  This series is a set of patches which were originally part of RFC v1 series
[1] to add ACPI support in RISC-V interrupt controllers. Since these
patches are independent of the interrupt controllers, creating this new
series which helps to merge instead of waiting for big series.

This set of patches primarily adds support below ECR [2] which is approved
by the ASWG and adds below features.

- Get CBO block sizes from RHCT on ACPI based systems.

Additionally, the series contains a patch to improve acpi_os_ioremap().

[1] - https://lore.kernel.org/lkml/20230803175202.3173957-1-sunilvl@ventanamicro.com/
[2] - https://drive.google.com/file/d/1sKbOa8m1UZw1JkquZYe3F1zQBN1xXsaf/view?usp=sharing

Changes since v3:
	1) Added new patch to update return value of acpi_get_rhct() as suggested by Drew.
	2) Formatting fixes as suggested by Drew.
	3) Updated tags.

Changes since v2:
	1) Modified acpi_get_cbo_block_size() not to take cpu parameter
	   but follow same pattern as DT (Feedback from Samuel and Drew)
	2) Dropped timer patch from the series since it is already
	   applied.
	3) Selected ARCH_KEEP_MEMBLOCK only if ACPI (Feedback from
	   Alex).
	4) Added RB tags received so far except RHCT patch which has
	   changed quite significantly from previous version.

Changes since RFC v1:
	1) Separated the patches from interrupt controller support series.
	2) Addressed feedback from Andy and Drew.
	3) Rebased to Palmer's for-next tree.
	4) Added RB tags received on RFC v1.
