[ros-diffs] [ros-arm-bringup] 34444: - Do NOT prepend _ to ARM entrypoints. - Because of some ridiculously stupid design in LD, it seems if it cannot find a given entrypoint, it SILENTLY ASSUMES you meant "Hi LD, please use my base address as my entrypoint". - As such, all our drivers were linked with the start address as the base address... for the RAMDisk driver, this ended up being RamdiskAddDevice. - When we started implementing RamdiskAddDevice, noticed that DriverEntry wasn't actually getting called.

Log:
- Do NOT prepend _ to ARM entrypoints.
- Because of some ridiculously stupid design in LD, it seems if it cannot find a given
entrypoint, it SILENTLY ASSUMES you meant "Hi LD, please use my base address as my
entrypoint".
- As such, all our drivers were linked with the start address as the base address... for
the RAMDisk driver, this ended up being RamdiskAddDevice.
- When we started implementing RamdiskAddDevice, noticed that DriverEntry wasn't
actually getting called. Adding debug prints changed which function was called.
- Wasted a week, thanks LD.
