[Minios-devel] [UNIKRAFT PATCH 00/22] Follow up patches for Arm64 support series

[Wei Chen <wei.chen@xxxxxxx>]

As I promised in Arm64 support series, I will send follow up patches
to address some comments.

This series address following comments:
01: Remove the check of '--enable-default-pie' in Makefile.uk,
02: Use macro-ed helper to simplify ioreg_read/write,
03: Use the same declaration for _text and _end,
04: Address comments for D-Cache operation function,
05: Get virtual address bits from id_aa64mmfr0_el1.PARange,
06: Ensure stack alignment for exceptions from EL1,
07: Invalidate D-Cache for modified area only,
08: Disable D-Cache before doing any change,
09: Calculate L3 table and page table size by image size,
10: Remove a -Wstringop-overflow warning for strncpy.

Some comments that haven't been addressed:
01: Check the MIDR and avoid the erratum on affected platform
    via an alternative or jump table. -- This erreta framework
    is not only for Arm but also for x86. I think we'd better
    to discuss in community.
02: Enable FIFO support for PL011. My team mate Justin will
    handle it.

If I forgot anything please remind me.
