2022-03-10event: Convert arch_cpu_init_dm() to use eventsSimon Glass1-1/+2
Instead of a special function, send an event after driver model is inited and adjust the boards which use this function. Signed-off-by: Simon Glass <sjg@chromium.org>
2021-02-02common: Drop asm/global_data.h from common headerSimon Glass1-0/+1
Move this out of the common header and include it only where needed. In a number of cases this requires adding "struct udevice;" to avoid adding another large header or in other cases replacing / adding missing header files that had been pulled in, very indirectly. Finally, we have a few cases where we did not need to include <asm/global_data.h> at all, so remove that include.

2020-08-14riscv: Call spl_board_init_f() in the generic SPL board_init_f()Bin Meng1-0/+9
The generic SPL version of board_init_f() should give a call to board specific codes to initialize board in the SPL phase.

2020-04-23riscv: Introduce SPL_SMP Kconfig option for U-Boot SPLBin Meng1-1/+1
With SBI v0.2 HSM extension, only a single hart need to boot and enter operating system. The booting hart can bring up secondary harts one by one afterwards. For U-Boot running in SPL, SMP can be turned on, while in U-Boot proper, SMP can be optionally turned off if using SBI v0.2 HSM. Introduce a new SPL_SMP Kconfig option to support this.

2020-01-17common: Move hang() to the same header as panic()Simon Glass1-0/+1
At present panic() is in the vsprintf.h header file. That does not seem like an obvious choice for hang(), even though it relates to panic(). So let's put hang() in its own header.

2019-12-10riscv: add option to wait for ack from secondary harts in smp functionsLukas Auer1-1/+1
Add a wait option to smp_call_function() to wait for the secondary harts to acknowledge the call-function request. The request is considered to be acknowledged once each secondary hart has cleared the corresponding IPI. As part of the call-function request, the secondary harts invalidate the instruction cache after clearing the IPI. This adds a delay between acknowledgment (clear IPI) and fulfillment (call function) of the request. We want to use the acknowledgment to be able to judge when the request has been completed. Remove the delay by clearing the IPI after cache invalidation and just before calling the function from the request.

2019-08-26riscv: add SPL supportLukas Auer1-0/+48
U-Boot SPL on the generic RISC-V CPU supports two boot flows, directly jumping to the image and via OpenSBI firmware. In the first case, both U-Boot SPL and proper must be compiled to run in the same privilege mode. Using OpenSBI firmware, U-Boot SPL must be compiled for machine mode and U-Boot proper for supervisor mode. To be able to use SPL, boards have to provide a supported SPL boot device.
