[PATCH] ARM: zynq: Remove deprecated device_type property

Based on DT specification device_type property is deprecated and should be used only for cpu and memory nodes. That's why remove other usage. In this case ethernet-phy.

[PATCH] arm: apple: t602x: Add missing MMIO regions to memmap
by Janne Grunau via B4 Relay 30 Nov '23

30 Nov '23

From: Janne Grunau <j(a)jannau.net> The memory maps for Apple's M2 Pro/Max/Ultra left MMIO space out which was not used by any driver at the time. The display out exposed as simple-framebuffer use a power-domain controlled by a device in an unmapped region. Add a map covering this region as well as another MMIO region in the range 0x4'0000'0000 - 0x5'0000'0000. The added regions cover all MMIO annotated in Apple's device tree in this range.

[RFT PATCH 0/2] mmc: meson-gx: improve MMC reliabilty
by Jerome Brunet 30 Nov '23

30 Nov '23

Amlogic MMC on the GX (and later) SoCs has been problematic for years, especially with u-boot. Linux has been fairly stable for a few years. It is using a fixed phase setting with Core = 180, Tx = 0 and Rx = 0 (the latter cannot be set starting from the v3 MMC IPs) Still the results were not good with those settings with u-boot, on some sm1 based platforms. U-boot then started using a 270 core phase for sm1 only. This worked for most sm1 platforms but problems persist on others. The proposal with this patchset is to use 270 for the ID phase, 180 otherwise. This works well on the platforms I have tested (Libretech's boards and VIM3L) It would be great if others could test this and report whether this work for them or not. If the results are good, this might be ported to Linux as well (... but the situation is less critical there) Jerome Brunet (2): mmc: meson-gx: clean up and align on Linux settings mmc: meson-gx: set 270 core phase during the identification drivers/mmc/meson_gx_mmc.c | 50 ++++++++++++++++++-------------------- drivers/mmc/meson_gx_mmc.h | 9 +++++-- 2 files changed, 31 insertions(+), 28 deletions(-) -- 2.40.1

[PATCH v3 0/5] Implement fastboot multiresponce
by Svyatoslav Ryhel 30 Nov '23

30 Nov '23

Currently u-boot fastboot can only send one message back to host, so if there is a need to print more than one line messages must be kept sending until all the required data is obtained. This behavior can be adjusted using multiresponce ability (getting multiple lines of response) proposed in this patch set. Implementation of multiresponce leads to ability to dump content of console buffer which, with use of "oem run", allows to entirely avoid need in UART. --- Changes from v2: - fix missing function calls if CONFIG_CONSOLE_RECORD is not enabled Changes from v1: - changed variables to static - fixed multiresponce for udp - documented use of "MORE" - converted #if to if (...) --- Ion Agorria (5): fastboot: multiresponse support fastboot: implement "getvar all" common: console: introduce overflow and isempty calls lib: membuff: fix readline not returning line in case of overflow fastboot: add oem console command support boot/bootmeth_extlinux.c | 2 +- common/console.c | 17 +++++-- doc/android/fastboot-protocol.rst | 3 ++ doc/android/fastboot.rst | 1 + drivers/fastboot/Kconfig | 7 +++ drivers/fastboot/fb_command.c | 52 +++++++++++++++++++++ drivers/fastboot/fb_getvar.c | 77 +++++++++++++++++++++++++------ drivers/usb/gadget/f_fastboot.c | 29 ++++++++++++ include/console.h | 26 +++++++++++ include/fastboot-internal.h | 7 +++ include/fastboot.h | 19 ++++++++ include/membuff.h | 5 +- lib/membuff.c | 4 +- net/fastboot_udp.c | 29 +++++++++--- test/ut.c | 9 ++-- 15 files changed, 254 insertions(+), 33 deletions(-) -- 2.40.1

[RK3568] Default kernel_comp_addr_r can be too narrow
by MichaIng 29 Nov '23

29 Nov '23

Hey guys, for our PINE64 Quartz64 images, I am working on moving from an older U-Boot fork (by Peter Geis', but rebased until v2022.07: https://gitlab.com/MichaIng/u-boot) to upstream U-Boot. But I was running into an error on boot: ERROR: Did not find a cmdline Flattened Device Tree It turned out to be the different kernel_comp_addr_r: - I implemented it at 0x10000000, hence after fdt_addr_r: https://gitlab.com/MichaIng/u-boot/-/commit/170514b - Upstream it is 0x08000000, hence before fdt_addr_r: https://github.com/u-boot/u-boot/commit/e1962a9 I am actually not sure why 0x08000000 (128M) causes an issue, since with kernel_comp_size=0x2000000 (32M) it should end just before fdt_addr_r (128M+32M=160M<161M). But "setenv kernel_comp_addr_r 0x10000000" was all it took to successfully boot the image. If someone wants to try replicating it: Our compressed Linux image is 13M, the decompressed one 35M. In case the smallest RAM sizes of RK3568 SBCs are 512M or more, it should be safe to move the default address to 256M. In my fork we also allow a compressed kernel size of 128M, but I doubt that more than 32M would ever be required (not in our case). I can open a PR with this change, but probably I am interpreting something wrong, or it is not wanted for other reasons. Just let me know. -- Best regards, Micha (aka MichaIng) DietPi project lead

[PATCH v5 0/5] Populate kaslr seed with RNG
by seanedmond＠linux.microsoft.com 29 Nov '23

29 Nov '23

From: Sean Edmond <seanedmond(a)microsoft.com> This patch series creates a common API (fdt_fixup_kaslr_seed()) for populating the kaslr seed in the DTB. Existing users (kaslrseed, and ARMv8 sec firmware) have been updated to use this common API. New functionality has been introduced to populate the kaslr using the RNG. This can be enabled with CONFIG_RNG_TPM_SEED. changes in v5: - Always enable OFNODE_MULTI_TREE - include dm/ofnode-decl.h instead of dm/ofnode.h - cast buffer to (u8 *) in kaslrseed.c changes in v4: - Fix compile issue when CONFIG_OF_CONTROL not set changes in v3: - Populate with RNG device instead of TPM device (this is a more generic solution) - Use event spy to do the FDT fixup - fix compile error for sandbox for !OFNODE_MULTI_TREE changes in v2: - fdt_fixup_kaslr_seed() uses the ofnode API - Add root_ofnode_from_fdt() to get the root node from an FDT and perform error checking on the oftree - add comments to exported functions - Add error checking in image_setup_libfdt() for return from fdt_tpm_kaslr_seed() - uclass_get_device() -> uclass_first_device_err() - Change default config for OFNODE_MULTI_TREE (y if !OF_LIVE) Dhananjay Phadke (2): fdt: common API to populate kaslr seed fdt: kaslr seed from RNG device Sean Edmond (3): cmd: kaslrseed: Use common API to fixup FDT dm: core: Modify default for OFNODE_MULTI_TREE fdt: Fix compile error for !OFNODE_MULTI_TREE arch/arm/cpu/armv8/sec_firmware.c | 39 ++++++++-------------- boot/fdt_support.c | 55 +++++++++++++++++++++++++++++++ cmd/kaslrseed.c | 22 +++++-------- drivers/core/Kconfig | 3 +- drivers/core/ofnode.c | 29 ++++++++++++---- include/dm/ofnode.h | 12 +++++++ include/fdt_support.h | 9 +++++ lib/Kconfig | 7 ++++ 8 files changed, 130 insertions(+), 46 deletions(-) -- 2.42.0
