Subject: [PATCH v2 0/2] bcm4908: Fix secondary CPU initialization

Hello list,

This is v2 of my previous patch [1] for resolving a problem preventing
secondary CPU(s) from coming up on bcm4908. After some discussion, I decided to
try dropping the reserved memory region from 64K to only 4K. Looks like it
works!

Changes v1->v2:
- Reduce 64K reserved region to 4K
- Style change to the `reg` property to use hex instead of decimal
- Slight rephrasing to the commit message
- Add a new patch that also moves the `cpu-release-addr` into this reserved
  memory region

Cheers,
Sam
