[U-Boot] [PATCH v3 0/9] Add SoC and Board support for Bubblegum-96
by Manivannan Sadhasivam 10 Jul '18

10 Jul '18

This patchset adds SoC support for Actions Semi S900 SoC and ucRobotics Bubblegum-96 board along with UART and Clock drivers. S900 SoC consists of 4 ARM Cortex-A53 cores up to 1.8GHz with Imagination Power VR G6230 GPU. More information on this SoC can be found in Actions Semi product page: http://www.actions-semi.com/en/productview.aspx?id=204 Bubblegum-96 board is one of the 96Boards Consumer Edition platform based on S900 SoC. This board has 2GB LPDDR3 operating at 533 MHz and 8GB eMMC along with other peripherals required by 96Boards Consumer Edition Specification. More information on this board can be found in 96Boards product page. https://www.96boards.org/product/bubblegum-96/ Most of the code is based on Actions tree found here: https://github.com/96boards-bubblegum/u-boot/ With this patchset, Bubblegum-96 board can boot into U-Boot shell.

[U-Boot] [PATCH v6 0/5] drivers: Add reset ctrl to drivers
by Ley Foon Tan 10 Jul '18

10 Jul '18

Add reset ctrl to dwmmc socfpga, designware Ethernet and ns16550 serial drivers. A reset property is an optional feature, so only print out a warning and do not fail if a reset property is not present. If a reset property is discovered, then use it to deassert, thus bringing the IP out of reset. v6: - Include change history to patches and cover letter - Added Joe's Acked-by in designware emac patch. v5: https://patchwork.ozlabs.org/cover/924857/ - Rename CONFIG_SPL_RESET_SUPPORT to CONFIG_SPL_DM_RESET - Change to use CONFIG_IS_ENABLED(DM_RESET) in reset.h - Added Simon's Reviewed-by in dwmmc, 16550 serial and designware emac patches. v4: https://patchwork.ozlabs.org/cover/923883/ - Add patch to check CONFIG_SPL_RESET_SUPPORT in reset.h v3: https://patchwork.ozlabs.org/cover/910018/ - remove #ifdef CONFIG_DM_RESET switch - add maintainer emails v2: https://patchwork.ozlabs.org/cover/908667/ - remove 'return' in designware emac driver - keep reset control in socfpga_dw_mmc.c because it didn't call to common dwmmc probe function when in SPL. - add reviewed-by in ns16550 patch v1: https://patchwork.ozlabs.org/cover/905519/ Ley Foon Tan (5): reset: Rename CONFIG_SPL_RESET_SUPPORT to CONFIG_SPL_DM_RESET include: reset: Change to use CONFIG_IS_ENABLED(DM_RESET) mmc: dwmmc: socfpga: Add reset ctrl to driver serial: ns16550: Add reset ctrl to driver net: designware: Add reset ctrl to driver arch/arm/mach-stm32mp/Kconfig | 2 +- common/spl/Kconfig | 2 +- drivers/Makefile | 2 +- drivers/mmc/socfpga_dw_mmc.c | 17 +++++++++++++++++ drivers/net/designware.c | 8 ++++++++ drivers/serial/ns16550.c | 8 ++++++++ include/reset.h | 2 +- 7 files changed, 37 insertions(+), 4 deletions(-) -- 2.2.2

[U-Boot] [PATCH v3 0/2] Add MDIO driver model support
by make＠marvell.com 09 Jul '18

09 Jul '18

From: Ken Ma <make(a)marvell.com> Changes in v3: - Move mdio uclass implementation to driver/net folder; - Replace flat-tree functions with livetree functions and update codes and comments to be consistent with driver-model codes style; - Put struct mii_dev to uclass platdata to avoid the mdio alloc and let driver model framework to alloc the memroy automatically, meanwhile the mii bus link initialization is added, - Move marvell mdio driver to driver/net/mdio folder; - Update codes according to mdio uclass implementation updates. Changes in v2: - Fix error printing: - Change some debug to pr_err; - mii bus has no parent member and it is not a udevice, so dev_err is changed to pr_err for mii bus error printings.

[U-Boot] [PATCH v3] tegra: nyan-big: Update CONFIG_SYS_TEXT to the default in README.chromium
by Peter Robinson 06 Jul '18

06 Jul '18

To build U-Boot on a Nyan Big Chromebook the docs outline adjusting the Tegra124 defined CONFIG_SYS_TEXT_BASE but this has since been moved to individual config files. We should have the default required for U-Boot chain loading on the chromebook as the default CONFIG_SYS_TEXT_BASE and update the docs to remove this now non required step.

[U-Boot] [PATCH 0/2] sunxi: Fix MMC driver crashes
by Andre Przywara 05 Jul '18

05 Jul '18

There were recent reports about MMC operations failing very often on boards with the Allwinner A64 SoC. Investigations pointed to a time issue, and indeed a recent patch [1] introduced frequent arch timer reads to the Allwinner MMC driver. Reverting this patch made the problems go away, but also hurt performance much. Unrelated reports also confirmed an Allwinner A64 arch timer erratum[2], which can lead to erroneous counter reads, where the lower 11 bits become either all 0's or all 1's. This leads to random jumps forwards and backwards, with catastrophic consequences. These two patches fix the issue, while retaining the much improved MMC performance. The first patch refactors an already existing arch timer fix, to allow the second patch, introducing an Allwinner specific workaround, to fit it more nicely. Please have a look and apply as soon as possible. Cheers, Andre.
