2015-11-12ARM: tegra: rename dummy XUSB padctl implementationStephen Warren
A future patch will soon move some of the XUSB padctl code into a common file in arch/arm/mach-tegra. Rename the existing dummy XUSB padctl file to avoid conflicting with that, or being confusing.

2015-11-12ARM: tegra: enable PCI support of p2371-2180Stephen Warren
p2371-2180 has two PCI ports; a regular x4 slot and a x1 M.2 slot. This patch adds the relevant DT to enable the PCI controller and configure the XUSB padctl pin muxing, and code to turn on the PCI power and enable PCI features in U-Boot. I have only tested the x4 slot. Signed-off-by: Stephen Warren <swarren@nvidia.com> Signed-off-by: Tom Warren <twarren@nvidia.com>
2015-11-12ARM: tegra: add PCI to Tegra210 SoC DTStephen Warren
Tegra210's PCI controller is largely identical to Tegra124, and hence shares the same binding. However, it has a unique compatible value due to the existence of at least one new HW bug that would prevent any driver for a previous HW version from operating correctly.

Implement the procedure that the TRM mandates to initialize PLLREFE and PLLE. This makes the PLL actually lock. Note that this section of the TRM is being cleaned up to remove some confusion.

2015-11-10ARM: tegra: enable CONFIG_SYS_NONCACHED_MEMORY everywhereStephen Warren

2015-11-10ARM: tegra: add custom MMU setup on ARMv8Stephen Warren
This sets up a fine-grained page table, which is a requirement for noncached_init() to operate correctly. MMU setup code currently exists in a number of places: - A version in the core ARMv8 support code that sets up page tables that use very large block sizes that CONFIG_SYS_NONCACHED_MEMORY doesn't support. - Enhanced versions for fsl-lsch3 and zynmq that set up finer grained page tables. Ideally, rather than duplicating the MMU setup code yet again this patch would instead consolidate all the different routines into the core ARMv8 code so that it supported all use-cases. However, this will require significant effort since there appear to be a number of discrepancies[1] between different versions of the code, and between the defines/values by some copies of the MMU setup code use and the architectural MMU documentation. Some reverse engineering will be required to determine the intent of the current code. [1] For example, in the core ARMv8 MMU setup code, three defines named TCR_EL[123]_IPS_BITS exist, but only one of them sets the IPS field and the others set a different field (T1SZ) in the page tables. As far as I can tell so far, there should be no need to set different values per exception level nor to modify the T1SZ field at all, since TTBR1 shouldn't be enabled anyway. Another example is inconsistent values for *_VA_BITS between the current core ARMv8 MMU setup code and the various SoC- specific MMU setup code. Another example is that asm/armv8/mmu.h's value for SECTION_SHIFT doesn't match asm/system.h's MMU_SECTION_SHIFT; research is needed to determine which code relies on which of those values and why, and whether fixing the incorrect value will cause any regression.

2015-11-10armv8: allow custom MMU setup routines on ARMv8Stephen Warren
In order for noncached_init() to operate correctly, SoCs must set up a custom page table with fine-grained (2MiB) sections, which can be configured from noncached_init(). This is currently performed by arch/arm/cpu/armv8/{fsl-lsch3,zynqmp}/cpu.c by cut/pasting and re-implementing mmu_setup, enable_caches(), etc. There are some other reasons for the duplication there though, such as enabling icache early, and enabling dcaching earlier with a different configuration. This change makes mmu_setup() a weak implementation, so that the MMU setup code can be replaced without having to duplicate other code that calls it. Signed-off-by: Stephen Warren <swarren@nvidia.com>
2015-11-10armv8: enable compilation with CONFIG_SYS_NONCACHED_MEMORYStephen Warren
The implementation of noncached_init() uses define MMU_SECTION_SIZE. Define this on ARM64. Move the prototype of noncached_{init,alloc}() to a location that doesn't depend on !defined(CONFIG_ARM64). Note that noncached_init() calls mmu_set_region_dcache_behaviour() which relies on something having set up translation tables with 2MB block size. The core ARMv8 MMU setup code does not do this by default, but currently relies on SoC specific MMU setup code. Be aware of this before enabling this feature on your platform!

2015-11-09Replace "extern inline" with "static inline"Måns Rullgård
A number of headers define functions as "extern inline" which is causing problems with gcc5. The reason is that starting with version 5.1, gcc defaults to the standard C99 semantics for the inline keyword. Under the traditional GNU inline semantics, an "extern inline" function would never create an external definition, the same as inline *without* extern in C99. In C99, and "extern inline" definition is simply an external definition with an inline hint. In short, the meanings of inline with and without extern are swapped between GNU and C99. The upshot is that all these definitions in header files create an external definition wherever those headers are included, resulting in multiple definition errors at link time. Changing all these functions to "static inline" fixes the problem since this works as desired in all gcc versions. Although the semantics are slightly different (a static inline definition may result in an actual function being emitted), it works as intended in practice. This patch also removes extern prototype declarations for the changed functions where they existed. Signed-off-by: Mans Rullgard <mans@mansr.com>
