* ARM: tegra: represent RAM in 1 or 2 banksStephen Warren2015-08-132-15/+107
| | | | | | | | | | | | | | | | | | | | | 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: - The NVIDIA L4T kernel requires separate entries in the DT /memory/reg property for memory below and above the 4GB boundary. The layout of that DT property is directly driven by the entries in the U-Boot bank array. - On systems with RAM beyond a physical address of 4GB, the potential 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. While making this change, add a lot more comments re: how and why RAM is represented in banks, and implement a few more "semantic" functions that define (and perhaps later detect at run-time) the size of any carve-out.

* ARM: tegra: query_sdram_size() cleanupStephen Warren2015-08-131-4/+10
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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. Signed-off-by: Stephen Warren <swarren@nvidia.com> Signed-off-by: Tom Warren <twarren@nvidia.com>
* ARM: tegra: move kernel_addr_r on T210Stephen Warren2015-08-131-1/+1
| | | | | | | | | | | | | | 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.

| | | | | | | | | | | | | | | | | | The Colibri T20's PMIC enters a sleep mode on low supply voltage < 3.0V ±2.5% (2.92...3.08V).

A long positive pulse on the PMICs resume pin also reboots the system but this pin is only accessible as a test point on the module.
