platform: generic: Initialize console before other drivers

2024-12-21T12:51:50Z

Initialize serial drivers first, so messages printed by other drivers do not need to use the early console buffer. Suggested-by: Anup Patel Signed-off-by: Samuel Holland Reviewed-by: Anup Patel

lib: sbi_pmu: PMU raw event v2 support

2024-12-02T04:22:04Z

As per the updated ISA specification and SBI PMU v3.0, lower 56 bits are available for the platform to implement mhpmeventX encoding. Implement the PMU raw event V2 support defined in SBI v3.0 which allows more bits for platforms to encode the raw events. Signed-off-by: Atish Patra Reviewed-by: Anup Patel

treewide: Make carray arrays const and NULL-terminated

2024-11-28T11:39:17Z

This allows the compiler to generate significantly better code, because it does not have to maintain either the loop counter or loop limit. Plus there are half as many symbols to relocate. This also simplifies passing carray arrays to helper functions. Signed-off-by: Samuel Holland Reviewed-by: Anup Patel

platform: Drop irqchip warm init and exit hooks

2024-11-28T06:16:36Z

Now that driver lifecycle is managed from within the SBI irqchip core, platforms need only to initialize the driver once during cold init. Remove the remaining platform hooks that are no longer used. Signed-off-by: Samuel Holland Reviewed-by: Anup Patel

platform: Drop IPI warm init and exit hooks

2024-11-11T12:51:04Z

Now that the SBI IPI core clears IPIs at warm boot in a generic way, none of the drivers or platforms use these hooks, and we can remove them. Platforms need only to initialize the driver once during cold init. If other hooks are needed in the future, they can be added to struct sbi_ipi_device.

platform: introduce DT-based configurable heap size

2024-11-11T12:18:45Z

The default heap size will work for most platforms, but for some special platforms, the heap is too small to hold all the information or is too big so that it take too much ram. Introduce configurable heap should solve this problem and make all generic platforms happy. Add DT-based heap-size for the generic platform.
