Subject: [PATCH] firmware: Do not allow harts with different XLEN to boot
|
||||
|
||||
OpenSBI is built separately for RV32/RV64. Thus, it shouldn't try to boot
|
||||
harts with a different XLEN compared to what it is compiled with.
|
||||
|
||||
This patch fixes the issue observed in beagleV which has two U74(RV64) and
|
||||
one E24 (RV32) harts.
