In the presence of potentially fragemented memory, we cannot hard-code
addresses into environment variables such as kernel_addr_r. Instead, we
must calculate those addresses at run-time based on available memory
locations. Implement the code to perform such runtime

arch_lmb_reserve() currently assumes that the stack pointer is within DRAM
bank 0. This is not necessarily true. Enhance the code to search through
DRAM banks until the bank that does contain SP is found, and then reserve
the tail of that bank.

From: Stephen Warren
Tegra186 currently restricts its DRAM usage to entries in the /memory node
in the DTB passed to it. However, the MMU configuration always maps the
entire first 2GB of RAM. This could allow the CPU to speculatively access
RAM that isn't part of the in-use banks. This

On this platform, there may be up to 1024 unusable chunks of memory.
Increase CONFIG_NR_DRAM_BANKS so that U-Boot can remember all the banks
required to represent such fragmented memory.

In the future, the list of DRAM regions passed to U-Boot in the DTB may
be quite long and fragmented. Due to this, U-Boot must search through the
regions to find the best region to relocate into, rather than relying on
the current assumption that the top of bank 0 is a
From: Stephen Warren
Apply a few small fixes for the DTB /memory node parsing from NVIDIA's
downstream U-Boot:
- Allow arbitrary number of DRAM banks.
- Correctly calculate the number of DRAM banks.
- Clip PCIe memory in the same way as U-Boot CPU memory use.
