Hi all
I am trying to find out the following symbols in RISC V kernel code
1. Kernel decompressor symbols in RISC V kernel, which are equivalent
to ZTEXTADDR, ZBSSADDR, ZRELADDR, INITRD_PHYS, INITRD_VIRT,
PARAMS_PHYS in ARM Arch.
2 .Kernel symbols in RISC V equivalent to PHYS_OFFSET, PAGE_OFFSET,
TASK_SIZE, TEXTADDR, DATAADDR, VMALLOC_START / VMALLOC_END,
VMALLOC_OFFSET in ARM arch.
3. Architecture specfic macros in RISC V equivalent to BOOT_MEM(param,
vio, io), BOOT_PARAMS,FIXUP(func), MAPIO(func), INITIRQ(func) in ARM
Arch.
Can you suggest me where will find the same , if RISC V is using
different kind of symbols/params for the same usage, what are names of
the same & where they are located.
Thanks & Regards
Satish G

We don't have a self-decompressing image.

These should largely be the same, you can grep for them.

These are handled in more general ways: boot params are passed via /chosen in
the device tree, for example.
