soc/tegra: Add efuse driver for Tegra

2014-07-17T12:36:01+00:00

Implement fuse driver for Tegra20, Tegra30, Tegra114 and Tegra124. This replaces functionality previously provided in arch/arm/mach-tegra, which is removed in this patch. While at it, move the only user of the global tegra_revision variable over to tegra_sku_info.revision and export tegra_fuse_readl() to allow drivers to read calibration fuses.

ARM: tegra: move fuse exports to soc/tegra/fuse.h

2014-07-17T12:32:51+00:00

All fuse related functionality will move to a driver in the following patches. To prepare for this, export all the required functionality in a global header file and move all users of fuse.h to soc/tegra/fuse.h. While we're at it, remove tegra_bct_strapping, as its only user was removed in Commit a7cbe92cef27 ("ARM: tegra: remove tegra EMC scaling driver").

ARM: tegra: Use a function to get the chip ID

2014-07-17T11:36:41+00:00

Instead of using a simple variable access to get at the Tegra chip ID, use a function so that we can run additional code. This can be used to determine where the chip ID is being accessed without being available. That in turn will be handy for resolving boot sequence dependencies in order to convert more code to regular initcalls rather than a sequence fixed by Tegra SoC setup code.

ARM: tegra: add Tegra124 SoC support

2013-10-18T22:28:07+00:00

Add Tegra124 SoC support that base on CortexA15MP Core. And enable the SMP function that can re-use the same procedure with Tegra114. Signed-off-by: Joseph Lo Signed-off-by: Stephen Warren

ARM: tegra: add an assembly marco to check Tegra SoC ID

2013-05-22T21:19:21+00:00

There are some Tegra SoC ID checking code around the low level assembly code. Adding a marco to replace them. For the single image to support all the Tegra series, we may also need the marco in other common code. So we make it become a marco for the usage.
