Note that certain settings do not reflect reality yet. They will be updated as support improves. Signed-off-by: Gerard Marull-Paretas <gerard@teslabs.com>
Right now build system expects OpenOCD to always be available. This needs to be fixed: OpenOCD is not the only programming tool in this world! Signed-off-by: Gerard Marull-Paretas <gerard@teslabs.com>

Similar to some STM32 families, assume CM4F for now. This allows us to boot. The FreeRTOS port needs a bit of love. Signed-off-by: Gerard Marull-Paretas <gerard@teslabs.com>

Add stubs for non-implemented drivers, so that we can still build and run on SF32LB52 platforms. Signed-off-by: Gerard Marull-Paretas <gerard@teslabs.com>

As of today, SF32LB needs to run clock configuration at a very early stage, otherwise things like SystemCoreClock (used by FreeRTOS to configure the correct Systick rate), will be wrong and lead to all sorts of weird behaviors. I think it should not affect other platforms, only some seem to configure SPI slave for FPGA at that step. Signed-off-by: Gerard Marull-Paretas <gerard@teslabs.com>

Adjust MPU driver so that it is kind of functional on ARMv8 MPU. However, memory layout code relies on implementation details of the ARMv7 MPU which are not available, so the code actually needs lots of love to find a better solution to this mess. Also, SF32LB has some extra MPU requirements that need more adjustments. Summarizing, MPU is enabled but in SiFli HAL glue code (system_bf0_ap.c), but obviously not respecting any of the original PebbleOS memory layouts (e.g. all RAM is RWX by anyone).
