Hello build bot (Jenkins),
I'd like you to reexamine a change. Please visit

nb/amd/pi,sr5650: Remove unnecessary memory allocation
add_ivrs_device_entries() is a recursive function, and each recursive call is passed a pointer to a root_level variable declared outside the function. In an attempt to make the function self-contained, the initial call is made with the root_level pointer set to NULL, and then the function attempts to detect this and allocate a root_level variable for the rest of the calls. This makes memory management very tricky - for example, the pi code incorrectly attempts to free the root_level variable at the end of *each* recursive call, which only avoids being a double-free because free() in coreboot is currently a no-op. Let's keep life simple and declare root_level as a local variable outside the first function call instead.
