[U-Boot] [PATCH 4/5] Kconfig: mx6ull: Deselect MX6UL from CONFIG_MX6ULL
by Breno Lima 03 Jan '18

03 Jan '18

From: Breno Lima <breno.lima(a)nxp.com> MX6UL contains features that MX6ULL doesn't support. Deselect CONFIG_MX6UL and select SYS_L2CACHE_OFF and ROM_UNIFIED_SECTIONS. The motivation for doing this change is that MX6UL supports CAAM and MX6ULL does not.

[U-Boot] [PATCH] mx6: Add board mx6memcal for use in validating DDR
by Fabio Estevam 03 Jan '18

03 Jan '18

From: Eric Nelson <eric(a)nelint.com> This is a virtual "board" that uses configuration files and Kconfig to define the memory layout used by a real board during the board bring-up process. It generates an SPL image that can be loaded using imx_usb or SB_LOADER.exe. When run, it will generate a set of calibration constants for use in either or both a DCD configuration file for boards that use u-boot.imx or struct mx6_mmdc_calibration for boards that boot via SPL. In essence, it is a configurable, open-source variant of the Freescale ddr-stress tool. https://community.nxp.com/docs/DOC-105652 File mx6memcal_defconfig configures the board for use with mx6sabresd or mx6qsabreauto. Signed-off-by: Eric Nelson <eric(a)nelint.com> Signed-off-by: Fabio Estevam <fabio.estevam(a)nxp.com> --- This is an attempt to bring Eric's useful patch to life: https://lists.denx.de/pipermail/u-boot/2016-November/271597.html Changes since RFC: - Rebased against latest U-Boot - Removed get_imx_type() as it does not build with SPL (to be added lates). - Include patch 2/9 into this one: https://lists.denx.de/pipermail/u-boot/2016-November/271596.html ,otherwise mmdc_do_dqs_calibration() always fail on my tests with mx6qsabresd - Fixed some Coding

hey, i have looked at this thread: http://u-boot.10912.n7.nabble.com/QSPI-quot-sf-probe-quot-quot-sf-read-quot… i'm having the same problem with Arria 5, when i try to use the "sf probe" command on the nor flash, the result i'm getting0 is: SF: Detected n25q512 with page size 256 Bytes, erase size 64 KiB, total 64 MiB ### ERROR ### Please RESET the board ### i have already tried to use the patches for the uboot code and also to add more defines before making the uboot, but it still doesn't work for me. any ideas? thanks ahead. -- Sent from: http://u-boot.10912.n7.nabble.com/

[U-Boot] [PATCH v2] mx6ull: Handle the CONFIG_MX6ULL cases correctly
by Fabio Estevam 03 Jan '18

03 Jan '18

From: Fabio Estevam <fabio.estevam(a)nxp.com> Since commit 051ba9e082f7 ("Kconfig: mx6ull: Deselect MX6UL from CONFIG_MX6ULL") CONFIG_MX6ULL does not select CONFIG_MX6UL anymore, so take this into consideration in all the checks for CONFIG_MX6UL.

[U-Boot] [PATCH V4] Convert CONFIG_SOC_DA8XX et al to Kconfig
by Adam Ford 02 Jan '18

02 Jan '18

This converts the following to Kconfig: CONFIG_SOC_DA8XX CONFIG_SOC_DA850 CONFIG_DA850_LOWLEVEL CONFIG_MACH_DAVINCI_DA850_EVM CONFIG_SYS_DA850_PLL_INIT CONFIG_SYS_DA850_DDR_INIT Signed-off-by: Adam Ford <aford173(a)gmail.com> --- Changes in V4: Rebase against origin/master Changes in V3: Add bool for DA850_LOWLEVEL and make it select DA850_PLL_INIT and DA850_DDR_INIT Make OMAPL138_LCDK select SOC_DA8XX instead of SOC_DA850. The name of CONFIG_SOC_DA8XX was left alone here since it wasn't my goal to change the naming convention. WhileDA850 is probably correct, it would technically be a change to the compiled code and that wasn't the goal here.

This converts the following to Kconfig: CONFIG_SOC_DA8XX CONFIG_SOC_DA850 CONFIG_DA850_LOWLEVEL CONFIG_MACH_DAVINCI_DA850_EVM CONFIG_SYS_DA850_PLL_INIT CONFIG_SYS_DA850_DDR_INIT Signed-off-by: Adam Ford <aford173(a)gmail.com> --- Changes in V3: Add bool for DA850_LOWLEVEL and make it select DA850_PLL_INIT and DA850_DDR_INIT Make OMAPL138_LCDK select SOC_DA8XX instead of SOC_DA850. The name of CONFIG_SOC_DA8XX was left alone here since it wasn't my goal to change the naming convention. WhileDA850 is probably correct, it would technically be a change to the compiled code and that wasn't the goal here.

[U-Boot] [PATCH v5 1/2] drivers/reset: support rockchip reset drivers
by Kever Yang 02 Jan '18

02 Jan '18

From: Elaine Zhang <zhangqing(a)rock-chips.com> Create driver to support all Rockchip SoCs soft reset. Example of usage: i2c driver: ret = reset_get_by_name(dev, "i2c", &reset_ctl); if (ret) { error("reset_get_by_name() failed: %d\n", ret); } reset_assert(&reset_ctl); udelay(50); reset_deassert(&reset_ctl); i2c dts node: resets = <&cru SRST_P_I2C1>, <&cru SRST_I2C1>; reset-names = "p_i2c", "i2c"; Signed-off-by: Elaine Zhang <zhangqing(a)rock-chips.com> Signed-off-by: Kever Yang <kever.yang(a)rock-chips.com> --- Changes in v5: - make rockchip reset driver depends on ARCH_ROCKCHIP Changes in v4: None Changes in v3: None Changes in v2: - fix Kconfig more than 80 length - use MACRO for reset bits in one reg - use rkclr/set_reg for reg access - add rockchip_reset_bind() - use dev_read_addr_size() instead of fdtdec_ drivers/reset/Kconfig | 9 +++ drivers/reset/Makefile | 1 + drivers/reset/reset-rockchip.c | 133 +++++++++++++++++++++++++++++++++++++++++ 3 files changed, 143 insertions(+) create mode 100644 drivers/reset/reset-rockchip.c diff --git a/drivers/reset/Kconfig b/drivers/reset/Kconfig index ce46e27..3964b9e 100644 --- a/drivers/reset/Kconfig +++ b/drivers/reset/Kconfig @@ -74,4 +74,13 @@ config AST2500_RESET resets that are supported by watchdog.
