According to table 2-3 on page 87 of Marvell's latest PXA270 Specification Update Rev. I from 2010.04.19 [1] there exists a breed of chips with a new CPU ID for PXA270M A1 stepping which our latest Colibri PXA270 V2.4A modules actually have assembled. This patch helps in correctly identifying those chips upon boot as well which then looks as follows: CPU: Marvell PXA27xM rev.

2015-03-04ti: armv7: Move SPL SDRAM init to the right place, drop unused CONFIG_SPL_STACKSimon Glass
Currently in some cases SDRAM init requires global_data to be available and soon this will not be available prior to board_init_f(). Adjust the code paths in these cases to be correct. In some cases we had the SPL stack be in DDR as we might have large stacks (due to Falcon Mode + Environment). In these cases switch to CONFIG_SPL_STACK_R. In other cases we had simply been setting CONFIG_SPL_STACK into SRAM. In these cases we no longer need to (CONFIG_SYS_INIT_SP_ADDR is used and is also in SRAM) so drop those lines.

2015-03-04arm: spl: Allow board_init_r() to run with a larger stackSimon Glass
At present SPL uses a single stack, either CONFIG_SPL_STACK or CONFIG_SYS_INIT_SP_ADDR. Since some SPL features (such as MMC and environment) require a lot of stack, some boards set CONFIG_SPL_STACK to point into SDRAM. They then set up SDRAM very early, before board_init_f(), so that the larger stack can be used. This is an abuse of lowlevel_init(). That function should only be used for essential start-up code which cannot be delayed. An example of a valid use is when only part of the SPL code is visible/executable, and the SoC must be set up so that board_init_f() can be reached. It should not be used for SDRAM init, console init, etc. Add a CONFIG_SPL_STACK_R option, which allows the stack to be moved to a new address before board_init_r() is called in SPL. The expected SPL flow (for CONFIG_SPL_FRAMEWORK) is documented in the README.

As an interim measure, remove it only if CONFIG_DM is not defined. This allows us to press ahead with driver model in SPL and allow the stragglers to catch up.

2015-03-04arm: Reduce the scope of lowlevel_init()Simon Glass
This function has grown into something of a monster. Some boards are setting up a console and DRAM here in SPL. This requires global_data which should be set up in one place (crt0.S). There is no need for SPL to use s_init() for anything since board_init_f() is called immediately afterwards. Signed-off-by: Simon Glass <sjg@chromium.org>

2015-03-04ARM: tegra: pinmux: add note re: drive group field definesStephen Warren
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.

2015-03-04ARM: tegra: support running in non-secure modeStephen Warren
When the CPU is in non-secure (NS) mode (when running U-Boot under a secure monitor), certain actions cannot be taken, since they would need to write to secure-only registers. 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>

2015-03-04ARM: tegra: support large RAM sizesStephen Warren
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.
