Gabor Juhos 55b0e261a4 ar71xx/lzma-loader: fix O32 ABI conformance
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.

Hauke Mehrtens e1ec8b76e9 ar71xx: fix build of lzma-loader with binutils 2.25.1
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.

Felix Fietkau 320aa30609 ar71xx: fix lzma-loader kernel command line passing
The generic kernel cmdline parser ignores argv[0], this caused a
regression for all lzma-loader based boards with linux 4.1
