Subject: [PATCH v2 0/4] Assorted fixes for RV32

This series fixes various issues observed in latest kernel on RV32.
The first two patches fixes an resource tree introduced in 5.11-rc1
while the last two fixes the case where 2GB physical memory is used
on RV32.

There are may be better way to fix the issue pointed out in PATCH 3
as it seems a generic kernel issue where kernel pointers can not use
last 4k of addressable memory. I am open to other better alternate
suggestions.

Changes from v1->v2:
1. Added Reviewed/Tested by tags.
2. Replaced PHYS_ADDR_MAX with explicit __pa(~(ulong)0).

Atish Patra (4):
RISC-V: Do not allocate memblock while iterating reserved memblocks
RISC-V: Set current memblock limit
RISC-V: Fix L1_CACHE_BYTES for RV32
RISC-V: Fix maximum allowed phsyical memory for RV32
