FIRM-packages

819:

The only change under RomFS "/nx/" was package2. Filesize is same as before.

Kernel was updated. FIRM-sysmodules were not updated.

Kernel

• The mmutable init code was updated.
  • Some table addrs were updated.
  • For the first DRAM mapping loop, the descriptor-ORR value now has bitmask 0x40000000000000 set. This is for TTBR0 vmem 0x80000000. This enables usermode XN for the temporary DRAM mapping only used during kernel boot.
  • The descriptor ORR-value for this now has bitmask 0x3000000000000000 set: *(addr+0xf8) = tableaddr | <orrvalue>;//(level2 pagetable descriptor for vmem 0xFFFFFFF7C0000000)
  • Descriptor ORR-value bitmask 0x3000000000000000 is now also set for sometable+0xfb0, +0xfc0, and othertable+0xff0.
  • Kernel .text descriptor ORR-value now has bitmask 0x40000000000000 set. This enables usermode XN for kernel .text, previously kernel .text was executable from usermode.

• The below code is probably memory-management related?
