[v4] ArmPkg/ArmMmuLib: rewrite and improve cache handling with MMU off

[edk2-devel] [PATCH v4 0/2] ArmPkg/ArmMmuLib: rewrite and improve cache handling with MMU off

Posted by Ard Biesheuvel 4 years, 1 month ago

I finally got fed up with the state of the AArch64 MMU handling code, and
decided to rewrite it before rebasing the cache invalidation fix onto
it.

Changes since v3:
- move code for better diffing
- free allocated page tables on failure if it is safe to do so
- some minor style tweaks
- add Leif's ack to #2

Ard Biesheuvel (2):
  ArmPkg/ArmMmuLib AARCH64: rewrite page table code
  ArmPkg/ArmMmuLib AARCH64: invalidate page tables before populating
    them
