[U-Boot] [PATCH] riscv: fu540: enable SMP
Hart 0 on the SiFive FU540 is meant for monitoring tasks. It is a E51 core, whereas all other cores are U54 cores. Select hart 1 as the main hart to run U-Boot.
Signed-off-by: Lukas Auer lukas.auer@aisec.fraunhofer.de --- This patch depends on the SMP support [1] and the SiFive FU540 support patch series [2]. I have submitted it independently from the SMP support patch series to allow the series to be merged independently from the SiFive FU540 support patch series.

It will be better if we can get rid off MAIN_HART config option. Otherwise, looks good to me.

Thanks for your review, Anup!
I will update the patch to remove MAIN_HART together with the next version of the SMP series.
Thanks, Lukas
