      rockchip: Disable binary generation for all SoCs. · 33218d2a
      Christoph Müllner authored
      
      
      All supported Rockchip SoCs (RK3288, RK3328, RK3368 and RK3399)
      have non-continuous memory areas in the linker script with a huge
      gap between them. This results in extremely padded binary images
      with a size of about 4 GiB.
      
      E.g. on the RK3399 we have the following memory areas (and base addresses):
      RAM (0x1000), SRAM (0xFF8C0000), and PMUSRAM (0xFF3B0000).
      
      Consumers of the TF-A project (e.g. coreboot or U-Boot) therefore
      use the ELF image instead, which has a size of a few hundred kBs.
      
      In order to prevent the generation of a huge and useless file,
      this patch disables the binary generation for all affected Rockchip
      SoCs.

      rockchip: Streamline and complete UARTn_BASE macros. · 0957b9b2
      Christoph Müllner authored
      
      
      In order to set the UART base during bootup in common code of
      plat/rockchip, we need to streamline the way the UART base addresses
      are defined and add the missing definitions and mappings.
      
      This patch does so by following the pattern UARTn_BASE, which is
      already in use on RK3399 and RK3328. The numbering itself is derived
      from the upstream Linux DTS files of the individual SoCs.

      rockchip: only include libfdt in non-coreboot cases · 4200e5aa
      Heiko Stuebner authored
      
      
      While mainline u-boot always expects to submit the devicetree
      as platform param, coreboot always uses the existing parameter
      structure. As libfdt is somewhat big, it makes sense to limit
      its inclusion to where necessary and thus only to non-coreboot
      builds.
      
      libfdt itself will get build in all cases, but only the non-
      coreboot build will actually reference and thus include it.

      rockchip: add support for rk3288 · 780e3f24
      Heiko Stuebner authored
      
      
      The rk3288 is a 4-core Cortex-A12 SoC and shares a lot of features
      with later SoCs.
      
      Working features are general non-secure mode (the gic needs special
      love for that), psci-based smp bringing cpu cores online and also
      taking them offline again, psci-based suspend (the simpler variant
      also included in the linux kernel, deeper suspend following later)
      and I was also already able to test HYP-mode and was able to boot
      a virtual kernel using kvm.
