Merge patch series "remove size limit on XIP kernel"

Nam Cao <namcao@linutronix.de> says:

Hi,

For XIP kernel, the writable data section is always at offset specified in
XIP_OFFSET, which is hard-coded to 32MB.

Unfortunately, this means the read-only section (placed before the
writable section) is restricted in size. This causes build failure if the
kernel gets too large.

This series remove the use of XIP_OFFSET one by one, then remove this
macro entirely at the end, with the goal of lifting this size restriction.

Also some cleanup and documentation along the way.

  riscv: remove limit on the size of read-only section for XIP kernel
  riscv: drop the use of XIP_OFFSET in create_kernel_page_table()
  riscv: drop the use of XIP_OFFSET in kernel_mapping_va_to_pa()
  riscv: drop the use of XIP_OFFSET in XIP_FIXUP_FLASH_OFFSET
  riscv: drop the use of XIP_OFFSET in XIP_FIXUP_OFFSET
  riscv: replace misleading va_kernel_pa_offset on XIP kernel
  riscv: don't export va_kernel_pa_offset in vmcoreinfo for XIP kernel
  riscv: cleanup XIP_FIXUP macro
  riscv: change XIP's kernel_map.size to be size of the entire kernel
