*	ar71xx: lzma loader use LTO	Julien Dusser	2017-10-24	1	-3/+5
\| \| \| \| \| \| \|	Change the Makefile to use LTO for better code optimisations. Gains are very low, only 270 bytes saved, but it's only Makefile changes. Signed-off-by: Julien Dusser <julien.dusser@free.fr>
*	ar71xx: fix lzma loader performance issues	Julien Dusser	2017-10-24	1	-0/+13
\| \| \| \| \| \| \| \| \| \| \|	Some bootloaders set a cache cohenrency to a very slow mode. Use code from Linux kernel to set it to "Cacheable, noncoherent, write-back, write allocate". Perfomance impact is significant on TP-Link EAP245 board, kernel decompression time fall from 33 seconds to less than 1. Signed-off-by: Julien Dusser <julien.dusser@free.fr>
*	ar71xx/lzma-loader: fix O32 ABI conformance	Gabor Juhos	2016-01-17	1	-0/+3
\| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \|	According to the calling convention of the o32 ABI the caller function must reserve stack space for $a0-$a3 registers in case the callee needs to save its arguments. The assembly code of the loader does not reserve stack space for these registers thus when the 'loader_main' function needs to save its arguments, those will be stored in the 'workspace' area instead of the stack. Because the workspace area is also used by other part of the code, the saved register values gets overwritten and this often leads to failed kernel boots. Fix the code to reserve stack space for the registers to avoid this error. Signed-off-by: Gabor Juhos <juhosg@openwrt.org> SVN-Revision: 48279
*	ar71xx: ensure that LOADADDR is passed to lzma-loader	Felix Fietkau	2016-01-03	1	-0/+2
\| \| \| \| \| \|	Signed-off-by: Felix Fietkau <nbd@openwrt.org> SVN-Revision: 48101
*	ar71xx: fix build of lzma-loader with binutils 2.25.1	Hauke Mehrtens	2015-09-12	1	-1/+2
\| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \|	To make the lzma-loader build with binutils 2.25.1 it is needed to remove the .MIPS.abiflags section otherwise I get the following compile error: mips-openwrt-linux-musl-objcopy -O binary -R .reginfo -R .note -R .comment -R .mdebug -S loader loader.bin mips-openwrt-linux-musl-objcopy: Warning: Writing section `.text' to huge (ie negative) file offset 0xffffffff80a00000. mips-openwrt-linux-musl-objcopy:loader.bin[.text]: File truncated This should close #20487.

*	ar71xx: fix lzma-loader kernel command line passing	Felix Fietkau	2015-08-02	1	-1/+2
\| \| \| \| \| \| \| \| \|	The generic kernel cmdline parser ignores argv[0], this caused a regression for all lzma-loader based boards with linux 4.1 Signed-off-by: Felix Fietkau <nbd@openwrt.org> SVN-Revision: 46544
*	ar71xx/image: relink loader.elf image to LOADADDR	Gabor Juhos	2012-11-20	2	-5/+21
\| \| \| \| \| \| \| \| \|	This allows to load the resulting image directly from RouterBOOT. Signed-off-by: Gabor Juhos <juhosg@openwrt.org> SVN-Revision: 34271
*	ar71xx: image: stop the switch from the lzma-loader on the TL-WR1043ND	Gabor Juhos	2012-08-02	2	-0/+745

*	ar71xx: image: allow to use board specific code in the lzma-loader	Gabor Juhos	2012-08-02	2	-1/+8
