* arm: lib: fix push/pop-section directivesStephen Warren2016-06-03-2/+2
| | | | | | | | | | | | | | | | | | | | | | | With the existing code, function symbols are defined in .text, and the body is defined in .text.xxx. This causes (at least some version of) the linker not to emit the function body into the final binary, since it's part of a different section to the symbols being referenced. This of course causes a wide variety of failures. This change moves the push/pop-section directives before the function symbols, and after any relate ENDPROC macro invocations, so that symbols and bodies are all in the "pushed" sections, and thus the function bodies are emitted into the binary. This solves (at least) the boot problems currently seen on Tegra systems that use SPL (i.e. all ARMv7 Tegras).

* arm: lib: Split asm symbols into different .text subsectionsMarek Vasut2016-06-02-0/+2
| | | | | | | | | | | | | Split each symbol in lib1funcs into different .text.foo section instead of placing all of them into plain .text . This allows the linker to collect and discard unused assembler symbols.

* arm: lib: Import __do_div64 from LinuxMarek Vasut2016-06-02-0/+212
Import __do_div64 from Linux 4.4.6 , commit 0d1912303e54ed1b2a371be0bba51c384dd57326 on arm32. This function is for some toolchains, which generate _udivmoddi4() for 64 bit division. Since we do not support stack unwinding, instead of importing the whole asm/unwind.h and all the baggage, this patch defines empty UNWIND() macro. This patch also defines CONFIG_THUMB2_KERNEL and CONFIG_ARM_ASM_UNIFIED which is necessary for correct build of these files both in ARM and Thumb mode, just like Linux does.
