2019-02-28spl: add debug print for early malloc usageSimon Goldschmidt
To find out how big the early malloc heap must be in SPL, add a debug print statement that dumps its usage before switching to relocated heap in spl_relocate_stack_gd() via CONFIG_SPL_STACK_R_MALLOC_SIMPLE_LEN. Signed-off-by: Simon Goldschmidt <simon.k.r.goldschmidt@gmail.com>
2019-02-28kbuild: fix DTB .cmd source variableStephen Warren
*.dts are processed using a custom command, then the C pre-processor is run on them, then they are compiled using dtc. Thus, the dependency files generated by both cpp and dtc reference a temporary file name rather than the actual source file. While this information isn't used for any purpose by the build system, and hence this causes no functional issue, it does cause the dependency files to contain invalid and confusing data, which is unhelpful while debugging build problems. Fix this using sed. Signed-off-by: Stephen Warren <swarren@nvidia.com> Reviewed-by: Masahiro Yamada <yamada.masahiro@socionext.com>

2019-02-27riscv: generic: Ensure that U-Boot runs within 4GB for 64bit systemsAnup Patel
On 64bit systems, the DRAM top can be easily beyond 4GB and U-Boot DMA mapping APIs will generate DMA addresses beyond 4GB. This breaks DMA programming in 32bit DMA capable devices (such as Cadence MACB ethernet). For example, If DRAM is more then 2GB on QEMU sifive_u machine then Cadence MACB ethernet stops working for U-Boot because it is a 32bit DMA capable device. To handle 32bit DMA capable devices on 64bit systems, we provide custom implementation of board_get_usable_ram_top() which ensures that usable ram top is not more then 4GB. This in-turn ensures that U-Boot always runs within 4GB hence DMA addresses generated by DMA mapping APIs will be within 4GB too.
