Hi all,
I numbered this v5 because this is still revolving around the same initial desire to cut the build time of an ARM64 kernel when toggling CONFIG_BLK_DEV_INITRD. This 4th version is basically the 3rd possible way to just get rid of __early_init_dt_declare_initrd() for ARM64.
I previously mentioned that I was working on making phys_initrd_start/phys_initrd_size generic across architectures that make use of it, which would cover ARM (32-bit), unicore32 and possibly arm64, but upon second glance, this does not necessarily help, or rather this patch series actually helps make a smoother conversion in the future.
Previous discussions/submissions list here:
v3: https://www.spinics.net/lists/arm-kernel/msg683566.html v2: https://lkml.org/lkml/2018/10/25/4
Changes in v5:
- incorporate Mike's version which properly takes care of command-line specified and FDT specified initrd location
Changes in v4:
- perform the physical to virtual initrd conversion straight within arm64_memblock_init() to get the correct memblock reservation to occur
Changes in v3: - attempt to change drivers/of/fdt.c to absorb ARM64's specific behavior
Changes in v2:
- put an /* empty */ comment in the asm-generic/initrd.h file - trim down the CC list to maximize the chances of people receiving this
