* Fixed semihosting for ARM when heapinfo not provided by debugger.David Hoover2016-04-211-1/+3

* Initializing TTBR0 to inner/outer WBJiong Wang2016-03-261-1/+10
| | | | | | | | | | | | | | | | | | | | | While running tests on internal systems, we identified an issue in the startup code for newlib on AArch32 systems with Multiprocessor Extensions to the architecture. The issue is we were configuring page table flags to be Inner cacheable/Outer non-cacheable, while for at least architectures with Multiprocessor Extension, we'd configure it to Inner/Outer write-back, no write-allocate, and cacheable. The attached patch fixes this, and no regression on arm-none-eabi bare-metal tests. Adopted suggestion given by Richard offline to avoid using jump. libgloss/ * arm/cpu-init/rdimon-aem.S: Set TTBR0 to inner/outer cacheable WB, and no allocate on WB for arch with multiprocessor extension.
