[c-nsp] 2951 memory upgrade to 2GB/Boot loader

[Jay Nakamura]

Just wanted to mention that someone at Cisco saw my post and gotten it
taken care of pretty quickly.

Conclusion,
- One 2GB DIMM in slot 0 is supported on 2951.
- ROMMON upgrade is not necessary.

Which leaves me with bad batch of DIMM.

Thanks!

Memory upgrades on the Cisco 2951 can involve the increase in the density of that single DIMM or a combination of DIMMs with BOTH slots populated. The Cisco 2951 allows the use of asymmetric densities of DRAM in both slots.
