[PATCH 0/3] Boot RISC-V kernel from any 4KB aligned address

[Anup Patel]

From: Anup Patel <anup@xxxxxxxxxxxxxx>

This patchset primarily extends initial page table setup using fixmap
to boot Linux RISC-V kernel (64bit and 32bit) from any 4KB aligned address.
We also add 32bit defconfig to allow people to try 32bit Linux RISC-V
kernel as well.

The patchset is tested on SiFive Unleashed board and QEMU virt machine.

It can also be found in riscv_setup_vm_v1 branch of
https//github.com/avpatel/linux.git

Anup Patel (3):
  RISC-V: Add separate defconfig for 32bit systems
  RISC-V: Make setup_vm() independent of GCC code model
  RISC-V: Allow booting kernel from any 4KB aligned address
