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,
11: Remove useless blank line,
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.
03: Compare the pointers of different type is behaviour undefined
04: Do obfuscates arithmetic for kernel image symbols.
If I forgot anything please remind me.

v3 -> v4:
1. Drop 04 and 24 patches in v3. patch 04 is gcc compiler
optimization related, not a blocking issue. The resolution is
under discussion. Patch 24 is not concerned.
2. Restore x18,x19 after using them in patch v4 14/23.
3. Fix IMAGE_ROUNDUP_SHIFT from 20 to 21 in patch v4 18/23.
4. lots of checkpatch warning.
v2 -> v3: Rebase to the latest upstream base.
v1 -> v2:
1. Add URL link for "Use macro-ed helper to simplify ioreg_read/write",
2. Invalidate & clean Cache for memory that would be used,
3. Improve code and commit comments for calculate pagebable size,
4. Use macros to replace hardcode values,
5. Use lsr/lsl to simplify 2MB round up,
6. Do obfuscates arithmetic for kernel image symbols,
7. Clean up kernel image symbols for C files.
