[PATCH] mmc: dwmmc: only clear handled interrupts
by John Keeping 25 Oct '22

25 Oct '22

Unconditionally clearing DTO when RXDR is set leads to spurious timeouts in FIFO mode transfers if events occur in the following order: mask = dwmci_readl(host, DWMCI_RINTSTS); // Hardware asserts DWMCI_INTMSK_DTO here dwmci_writel(host, DWMCI_RINTSTS, DWMCI_INTMSK_DTO); if (mask & DWMCI_INTMSK_DTO) { // Unreachable as DTO is cleared without being handled! return 0; } Only clear interrupts that we have seen and are handling so that DTO is not missed.

[PATCH 1/3] mmc: stm32_sdmmc2: add dual data rate support
by Yann Gautier 25 Oct '22

25 Oct '22

To support dual data rate with STM32 sdmmc2 driver, the dedicated bit (DDR - BIT(18)) needs to be set in the CLKRC register. Clock bypass (no divider) is not allowed in this case. This is required for the eMMC DDR modes.

Get rid of discrepancy beween comment /* 250 ms */ and code which shifts by 4 thus dividing by 16. So change code to shift by 2 and make the timeout value 250 ms.

[PATCH v3 0/3] verdin-imx8mm: verdin-imx8mp: various additions and improvements
by Marcel Ziswiler 24 Oct '22

24 Oct '22

From: Marcel Ziswiler <marcel.ziswiler(a)toradex.com> Various additions and improvements for the Verdin iMX8M Mini and Verdin iMX8M Plus: - updated env memory layout - verdin-imx8mm: prepare for optional job ring driver model (already applied) - verdin-imx8mm: improve and extend boot devices (already applied) - various config additions and improvements Changes in v3: - Moved loadaddr back by 0.5MB as I meanwhile found out that it is actually a property of the kernel binary whether or not any additional moving/relocation will (need) to be done. However, a pre-maturely applied v2 did not take that into account as of yet [1]. [1] https://patchwork.ozlabs.org/project/uboot/cover/20220822130604.843081-1-ma… - Drop SNVS_LP general purpose register LPGPR0 based bootcount integration in favour of using the environment based one as that is what our update system uses. - Update patch 1 again after wrong version got pre-maturely epplied. - Drop patches 2 and 3 which already got applied. - Drop SNVS_LP general purpose register LPGPR0 based bootcount integration in favour of using the environment based one as that is what our update system uses. Changes in v2: - Moved loadaddr by an additional 0.5MB to avoid "Moving Image from 0x48200000 to 0x48280000" during booti plus increasing kernel_comp_size by same 0.5MB.

[PATCH v4 0/4] net: Enable NC-SI support
by Joel Stanley 24 Oct '22

24 Oct '22

Back in 2019 Sam submitted NC-SI support. The NC-SI PHY driver was merged (patches 1 and 2), but we never got around to merging patches 3 and 4: https://lore.kernel.org/u-boot/20190618013720.2823-1-sam@mendozajonas.com/ Sam as long since moved on from working on the Aspeed BMCs, but the code has been in use in the vendor fork for some time. This refreshes his patches and enables support in the Aspeed defconfigs, giving compile coverage to the NC-SI phy. v4 splits the ncsi integration and cmd code into separate patches, and adds r-b from Ramon and Cédric to patches 3 and 4.

[PATCH 0/4] handle watchdogs during keyed autoboot
by Rasmus Villemoes 24 Oct '22

24 Oct '22

The fix and explanation is in the first patch, which I hope can make it into v2022.10, it should be rather uncontroversial. The second patch may make sense on its own, but is not at all urgent and can be considered a mere suggestion, but it was convenient for making the following two patches less intrusive. While I noticed this on my actual hardware, it's not too hard to verify the problem in sandbox, which is what patches 2-4 are for. More precisely, I've tested that with this series (and the stuff added by the first patch temporarily commented out), building sandbox64_defconfig modified by setting CONFIG_BOOTDELAY=15 and CONFIG_AUTOBOOT_KEYED=y, doing ./u-boot -D works as always (ordinary simple autoboot, getting a prompt after 15 seconds), while with ./u-boot -D --autoboot_keyed the sandbox gets killed as expected five seconds into the 15 second countdown. And with the first patch properly applied, this is fixed. I don't know if this is a good way to test this, or if having that SIGALRM based watchdog device running always in sandbox can cause problems for other uses of sandbox. I also won't have time in the near future for polishing or reworking the test, so consider it mostly POC. Regardless, as I wrote above, I do hope the fix itself (1/4) can be applied soonish.
