Subject: [PATCH] hw/armv7m_nvic: Correctly register GIC region when setting up
|
|
NVIC
|
|
|
|
When setting up the NVIC memory regions the memory range
|
|
0x100..0xcff is aliased to an IO memory region that belongs
|
|
to the ARM GIC. This aliased region should be added to the
|
|
NVIC memory container, but the actual GIC IO memory region
|
|
was being added instead. This mixup was causing the wrong
|
|
IO memory access functions to be called when accessing parts
|
|
of the NVIC memory.
