global_data: Ensure we have when symbols are not in Kconfig yet

2021-06-23T12:45:03Z

All symbols that are defined in Kconfig will always be defined (or not) prior to preprocessing due to the -include directive while building. However, symbols which are not yet migrated will only be defined (or not) once the board config.h is included, via . While the end goal must be to migrate all symbols, today we have cases where the size of gd will get mismatched within the build, based on include order. Mitigate this by making sure that any that uses symbols not in Kconfig does start with . Remove this when not needed.

ARM: make gd a function call for LTO and set via set_gd()

2021-05-24T18:21:30Z

On ARM, the gd pointer is stored in registers r9 / x18. For this the -ffixed-r9 / -ffixed-x18 flag is used when compiling, but using global register variables causes errors when building with LTO, and these errors are very difficult to overcome. Richard Biener says [1]: Note that global register vars shouldn't be used with LTO and if they are restricted to just a few compilation units the recommended fix is to build those CUs without -flto. We cannot do this for U-Boot since all CUs use -ffixed-reg flag. It seems that with LTO we could in fact store the gd pointer differently and gain performance or size benefit by allowing the compiler to use r9 / x18. But this would need more work. So for now, when building with LTO, go the clang way, and instead of declaring gd a global register variable, we make it a function call via macro.

The Thumb instruction `ldr` is able to move high registers only from armv7. For armv5 and armv6 we have to use `mov`. Signed-off-by: Marek Behún Reviewed-by: Simon Glass

treewide: Convert macro and uses of section(foo) to section("foo")

2021-05-24T18:21:30Z

This commit does the same thing as Linux commit 33def8498fdd. Use a more generic form for __section that requires quotes to avoid complications with clang and gcc differences. Remove the quote operator # from compiler_attributes.h __section macro. Convert all unquoted __section(foo) uses to quoted __section("foo"). Also convert __attribute__((section("foo"))) uses to __section("foo") even if the __attribute__ has multiple list entry forms.

sunxi: support asymmetric dual rank DRAM on A64/R40

2021-04-16T00:12:58Z

Previously we have known that R40 has a configuration register for its rank 1, which allows different configuration than rank 0. Reverse engineering of newest libdram of A64 from Allwinner shows that A64 has this register too. It's bit 0 (which enables dual rank in rank 0 configuration register) means a dedicated rank size setup is used for rank 1. Now, Pine64 scheduled to use a 3GiB LPDDR3 DRAM chip (which has 2GiB rank 0 and 1GiB rank 1) on PinePhone, that makes asymmetric dual rank DRAM support necessary. Add this support. The code could support both A64 and R40, but because dual rank detection is broken on R40 now, we cannot really use it on R40 currently.
