| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Tegra's drive group registers have a remarkably inconsistent layout. The current U-Boot driver doesn't take this into account at all. Add a comment to describe the issue, so at least anyone debugging the driver will be aware of this. To solve this, we'd need to add a per-drive-group data structure describing the layout for the individual register. Since we don't set up too many drive groups in U-Boot at present, this hopefully isn't causing too much practical issue. Still, we probably need to fix this sometime. Wth Tegra210, the register layout becomes almost entirely consistent, so this problem partially solves itself over time.

One example is configuring the ARM architectural timer's CNTFRQ register. We could support this in one of two ways: 1) Compile twice, once for secure mode (in which case anything goes) and once for non-secure mode (in which case certain actions are disabled). This complicates things, since everyone needs to keep track of different U-Boot binaries for different situations. 2) Detect NS mode at run-time, and optionally skip any impossible actions. This has the advantage of a single U-Boot binary working in all cases. (2) is not possible on ARM in general, since there's no architectural way to detect secure-vs-non-secure. However, there is a Tegra-specific way to detect this. This patches uses that feature to detect secure vs. NS mode on Tegra, and uses that to: * Skip the ARM arch timer initialization. * Set/clear an environment variable so that boot scripts can take different action depending on which mode the CPU is in. This might be something like: if CPU is secure: load secure monitor code into RAM. boot secure monitor. secure monitor will restart (a new copy of) U-Boot in NS mode. else: execute normal boot process Signed-off-by: Stephen Warren <swarren@nvidia.com> Signed-off-by: Tom Warren <twarren@nvidia.com>

| * ARM: tegra: support large RAM sizesStephen Warren2015-03-04-1/+21
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Some systems have so much RAM that the end of RAM is beyond 4GB. An example would be a Tegra124 system (where RAM starts at 2GB physical) that has more than 2GB of RAM. In this case, we want gd->ram_size to represent the actual RAM size, so that the actual RAM size is passed to the OS. This is useful if the OS implements LPAE, and can actually use the "extra" RAM. However, we can't use get_ram_size() to verify the actual amount of RAM present on such systems, since some of the RAM can't be accesses, which confuses that function. Avoid calling get_ram_size() when the RAM size is too large for it to work correctly. It's never actually needed anyway, since there's no reason for the BCT to report the wrong RAM size. In systems with >=4GB RAM, we still need to clip the reported RAM size since U-Boot uses a 32-bit variable to represent the RAM size in bytes.
