bootcount: add a new driver with syscon as backend

2021-08-22T09:04:52+00:00

The driver will use a syscon regmap as backend and supports both 16 and 32 size value. The value will be stored in the CPU's endianness. Signed-off-by: Nandor Han Reviewed-by: Simon Glass

dtoc: Support widening a bool value

2021-08-01T15:05:24+00:00

At present if we see 'ranges' property (with no value) we assume it is a boolean, as per the devicetree spec. But another node may define 'ranges' with a value, forcing us to widen it to an int array. At present this is not supported and causes an error. Fix this and add some test cases.

sandbox: Reduce keyed autoboot delay

2021-08-01T15:05:24+00:00

The autoboot tests are a recent addition to U-Boot, providing much-needed coverage in this area. A side effect of the keyed autoboot test is that this feature is enabled in sandbox always. This changes the autoboot prompt and confuses the pytests. Some tests become slower, for example the vboot tests take about 27s now instead of 3s. We don't actually need this feature enabled to be able to run the tests. Add a switch to allow sandbox to turn it on and off as needed. Use this in the one test that needs it. Add a command-line flag in case this is desired in normal use. Signed-off-by: Simon Glass Fixes: 25c8b9f298e ("test: add first autoboot unit tests") Reviewed-by: Steffen Jaeckel

reboot-mode: read the boot mode from RTC memory

2021-07-23T14:16:39+00:00

RTC devices could provide battery-backed memory that can be used for storing the reboot mode magic value. Add a new reboot-mode back-end that uses RTC to store the reboot-mode magic value. The driver also supports both endianness modes. Signed-off-by: Nandor Han Reviewed-by: Simon Glass

reboot-mode: read the boot mode from GPIOs status

2021-07-23T14:16:39+00:00

A use case for controlling the boot mode is when the user wants to control the device boot by pushing a button without needing to go in user-space. Add a new backed for reboot mode where GPIOs are used to control the reboot-mode. The driver is able to scan a predefined list of GPIOs and return the magic value. Having the modes associated with the magic value generated based on the GPIO values, allows the reboot mode uclass to select the proper mode. Signed-off-by: Nandor Han Reviewed-by: Simon Glass

sandbox: don't set SA_NODEFER in signal handler

2021-07-21T16:27:35+00:00

The sandbox can handle signals. Due to a damaged global data pointer additional exceptions in the signal handler may occur leading to an endless loop. In this case leave the handling of the secondary exception to the operating system. Signed-off-by: Heinrich Schuchardt Reviewed-by: Simon Glass

sandbox: mmc: Support fixed MMC devices

2021-07-21T16:27:35+00:00

Add support for reading devicetree flags for MMC devices. With this we can distinguish between fixed and removable drives. Note that this information is only available when the device is probed, not when it is bound, since it is read in the of_to_plat() method. This could be changed if needed later.

sandbox: Use hinting with the display

2021-07-21T16:27:34+00:00

SDL provides a hinting feature which provides a higher-quality image with the double-display option (-K). Enable it. Signed-off-by: Simon Glass

sandbox: Add work-around for SDL2 display

2021-07-21T16:27:34+00:00

At present the display does not show on some machines, e.g. Ubunutu 20.04 but the reason is unknown. Add a work-around until this can be determined. Also include more error checking just in case. Signed-off-by: Simon Glass

sandbox: Support executables for more phases

2021-07-21T16:27:34+00:00

The SPL header has a function for obtaining the phase in capital letters, e.g. 'SPL'. Add one for lower-case also, as used by sandbox. Use this to generalise the sandbox logic for determining the filename of the next sandbox executable. This can provide support for VPL. Signed-off-by: Simon Glass
