[PATCH 1/4] i2c: Make deblock delay and SCL clock configurable
by Marek Vasut 17 Mar '20

17 Mar '20

Make the delay between SCL line changes and the number of SCL clock changes configurable as a parameter of the deblock function. No functional change.

[PATCH] watchdog: Handle timer wrap around
by Chris Packham 16 Mar '20

16 Mar '20

On some platforms/architectures the value from get_timer() can wrap. This is particularly problematic when long-running code needs to measure a time difference as is the case with watchdog_reset() which tries to avoid tickling the watchdog too frequently. Use time_after() from time.h instead of a plain > comparison to avoid any issues with the time wrapping on a system that has been sitting in u-boot for a long time.

[PATCH] watchdog: Use dev_read only if OF_PLATDATA is not enabled
by Walter Lozano 16 Mar '20

16 Mar '20

Currently watchdog tries to use dev_read_u32_default to get timeout configuration in case OF_CONTROL is enabled. However, if SPL is built with OF_PLATDATA this has no sense as there is no device tree. This patch fixes this issue by only use dev_read_u32_default if OF_CONTROL is enabled but OF_PLATDATA is not.

[PATCH] rk3399: Add four clocks to clock driver needed by framebuffer
by Wolfram Joost 15 Mar '20

15 Mar '20

This patch adds the four clock gates - ACLK_VOP0 - ACLK_VOP1 - HCLK_VOP0 - HCLK_VOP1 to the rockchip rk3399 clock drivers. These clock gates were referenced by arch/arm/dts/rk3399.dtsi for vopb and vopl. The driver drivers/video/rockchip/rk3399_vop.c won't get probed without these clocks and the framebuffer does not work. --- drivers/clk/rockchip/clk_rk3399.c | 11 +++++++++++ 1 file changed, 11 insertions(+) diff --git a/drivers/clk/rockchip/clk_rk3399.c b/drivers/clk/rockchip/clk_rk3399.c index 865b80cc0f..a3628d4a4c 100644 --- a/drivers/clk/rockchip/clk_rk3399.c +++ b/drivers/clk/rockchip/clk_rk3399.c @@ -923,6 +923,11 @@ static ulong rk3399_clk_get_rate(struct clk *clk) case DCLK_VOP0: case DCLK_VOP1: break; + case ACLK_VOP0: + case ACLK_VOP1: + case HCLK_VOP0: + case HCLK_VOP1: + break; case PCLK_EFUSE1024NS: break; case SCLK_SARADC: @@ -994,6 +999,12 @@ static ulong rk3399_clk_set_rate(struct clk *clk, ulong rate) case DCLK_VOP1: ret = rk3399_vop_set_clk(priv->cru, clk->id, rate); break; + case ACLK_VOP0: + case ACLK_VOP1: + case HCLK_VOP0: + case HCLK_VOP1: + /* clock gates are enabled by default */ + break; case SCLK_DDRCLK: ret = rk3399_ddr_set_clk(priv->cru, rate); break; -- 2.25.1

[PATCH 000/108] RFC: dm: Add programatic generation of ACPI tables
by Simon Glass 14 Mar '20

14 Mar '20

At present on x86 U-Boot supports creating ACPI (Advanced Configuration and Power Interface) tables using the Intel ACPI Source Language (ASL) compiler. This is good enough for basic operation but some devices need to add their information dynamically at runtime. An example is a device that needs to report its enable GPIO. This is described in the device tree, so we want to add code in the driver to convert that device-tree description into an ACPI description for use on Linux. This series adds support for generation of ACPI tables and fragments by devices. The core support is built into driver model. Several files are brought over from coreboot to do the actual generation. As an example of using this new feature, chromebook_coral is updated to write out a wide array of ACPI tables including DSDT and SSDT. This initial version of the series lays out the general approach. More work is needed to figure out the difference between CONFIG_ACPIGEN and CONFIG_GENERATE_ACPI_TABLE with respect to what is built.

[PATCH] qemu: arm: Scan the pci bus in board_init

Scan the pci bus in board_init routine before scanning the virtio devices. This enumerates all the virtio devices, including devices found on the pci bus.

[PATCH 0/2] cli: allow verbatim character entry with CTRL-v
by Heinrich Schuchardt 14 Mar '20

14 Mar '20

Up to now the U-Boot console does not allow to add a control character to the line buffer. In Bash and Vim we can use CTRL-v for this purpose. Add support for CTRL-v for verbatim entry of characters.

[PATCH v3 0/9] am57xx: Implement Android 10 boot flow
by Sam Protsenko 14 Mar '20

14 Mar '20

Android 10 brings a lot of new requirements for bootloaders: [1]. This patch series attempts to implement such a boot process on BeagleBoard X15 platform. Some common code is added too, which can be reused later for other platforms (see "abootimg" command and associated C API). This patch series must be applied on top of these recently sent patches by Eugeniu: [PATCH 0/3] cmd: dtimg: Rename to adtimg and refactor usage style Changes in v3: - rename command to "abootimg" (requested by Simon Glass) - rework command interface (as discussed with Eugeniu) - add command documentation - address other comments [1] https://source.android.com/devices/bootloader Sam Protsenko (9): image: android: Add functions for handling dtb field image: android: Add routine to get dtbo params cmd: abootimg: Add abootimg command doc: android: Add documentation for Android Boot Image test/py: android: Add test for abootimg configs: am57xx_evm: Enable Android commands env: ti: boot: Respect slot_suffix in AVB commands env: ti: boot: Boot Android with dynamic partitions arm: ti: boot: Use correct dtb and dtbo on Android boot cmd/Kconfig | 10 + cmd/Makefile | 1 + cmd/abootimg.c | 242 +++++++++++++++++ common/Makefile | 2 +- common/image-android.c | 275 ++++++++++++++++++++ configs/am57xx_evm_defconfig | 6 + configs/am57xx_hs_evm_defconfig | 6 + configs/am57xx_hs_evm_usb_defconfig | 6 + configs/sandbox_defconfig | 1 + doc/android/boot-image.rst | 154 +++++++++++ include/configs/ti_armv7_common.h | 7 + include/environment/ti/boot.h | 146 ++++++----- include/image.h | 6 + test/py/tests/test_android/test_abootimg.py | 159 +++++++++++ 14 files changed, 954 insertions(+), 67 deletions(-) create mode 100644 cmd/abootimg.c create mode 100644 doc/android/boot-image.rst create mode 100644 test/py/tests/test_android/test_abootimg.py -- 2.24.0

[U-Boot] `uclass_find_device_by_name` fails to find the device
by Nandor Han 14 Mar '20

14 Mar '20

Hi everybody, I've noticed that commit 4213609cc7fb78f84b2ea63f4a5691b60d01c248 changes how `uclass.c:uclass_find_device_by_name` function compares the names for finding devices. Because of this I have an issue when having a DTS and trying to find a device by name. The `lists.c:lists_bind_fdt` function will bind a device to a device node tree and use the node name as device name. ``` lists.c: int lists_bind_fdt(..) ... name = ofnode_get_name(node); ... ``` Because of this devices will end up having names like: i2c@021a0000, pfuze100@8... When using `uclass.c:uclass_find_device_by_name` to get a device, before the change, this was not an issue since `strncmp` was used with the length of the name making a call like `uclass_find_device_by_name(pfuze100)` successfully even if the device name was `pfuze100@8`. ``` if (!strncmp(dev->name, name, strlen(name))) { ``` However after the change (which I think is correct), the check fails, resulting in not finding the expected device, since the device name has also the suffix `@...` included. What's the proper fix here: 1. Changing the `lists.c:lists_bind_fdt` to drop the `@` suffix? Note: Could this be a problem when having the same node names but different addressees in DTS {e.g.foo@1, foo@2} 2. When using `uclass.c:uclass_find_device_by_name` the user should take in consideration that `@..` suffix needs to be added. Note: This could be a problem when same code is used with different DTSs. 3. Changing the comparation in `uclass.c:uclass_find_device_by_name` to ignore the part after `@` for device names. 4. What else? Regads, Nandor
