2017-12-04ARM: arch-meson: build memory banks using reported memory from registersNeil Armstrong
As discussed at [1], the Amlogic Meson GX SoCs can embed a BL31 firmware and a secondary BL32 firmware. Since mid-2017, the reserved memory address of the BL31 firmware was moved and grown for security reasons. But mainline U-Boot and Linux has the old address and size fixed. These SoCs have a register interface to get the two firmware reserved memory start and sizes. This patch adds a dynamic reservation of the memory zones in the device tree bootmem reserved memory zone used by the kernel in early boot. To be complete, the memory zones are also added to the EFI reserved zones. Depends on patchset "Add support for Amlogic GXL Based SBCs" at [2].

2017-11-17arm: add initial support for Amlogic P212 based on Meson GXL familyNeil Armstrong
This adds platform code for the Amlogic P212 reference board based on a Meson GXL (S905X) SoC with the Meson GXL configuration. This initial submission only supports UART and MMC/SDCard, support for the internal Ethernet PHY in Work In Progress.
