been a while since i wandered through the innards of u-boot so it's possible this is a silly question.
was just placed on a project that involves a xilinx zynqmp-based board, and need to upgrade the version of u-boot that's currently being used. as part of my perusal, i did a quick grep to see what existing boards were doing with any zynqmp-related header files, so i did this from the top of the current tree:
$ grep -r "include.*xilinx_zynqmp.*.h" * include/configs/xilinx_zynqmp_mini.h:#include <configs/xilinx_zynqmp.h> include/configs/xilinx_zynqmp_mini_emmc.h:#include <configs/xilinx_zynqmp_mini.h> include/configs/xilinx_zynqmp_mini_qspi.h:#include <configs/xilinx_zynqmp_mini.h> include/configs/xilinx_zynqmp_mini_nand.h:#include <configs/xilinx_zynqmp_mini.h> $
i'm aware of the ongoing migration of content from include/configs/*.h files to defconfig files, so the above seems to suggest, given the circular inclusion of those header files with no one else including them, that those files are no longer referenced.
my guess is that all that content was migrated to defconfigs but the header files were simply left there. is that a fair conclusion, or might there be something far more subtle i'm overlooking here?
Nope. All of them are used as configuration for configs/xilinx_zynqmp_mini* configurations. But as I am looking at it SYS_MALLOC_LEN can be converted to Kconfig.
The rest - SYS_SDRAM_SIZE/BASE and SYS_INIT_SP_ADDR haven't been converted yet. But patches welcome. Then we can remove _emmc, _qspi, _nand configurations and keep just mini.h one till other stuff are converted.
Thanks, Michal
