Added APIs to add and remove regions to the translation tables dynamically while the MMU is enabled. Only static regions are allowed to overlap other static ones (for backwards compatibility). A new private attribute (MT_DYNAMIC / MT_STATIC) has been added to flag each region as such. The dynamic mapping functionality can be enabled or disabled when compiling by setting the build option PLAT_XLAT_TABLES_DYNAMIC to 1 or 0. This can be done per-image. TLB maintenance code during dynamic table mapping and unmapping has also been added. Fixes ARM-software/tf-issues#310 Change-Id: I19e8992005c4292297a382824394490c5387aa3b Signed-off-by: Antonio Nino Diaz <antonio.ninodiaz@arm.com> |
