microblaze: Enable GCC garbage collector for full U-Boot

2020-11-20T09:42:53+00:00

GCC's garbage collector works for Microblaze for quite a long time but none has enabled it. The same change has be done for example by commit fac4790491f6 ("arc: Eliminate unused code and data with GCC's garbage collector"). Before: text data bss dec hex filename 588760 33592 39192 661544 a1828 u-boot After: text data bss dec hex filename 504504 32164 38608 575276 8c72c u-boot Which saves almost 15% of memory footprint. Also group symbols/functions to proper section. Reported-by: Tom Rini Signed-off-by: Michal Simek

Remove CROSS_COMPILE default from arch/*/config.mk

2020-07-01T14:11:03+00:00

In order to support the compiler providing information used within Kconfig itself we cannot have the compiler be determined by arch/*/config.mk as we will not be able to evaluate that yet. Given that most documentation tells people to specify CROSS_COMPILE, remove these references.

SPDX: Convert all of our single license tags to Linux Kernel style

2018-05-07T13:34:12+00:00

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

kbuild: fix CROSS_COMPILE settings in config.mk

2014-03-04T17:15:30+00:00

The syntax CROSS_COMIPLE ?= does not work because config.mk is parsed after exporting CROSS_COMPILE. Like Linux Kernel's arch/$(ARCH)/Makefile, we must write as follows: ifeq ($(CROSS_COMPILE),) CROSS_COMPILE := endif Signed-off-by: Masahiro Yamada
