From 869d40bdfca05e67ac6979535c485ab2c8fccc63 Mon Sep 17 00:00:00 2001 From: Sunil V L Date: Fri, 27 May 2022 10:47:39 +0530 Subject: [PATCH] riscv: cpu_ops_sbi: Add 64bit hartid support on RV64 The hartid can be a 64bit value on RV64 platforms. Modify the hartid variable type to unsigned long so that it can hold 64bit value on RV64 platforms.
