Represent all available RAM in either one or two banks. The first bank
describes any RAM below 4GB. The second bank describes any RAM above 4GB.

This split is driven by the following requirements:

  existence of a carve-out at the end of RAM below 4GB can only be
  represented using multiple banks, since usable RAM is not contiguous.

Stephen Warren [Fri, 7 Aug 2015 22:12:44 +0000 (16:12 -0600)]
ARM: tegra: query_sdram_size() cleanup

The return value of query_sdram_size() is assigned directly to
gd->ram_size in dram_init(). Adjust the return type to match the field
it's assigned to. This has the beneficial effect that on 64-bit systems,
the return value can correctly represent large RAM sizes over 4GB.

For similar reasons, change the type of variable size_bytes in the same
way.

query_sdram_size() would previously clip the detected RAM size to at most
just under 4GB in all cases, since on 32-bit systems, larger values could
not be represented. Disable this feature on 64-bit systems since the
representation restriction does not exist.

On 64-bit systems, never call get_ram_size() to validate the detected/
calculated RAM size. On any system with a secure OS/... carve-out, RAM
may not have a single contiguous usable area, and this can confuse
get_ram_size(). Ideally, we'd make this call conditional upon some other
flag that indicates specifically that a carve-out is actually in use. At
present, building for a 64-bit system is the best indication we have of
this fact. In fact, the call to get_ram_size() is not useful by the time
U-Boot runs on any system, since U-Boot (and potentially much other early
boot software) always runs from RAM on Tegra, so any mistakes in memory
controller register programming will already have manifested themselves
and prevented U-Boot from running to this point. In the future, we may
simply delete the call to get_ram_size() in all cases.

ARM: tegra: move kernel_addr_r on T210

The new value is the most likely value where the kernel wants to end up
at run-time. Selecting this value as the load address likely avoids the
need to copy the kernel image from the actual load address to the desired
load address. Note that this isn't guaranteed since the kernel may wish
to run at an arbitrary location. In that case, U-Boot will still relocate
the image according to its wishes; this change is a performance
optimization, not a hard-coding of the final image location.
