[PATCH] arm: mach-k3: am62a7_init: Open up FSS_DAT_REG3 firewall

2023-07-02 Thread Vignesh Raghavendra
On security enforced (HS-SE) devices ROM firewalls OSPI data region3 that is present in above 64bit region. Open this up in bootloader to allow Linux to access OSPI flashes in mmap mode. Without this kernel will crash when accessing this region due to firewall violations on HS-SE devices.
