dm: crypto: Define UCLASS API for ECDSA signature verification

2021-08-16T08:49:35Z

Define a UCLASS API for verifying ECDSA signatures. Unlike UCLASS_MOD_EXP, which focuses strictly on modular exponentiation, the ECDSA class focuses on verification. This is done so that it better aligns with mach-specific implementations, such as stm32mp. Signed-off-by: Alexandru Gagniuc Reviewed-by: Patrick Delaunay

dm: core: Don't allow uclass use before ready

2021-08-08T17:27:27Z

At present it is possible to call uclass_get() before driver model is inited. In fact this happens on x86 boards which use Intel FSPv1, since mrccache_get_region() tries to get the SPI flash device very early during init. This has always been undefined behaviour. Previously it generally worked, i.e. returned an error code without crashing, because gd->uclass_root_s is zeroed and the uclass can be added despite driver model not being ready, due to the way lists are implemented. With the change to use a gd->uclass_root pointer, this no-longer works. For example, it causes a hang on minnowmax. Fix this by adding a check that driver model is ready when uclass_get() is called. This function is called in the process of locating any device, so it is a good place to add the check. This fixes booting on minnowmax.

dm: migrate the dm_warn to use the log macro

2021-08-08T17:27:27Z

Migrate the dm_warn function to log macro with LOGC_DM category and LOGL_WARNING level. This macro allows filtering with log command and allows output on all log backend. Signed-off-by: Patrick Delaunay Reviewed-by: Simon Glass

reboot-mode: add support for reboot mode control

2021-07-23T14:16:39Z

A new driver uclass is created to handle the reboot mode control. The new uclass driver is updating an environment variable with the configured reboot mode. The mode is extracted from a map provided at initialization time. The map contains a list of modes and associated ids. Signed-off-by: Nandor Han Reviewed-by: Simon Glass

cmd: pinmux: update result of do_status

2021-07-23T11:13:25Z

Update the result of do_status and always returns a CMD_RET_ value (-ENOSYS was a possible result of show_pinmux). This patch also adds pincontrol name in error messages (dev->name) and treats correctly the status sub command when pin-controller device is not selected.

remove struct uclass_driver::ops

2021-07-06T16:38:03Z

Each _device_ belonging to a given uclass of course has its own ->ops, of a type determined by and known to the uclass. However, no instance of a uclass_driver seems to populate ->ops, and the only reference to it in code is this relocation. Moreover, it's not really clear what could sensibly be assigned; it would have to be some "struct uclass_ops *" providing a set of methods for the core to call on that particular uclass, but should the need for that ever arise, it would be better to have a member of that particular type instead of void*.
