This converts the following to Kconfig: CONFIG_STANDALONE_LOAD_ADDR Signed-off-by: Tom Rini <trini@konsulko.com>
We can determine which of these we need given CPU_BIG_ENDIAN being enabled or not, so move that logic to Kconfig from config.mk. Cc: Alexey Brodkin <alexey.brodkin@synopsys.com> Cc: Eugeniy Paltsev <Eugeniy.Paltsev@synopsys.com> Signed-off-by: Tom Rini <trini@konsulko.com>
Align Kconfig and Kbuild logic to Linux 4.19 release with minimal impact
on files outside of this scope.
Our previous Kconfig sync was done by commit 5972ff077e0f ("kconfig /
kbuild: re-sync with Linux 4.18").
In this particular re-sync in order to keep clang support working a
number of related changes needed to be pulled in that had been missed
previously. Not all of these changes we easily traceable and so have
been omitted from the list below.
The imported Linux commits are:

Note that this adds new cleanup work to do in that we should adapt the
shared library support we have to what is now upstream.

It's a very rare if at all existing occasion when ARC CPU template is used as is w/o any changes - in the end it's a beauty and competitive advantage of ARC cores to be tailored for a particular use-case - and so it doesn't make a lot of sense to offer template-based "-mcpu" selection. Given for each and every platform we end-up adding quite a few more flags it's logical to move "-mcpu" selection to platform's definition as well which we exactly do here.

By default GCC puts global non-initialized variables in COMMON section. And we used to ignore existence of COMMON section in our linker scripts though smart LD silently appended it right after .bss. And the problem here is variables from COMMON section even though require zeroing in run-time were not zeroed as they were placed right after __bss_end symbol. It was a pure luck we never faced serious problem due to this, but now it is fixed. Now as for some other architectures we'll just force GCC to put those global variables in normal .bss section. This solution is much nicer than adding COMMON section to each and every linker script. Signed-off-by: Alexey Brodkin <abrodkin@synopsys.com>
Even though arc-linux- prefix is used in ARC prebuilt tools and in Buildroot there're other options like Linux distro cross-tools etc where prefix is different so let's not rely on this default. Signed-off-by: Alexey Brodkin <abrodkin@synopsys.com>
When U-Boot started using SPDX tags we were among the early adopters and there weren't a lot of other examples to borrow from. So we picked the area of the file that usually had a full license text and replaced it with an appropriate SPDX-License-Identifier: entry. Since then, the Linux Kernel has adopted SPDX tags and they place it as the very first line in a file (except where shebangs are used, then it's second line) and with slightly different comment styles than us. In part due to community overlap, in part due to better tag visibility and in part for other minor reasons, switch over to that style. This commit changes all instances where we have a single declared license in the tag as both the before and after are identical in tag contents. There's also a few places where I found we did not have a tag and have introduced one. Signed-off-by: Tom Rini <trini@konsulko.com>
Finally GCC's garbage collector works on ARC so let's use it. That's what I may see for HSDK: Before: text data bss dec hex filename 290153 10068 222616 522837 7fa55 u-boot After: text data bss dec hex filename 261999 9460 222360 493819 788fb u-boot Overall ~5% of memory footprint saved.

ARC Elf32 tools by default enable usage of so-called "small data" section or in ARC PRM parlance "GP-relative addressing". The idea is to put up to 2kB of frequently used data into a separate location and use indirect addressing via dedicated core register (GP). Where GP is used as a base for offset calculation. And so if "-msdata" toggle is passed to the compiler either explicitly or implicitly (that's Elf32 tools case) it will try to put some data in that "small data" area and then to calculate real offset from GP to be encoded in instructions we need to know the base value which liker gets from __SDATA_BEGIN__ symbol in hte linker script. In U-Boot we don't use that feature and linker script doesn't define __SDATA_BEGIN__ which gives us the following linkage error if we use Elf32 tools: ------------------------->8------------------- LD u-boot .../bin/arc-elf32-ld.bfd: Error: Linker symbol __SDATA_BEGIN__ not found .../bin/arc-elf32-ld.bfd: final link failed: Bad value ------------------------->8------------------- Note if uClibc or glibc tools are used that problem doesn't happen because usage of "small data section" is disabled by default as not very useful for bigger executables. Moreover GP is just another name of r26 so we're loosing 1 core register which is not used by the compiler as a generic register with "-msdata". Signed-off-by: Alexey Brodkin <abrodkin@synopsys.com>
