[PATCH] toradex: tdx-cfg-block: add new toradex oui range
by Philippe Schenker 07 Jul '22

07 Jul '22

From: Philippe Schenker <philippe.schenker(a)toradex.com> Add new Toradex MAC OUI (8c:06:cb), to the config block. With this change we extend the possible serial-numbers as follows: For serial-numbers 00000000-16777215 OUI 00:14:2d is taken For serial-numbers 16777216-33554431 OUI 8c:06:cb is taken Lower 24-bit of the serial number are used in the NIC part of the MAC address, the complete serial number can be calculated using the OUI.

[PATCH 0/5] board: ti: am62x: Add support for 1-bit inline DDRSS ECC
by Georgi Vlaev 07 Jul '22

07 Jul '22

Hi, This series enables the 1-bit inline DDR ECC support in the TI DDRSS bridge for AM62x. The base DDRSS ECC support was merged for k3-ddrss in a previous series for AM64x [1]. The ECC data is stored together with the data, which will reduce the total available memory with 1/9th. The k3-ddrss driver enables the ECC support and primes the full memory from the R5 SPL, so the the memory size changes must propagate from the R5 SPL to A53 SPL and then to A53 u-boot. The patches are similar to those we have for AM64x, with one exception: "arm: mach-k3: common: Use ddr_init in spl_enable_dcache". Since we've switched the boards to DT to fetch the memory configuration, dram_init_banksize() will no longer set the total memory size in the global data. And spl_enable_dcache() uses dram_init_banksize() instead of dram_init(), which actually sets the memory base/size. Note this doesn't enable the 1-bit ECC on any platform by default. This can be done by adding the "ti,ecc-enable" property to the memorycontroller node in k3-am6*-ddr.dtsi. [1] https://lore.kernel.org/u-boot/20220317170346.31162-1-d-gerlach@ti.com/ The patches depend on the base AM62 support, which was recently merged in u-boot/next.

[PATCH v3 0/2] Add support for dynamic overriding of default SF bus
by Vaishnav Achath 07 Jul '22

07 Jul '22

Currently the SPI flash to load from is defined through the compile time config CONFIG_SF_DEFAULT_BUS and CONFIG_SF_DEFAULT_CS, this prevents the loading of binaries from different SPI flash using the same build. This series adds support for choosing the flash device based on the selected boot device thus allowing platforms to override the SF_BUS and SF_CS to load from the desired flash. Changes tested on J721E for OSPI and QSPI boot. V1->V2: * drop unnecessary Kconfig option for SF bus override, suggested by Heiko Schocher. V2->V3 * drop unnecessary spl_spi_boot_cs() override for J721E, suggested by Pratyush Yadav Vaishnav Achath (2): common: spl: spl_spi: add support for dynamic override of sf bus arm: k3: j721e: add dynamic sf bus override support for j721e arch/arm/mach-k3/j721e_init.c | 11 +++++++++++ arch/arm/mach-k3/sysfw-loader.c | 4 ++-- common/spl/spl_spi.c | 16 +++++++++++++--- include/spl.h | 16 ++++++++++++++++ 4 files changed, 42 insertions(+), 5 deletions(-) -- 2.17.1

[PATCH] Kconfig: Fix SYS_MALLOC_F_LEN for i.MX8MQ
by Peng Fan (OSS) 07 Jul '22

From: Peng Fan <peng.fan(a)nxp.com> i.MX8MQ use SYS_MALLOC_F_LEN 0x2000, not 0x10000. The OCRAM_S only has 32KB memory, use 0x10000 will make SPL not bootable.

[ANN] U-Boot v2022.01-rc3 released
by Tom Rini 06 Jul '22

06 Jul '22

Hey all, It's been two weeks since v2022.01-rc2, so here's -rc3. To repeat what I said with -rc2, we've enabled issue tracking on our gitlab instance. You can sign up and then be able to file issues at: https://source.denx.de/groups/u-boot/-/issues This is intended for everyone to be able to use, both custodians for their own needs (you can see for example Heinrich has filed something for UEFI and LMB) as well as users to just report bugs so they don't feel like they're lost in the mailing list. As noted with the last release, the -next branch is open and I'll sync in -rc3 shortly. Please feel free to get a PR ready now if you're able. In terms of a changelog, git log --merges v2022.01-rc2..v2022.01-rc3 contains what I've pulled but as always, better PR messages and tags will provide better results here. So we're now looking at regular releases every other Monday, and with final release on January 10th, 2022. Thanks all! -- Tom
