[U-Boot] [PATCH v3 00/19] Add Intel Arria 10 SoC support
This is the 3rd version of patchset to adds support for Intel Arria 10 SoC. This version mainly resolved comments from Marek in [v2].
This is initial patchset enables the basic support for Arria 10 and other features will come after this.
This series is working on top of “arm: socfpga: Move to using distro boot” series [1] from Dalon Westergreen.

v2 -> v3 changes: ----------------- - Drop "[PATCH v2 02/20] arm: socfpga: Update clock for Gen5" in [v2] from this A10 patch series, since it is non Arria 10 related. - Add socfpga_ prefix for exported functions in reset driver. - Check return value from wait_for_bit(). - Remove extra parenthesis around statement - Refactor cm_calc_safe_pll_numer() clock driver. - Use BIT(n) for bit shifting. - Resolved warnings and errors from checkpatch.pl.

Restructure clock manager driver in the preparation to support A10. Move the Gen5 specific code to _gen5 files. No functional change.
Change all uint32_t to u32 and change to use macro BIT(n) for bit shift.

Restructure reset manager driver in the preparation to support A10. Move the Gen5 specific code to gen5 files. Minor update in socfpga_per_reset(). No functional change.

In the reset_manager_gen5.h file, patch #02, you are still using Altera in the header and it was GPL-2.0+ license. Now you're using Intel and GPL-2.0, I'm not sure which is right, but I think it should be Intel for all new files? Let's be consistent?

reset_manager_gen5.h is moved from reset_manager.h. So, I keep its original license header for it. But, arch/arm/mach-socfpga/include/mach/misc.h is a new file. So, we use Intel license header for all new files.
