2017-04-05sunxi: prepare for sharing MACH_SUN8I_H3 config symbolAndre Przywara

2017-04-05sunxi: DRAM: add Allwinner H5 supportAndre Przywara
The DRAM controller in the Allwinner H5 SoC is again very similar to the one in the H3 and A64. Based on the existing socid parameter, add support for this controller by reusing the bulk of the code and only deviating where needed. These new bits set or cleared here and there have been mostly found by looking at DRAM register dumps after using the H5 boot0 and comparing them to what we set in the code. So for now it's mostly unclear what those bits actually mean - hence the missing names and comments. Also add the delay line parameters taken from the boot0 and libdram disassembly. Register setup differences between H5 and H3 are courtesy of Jens Kuske. Signed-off-by: Andre Przywara <andre.przywara@arm.com> Acked-by: Maxime Ripard <maxime.ripard@free-electrons.com>
2017-04-05sunxi: Kconfig: introduce CONFIG_SUNXI_HIGH_SRAMAndre Przywara
Traditionally Allwinner SoCs have their boot ROM mapped just below 4GB, while the first SRAM region is mapped at address 0. With the extended physical memory support of the A80 this was changed, so the BROM is now at address 0 and the SRAM region starts right behind this at 64KB. This configuration seems to be called "high SRAM". Instead of enumerating the SoCs which have copied this configuration, let's call a spade a spade and introduce a Kconfig option for this setup. SoCs implementing this (A80, A64 and H5, so far), can then select this configuration. Simplify the config header definition on the way.

2017-04-05net: gmac_rockchip: Add support for the RK3399 GMACPhilipp Tomsich
The GMAC in the RK3399 is very similar to the RK3288 variant (i.e. it is a Designware GMAC core and requires similar configuration as the RK3288 to switch it to RGMII and set up the TX/RX delays for Gigabit). The key difference is that the register offsets (within the GRF block) and bit-offsets (within those registers) used to hold the configuration differ between the various RK32/33 CPUs. This change refactors the gmac_rockchip.c driver to use a function table (selected via driver_data) to factor out these differences. Each function's implementation then matches the underlying processor. Some collateral changes are needed in the definitions describing the bits and offsets in the GRF are needed to prefix each set of symbolic constants with the SoC name to avoid name clashes... and in doing so, the shifts for masks and constants have been moved into the header files for readability (and to make it easier to stay below 80 chars).

The armclk starts in slow mode (24MHz) on the rk3188, which makes the whole startup take a lot of time. We therefore want to at least move to the safe 600MHz value we can use with default pmic settings. This is also the freqency the proprietary sdram-init leaves the cpu at. For boards that have pmic control later in u-boot, we also add the option to set the maximum frequency of 1.6GHz, if they so desire.

2017-04-05rockchip: spl: RK3399: use boot0 hook to create space for SPL magicPhilipp Tomsich
The SPL binary needs to be prefixed with the boot magic ('RK33' for the RK3399) on the Rockchip platform and starts execution of the instruction word following immediately after this boot magic. This poses a challenge for AArch64 (ARMv8) binaries, as the .text section would need to start on the odd address, violating natural alignment (and potentially triggering a fault for any code that tries to access 64bit values embedded in the .text section). A quick and easy fix is to have the .text section include the 'RK33' magic and pad it with a boot0 hook to insert 4 bytes of padding at the start of the section (with the intention of having mkimage overwrite this padding with the appropriate boot magic). This avoids having to modify the linker scripts or more complex logic in mkimage.

For validating images from uboot (Such as Kernel Image), either keys from SoC fuses can be used or keys from a verified table of public keys can be used. The latter feature is called IE Key Extension Feature. For Layerscape Chasis 3 based platforms, IE table is validated by Bootrom and address of this table is written in scratch registers 13 and 14 via PBI commands. Following are the steps describing usage of this feature: 1) Verify IE Table in ISBC phase using keys stored in fuses. 2) Install IE table. (To be used across verification of multiple images stored in a static global structure.) 3) Use keys from IE table, to verify further images.
