[PATCH v2 0/2] qcom: allow msm_gpio to set special pins direction & value
by Neil Armstrong 02 Oct '24

02 Oct '24

After struct msm_special_pin_data was introduced in [1], use the data to setup the pin direction and/or value if supported by the pin data. Add the proper msm_special_pin_data for sm8250 after sm8550 and sm8650.

Calling u_boot_console.restart_uboot() in test_efi_selftest_watchdog_reboot() may lead to incorrect results. While the watchdog triggered reboot is running thee test environment may need some time before triggering a reboot itself.

[PATCH 00/26] Support display (and even more) on the BSH SMM S2/PRO boards
by Dario Binacchi 01 Oct '24

01 Oct '24

This series was created out of the need to supportsimple-framebuffer for BSH boards SMM_S2 and SMM_S2PRO. To achieve this goal, it was necessary to develop additional code and/or drivers for all the required components (i. e. clock, power domain, video, etc.). This series has a Linux counterpart that will also be submitted upstream as soon as possible. Furthermore, given the overlap in topics with the recent series [1], we are open to collaborate on the common parts to ensure proper development.

[PATCH v9 00/13] net: tcp: improve tcp support
by Mikhail Kshevetskiy 01 Oct '24

01 Oct '24

U-Boot support of LWIP is not ready for a moment, but we already have some kind of tcp support. Unfrotunately this support is really bad. Some of the known issues: * tcp packet from other connection can break a current one * tcp send sequence always starts from zero * bad tcp options processing * strange assumptions on packet size for selectiv acknowledge * tcp interface assumes one of the two scenarios: - data downloading from remote host to a board - request-response exchange with a small packets so it's not possible to upload large amount of data from the board to remote host. * wget test generate bad tcp stream, test should fail but it passes instead This series of patches fixes all of the above issuess. The benefits: * A lot of bug was fixed * Better and more reliable TCP state machine * Tcp cliens becomes smaller/simpler * Data uploading was fixed (now it's possible to transmit a huge amount of data from the board to remote host) * Netcat over tcp was implemented. Netcat supports data downloading/uploading from/to remote host in client/server mode. * An example web-server implementation. This code can be used as a base for web-based firmware uploading used by some vendors. Modification was verified with * firmware downloading via u-boot wget command * fastboot over tcp * netcat linux client * Firefox/Chrome/Edge using example web-server implementation Changes v2: * cover letter was added * some patches were removed Changes v3: * better cover letter Changes v4: * fix bug in debug output * add more comments * codestyle fixes Changes v5: * old patches were ocasionally sent with v4 * add back web-server patches * fix bug in debug output * add more comments * codestyle fixes Changes v6: * fix the wget test * improve description of "simplify tcp header filling code" patch Changes v7: * fix include ordering * improve option descriptions * fix a lot of extra brackets and comparisons against NULL / 0 * add empty lines before final returns * fixed a bug with zero size httpd uploads Changes v8: * [tcp] add function to restart rx inactivity timeout. This may help in the cases where remote peer waits for u-boot data, but u-boot is busy with long executing action * [httpd] add function returning underlying tcp stream from request id. This (with the above change) allows avoid connection break for the long processing post requests. Changes v9: * rebase all changes on top of origin/next * update test/cmd/wget patch description (bad tcp ack/seq issue was already fixed in origin/next) * tcp: add rx/tx packet counters to a tcp_stream structure * wget: use tcp rx packet counter instead of own one * netcat: use tcp rx/tx packet counters instead of own one Mikhail Kshevetskiy (13): net/tcp: fix TCP options processing net/tcp: fix selective acknowledge net/tcp: put connection specific data into a tcp_stream structure net/tcp: add connection info to tcp_stream structure net/tcp: rename ack_edge and seq_init to more common rcv_nxt and irs net/tcp: improve tcp framework, use better state machine test/cmd/wget: fix the test net/tcp: simplify tcp header filling code net/tcp: define a fallback value for rcv_wnd size net/net: fix include ordering net/netcat: add netcat over tcp support net/httpd: add httpd common code net/httpd-upload: an example web-server implementation for file uploading arch/sandbox/include/asm/eth.h | 4 + cmd/Kconfig | 35 + cmd/net.c | 55 +- include/net.h | 7 +- include/net/httpd-upload.h | 12 + include/net/httpd.h | 71 ++ include/net/netcat.h | 20 + include/net/tcp.h | 254 ++++++- include/net/wget.h | 8 - net/Kconfig | 14 + net/Makefile | 3 + net/fastboot_tcp.c | 193 +++-- net/httpd-upload.c | 170 +++++ net/httpd.c | 735 ++++++++++++++++++ net/net.c | 60 +- net/netcat.c | 191 +++++ net/tcp.c | 1266 ++++++++++++++++++++++---------- net/wget.c | 476 ++++-------- test/cmd/wget.c | 58 +- 19 files changed, 2723 insertions(+), 909 deletions(-) create mode 100644 include/net/httpd-upload.h create mode 100644 include/net/httpd.h create mode 100644 include/net/netcat.h create mode 100644 net/httpd-upload.c create mode 100644 net/httpd.c create mode 100644 net/netcat.c -- 2.45.2

[PATCH 0/3] env: mmc: fix use of two separate partitions with proper type GUID
by Rasmus Villemoes 01 Oct '24

01 Oct '24

I always define a disk layout with two separate partitions for the two copies of the U-Boot environment and, being the one who introduced the type GUID for such partitions, of course also set those partitions' type GUID appropriately. This has worked just fine, but, it turns out, only because I've never had CONFIG_PARTITION_TYPE_GUID enabled on any of my boards; I've always just set the offsets of the two partitions via the config variables CONFIG_ENV_OFFSET(,_REDUND). I didn't even know that env/mmc.c had learnt to look for the env partition based on the type GUID, or that that would overrule the ENV_OFFSET config variables, until I experienced weird random corruption while doing bringup for an stm32 board, where PARTITION_TYPE_GUID is automatically set because it is select'ed by CMD_STM32PROG. These patches try to fix the code to fit my scheme, while not changing anything for existing setups that use the two-copies-one-partition scheme, other than complaining loudly if the system is misconfigured and avoiding such random corruption of neighbouring partitions. Rasmus Villemoes (3): env: mmc: refactor mmc_offset_try_partition() env: mmc: do not return an offset before the start of the partition env: mmc: rework mmc_env_partition_by_guid() to work with two separate partitions env/mmc.c | 95 ++++++++++++++++++++++++++++++++++++++++++++----------- 1 file changed, 77 insertions(+), 18 deletions(-) -- 2.46.0
