[PATCH] lds: align u-boot-nodtb with 8 bytes boundary
by Eugen Hristev 29 Jan '25

29 Jan '25

Newer DTC require that the DTB start address is aligned at 8 bytes. In the u-boot.bin case, the u-boot-nodtb.bin is concatenated with the DTB, but there is no alignment/padding to the next 8byte aligned address. This causes the board to fail booting, because the FDT will claim that the DTB inside u-boot.bin is not a valid DTB, it will fail with -FDT_ERR_ALIGNMENT. To solve this, have the u-boot binary `_end` aligned with 8 bytes. The objcopy in the Makefile will create the u-boot-nodtb.bin and it has to be truncated to 8 bytes to correspond to the u-boot.map file which will have the `_end` aligned to 8 bytes. The lds files which use devicetrees have been changed to align the `_end` tag with 8 bytes. This patch is also a prerequisite to have the possibility to update the dtc inside u-boot to newer versions (1.6.1+) Signed-off-by: Eugen Hristev <eugen.hristev(a)microchip.com> --- Hi, I could not test all affected boards, it's an impossible task. I tried this on at91 boards which I have, and ran the CI on denx. I cannot guarantee that no other boards are affected, so this patch is a bit of an RFC. If the u-boot-nodtb.bin does not have the size equal with the corresponding one in u-boot.map, the binary_size_check will fail at build time with something like this: u-boot.map shows a binary size of 502684 but u-boot-nodtb.bin shows 502688 Thanks, Eugen Makefile | 2 ++ arch/arm/cpu/armv8/u-boot.lds | 4 ++-- arch/arm/cpu/u-boot-spl.lds | 1 + arch/arm/cpu/u-boot.lds | 1 + arch/arm/lib/elf_arm_efi.lds | 5 +++++ arch/arm/mach-at91/arm926ejs/u-boot-spl.lds | 2 +- arch/arm/mach-at91/armv7/u-boot-spl.lds | 2 +- arch/arm/mach-zynq/u-boot-spl.lds | 2 +- arch/mips/cpu/u-boot.lds | 2 +- arch/sandbox/cpu/u-boot.lds | 6 ++++++ arch/sh/cpu/u-boot.lds | 2 ++ board/ti/am335x/u-boot.lds | 1 + tools/binman/test/u_boot_binman_embed.lds | 2 +- 13 files changed, 25 insertions(+), 7 deletions(-) diff --git a/Makefile b/Makefile index 9d84f96481..b4d387bcce 100644 --- a/Makefile +++ b/Makefile @@ -1317,6 +1317,8 @@ endif u-boot-nodtb.bin: u-boot FORCE $(call if_changed,objcopy_uboot) +# Make sure the size is 8 byte-aligned. + @truncate -s %8 $@ $(BOARD_SIZE_CHECK) u-boot.ldr: u-boot diff --git a/arch/arm/cpu/armv8/u-boot.lds b/arch/arm/cpu/armv8/u-boot.lds index 8fe4682dd2..e5fa4ef95c 100644 --- a/arch/arm/cpu/armv8/u-boot.lds +++ b/arch/arm/cpu/armv8/u-boot.lds @@ -145,10 +145,10 @@ SECTIONS *(.__rel_dyn_end) } - _end = .; - . = ALIGN(8); + _end = .; + .bss_start : { KEEP(*(.__bss_start)); } diff --git a/arch/arm/cpu/u-boot-spl.lds b/arch/arm/cpu/u-boot-spl.lds index fb2189d50d..732ed42db1 100644 --- a/arch/arm/cpu/u-boot-spl.lds +++ b/arch/arm/cpu/u-boot-spl.lds @@ -55,6 +55,7 @@ SECTIONS .end : { + . = ALIGN(8); *(.__end) } diff --git a/arch/arm/cpu/u-boot.lds b/arch/arm/cpu/u-boot.lds index f25f72b2e0..274e1a7d30 100644 --- a/arch/arm/cpu/u-boot.lds +++ b/arch/arm/cpu/u-boot.lds @@ -193,6 +193,7 @@ SECTIONS .end : { + . = ALIGN(8); *(.__end) } diff --git a/arch/arm/lib/elf_arm_efi.lds b/arch/arm/lib/elf_arm_efi.lds index 767ebda635..f3867021d3 100644 --- a/arch/arm/lib/elf_arm_efi.lds +++ b/arch/arm/lib/elf_arm_efi.lds @@ -54,6 +54,11 @@ SECTIONS .rel.data : { *(.rel.data) *(.rel.data*) } _data_size = . - _etext; + .end : { + . = ALIGN(8); + *(.__end) + } + /DISCARD/ : { *(.rel.reloc) *(.eh_frame) diff --git a/arch/arm/mach-at91/arm926ejs/u-boot-spl.lds b/arch/arm/mach-at91/arm926ejs/u-boot-spl.lds index 1a8bf94dee..d7e5d81ecc 100644 --- a/arch/arm/mach-at91/arm926ejs/u-boot-spl.lds +++ b/arch/arm/mach-at91/arm926ejs/u-boot-spl.lds @@ -31,7 +31,7 @@ SECTIONS . = ALIGN(4); __u_boot_list : { KEEP(*(SORT(__u_boot_list*))) } > .sram - . = ALIGN(4); + . = ALIGN(8); __image_copy_end = .; .end : diff --git a/arch/arm/mach-at91/armv7/u-boot-spl.lds b/arch/arm/mach-at91/armv7/u-boot-spl.lds index 6ca725fc4c..2a0a1b4b86 100644 --- a/arch/arm/mach-at91/armv7/u-boot-spl.lds +++ b/arch/arm/mach-at91/armv7/u-boot-spl.lds @@ -38,7 +38,7 @@ SECTIONS . = ALIGN(4); __u_boot_list : { KEEP(*(SORT(__u_boot_list*))) } > .sram - . = ALIGN(4); + . = ALIGN(8); __image_copy_end = .; .end : diff --git a/arch/arm/mach-zynq/u-boot-spl.lds b/arch/arm/mach-zynq/u-boot-spl.lds index 8c18d3f91f..c0320dbe1e 100644 --- a/arch/arm/mach-zynq/u-boot-spl.lds +++ b/arch/arm/mach-zynq/u-boot-spl.lds @@ -41,7 +41,7 @@ SECTIONS KEEP(*(SORT(__u_boot_list*))); } > .sram - . = ALIGN(4); + . = ALIGN(8); _image_binary_end = .; diff --git a/arch/mips/cpu/u-boot.lds b/arch/mips/cpu/u-boot.lds index 9a4ebcd151..182e9bc6e5 100644 --- a/arch/mips/cpu/u-boot.lds +++ b/arch/mips/cpu/u-boot.lds @@ -56,7 +56,7 @@ SECTIONS . += CONFIG_MIPS_RELOCATION_TABLE_SIZE - 4; } - . = ALIGN(4); + . = ALIGN(8); _end = .; .bss __rel_start (OVERLAY) : { diff --git a/arch/sandbox/cpu/u-boot.lds b/arch/sandbox/cpu/u-boot.lds index ba8dee50c7..3fbca6d248 100644 --- a/arch/sandbox/cpu/u-boot.lds +++ b/arch/sandbox/cpu/u-boot.lds @@ -51,6 +51,12 @@ SECTIONS *(.dynsym) __dyn_sym_end = .; } + + .end : + { + . = ALIGN(8); + *(.__end) + } } INSERT BEFORE .data; diff --git a/arch/sh/cpu/u-boot.lds b/arch/sh/cpu/u-boot.lds index d360eea7eb..226f50b19c 100644 --- a/arch/sh/cpu/u-boot.lds +++ b/arch/sh/cpu/u-boot.lds @@ -74,6 +74,8 @@ SECTIONS KEEP(*(SORT(__u_boot_list*))); } >ram + . = ALIGN(8); + PROVIDE (__init_end = .); PROVIDE (reloc_dst_end = .); PROVIDE (_end = .); diff --git a/board/ti/am335x/u-boot.lds b/board/ti/am335x/u-boot.lds index 087dee8bb2..deb9098a90 100644 --- a/board/ti/am335x/u-boot.lds +++ b/board/ti/am335x/u-boot.lds @@ -118,6 +118,7 @@ SECTIONS .end : { + . = ALIGN(8); *(.__end) } diff --git a/tools/binman/test/u_boot_binman_embed.lds b/tools/binman/test/u_boot_binman_embed.lds index e213fa8a84..93c0ae6aed 100644 --- a/tools/binman/test/u_boot_binman_embed.lds +++ b/tools/binman/test/u_boot_binman_embed.lds @@ -18,7 +18,7 @@ SECTIONS *(.text*) } - . = ALIGN(4); + . = ALIGN(8); .data : { dtb_embed_begin = .; KEEP(*(.mydtb)); -- 2.25.1

[PATCH 0/8] SUNIV SPI NAND support in SPL
by Icenowy Zheng 11 Apr '24

11 Apr '24

This patchset tries to extend SPI-based boot code in sunxi SPL to support SPI NAND, following the same principle with current SPI NOR code (mimicking the behavior of sunxi BROM). In addition, as part of test to this patchset, some patches for Source Parts Inc. PopStick is attached, although marked DO NOT MERGE because the DT should come from Linux after it's ready. To keep thr code that accesses SPI NAND as simple as possible, it assumes fixed page size, which is also what sunxi BROM does. The SUNIV SPL assumes 0x400 page size, but here to utilize the space better, in the attached example of PopStick, U-Boot main part is assumed to be with 0x800 page size (which is the real situation of the W25N01 flash used by PopStick). Icenowy Zheng (8): sunxi: SPL SPI: extract code for doing SPI transfer sunxi: SPL SPI: add support for read command with 2 byte address sunxi: SPL SPI: allow multiple boot attempt sunxi: SPL SPI: add initial support for booting from SPI NAND sunxi: enable support for SPI NAND booting on SUNIV [DO NOT MERGE] sunxi: sync DT from my tree for PopStick [DO NOT MERGE, DIRTY HACK] sunxi: use UBI for environement storage [DO NOT MERGE] sunxi: add a defconfig for PopStick arch/arm/dts/Makefile | 3 +- arch/arm/dts/suniv-f1c100s-licheepi-nano.dts | 16 ++ arch/arm/dts/suniv-f1c100s.dtsi | 26 ++ arch/arm/dts/suniv-f1c200s-popstick-v1.1.dts | 101 ++++++++ arch/arm/mach-sunxi/Kconfig | 16 ++ arch/arm/mach-sunxi/board.c | 4 +- arch/arm/mach-sunxi/spl_spi_sunxi.c | 247 ++++++++++++++----- board/sunxi/board.c | 1 + configs/popstick_defconfig | 35 +++ 9 files changed, 377 insertions(+), 72 deletions(-) create mode 100644 arch/arm/dts/suniv-f1c200s-popstick-v1.1.dts create mode 100644 configs/popstick_defconfig -- 2.37.1

[PATCH 00/33] doc: board: amlogic: spring clean-up of Amlogic docs
by Christian Hewitt 05 Apr '24

05 Apr '24

Amlogic documentation spans U-Boot support from 2015-current resulting in older content being harder to follow. And due to many international contributors the docs also contain grammar quirks. This series reworks all board documents to be more consistent. There is deliberate emphasis on using the amlogic-boot-fip repo for signing tasks as this is easier for most users to follow. The original/longer signing process (described as Manual Signing) has been tidied up. In the index.rst file I've dropped board names from the features table as this adds considerable width and makes adding new boards a fiddly process. I've appended the SoC type to the boader header so it shows in the TOC list to retain a reference between boards and the table. I've added missing board docs for GS-King-X, BPI-M5, BPI-CM4IO, and we split ODROID-HC4 into its own document. It originally followed the same process as the ODROID0-C4, but now has a separate defconfig to enable SPI-NOR and PCIe SATA support. Users occasionally follow the current doc and build U-Boot for the C4 which omits this and then struggle to figure out why SATA boot doesn't work when wiki/forums say it does. There are other minor cleanups and tweaks for clarity of simply more up-to-date information for a board or process. Please review and flag any omissions or issues!

Please hold off merging this patch until someone tested it, I can not do so this week. @Tom Can you confirm if this fixes the networking on your Cubox? Also note that the phy-handle property may or may not be required, I am not sure. sincerely Josua Mayer On Thu, Jul 28, 2022 at 7:05 AM Josua Mayer <josua(a)solid-run.com> wrote: > The i.MX6 Cubox-i and HummingBoards can have different PHYs at varying > addresses.

[PATCH v2] smbios: Fix table when no string is present
by matthias.bgg＠kernel.org 31 Jan '24

31 Jan '24

From: Matthias Brugger <mbrugger(a)suse.com> When no string is present in a table, next_ptr points to the same location as eos. When calculating the string table length, we would only reserve one \0. By spec a SMBIOS table has to end with two \0\0 when no strings a present.

[PATCH v1] qemu-arm: round down memory to multiple of 2MB
