Subject: [PATCH 67/78] gdbstub: Add helper function to unregister GDB register
|
|
space
|
|
|
|
Add common function to help unregister the GDB register space. This shall be
|
|
done in context to the CPU unrealization.
|
|
|
|
Note: These are common functions exported to arch specific code. For example,
|
|
for ARM this code is being referred in associated arch specific patch-set:
