++ boot/upl_common.h | 24 ++ boot/upl_read.c | 588 ++++++++++++++++++++++++++++ boot/upl_write.c | 622 ++++++++++++++++++++++++++++++ cmd/Kconfig | 7 + cmd/Makefile | 1 + cmd/upl.c | 118 ++++++ common/board_f.c | 22 ++ common/board_r.c | 2 + common/spl/Makefile | 2 + common/spl/spl.c | 8 + common/spl/spl_fit.c | 10 + common/spl/spl_upl.c | 171 ++++++++ configs/sandbox_defconfig | 1 + configs/sandbox_vpl_defconfig | 4 + doc/usage/cmd/upl.rst | 186 +++++++++ doc/usage/index.rst | 2 + doc/usage/upl.rst | 46 +++ drivers/block/sandbox.c | 4 +- drivers/usb/emul/sandbox_flash.c | 2 +- fs/sandbox/sandboxfs.c | 6 +- include/asm-generic/global_data.h | 19 + include/os.h | 6 +- include/spl.h | 16 + include/test/suites.h | 1 + include/upl.h | 364 +++++++++++++++++ lib/fdtdec.c | 1 + test/boot/Makefile | 2 + test/boot/upl.c | 437 +++++++++++++++++++++ test/cmd_ut.c | 3 + test/image/spl_load_os.c | 53 +-- test/py/tests/test_upl.py | 38 ++ 43 files changed, 3035 insertions(+), 72 deletions(-) create mode 100644 boot/upl_common.c create mode 100644 boot/upl_common.h create mode 100644 boot/upl_read.c create mode 100644 boot/upl_write.c create mode 100644 cmd/upl.c create mode 100644 common/spl/spl_upl.c create mode 100644 doc/usage/cmd/upl.rst create mode 100644 doc/usage/upl.rst create mode 100644 include/upl.h create mode 100644 test/boot/upl.c create mode 100644 test/py/tests/test_upl.py -- 2.34.1

[PATCH v5 0/4] alist: Implement a pointer list / array of structs
by Simon Glass 07 Aug '24

07 Aug '24

This data structure provides a list of pointers / array of structures. I was planning to use it for the lmb restructure, to allow it to support any number of entries, but then I gave up on it. There are quite a few places in U-Boot where such a list would be useful, since it supports growing the array. The series includes a patch to convert an existing function to use this. It adds a little under 300 bytes of code with Thumb2. With this version, use of realloc() is option and off by default. This reduces the size growth on xilinx_versal_mini_emmc0 (aarch64) from 1765 bytes to 636, for the str_to_list() patch. The str_to_list() patch is marked as RFC since I beleive we have decided not to apply it. Example: struct my_struct obj; struct my_struct *ptr = alist_add(&lst, &obj, struct my_struct); // now ptr is in the list [1] https://patchwork.ozlabs.org/project/uboot/list/?series=371258&state=* Changes in v5: - Drop use of realloc() altogether, since the benefit is small - Add alist_add_placeholder() - Drop type argument for alist_add() Changes in v4: - Avoid using realloc() unless specifically enabled by Kconfig Changes in v3: - Add prototype for alist_expand_by() - Update for alist_add() API change Changes in v2: - Fix 'typeee' typo - Make alist_get_ptr() take a const alist * - Make alist_add() take a struct rather than a pointer - Declare alist_expand_by() as static Simon Glass (4): malloc: Support testing with realloc() lib: Handle a special case with str_to_list() alist: Add support for an allocated pointer list RFC: lib: Convert str_to_list() to use alist common/dlmalloc.c | 4 + include/alist.h | 228 +++++++++++++++++++++++++++++++++++++++++++ lib/Makefile | 1 + lib/alist.c | 158 ++++++++++++++++++++++++++++++ lib/strto.c | 33 ++++--- test/lib/Makefile | 1 + test/lib/alist.c | 242 ++++++++++++++++++++++++++++++++++++++++++++++ test/str_ut.c | 4 +- 8 files changed, 654 insertions(+), 17 deletions(-) create mode 100644 include/alist.h create mode 100644 lib/alist.c create mode 100644 test/lib/alist.c -- 2.34.1

[PATCH] remoteproc: uclass: Modify uc_pdata->name to use combination of device name and device's parent name
by MD Danish Anwar 07 Aug '24

07 Aug '24

uc_pdata->name is populated from device tree property "remoteproc-name". For those devcices that don't set "remoteproc-name", uc_pdata->name falls back to dev->name. If two devices have same name, this will result into uc_pdata->name not being unique and rproc_init() will fail. Fix this by using combination of dev->name and dev->parent->name instead of using just the dev->name to populate uc_pdata->name. Signed-off-by: MD Danish Anwar <danishanwar(a)ti.com> --- Cc: Andrew Davis <afd(a)ti.com> Failure Example: In k3-am64-main.dtsi, both pru0_0 [1] and pru1_0 [2] will have dev->name as "pru@34000" although their parent name is different. pru0_0 has dev->name as "pru@34000" and parent name as "icssg@30000000" pru1_0 has dev->name as "pru@34000" and parent name as "icssg@30080000" rproc_init() fails for pru1_0 as the the uc_pdata->name becomes same as the pru0_0.

[PATCH 00/14] event: Replace some more init hooks
by Simon Glass 07 Aug '24

07 Aug '24

This series replaces some more of the init hooks in board_f.c and board_r.c with events. Notably it converts last_state_init() over. It also provides a 'simple' event spy, which takes no arguments. It turns out that this is quite a common case, so it is worth optimising for this, to reduce code size, before events become too commonly used. Finally, it introduces a way of emitting an event in an initcall, instead of calling a function. This is likely to be used at least as often as the functions, as we convert more of these initcalls. As part of this, the initcall code is brought back into a C file. Somehow the compiler has changed or something else, so that this does not confer any benefits now. For boards with EVENT enabled, this unfortunately results in small growth, e.g. for firefly: aarch64: (for 1/1 boards) all +114.0 data +16.0 rodata +22.0 text +76.0 arm: (for 1/1 boards) all +82.0 rodata +18.0 text +64.0 For boards without EVENT enabled the growth is smaller, e.g. nokia_rx51: arm: (for 1/1 boards) all +32.0 data +8.0 rodata -8.0 text +32.0 I cannot find a good way to avoid the latter, other than macro magic with an embedded comma (to completely remove an event entry), which seems nasty.
